Merge branch 'for-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo:
"Support for some new embedded controllers.
A couple late (<= a week) fixes have stable cc'd and one patch ("SATA:
MV: Add support for the optional PHYs") got committed yesterday
because otherwise the resulting kernel would fail boot on an embedded
board due to interdependent changes in its platform tree.
Other than that, nothing too noteworthy"

This may allow the driver to support more hardware than
was included in the driver's static device ID support
table at compile time. The format for the device ID is:
- idVendor idProduct bInterfaceClass.
+ idVendor idProduct bInterfaceClass RefIdVendor RefIdProduct
The vendor ID and device ID fields are required, the
- interface class is optional.
+ rest is optional. The Ref* tuple can be used to tell the
+ driver to use the same driver_data for the new device as
+ it is used for the reference device.
Upon successfully adding an ID, the driver will probe
for the device and attempt to bind to it. For example:
# echo "8086 10f5" > /sys/bus/usb/drivers/foo/new_id
+ Here add a new device (0458:7045) using driver_data from
+ an already supported device (0458:704c):
+ # echo "0458 7045 0 0458 704c" > /sys/bus/usb/drivers/foo/new_id

Reading from this file will list all dynamically added
device IDs in the same format, with one entry per
line. For example:

+Description: Switching efi runtime services to virtual mode requires
+ that all efi memory ranges which have the runtime attribute
+ bit set to be mapped to virtual addresses.
+
+ The efi runtime services can only be switched to virtual
+ mode once without rebooting. The kexec kernel must maintain
+ the same physical to virtual address mappings as the first
+ kernel. The mappings are exported to sysfs so userspace tools
+ can reassemble them and pass them into the kexec kernel.
+
+ /sys/firmware/efi/runtime-map/ is the directory the kernel
+ exports that information in.
+
+ subdirectories are named with the number of the memory range:
+
+ /sys/firmware/efi/runtime-map/0
+ /sys/firmware/efi/runtime-map/1
+ /sys/firmware/efi/runtime-map/2
+ /sys/firmware/efi/runtime-map/3
+ ...
+
+ Each subdirectory contains five files:
+
+ attribute : The attributes of the memory range.
+ num_pages : The size of the memory range in pages.
+ phys_addr : The physical address of the memory range.
+ type : The type of the memory range.
+ virt_addr : The virtual address of the memory range.
+
+ Above values are all hexadecimal numbers with the '0x' prefix.

+Null block device driver
+================================================================================
+
+I. Overview
+
+The null block device (/dev/nullb*) is used for benchmarking the various
+block-layer implementations. It emulates a block device of X gigabytes in size.
+The following instances are possible:
+
+ Single-queue block-layer
+ - Request-based.
+ - Single submission queue per device.
+ - Implements IO scheduling algorithms (CFQ, Deadline, noop).
+ Multi-queue block-layer
+ - Request-based.
+ - Configurable submission queues per device.
+ No block-layer (Known as bio-based)
+ - Bio-based. IO requests are submitted directly to the device driver.
+ - Directly accepts bio data structure and returns them.
+
+All of them have a completion queue for each core in the system.
+
+II. Module parameters applicable for all instances:
+
+queue_mode=[0-2]: Default: 2-Multi-queue
+ Selects which block-layer the module should instantiate with.
+
+ 0: Bio-based.
+ 1: Single-queue.
+ 2: Multi-queue.
+
+home_node=[0--nr_nodes]: Default: NUMA_NO_NODE
+ Selects what CPU node the data structures are allocated from.
+
+gb=[Size in GB]: Default: 250GB
+ The size of the device reported to the system.
+
+bs=[Block size (in bytes)]: Default: 512 bytes
+ The block size reported to the system.
+
+nr_devices=[Number of devices]: Default: 2
+ Number of block devices instantiated. They are instantiated as /dev/nullb0,
+ etc.
+
+irq_mode=[0-2]: Default: 1-Soft-irq
+ The completion mode used for completing IOs to the block-layer.
+
+ 0: None.
+ 1: Soft-irq. Uses IPI to complete IOs across CPU nodes. Simulates the overhead
+ when IOs are issued from another CPU node than the home the device is
+ connected to.
+ 2: Timer: Waits a specific period (completion_nsec) for each IO before
+ completion.
+
+completion_nsec=[ns]: Default: 10.000ns
+ Combined with irq_mode=2 (timer). The time each completion event must wait.
+
+submit_queues=[0..nr_cpus]:
+ The number of submission queues attached to the device driver. If unset, it
+ defaults to 1 on single-queue and bio-based instances. For multi-queue,
+ it is ignored when use_per_node_hctx module parameter is 1.
+
+hw_queue_depth=[0..qdepth]: Default: 64
+ The hardware queue depth of the device.
+
+III: Multi-queue specific parameters
+
+use_per_node_hctx=[0/1]: Default: 0
+ 0: The number of submit queues are set to the value of the submit_queues
+ parameter.
+ 1: The multi-queue block layer is instantiated with a hardware dispatch
+ queue for each CPU node in the system.

-2.4 Notification API
---------------------
-
-There is mechanism which allows to get notifications about changing
-status of a cgroup.
-
-To register a new notification handler you need to:
- - create a file descriptor for event notification using eventfd(2);
- - open a control file to be monitored (e.g. memory.usage_in_bytes);
- - write "<event_fd> <control_fd> <args>" to cgroup.event_control.
- Interpretation of args is defined by control file implementation;
-
-eventfd will be woken up by control file implementation or when the
-cgroup is removed.
-
-To unregister a notification handler just close eventfd.
-
-NOTE: Support of notifications should be implemented for the control
-file. See documentation for the subsystem.

+- interrupt-controller: Marks the device node as a interrupt controller.

+ interrupts are generated regardless of the bank that an input change
+ occured on. If it is not set, the interrupt are only generated for the
+ bank they belong to.
+ On devices with only one interrupt output this property is useless.

+The MMC Host Controller on TI OMAP1 and 2420 family provides
+an interface for MMC, SD, and SDIO types of memory cards.
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the omap mmc driver.
+
+Note that this driver will not work with omap2430 or later omaps,
+please see the omap hsmmc driver for the current omaps.
+
+Required properties:
+- compatible: Must be "ti,omap2420-mmc", for OMAP2420 controllers
+- ti,hwmods: For 2420, must be "msdi<n>", where n is controller
+ instance starting 1
+
+Examples:
+
+ msdi1: mmc@4809c000 {
+ compatible = "ti,omap2420-mmc";
+ ti,hwmods = "msdi1";
+ reg = <0x4809c000 0x80>;
+ interrupts = <83>;
+ dmas = <&sdma 61 &sdma 62>;
+ dma-names = "tx", "rx";

+Broadcom Capri Pin Controller
+
+This is a pin controller for the Broadcom BCM281xx SoC family, which includes
+BCM11130, BCM11140, BCM11351, BCM28145, and BCM28155 SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "brcm,capri-pinctrl".
+- reg: Base address of the PAD Controller register block and the size
+ of the block.
+
+For example, the following is the bare minimum node:
+
+ pinctrl@35004800 {
+ compatible = "brcm,capri-pinctrl";
+ reg = <0x35004800 0x430>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux and/or pin configuration for an
+arbitrary number of pins. The name of the pin group node is optional and not
+used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Each pin controlled by this pin controller belong to one of three types:
+Standard, I2C, and HDMI. Each type accepts a different set of pin config
+properties. A list of pins and their types is provided below.
+
+Required Properties (applicable to all pins):
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to
+ be configured by this node.
+
+Optional Properties (for standard pins):
+
+- function: String. Specifies the pin mux selection. Values
+ must be one of: "alt1", "alt2", "alt3", "alt4"
+- input-schmitt-enable: No arguments. Enable schmitt-trigger mode.
+- input-schmitt-disable: No arguments. Disable schmitt-trigger mode.
+- bias-pull-up: No arguments. Pull up on pin.
+- bias-pull-down: No arguments. Pull down on pin.
+- bias-disable: No arguments. Disable pin bias.
+- slew-rate: Integer. Meaning depends on configured pin mux:
+ *_SCL or *_SDA:
+ 0: Standard(100kbps)& Fast(400kbps) mode
+ 1: Highspeed (3.4Mbps) mode
+ IC_DM or IC_DP:
+ 0: normal slew rate
+ 1: fast slew rate
+ Otherwise:
+ 0: fast slew rate
+ 1: normal slew rate
+- input-enable: No arguements. Enable input (does not affect
+ output.)
+- input-disable: No arguements. Disable input (does not affect
+ output.)
+- drive-strength: Integer. Drive strength in mA. Valid values are
+ 2, 4, 6, 8, 10, 12, 14, 16 mA.
+
+Optional Properties (for I2C pins):
+
+- function: String. Specifies the pin mux selection. Values
+ must be one of: "alt1", "alt2", "alt3", "alt4"
+- bias-pull-up: Integer. Pull up strength in Ohm. There are 3
+ pull-up resisitors (1.2k, 1.8k, 2.7k) available
+ in parallel for I2C pins, so the valid values
+ are: 568, 720, 831, 1080, 1200, 1800, 2700 Ohm.
+- bias-disable: No arguments. Disable pin bias.
+- slew-rate: Integer. Meaning depends on configured pin mux:
+ *_SCL or *_SDA:
+ 0: Standard(100kbps)& Fast(400kbps) mode
+ 1: Highspeed (3.4Mbps) mode
+ IC_DM or IC_DP:
+ 0: normal slew rate
+ 1: fast slew rate
+ Otherwise:
+ 0: fast slew rate
+ 1: normal slew rate
+- input-enable: No arguements. Enable input (does not affect
+ output.)
+- input-disable: No arguements. Disable input (does not affect
+ output.)
+
+Optional Properties (for HDMI pins):
+
+- function: String. Specifies the pin mux selection. Values
+ must be one of: "alt1", "alt2", "alt3", "alt4"
+- slew-rate: Integer. Controls slew rate.
+ 0: Standard(100kbps)& Fast(400kbps) mode
+ 1: Highspeed (3.4Mbps) mode
+- input-enable: No arguements. Enable input (does not affect
+ output.)
+- input-disable: No arguements. Disable input (does not affect
+ output.)
+
+Example:
+// pin controller node
+pinctrl@35004800 {
+ compatible = "brcm,capri-pinctrl";
+ reg = <0x35004800 0x430>;
+
+ // pin configuration node
+ dev_a_default: dev_a_active {
+ //group node defining 1 standard pin
+ grp_1 {
+ pins = "std_pin1";
+ function = "alt1";
+ input-schmitt-enable;
+ bias-disable;
+ slew-rate = <1>;
+ drive-strength = <4>;
+ };
+
+ // group node defining 2 I2C pins
+ grp_2 {
+ pins = "i2c_pin1", "i2c_pin2";
+ function = "alt2";
+ bias-pull-up = <720>;
+ input-enable;
+ };
+
+ // group node defining 2 HDMI pins
+ grp_3 {
+ pins = "hdmi_pin1", "hdmi_pin2";
+ function = "alt3";
+ slew-rate = <1>;
+ };
+
+ // other pin group nodes
+ ...
+ };
+
+ // other pin configuration nodes
+ ...
+};
+
+In the example above, "dev_a_active" is a pin configuration node with a number
+of sub-nodes. In the pin group node "grp_1", one pin, "std_pin1", is defined in
+the "pins" property. Thus, the remaining properties in the "grp_1" node applies
+only to this pin, including the following settings:
+ - setting pinmux to "alt1"
+ - enabling schmitt-trigger (hystersis) mode
+ - disabling pin bias
+ - setting the slew-rate to 1
+ - setting the drive strength to 4 mA
+Note that neither "input-enable" nor "input-disable" was specified - the pinctrl
+subsystem will therefore leave this property unchanged from whatever state it
+was in before applying these changes.
+
+The "pins" property in the pin group node "grp_2" specifies two pins -
+"i2c_pin1" and "i2c_pin2"; the remaining properties in this pin group node,
+therefore, applies to both of these pins. The properties include:
+ - setting pinmux to "alt2"
+ - setting pull-up resistance to 720 Ohm (ie. enabling 1.2k and 1.8k resistors
+ in parallel)
+ - enabling both pins' input
+"slew-rate" is not specified in this pin group node, so the slew-rate for these
+pins are left as-is.
+
+Finally, "grp_3" defines two HDMI pins. The following properties are applied to
+both pins:
+ - setting pinmux to "alt3"
+ - setting slew-rate to 1; for HDMI pins, this corresponds to the 3.4 Mbps
+ Highspeed mode
+The input is neither enabled or disabled, and is left untouched.

+Qualcomm MSM8974 TLMM block
+
+Required properties:
+- compatible: "qcom,msm8x74-pinctrl"
+- reg: Should be the base address and length of the TLMM block.
+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+ The first cell is the gpio pin number and the
+ second cell is used for optional parameters.
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength.
+
+Non-empty subnodes must specify the 'pins' property.
+Note that not all properties are valid for all pins.
+
+
+Valid values for qcom,pins are:
+ gpio0-gpio145
+ Supports mux, bias and drive-strength
+
+ sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd, sdc2_data
+ Supports bias and drive-strength
+
+Valid values for qcom,function are:
+ blsp_i2c2, blsp_i2c6, blsp_i2c11, blsp_spi1, blsp_uart2, blsp_uart8, slimbus
+
+ (Note that this is not yet the complete list of functions)
+
+
+
+Example:
+
+ msmgpio: pinctrl@fd510000 {
+ compatible = "qcom,msm8974-pinctrl";
+ reg = <0xfd510000 0x4000>;

+
+Device Driver Design Patterns
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This document describes a few common design patterns found in device drivers.
+It is likely that subsystem maintainers will ask driver developers to
+conform to these design patterns.
+
+1. State Container
+2. container_of()
+
+
+1. State Container
+~~~~~~~~~~~~~~~~~~
+
+While the kernel contains a few device drivers that assume that they will
+only be probed() once on a certain system (singletons), it is custom to assume
+that the device the driver binds to will appear in several instances. This
+means that the probe() function and all callbacks need to be reentrant.
+
+The most common way to achieve this is to use the state container design
+pattern. It usually has this form:
+
+struct foo {
+ spinlock_t lock; /* Example member */
+ (...)
+};
+
+static int foo_probe(...)
+{
+ struct foo *foo;
+
+ foo = devm_kzalloc(dev, sizeof(*foo), GFP_KERNEL);
+ if (!foo)
+ return -ENOMEM;
+ spin_lock_init(&foo->lock);
+ (...)
+}
+
+This will create an instance of struct foo in memory every time probe() is
+called. This is our state container for this instance of the device driver.
+Of course it is then necessary to always pass this instance of the
+state around to all functions that need access to the state and its members.
+
+For example, if the driver is registering an interrupt handler, you would
+pass around a pointer to struct foo like this:
+
+static irqreturn_t foo_handler(int irq, void *arg)
+{
+ struct foo *foo = arg;
+ (...)
+}
+
+static int foo_probe(...)
+{
+ struct foo *foo;
+
+ (...)
+ ret = request_irq(irq, foo_handler, 0, "foo", foo);
+}
+
+This way you always get a pointer back to the correct instance of foo in
+your interrupt handler.
+
+
+2. container_of()
+~~~~~~~~~~~~~~~~~
+
+Continuing on the above example we add an offloaded work:
+
+struct foo {
+ spinlock_t lock;
+ struct workqueue_struct *wq;
+ struct work_struct offload;
+ (...)
+};
+
+static void foo_work(struct work_struct *work)
+{
+ struct foo *foo = container_of(work, struct foo, offload);
+
+ (...)
+}
+
+static irqreturn_t foo_handler(int irq, void *arg)
+{
+ struct foo *foo = arg;
+
+ queue_work(foo->wq, &foo->offload);
+ (...)
+}
+
+static int foo_probe(...)
+{
+ struct foo *foo;
+
+ foo->wq = create_singlethread_workqueue("foo-wq");
+ INIT_WORK(&foo->offload, foo_work);
+ (...)
+}
+
+The design pattern is the same for an hrtimer or something similar that will
+return a single argument which is a pointer to a struct member in the
+callback.
+
+container_of() is a macro defined in <linux/kernel.h>
+
+What container_of() does is to obtain a pointer to the containing struct from
+a pointer to a member by a simple subtraction using the offsetof() macro from
+standard C, which allows something similar to object oriented behaviours.
+Notice that the contained member must not be a pointer, but an actual member
+for this to work.
+
+We can see here that we avoid having global pointers to our struct foo *
+instance this way, while still keeping the number of parameters passed to the
+work function to a single pointer.

+GPIO Mappings
+=============
+
+This document explains how GPIOs can be assigned to given devices and functions.
+Note that it only applies to the new descriptor-based interface. For a
+description of the deprecated integer-based GPIO interface please refer to
+gpio-legacy.txt (actually, there is no real mapping possible with the old
+interface; you just fetch an integer from somewhere and request the
+corresponding GPIO.
+
+Platforms that make use of GPIOs must select ARCH_REQUIRE_GPIOLIB (if GPIO usage
+is mandatory) or ARCH_WANT_OPTIONAL_GPIOLIB (if GPIO support can be omitted) in
+their Kconfig. Then, how GPIOs are mapped depends on what the platform uses to
+describe its hardware layout. Currently, mappings can be defined through device
+tree, ACPI, and platform data.
+
+Device Tree
+-----------
+GPIOs can easily be mapped to devices and functions in the device tree. The
+exact way to do it depends on the GPIO controller providing the GPIOs, see the
+device tree bindings for your controller.
+
+GPIOs mappings are defined in the consumer device's node, in a property named
+<function>-gpios, where <function> is the function the driver will request
+through gpiod_get(). For example:
+
+ foo_device {
+ compatible = "acme,foo";
+ ...
+ led-gpios = <&gpio 15 GPIO_ACTIVE_HIGH>, /* red */
+ <&gpio 16 GPIO_ACTIVE_HIGH>, /* green */
+ <&gpio 17 GPIO_ACTIVE_HIGH>; /* blue */
+
+ power-gpio = <&gpio 1 GPIO_ACTIVE_LOW>;
+ };
+
+This property will make GPIOs 15, 16 and 17 available to the driver under the
+"led" function, and GPIO 1 as the "power" GPIO:
+
+ struct gpio_desc *red, *green, *blue, *power;
+
+ red = gpiod_get_index(dev, "led", 0);
+ green = gpiod_get_index(dev, "led", 1);
+ blue = gpiod_get_index(dev, "led", 2);
+
+ power = gpiod_get(dev, "power");
+
+The led GPIOs will be active-high, while the power GPIO will be active-low (i.e.
+gpiod_is_active_low(power) will be true).
+
+ACPI
+----
+ACPI does not support function names for GPIOs. Therefore, only the "idx"
+argument of gpiod_get_index() is useful to discriminate between GPIOs assigned
+to a device. The "con_id" argument can still be set for debugging purposes (it
+will appear under error messages as well as debug and sysfs nodes).
+
+Platform Data
+-------------
+Finally, GPIOs can be bound to devices and functions using platform data. Board
+files that desire to do so need to include the following header:
+
+ #include <linux/gpio/driver.h>
+
+GPIOs are mapped by the means of tables of lookups, containing instances of the
+gpiod_lookup structure. Two macros are defined to help declaring such mappings:
+
+ GPIO_LOOKUP(chip_label, chip_hwnum, dev_id, con_id, flags)
+ GPIO_LOOKUP_IDX(chip_label, chip_hwnum, dev_id, con_id, idx, flags)
+
+where
+
+ - chip_label is the label of the gpiod_chip instance providing the GPIO
+ - chip_hwnum is the hardware number of the GPIO within the chip
+ - dev_id is the identifier of the device that will make use of this GPIO. It
+ can be NULL, in which case it will be matched for calls to gpiod_get()
+ with a NULL device.
+ - con_id is the name of the GPIO function from the device point of view. It
+ can be NULL, in which case it will match any function.
+ - idx is the index of the GPIO within the function.
+ - flags is defined to specify the following properties:
+ * GPIOF_ACTIVE_LOW - to configure the GPIO as active-low
+ * GPIOF_OPEN_DRAIN - GPIO pin is open drain type.
+ * GPIOF_OPEN_SOURCE - GPIO pin is open source type.
+
+In the future, these flags might be extended to support more properties.
+
+Note that GPIO_LOOKUP() is just a shortcut to GPIO_LOOKUP_IDX() where idx = 0.
+
+A lookup table can then be defined as follows, with an empty entry defining its
+end:
+
+struct gpiod_lookup_table gpios_table = {
+ .dev_id = "foo.0",
+ .table = {
+ GPIO_LOOKUP_IDX("gpio.0", 15, "led", 0, GPIO_ACTIVE_HIGH),
+ GPIO_LOOKUP_IDX("gpio.0", 16, "led", 1, GPIO_ACTIVE_HIGH),
+ GPIO_LOOKUP_IDX("gpio.0", 17, "led", 2, GPIO_ACTIVE_HIGH),
+ GPIO_LOOKUP("gpio.0", 1, "power", GPIO_ACTIVE_LOW),
+ { },
+ },
+};
+
+And the table can be added by the board code as follows:
+
+ gpiod_add_lookup_table(&gpios_table);
+
+The driver controlling "foo.0" will then be able to obtain its GPIOs as follows:
+
+ struct gpio_desc *red, *green, *blue, *power;
+
+ red = gpiod_get_index(dev, "led", 0);
+ green = gpiod_get_index(dev, "led", 1);
+ blue = gpiod_get_index(dev, "led", 2);
+
+ power = gpiod_get(dev, "power");
+ gpiod_direction_output(power, 1);
+
+Since the "power" GPIO is mapped as active-low, its actual signal will be 0
+after this code. Contrary to the legacy integer GPIO interface, the active-low
+property is handled during mapping and is thus transparent to GPIO consumers.

+GPIO Descriptor Consumer Interface
+==================================
+
+This document describes the consumer interface of the GPIO framework. Note that
+it describes the new descriptor-based interface. For a description of the
+deprecated integer-based GPIO interface please refer to gpio-legacy.txt.
+
+
+Guidelines for GPIOs consumers
+==============================
+
+Drivers that can't work without standard GPIO calls should have Kconfig entries
+that depend on GPIOLIB. The functions that allow a driver to obtain and use
+GPIOs are available by including the following file:
+
+ #include <linux/gpio/consumer.h>
+
+All the functions that work with the descriptor-based GPIO interface are
+prefixed with gpiod_. The gpio_ prefix is used for the legacy interface. No
+other function in the kernel should use these prefixes.
+
+
+Obtaining and Disposing GPIOs
+=============================
+
+With the descriptor-based interface, GPIOs are identified with an opaque,
+non-forgeable handler that must be obtained through a call to one of the
+gpiod_get() functions. Like many other kernel subsystems, gpiod_get() takes the
+device that will use the GPIO and the function the requested GPIO is supposed to
+fulfill:
+
+ struct gpio_desc *gpiod_get(struct device *dev, const char *con_id)
+
+If a function is implemented by using several GPIOs together (e.g. a simple LED
+device that displays digits), an additional index argument can be specified:
+
+ struct gpio_desc *gpiod_get_index(struct device *dev,
+ const char *con_id, unsigned int idx)
+
+Both functions return either a valid GPIO descriptor, or an error code checkable
+with IS_ERR() (they will never return a NULL pointer). -ENOENT will be returned
+if and only if no GPIO has been assigned to the device/function/index triplet,
+other error codes are used for cases where a GPIO has been assigned but an error
+occured while trying to acquire it. This is useful to discriminate between mere
+errors and an absence of GPIO for optional GPIO parameters.
+
+Device-managed variants of these functions are also defined:
+
+ struct gpio_desc *devm_gpiod_get(struct device *dev, const char *con_id)
+
+ struct gpio_desc *devm_gpiod_get_index(struct device *dev,
+ const char *con_id,
+ unsigned int idx)
+
+A GPIO descriptor can be disposed of using the gpiod_put() function:
+
+ void gpiod_put(struct gpio_desc *desc)
+
+It is strictly forbidden to use a descriptor after calling this function. The
+device-managed variant is, unsurprisingly:
+
+ void devm_gpiod_put(struct device *dev, struct gpio_desc *desc)
+
+
+Using GPIOs
+===========
+
+Setting Direction
+-----------------
+The first thing a driver must do with a GPIO is setting its direction. This is
+done by invoking one of the gpiod_direction_*() functions:
+
+ int gpiod_direction_input(struct gpio_desc *desc)
+ int gpiod_direction_output(struct gpio_desc *desc, int value)
+
+The return value is zero for success, else a negative errno. It should be
+checked, since the get/set calls don't return errors and since misconfiguration
+is possible. You should normally issue these calls from a task context. However,
+for spinlock-safe GPIOs it is OK to use them before tasking is enabled, as part
+of early board setup.
+
+For output GPIOs, the value provided becomes the initial output value. This
+helps avoid signal glitching during system startup.
+
+A driver can also query the current direction of a GPIO:
+
+ int gpiod_get_direction(const struct gpio_desc *desc)
+
+This function will return either GPIOF_DIR_IN or GPIOF_DIR_OUT.
+
+Be aware that there is no default direction for GPIOs. Therefore, **using a GPIO
+without setting its direction first is illegal and will result in undefined
+behavior!**
+
+
+Spinlock-Safe GPIO Access
+-------------------------
+Most GPIO controllers can be accessed with memory read/write instructions. Those
+don't need to sleep, and can safely be done from inside hard (non-threaded) IRQ
+handlers and similar contexts.
+
+Use the following calls to access GPIOs from an atomic context:
+
+ int gpiod_get_value(const struct gpio_desc *desc);
+ void gpiod_set_value(struct gpio_desc *desc, int value);
+
+The values are boolean, zero for low, nonzero for high. When reading the value
+of an output pin, the value returned should be what's seen on the pin. That
+won't always match the specified output value, because of issues including
+open-drain signaling and output latencies.
+
+The get/set calls do not return errors because "invalid GPIO" should have been
+reported earlier from gpiod_direction_*(). However, note that not all platforms
+can read the value of output pins; those that can't should always return zero.
+Also, using these calls for GPIOs that can't safely be accessed without sleeping
+(see below) is an error.
+
+
+GPIO Access That May Sleep
+--------------------------
+Some GPIO controllers must be accessed using message based buses like I2C or
+SPI. Commands to read or write those GPIO values require waiting to get to the
+head of a queue to transmit a command and get its response. This requires
+sleeping, which can't be done from inside IRQ handlers.
+
+Platforms that support this type of GPIO distinguish them from other GPIOs by
+returning nonzero from this call:
+
+ int gpiod_cansleep(const struct gpio_desc *desc)
+
+To access such GPIOs, a different set of accessors is defined:
+
+ int gpiod_get_value_cansleep(const struct gpio_desc *desc)
+ void gpiod_set_value_cansleep(struct gpio_desc *desc, int value)
+
+Accessing such GPIOs requires a context which may sleep, for example a threaded
+IRQ handler, and those accessors must be used instead of spinlock-safe
+accessors without the cansleep() name suffix.
+
+Other than the fact that these accessors might sleep, and will work on GPIOs
+that can't be accessed from hardIRQ handlers, these calls act the same as the
+spinlock-safe calls.
+
+
+Active-low State and Raw GPIO Values
+------------------------------------
+Device drivers like to manage the logical state of a GPIO, i.e. the value their
+device will actually receive, no matter what lies between it and the GPIO line.
+In some cases, it might make sense to control the actual GPIO line value. The
+following set of calls ignore the active-low property of a GPIO and work on the
+raw line value:
+
+ int gpiod_get_raw_value(const struct gpio_desc *desc)
+ void gpiod_set_raw_value(struct gpio_desc *desc, int value)
+ int gpiod_get_raw_value_cansleep(const struct gpio_desc *desc)
+ void gpiod_set_raw_value_cansleep(struct gpio_desc *desc, int value)
+
+The active-low state of a GPIO can also be queried using the following call:
+
+ int gpiod_is_active_low(const struct gpio_desc *desc)
+
+Note that these functions should only be used with great moderation ; a driver
+should not have to care about the physical line level.
+
+GPIOs mapped to IRQs
+--------------------
+GPIO lines can quite often be used as IRQs. You can get the IRQ number
+corresponding to a given GPIO using the following call:
+
+ int gpiod_to_irq(const struct gpio_desc *desc)
+
+It will return an IRQ number, or an negative errno code if the mapping can't be
+done (most likely because that particular GPIO cannot be used as IRQ). It is an
+unchecked error to use a GPIO that wasn't set up as an input using
+gpiod_direction_input(), or to use an IRQ number that didn't originally come
+from gpiod_to_irq(). gpiod_to_irq() is not allowed to sleep.
+
+Non-error values returned from gpiod_to_irq() can be passed to request_irq() or
+free_irq(). They will often be stored into IRQ resources for platform devices,
+by the board-specific initialization code. Note that IRQ trigger options are
+part of the IRQ interface, e.g. IRQF_TRIGGER_FALLING, as are system wakeup
+capabilities.
+
+
+Interacting With the Legacy GPIO Subsystem
+==========================================
+Many kernel subsystems still handle GPIOs using the legacy integer-based
+interface. Although it is strongly encouraged to upgrade them to the safer
+descriptor-based API, the following two functions allow you to convert a GPIO
+descriptor into the GPIO integer namespace and vice-versa:
+
+ int desc_to_gpio(const struct gpio_desc *desc)
+ struct gpio_desc *gpio_to_desc(unsigned gpio)
+
+The GPIO number returned by desc_to_gpio() can be safely used as long as the
+GPIO descriptor has not been freed. All the same, a GPIO number passed to
+gpio_to_desc() must have been properly acquired, and usage of the returned GPIO
+descriptor is only possible after the GPIO number has been released.
+

+GPIO Descriptor Driver Interface
+================================
+
+This document serves as a guide for GPIO chip drivers writers. Note that it
+describes the new descriptor-based interface. For a description of the
+deprecated integer-based GPIO interface please refer to gpio-legacy.txt.
+
+Each GPIO controller driver needs to include the following header, which defines
+the structures used to define a GPIO driver:
+
+ #include <linux/gpio/driver.h>
+
+
+Internal Representation of GPIOs
+================================
+
+Inside a GPIO driver, individual GPIOs are identified by their hardware number,
+which is a unique number between 0 and n, n being the number of GPIOs managed by
+the chip. This number is purely internal: the hardware number of a particular
+GPIO descriptor is never made visible outside of the driver.
+
+On top of this internal number, each GPIO also need to have a global number in
+the integer GPIO namespace so that it can be used with the legacy GPIO
+interface. Each chip must thus have a "base" number (which can be automatically
+assigned), and for each GPIO the global number will be (base + hardware number).
+Although the integer representation is considered deprecated, it still has many
+users and thus needs to be maintained.
+
+So for example one platform could use numbers 32-159 for GPIOs, with a
+controller defining 128 GPIOs at a "base" of 32 ; while another platform uses
+numbers 0..63 with one set of GPIO controllers, 64-79 with another type of GPIO
+controller, and on one particular board 80-95 with an FPGA. The numbers need not
+be contiguous; either of those platforms could also use numbers 2000-2063 to
+identify GPIOs in a bank of I2C GPIO expanders.
+
+
+Controller Drivers: gpio_chip
+=============================
+
+In the gpiolib framework each GPIO controller is packaged as a "struct
+gpio_chip" (see linux/gpio/driver.h for its complete definition) with members
+common to each controller of that type:
+
+ - methods to establish GPIO direction
+ - methods used to access GPIO values
+ - method to return the IRQ number associated to a given GPIO
+ - flag saying whether calls to its methods may sleep
+ - optional debugfs dump method (showing extra state like pullup config)
+ - optional base number (will be automatically assigned if omitted)
+ - label for diagnostics and GPIOs mapping using platform data
+
+The code implementing a gpio_chip should support multiple instances of the
+controller, possibly using the driver model. That code will configure each
+gpio_chip and issue gpiochip_add(). Removing a GPIO controller should be rare;
+use gpiochip_remove() when it is unavoidable.
+
+Most often a gpio_chip is part of an instance-specific structure with state not
+exposed by the GPIO interfaces, such as addressing, power management, and more.
+Chips such as codecs will have complex non-GPIO state.
+
+Any debugfs dump method should normally ignore signals which haven't been
+requested as GPIOs. They can use gpiochip_is_requested(), which returns either
+NULL or the label associated with that GPIO when it was requested.
+
+Locking IRQ usage
+-----------------
+Input GPIOs can be used as IRQ signals. When this happens, a driver is requested
+to mark the GPIO as being used as an IRQ:
+
+ int gpiod_lock_as_irq(struct gpio_desc *desc)
+
+This will prevent the use of non-irq related GPIO APIs until the GPIO IRQ lock
+is released:
+
+ void gpiod_unlock_as_irq(struct gpio_desc *desc)

+GPIO Interfaces
+===============
+
+The documents in this directory give detailed instructions on how to access
+GPIOs in drivers, and how to write a driver for a device that provides GPIOs
+itself.
+
+Due to the history of GPIO interfaces in the kernel, there are two different
+ways to obtain and use GPIOs:
+
+ - The descriptor-based interface is the preferred way to manipulate GPIOs,
+and is described by all the files in this directory excepted gpio-legacy.txt.
+ - The legacy integer-based interface which is considered deprecated (but still
+usable for compatibility reasons) is documented in gpio-legacy.txt.
+
+The remainder of this document applies to the new descriptor-based interface.
+gpio-legacy.txt contains the same information applied to the legacy
+integer-based interface.
+
+
+What is a GPIO?
+===============
+
+A "General Purpose Input/Output" (GPIO) is a flexible software-controlled
+digital signal. They are provided from many kinds of chip, and are familiar
+to Linux developers working with embedded and custom hardware. Each GPIO
+represents a bit connected to a particular pin, or "ball" on Ball Grid Array
+(BGA) packages. Board schematics show which external hardware connects to
+which GPIOs. Drivers can be written generically, so that board setup code
+passes such pin configuration data to drivers.
+
+System-on-Chip (SOC) processors heavily rely on GPIOs. In some cases, every
+non-dedicated pin can be configured as a GPIO; and most chips have at least
+several dozen of them. Programmable logic devices (like FPGAs) can easily
+provide GPIOs; multifunction chips like power managers, and audio codecs
+often have a few such pins to help with pin scarcity on SOCs; and there are
+also "GPIO Expander" chips that connect using the I2C or SPI serial buses.
+Most PC southbridges have a few dozen GPIO-capable pins (with only the BIOS
+firmware knowing how they're used).
+
+The exact capabilities of GPIOs vary between systems. Common options:
+
+ - Output values are writable (high=1, low=0). Some chips also have
+ options about how that value is driven, so that for example only one
+ value might be driven, supporting "wire-OR" and similar schemes for the
+ other value (notably, "open drain" signaling).
+
+ - Input values are likewise readable (1, 0). Some chips support readback
+ of pins configured as "output", which is very useful in such "wire-OR"
+ cases (to support bidirectional signaling). GPIO controllers may have
+ input de-glitch/debounce logic, sometimes with software controls.
+
+ - Inputs can often be used as IRQ signals, often edge triggered but
+ sometimes level triggered. Such IRQs may be configurable as system
+ wakeup events, to wake the system from a low power state.
+
+ - Usually a GPIO will be configurable as either input or output, as needed
+ by different product boards; single direction ones exist too.
+
+ - Most GPIOs can be accessed while holding spinlocks, but those accessed
+ through a serial bus normally can't. Some systems support both types.
+
+On a given board each GPIO is used for one specific purpose like monitoring
+MMC/SD card insertion/removal, detecting card write-protect status, driving
+a LED, configuring a transceiver, bit-banging a serial bus, poking a hardware
+watchdog, sensing a switch, and so on.
+
+
+Common GPIO Properties
+======================
+
+These properties are met through all the other documents of the GPIO interface
+and it is useful to understand them, especially if you need to define GPIO
+mappings.
+
+Active-High and Active-Low
+--------------------------
+It is natural to assume that a GPIO is "active" when its output signal is 1
+("high"), and inactive when it is 0 ("low"). However in practice the signal of a
+GPIO may be inverted before is reaches its destination, or a device could decide
+to have different conventions about what "active" means. Such decisions should
+be transparent to device drivers, therefore it is possible to define a GPIO as
+being either active-high ("1" means "active", the default) or active-low ("0"
+means "active") so that drivers only need to worry about the logical signal and
+not about what happens at the line level.
+
+Open Drain and Open Source
+--------------------------
+Sometimes shared signals need to use "open drain" (where only the low signal
+level is actually driven), or "open source" (where only the high signal level is
+driven) signaling. That term applies to CMOS transistors; "open collector" is
+used for TTL. A pullup or pulldown resistor causes the high or low signal level.
+This is sometimes called a "wire-AND"; or more practically, from the negative
+logic (low=true) perspective this is a "wire-OR".
+
+One common example of an open drain signal is a shared active-low IRQ line.
+Also, bidirectional data bus signals sometimes use open drain signals.
+
+Some GPIO controllers directly support open drain and open source outputs; many
+don't. When you need open drain signaling but your hardware doesn't directly
+support it, there's a common idiom you can use to emulate it with any GPIO pin
+that can be used as either an input or an output:
+
+ LOW: gpiod_direction_output(gpio, 0) ... this drives the signal and overrides
+ the pullup.
+
+ HIGH: gpiod_direction_input(gpio) ... this turns off the output, so the pullup
+ (or some other device) controls the signal.
+
+The same logic can be applied to emulate open source signaling, by driving the
+high signal and configuring the GPIO as input for low. This open drain/open
+source emulation can be handled transparently by the GPIO framework.
+
+If you are "driving" the signal high but gpiod_get_value(gpio) reports a low
+value (after the appropriate rise time passes), you know some other component is
+driving the shared signal low. That's not necessarily an error. As one common
+example, that's how I2C clocks are stretched: a slave that needs a slower clock
+delays the rising edge of SCK, and the I2C master adjusts its signaling rate
+accordingly.

+GPIO Sysfs Interface for Userspace
+==================================
+
+Platforms which use the "gpiolib" implementors framework may choose to
+configure a sysfs user interface to GPIOs. This is different from the
+debugfs interface, since it provides control over GPIO direction and
+value instead of just showing a gpio state summary. Plus, it could be
+present on production systems without debugging support.
+
+Given appropriate hardware documentation for the system, userspace could
+know for example that GPIO #23 controls the write protect line used to
+protect boot loader segments in flash memory. System upgrade procedures
+may need to temporarily remove that protection, first importing a GPIO,
+then changing its output state, then updating the code before re-enabling
+the write protection. In normal use, GPIO #23 would never be touched,
+and the kernel would have no need to know about it.
+
+Again depending on appropriate hardware documentation, on some systems
+userspace GPIO can be used to determine system configuration data that
+standard kernels won't know about. And for some tasks, simple userspace
+GPIO drivers could be all that the system really needs.
+
+Note that standard kernel drivers exist for common "LEDs and Buttons"
+GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those
+instead of talking directly to the GPIOs; they integrate with kernel
+frameworks better than your userspace code could.
+
+
+Paths in Sysfs
+--------------
+There are three kinds of entry in /sys/class/gpio:
+
+ - Control interfaces used to get userspace control over GPIOs;
+
+ - GPIOs themselves; and
+
+ - GPIO controllers ("gpio_chip" instances).
+
+That's in addition to standard files including the "device" symlink.
+
+The control interfaces are write-only:
+
+ /sys/class/gpio/
+
+ "export" ... Userspace may ask the kernel to export control of
+ a GPIO to userspace by writing its number to this file.
+
+ Example: "echo 19 > export" will create a "gpio19" node
+ for GPIO #19, if that's not requested by kernel code.
+
+ "unexport" ... Reverses the effect of exporting to userspace.
+
+ Example: "echo 19 > unexport" will remove a "gpio19"
+ node exported using the "export" file.
+
+GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
+and have the following read/write attributes:
+
+ /sys/class/gpio/gpioN/
+
+ "direction" ... reads as either "in" or "out". This value may
+ normally be written. Writing as "out" defaults to
+ initializing the value as low. To ensure glitch free
+ operation, values "low" and "high" may be written to
+ configure the GPIO as an output with that initial value.
+
+ Note that this attribute *will not exist* if the kernel
+ doesn't support changing the direction of a GPIO, or
+ it was exported by kernel code that didn't explicitly
+ allow userspace to reconfigure this GPIO's direction.
+
+ "value" ... reads as either 0 (low) or 1 (high). If the GPIO
+ is configured as an output, this value may be written;
+ any nonzero value is treated as high.
+
+ If the pin can be configured as interrupt-generating interrupt
+ and if it has been configured to generate interrupts (see the
+ description of "edge"), you can poll(2) on that file and
+ poll(2) will return whenever the interrupt was triggered. If
+ you use poll(2), set the events POLLPRI and POLLERR. If you
+ use select(2), set the file descriptor in exceptfds. After
+ poll(2) returns, either lseek(2) to the beginning of the sysfs
+ file and read the new value or close the file and re-open it
+ to read the value.
+
+ "edge" ... reads as either "none", "rising", "falling", or
+ "both". Write these strings to select the signal edge(s)
+ that will make poll(2) on the "value" file return.
+
+ This file exists only if the pin can be configured as an
+ interrupt generating input pin.
+
+ "active_low" ... reads as either 0 (false) or 1 (true). Write
+ any nonzero value to invert the value attribute both
+ for reading and writing. Existing and subsequent
+ poll(2) support configuration via the edge attribute
+ for "rising" and "falling" edges will follow this
+ setting.
+
+GPIO controllers have paths like /sys/class/gpio/gpiochip42/ (for the
+controller implementing GPIOs starting at #42) and have the following
+read-only attributes:
+
+ /sys/class/gpio/gpiochipN/
+
+ "base" ... same as N, the first GPIO managed by this chip
+
+ "label" ... provided for diagnostics (not always unique)
+
+ "ngpio" ... how many GPIOs this manges (N to N + ngpio - 1)
+
+Board documentation should in most cases cover what GPIOs are used for
+what purposes. However, those numbers are not always stable; GPIOs on
+a daughtercard might be different depending on the base board being used,
+or other cards in the stack. In such cases, you may need to use the
+gpiochip nodes (possibly in conjunction with schematics) to determine
+the correct GPIO number to use for a given signal.
+
+
+Exporting from Kernel code
+--------------------------
+Kernel code can explicitly manage exports of GPIOs which have already been
+requested using gpio_request():
+
+ /* export the GPIO to userspace */
+ int gpiod_export(struct gpio_desc *desc, bool direction_may_change);
+
+ /* reverse gpio_export() */
+ void gpiod_unexport(struct gpio_desc *desc);
+
+ /* create a sysfs link to an exported GPIO node */
+ int gpiod_export_link(struct device *dev, const char *name,
+ struct gpio_desc *desc);
+
+ /* change the polarity of a GPIO node in sysfs */
+ int gpiod_sysfs_set_active_low(struct gpio_desc *desc, int value);
+
+After a kernel driver requests a GPIO, it may only be made available in
+the sysfs interface by gpiod_export(). The driver can control whether the
+signal direction may change. This helps drivers prevent userspace code
+from accidentally clobbering important system state.
+
+This explicit exporting can help with debugging (by making some kinds
+of experiments easier), or can provide an always-there interface that's
+suitable for documenting as part of a board support package.
+
+After the GPIO has been exported, gpiod_export_link() allows creating
+symlinks from elsewhere in sysfs to the GPIO sysfs node. Drivers can
+use this to provide the interface under their own device in sysfs with
+a descriptive name.
+
+Drivers can use gpiod_sysfs_set_active_low() to hide GPIO line polarity
+differences between boards from user space. Polarity change can be done both
+before and after gpiod_export(), and previously enabled poll(2) support for
+either rising or falling edge will be reconfigured to follow this setting.

+
+ q = ACCESS_ONCE(a);
+ if (ACCESS_ONCE(q)) {
+ ACCESS_ONCE(b) = p;
+ }
+
+Please note that ACCESS_ONCE() is not optional! Without the ACCESS_ONCE(),

+
+ q = a;
+ if (q) {
+ b = p; /* BUG: Compiler can reorder!!! */
+ do_something();
+ } else {
+ b = p; /* BUG: Compiler can reorder!!! */
+ do_something_else();
+ }
+
+into this, which of course defeats the ordering:
+
+ b = p;
+ q = a;
+ if (q)
+ do_something();
+ else
+ do_something_else();
+
+Worse yet, if the compiler is able to prove (say) that the value of
+variable 'a' is always non-zero, it would be well within its rights
+to optimize the original example by eliminating the "if" statement
+as follows:
+
+ q = a;
+ b = p; /* BUG: Compiler can reorder!!! */
+ do_something();
+
+The solution is again ACCESS_ONCE(), which preserves the ordering between
+the load from variable 'a' and the store to variable 'b':
+
+ q = ACCESS_ONCE(a);
+ if (q) {
+ ACCESS_ONCE(b) = p;
+ do_something();
+ } else {
+ ACCESS_ONCE(b) = p;
+ do_something_else();
+ }
+
+You could also use barrier() to prevent the compiler from moving
+the stores to variable 'b', but barrier() would not prevent the
+compiler from proving to itself that a==1 always, so ACCESS_ONCE()
+is also needed.
+
+It is important to note that control dependencies absolutely require a
+a conditional. For example, the following "optimized" version of
+the above example breaks ordering:
+
+ q = ACCESS_ONCE(a);
+ ACCESS_ONCE(b) = p; /* BUG: No ordering vs. load from a!!! */
+ if (q) {
+ /* ACCESS_ONCE(b) = p; -- moved up, BUG!!! */
+ do_something();
+ } else {
+ /* ACCESS_ONCE(b) = p; -- moved up, BUG!!! */
+ do_something_else();
+ }
+
+It is of course legal for the prior load to be part of the conditional,
+for example, as follows:
+
+ if (ACCESS_ONCE(a) > 0) {
+ ACCESS_ONCE(b) = q / 2;
+ do_something();
+ } else {
+ ACCESS_ONCE(b) = q / 3;
+ do_something_else();
+ }
+
+This will again ensure that the load from variable 'a' is ordered before the
+stores to variable 'b'.
+
+In addition, you need to be careful what you do with the local variable 'q',
+otherwise the compiler might be able to guess the value and again remove
+the needed conditional. For example:
+
+ q = ACCESS_ONCE(a);
+ if (q % MAX) {
+ ACCESS_ONCE(b) = p;
+ do_something();
+ } else {
+ ACCESS_ONCE(b) = p;
+ do_something_else();
+ }
+
+If MAX is defined to be 1, then the compiler knows that (q % MAX) is
+equal to zero, in which case the compiler is within its rights to
+transform the above code into the following:
+
+ q = ACCESS_ONCE(a);
+ ACCESS_ONCE(b) = p;
+ do_something_else();
+
+This transformation loses the ordering between the load from variable 'a'
+and the store to variable 'b'. If you are relying on this ordering, you
+should do something like the following:
+
+ q = ACCESS_ONCE(a);
+ BUILD_BUG_ON(MAX <= 1); /* Order load from a with store to b. */
+ if (q % MAX) {
+ ACCESS_ONCE(b) = p;
+ do_something();
+ } else {
+ ACCESS_ONCE(b) = p;
+ do_something_else();
+ }
+
+Finally, control dependencies do -not- provide transitivity. This is
+demonstrated by two related examples:
+
+ CPU 0 CPU 1
+ ===================== =====================
+ r1 = ACCESS_ONCE(x); r2 = ACCESS_ONCE(y);
+ if (r1 >= 0) if (r2 >= 0)
+ ACCESS_ONCE(y) = 1; ACCESS_ONCE(x) = 1;
+
+ assert(!(r1 == 1 && r2 == 1));
+
+The above two-CPU example will never trigger the assert(). However,
+if control dependencies guaranteed transitivity (which they do not),
+then adding the following two CPUs would guarantee a related assertion:
+
+ CPU 2 CPU 3
+ ===================== =====================
+ ACCESS_ONCE(x) = 2; ACCESS_ONCE(y) = 2;
+
+ assert(!(r1 == 2 && r2 == 2 && x == 1 && y == 1)); /* FAILS!!! */
+
+But because control dependencies do -not- provide transitivity, the
+above assertion can fail after the combined four-CPU example completes.
+If you need the four-CPU example to provide ordering, you will need
+smp_mb() between the loads and stores in the CPU 0 and CPU 1 code fragments.
+
+In summary:
+
+ (*) Control dependencies can order prior loads against later stores.
+ However, they do -not- guarantee any other sort of ordering:
+ Not prior loads against later loads, nor prior stores against
+ later anything. If you need these other forms of ordering,
+ use smb_rmb(), smp_wmb(), or, in the case of prior stores and
+ later loads, smp_mb().
+
+ (*) Control dependencies require at least one run-time conditional
+ between the prior load and the subsequent store. If the compiler
+ is able to optimize the conditional away, it will have also
+ optimized away the ordering. Careful use of ACCESS_ONCE() can
+ help to preserve the needed conditional.
+
+ (*) Control dependencies require that the compiler avoid reordering the
+ dependency into nonexistence. Careful use of ACCESS_ONCE() or
+ barrier() can help to preserve your control dependency. Please
+ see the Compiler Barrier section for more information.

-This is a general barrier - lesser varieties of compiler barrier do not exist.
+This is a general barrier -- there are no read-read or write-write variants
+of barrier(). However, ACCESS_ONCE() can be thought of as a weak form
+for barrier() that affects only the specific accesses flagged by the
+ACCESS_ONCE().
-The compiler barrier has no direct effect on the CPU, which may then reorder
-things however it wishes.
+The barrier() function has the following effects:
+
+ (*) Prevents the compiler from reordering accesses following the
+ barrier() to precede any accesses preceding the barrier().
+ One example use for this property is to ease communication between
+ interrupt-handler code and the code that was interrupted.
+
+ (*) Within a loop, forces the compiler to load the variables used
+ in that loop's conditional on each pass through that loop.
+
+The ACCESS_ONCE() function can prevent any number of optimizations that,
+while perfectly safe in single-threaded code, can be fatal in concurrent
+code. Here are some examples of these sorts of optimizations:
+
+ (*) The compiler is within its rights to merge successive loads from
+ the same variable. Such merging can cause the compiler to "optimize"
+ the following code:
+
+ while (tmp = a)
+ do_something_with(tmp);
+
+ into the following code, which, although in some sense legitimate
+ for single-threaded code, is almost certainly not what the developer
+ intended:
+
+ if (tmp = a)
+ for (;;)
+ do_something_with(tmp);
+
+ Use ACCESS_ONCE() to prevent the compiler from doing this to you:
+
+ while (tmp = ACCESS_ONCE(a))
+ do_something_with(tmp);
+
+ (*) The compiler is within its rights to reload a variable, for example,
+ in cases where high register pressure prevents the compiler from
+ keeping all data of interest in registers. The compiler might
+ therefore optimize the variable 'tmp' out of our previous example:
+
+ while (tmp = a)
+ do_something_with(tmp);
+
+ This could result in the following code, which is perfectly safe in
+ single-threaded code, but can be fatal in concurrent code:
+
+ while (a)
+ do_something_with(a);
+
+ For example, the optimized version of this code could result in
+ passing a zero to do_something_with() in the case where the variable
+ a was modified by some other CPU between the "while" statement and
+ the call to do_something_with().
+
+ Again, use ACCESS_ONCE() to prevent the compiler from doing this:
+
+ while (tmp = ACCESS_ONCE(a))
+ do_something_with(tmp);
+
+ Note that if the compiler runs short of registers, it might save
+ tmp onto the stack. The overhead of this saving and later restoring
+ is why compilers reload variables. Doing so is perfectly safe for
+ single-threaded code, so you need to tell the compiler about cases
+ where it is not safe.
+
+ (*) The compiler is within its rights to omit a load entirely if it knows
+ what the value will be. For example, if the compiler can prove that
+ the value of variable 'a' is always zero, it can optimize this code:
+
+ while (tmp = a)
+ do_something_with(tmp);
+
+ Into this:
+
+ do { } while (0);
+
+ This transformation is a win for single-threaded code because it gets
+ rid of a load and a branch. The problem is that the compiler will
+ carry out its proof assuming that the current CPU is the only one
+ updating variable 'a'. If variable 'a' is shared, then the compiler's
+ proof will be erroneous. Use ACCESS_ONCE() to tell the compiler
+ that it doesn't know as much as it thinks it does:
+
+ while (tmp = ACCESS_ONCE(a))
+ do_something_with(tmp);
+
+ But please note that the compiler is also closely watching what you
+ do with the value after the ACCESS_ONCE(). For example, suppose you
+ do the following and MAX is a preprocessor macro with the value 1:
+
+ while ((tmp = ACCESS_ONCE(a)) % MAX)
+ do_something_with(tmp);
+
+ Then the compiler knows that the result of the "%" operator applied
+ to MAX will always be zero, again allowing the compiler to optimize
+ the code into near-nonexistence. (It will still load from the
+ variable 'a'.)
+
+ (*) Similarly, the compiler is within its rights to omit a store entirely
+ if it knows that the variable already has the value being stored.
+ Again, the compiler assumes that the current CPU is the only one
+ storing into the variable, which can cause the compiler to do the
+ wrong thing for shared variables. For example, suppose you have
+ the following:
+
+ a = 0;
+ /* Code that does not store to variable a. */
+ a = 0;
+
+ The compiler sees that the value of variable 'a' is already zero, so
+ it might well omit the second store. This would come as a fatal
+ surprise if some other CPU might have stored to variable 'a' in the
+ meantime.
+
+ Use ACCESS_ONCE() to prevent the compiler from making this sort of
+ wrong guess:
+
+ ACCESS_ONCE(a) = 0;
+ /* Code that does not store to variable a. */
+ ACCESS_ONCE(a) = 0;
+
+ (*) The compiler is within its rights to reorder memory accesses unless
+ you tell it not to. For example, consider the following interaction
+ between process-level code and an interrupt handler:
+
+ void process_level(void)
+ {
+ msg = get_message();
+ flag = true;
+ }
+
+ void interrupt_handler(void)
+ {
+ if (flag)
+ process_message(msg);
+ }
+
+ There is nothing to prevent the the compiler from transforming
+ process_level() to the following, in fact, this might well be a
+ win for single-threaded code:
+
+ void process_level(void)
+ {
+ flag = true;
+ msg = get_message();
+ }
+
+ If the interrupt occurs between these two statement, then
+ interrupt_handler() might be passed a garbled msg. Use ACCESS_ONCE()
+ to prevent this as follows:
+
+ void process_level(void)
+ {
+ ACCESS_ONCE(msg) = get_message();
+ ACCESS_ONCE(flag) = true;
+ }
+
+ void interrupt_handler(void)
+ {
+ if (ACCESS_ONCE(flag))
+ process_message(ACCESS_ONCE(msg));
+ }
+
+ Note that the ACCESS_ONCE() wrappers in interrupt_handler()
+ are needed if this interrupt handler can itself be interrupted
+ by something that also accesses 'flag' and 'msg', for example,
+ a nested interrupt or an NMI. Otherwise, ACCESS_ONCE() is not
+ needed in interrupt_handler() other than for documentation purposes.
+ (Note also that nested interrupts do not typically occur in modern
+ Linux kernels, in fact, if an interrupt handler returns with
+ interrupts enabled, you will get a WARN_ONCE() splat.)
+
+ You should assume that the compiler can move ACCESS_ONCE() past
+ code not containing ACCESS_ONCE(), barrier(), or similar primitives.
+
+ This effect could also be achieved using barrier(), but ACCESS_ONCE()
+ is more selective: With ACCESS_ONCE(), the compiler need only forget
+ the contents of the indicated memory locations, while with barrier()
+ the compiler must discard the value of all memory locations that
+ it has currented cached in any machine registers. Of course,
+ the compiler must also respect the order in which the ACCESS_ONCE()s
+ occur, though the CPU of course need not do so.
+
+ (*) The compiler is within its rights to invent stores to a variable,
+ as in the following example:
+
+ if (a)
+ b = a;
+ else
+ b = 42;
+
+ The compiler might save a branch by optimizing this as follows:
+
+ b = 42;
+ if (a)
+ b = a;
+
+ In single-threaded code, this is not only safe, but also saves
+ a branch. Unfortunately, in concurrent code, this optimization
+ could cause some other CPU to see a spurious value of 42 -- even
+ if variable 'a' was never zero -- when loading variable 'b'.
+ Use ACCESS_ONCE() to prevent this as follows:
+
+ if (a)
+ ACCESS_ONCE(b) = a;
+ else
+ ACCESS_ONCE(b) = 42;
+
+ The compiler can also invent loads. These are usually less
+ damaging, but they can result in cache-line bouncing and thus in
+ poor performance and scalability. Use ACCESS_ONCE() to prevent
+ invented loads.
+
+ (*) For aligned memory locations whose size allows them to be accessed
+ with a single memory-reference instruction, prevents "load tearing"
+ and "store tearing," in which a single large access is replaced by
+ multiple smaller accesses. For example, given an architecture having
+ 16-bit store instructions with 7-bit immediate fields, the compiler
+ might be tempted to use two 16-bit store-immediate instructions to
+ implement the following 32-bit store:
+
+ p = 0x00010002;
+
+ Please note that GCC really does use this sort of optimization,
+ which is not surprising given that it would likely take more
+ than two instructions to build the constant and then store it.
+ This optimization can therefore be a win in single-threaded code.
+ In fact, a recent bug (since fixed) caused GCC to incorrectly use
+ this optimization in a volatile store. In the absence of such bugs,
+ use of ACCESS_ONCE() prevents store tearing in the following example:
+
+ ACCESS_ONCE(p) = 0x00010002;
+
+ Use of packed structures can also result in load and store tearing,
+ as in this example:
+
+ struct __attribute__((__packed__)) foo {
+ short a;
+ int b;
+ short c;
+ };
+ struct foo foo1, foo2;
+ ...
+
+ foo2.a = foo1.a;
+ foo2.b = foo1.b;
+ foo2.c = foo1.c;
+
+ Because there are no ACCESS_ONCE() wrappers and no volatile markings,
+ the compiler would be well within its rights to implement these three
+ assignment statements as a pair of 32-bit loads followed by a pair
+ of 32-bit stores. This would result in load tearing on 'foo1.b'
+ and store tearing on 'foo2.b'. ACCESS_ONCE() again prevents tearing
+ in this example:
+
+ foo2.a = foo1.a;
+ ACCESS_ONCE(foo2.b) = ACCESS_ONCE(foo1.b);
+ foo2.c = foo1.c;
+
+All that aside, it is never necessary to use ACCESS_ONCE() on a variable
+that has been marked volatile. For example, because 'jiffies' is marked
+volatile, it is never necessary to say ACCESS_ONCE(jiffies). The reason
+for this is that ACCESS_ONCE() is implemented as a volatile cast, which
+has no effect when its argument is already marked volatile.
+
+Please note that these compiler barriers have no direct effect on the CPU,
+which may then reorder things however it wishes.

+INTER-CPU ACQUIRING BARRIER EFFECTS

On SMP systems locking primitives give a more substantial form of barrier: one
that does affect memory access ordering on other CPUs, within the context of
conflict on any particular lock.
-LOCKS VS MEMORY ACCESSES
-------------------------
+ACQUIRES VS MEMORY ACCESSES
+---------------------------
Consider the following: the system has a pair of spinlocks (M) and (Q), and
three CPUs; then should the following sequence of events occur:
CPU 1 CPU 2
=============================== ===============================
- *A = a; *E = e;
- LOCK M LOCK Q
- *B = b; *F = f;
- *C = c; *G = g;
- UNLOCK M UNLOCK Q
- *D = d; *H = h;

+ ACCESS_ONCE(*C) = c; ACCESS_ONCE(*G) = g;
+ RELEASE M RELEASE Q
+ ACCESS_ONCE(*D) = d; ACCESS_ONCE(*H) = h;
Then there is no guarantee as to what order CPU 3 will see the accesses to *A
through *H occur in, other than the constraints imposed by the separate locks
on the separate CPUs. It might, for example, see:
- *E, LOCK M, LOCK Q, *G, *C, *F, *A, *B, UNLOCK Q, *D, *H, UNLOCK M
+ *E, ACQUIRE M, ACQUIRE Q, *G, *C, *F, *A, *B, RELEASE Q, *D, *H, RELEASE M
But it won't see any of:
- *B, *C or *D preceding LOCK M
- *A, *B or *C following UNLOCK M
- *F, *G or *H preceding LOCK Q
- *E, *F or *G following UNLOCK Q
+ *B, *C or *D preceding ACQUIRE M
+ *A, *B or *C following RELEASE M

+ *E, *F or *G following RELEASE Q

- LOCK M [1]
- *B = b;
- *C = c;
- UNLOCK M [1]
- *D = d; *E = e;

+ ACCESS_ONCE(*D) = d; ACCESS_ONCE(*E) = e;

+ smp_mb__after_unlock_lock();
+ ACCESS_ONCE(*F) = f;
+ ACCESS_ONCE(*G) = g;
+ RELEASE M [2]
+ ACCESS_ONCE(*H) = h;
CPU 3 might see:
- *E, LOCK M [1], *C, *B, *A, UNLOCK M [1],
- LOCK M [2], *H, *F, *G, UNLOCK M [2], *D
+ *E, ACQUIRE M [1], *C, *B, *A, RELEASE M [1],
+ ACQUIRE M [2], *H, *F, *G, RELEASE M [2], *D
But assuming CPU 1 gets the lock first, CPU 3 won't see any of:
- *B, *C, *D, *F, *G or *H preceding LOCK M [1]
- *A, *B or *C following UNLOCK M [1]
- *F, *G or *H preceding LOCK M [2]

+ KERNEL MODULE SIGNING FACILITY
+ ==============================
+
+CONTENTS
+
+ - Overview.
+ - Configuring module signing.
+ - Generating signing keys.
+ - Public keys in the kernel.
+ - Manually signing modules.
+ - Signed modules and stripping.
+ - Loading signed modules.
+ - Non-valid signatures and unsigned modules.
+ - Administering/protecting the private key.
+
+
+========
+OVERVIEW
+========
+
+The kernel module signing facility cryptographically signs modules during
+installation and then checks the signature upon loading the module. This
+allows increased kernel security by disallowing the loading of unsigned modules
+or modules signed with an invalid key. Module signing increases security by
+making it harder to load a malicious module into the kernel. The module
+signature checking is done by the kernel so that it is not necessary to have
+trusted userspace bits.
+
+This facility uses X.509 ITU-T standard certificates to encode the public keys
+involved. The signatures are not themselves encoded in any industrial standard
+type. The facility currently only supports the RSA public key encryption
+standard (though it is pluggable and permits others to be used). The possible
+hash algorithms that can be used are SHA-1, SHA-224, SHA-256, SHA-384, and
+SHA-512 (the algorithm is selected by data in the signature).
+
+
+==========================
+CONFIGURING MODULE SIGNING
+==========================
+
+The module signing facility is enabled by going to the "Enable Loadable Module
+Support" section of the kernel configuration and turning on
+
+ CONFIG_MODULE_SIG "Module signature verification"
+
+This has a number of options available:
+
+ (1) "Require modules to be validly signed" (CONFIG_MODULE_SIG_FORCE)
+
+ This specifies how the kernel should deal with a module that has a
+ signature for which the key is not known or a module that is unsigned.
+
+ If this is off (ie. "permissive"), then modules for which the key is not
+ available and modules that are unsigned are permitted, but the kernel will
+ be marked as being tainted.
+
+ If this is on (ie. "restrictive"), only modules that have a valid
+ signature that can be verified by a public key in the kernel's possession
+ will be loaded. All other modules will generate an error.
+
+ Irrespective of the setting here, if the module has a signature block that
+ cannot be parsed, it will be rejected out of hand.
+
+
+ (2) "Automatically sign all modules" (CONFIG_MODULE_SIG_ALL)
+
+ If this is on then modules will be automatically signed during the
+ modules_install phase of a build. If this is off, then the modules must
+ be signed manually using:
+
+ scripts/sign-file
+
+
+ (3) "Which hash algorithm should modules be signed with?"
+
+ This presents a choice of which hash algorithm the installation phase will
+ sign the modules with:
+
+ CONFIG_SIG_SHA1 "Sign modules with SHA-1"
+ CONFIG_SIG_SHA224 "Sign modules with SHA-224"
+ CONFIG_SIG_SHA256 "Sign modules with SHA-256"
+ CONFIG_SIG_SHA384 "Sign modules with SHA-384"
+ CONFIG_SIG_SHA512 "Sign modules with SHA-512"
+
+ The algorithm selected here will also be built into the kernel (rather
+ than being a module) so that modules signed with that algorithm can have
+ their signatures checked without causing a dependency loop.
+
+
+=======================
+GENERATING SIGNING KEYS
+=======================
+
+Cryptographic keypairs are required to generate and check signatures. A
+private key is used to generate a signature and the corresponding public key is
+used to check it. The private key is only needed during the build, after which
+it can be deleted or stored securely. The public key gets built into the
+kernel so that it can be used to check the signatures as the modules are
+loaded.
+
+Under normal conditions, the kernel build will automatically generate a new
+keypair using openssl if one does not exist in the files:
+
+ signing_key.priv
+ signing_key.x509
+
+during the building of vmlinux (the public part of the key needs to be built
+into vmlinux) using parameters in the:
+
+ x509.genkey
+
+file (which is also generated if it does not already exist).
+
+It is strongly recommended that you provide your own x509.genkey file.
+
+Most notably, in the x509.genkey file, the req_distinguished_name section
+should be altered from the default:
+
+ [ req_distinguished_name ]
+ O = Magrathea
+ CN = Glacier signing key
+ emailAddress = slartibartfast@magrathea.h2g2
+
+The generated RSA key size can also be set with:
+
+ [ req ]
+ default_bits = 4096
+
+
+It is also possible to manually generate the key private/public files using the
+x509.genkey key generation configuration file in the root node of the Linux
+kernel sources tree and the openssl command. The following is an example to
+generate the public/private key files:
+
+ openssl req -new -nodes -utf8 -sha256 -days 36500 -batch -x509 \
+ -config x509.genkey -outform DER -out signing_key.x509 \
+ -keyout signing_key.priv
+
+
+=========================
+PUBLIC KEYS IN THE KERNEL
+=========================
+
+The kernel contains a ring of public keys that can be viewed by root. They're
+in a keyring called ".system_keyring" that can be seen by:
+
+ [root@deneb ~]# cat /proc/keys
+ ...
+ 223c7853 I------ 1 perm 1f030000 0 0 keyring .system_keyring: 1
+ 302d2d52 I------ 1 perm 1f010000 0 0 asymmetri Fedora kernel signing key: d69a84e6bce3d216b979e9505b3e3ef9a7118079: X509.RSA a7118079 []
+ ...
+
+Beyond the public key generated specifically for module signing, any file
+placed in the kernel source root directory or the kernel build root directory
+whose name is suffixed with ".x509" will be assumed to be an X.509 public key
+and will be added to the keyring.
+
+Further, the architecture code may take public keys from a hardware store and
+add those in also (e.g. from the UEFI key database).
+
+Finally, it is possible to add additional public keys by doing:
+
+ keyctl padd asymmetric "" [.system_keyring-ID] <[key-file]
+
+e.g.:
+
+ keyctl padd asymmetric "" 0x223c7853 <my_public_key.x509
+
+Note, however, that the kernel will only permit keys to be added to
+.system_keyring _if_ the new key's X.509 wrapper is validly signed by a key
+that is already resident in the .system_keyring at the time the key was added.
+
+
+=========================
+MANUALLY SIGNING MODULES
+=========================
+
+To manually sign a module, use the scripts/sign-file tool available in
+the Linux kernel source tree. The script requires 4 arguments:
+
+ 1. The hash algorithm (e.g., sha256)
+ 2. The private key filename
+ 3. The public key filename
+ 4. The kernel module to be signed
+
+The following is an example to sign a kernel module:
+
+ scripts/sign-file sha512 kernel-signkey.priv \
+ kernel-signkey.x509 module.ko
+
+The hash algorithm used does not have to match the one configured, but if it
+doesn't, you should make sure that hash algorithm is either built into the
+kernel or can be loaded without requiring itself.
+
+
+============================
+SIGNED MODULES AND STRIPPING
+============================
+
+A signed module has a digital signature simply appended at the end. The string
+"~Module signature appended~." at the end of the module's file confirms that a
+signature is present but it does not confirm that the signature is valid!
+
+Signed modules are BRITTLE as the signature is outside of the defined ELF
+container. Thus they MAY NOT be stripped once the signature is computed and
+attached. Note the entire module is the signed payload, including any and all
+debug information present at the time of signing.
+
+
+======================
+LOADING SIGNED MODULES
+======================
+
+Modules are loaded with insmod, modprobe, init_module() or finit_module(),
+exactly as for unsigned modules as no processing is done in userspace. The
+signature checking is all done within the kernel.
+
+
+=========================================
+NON-VALID SIGNATURES AND UNSIGNED MODULES
+=========================================
+
+If CONFIG_MODULE_SIG_FORCE is enabled or enforcemodulesig=1 is supplied on
+the kernel command line, the kernel will only load validly signed modules
+for which it has a public key. Otherwise, it will also load modules that are
+unsigned. Any module for which the kernel has a key, but which proves to have
+a signature mismatch will not be permitted to load.
+
+Any module that has an unparseable signature will be rejected.
+
+
+=========================================
+ADMINISTERING/PROTECTING THE PRIVATE KEY
+=========================================
+
+Since the private key is used to sign modules, viruses and malware could use
+the private key to sign modules and compromise the operating system. The
+private key must be either destroyed or moved to a secure location and not kept
+in the root node of the kernel source tree.

- bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
- help
- This option turns on the -fstack-protector GCC feature. This
- feature puts, at the beginning of functions, a canary value on
- the stack just before the return address, and validates
- the value just before actually returning. Stack based buffer
- overflows (that need to overwrite this return address) now also
- overwrite the canary, which gets detected and the attack is then
- neutralized via a kernel panic.
- This feature requires gcc version 4.2 or above.

- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier. All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads. This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies. See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * b = 2;
- * memory_barrier();
- * p = &b; q = p;
- * read_barrier_depends();
- * d = *q;
- * </programlisting>
- *
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends(). However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * a = 2;
- * memory_barrier();
- * b = 3; y = b;
- * read_barrier_depends();
- * x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b". Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
- * in cases like this where there are no data dependencies.

+ depends on M68KCLASSIC
+ help
+ kexec is a system call that implements the ability to shutdown your
+ current kernel, and to start another kernel. It is like a reboot
+ but it is independent of the system firmware. And like a reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does not
+ initially work for you. As of this writing the exact hardware
+ interface is strongly in flux, so no good recommendation can be

-** Added bi_atari part of the machine dependent union bi_un; for now it
-** contains just a model field to distinguish between TT and Falcon.
-** 26/7/96 Roman Zippel:
-** Renamed to setup.h; added some useful macros to allow gcc some
-** optimizations if possible.
-** 5/10/96 Geert Uytterhoeven:
-** Redesign of the boot information structure; renamed to bootinfo.h again
-** 27/11/96 Geert Uytterhoeven:
-** Backwards compatibility with bootinfo interface version 1.0

- This option turns on the -fstack-protector GCC feature. This

- the stack just before the return address, and validates

-** This is simply the barrier() macro from linux/kernel.h but when serial.c
-** uses tqueue.h uses smp_mb() defined using barrier(), linux/kernel.h
-** hasn't yet been included yet so it fails, thus repeating the macro here.
-**
-** PA-RISC architecture allows for weakly ordered memory accesses although
-** none of the processors use it. There is a strong ordered bit that is
-** set in the O-bit of the page directory entry. Operating systems that
-** can not tolerate out of order accesses should set this bit when mapping
-** pages. The O-bit of the PSW should also be set to 1 (I don't believe any
-** of the processor implemented the PSW O-bit). The PCX-W ERS states that
-** the TLB O-bit is not implemented so the page directory does not need to
-** have the O-bit set when mapping pages (section 3.1). This section also
-** states that the PSW Y, Z, G, and O bits are not implemented.
-** So it looks like nothing needs to be done for parisc-linux (yet).
-** (thanks to chada for the above comment -ggg)

-** The __asm__ op below simple prevents gcc/ld from reordering

- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier. All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads. This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies. See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * b = 2;
- * memory_barrier();
- * p = &b; q = p;
- * read_barrier_depends();
- * d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends(). However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * a = 2;
- * memory_barrier();
- * b = 3; y = b;
- * read_barrier_depends();
- * x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b". Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
- * in cases like this where there are no data dependencies.

+ * 1.0 16 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Initial release.
+ * 1.01 18 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Added read() support + cleanups.
+ * 1.02 21 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Added 'device trimming' support. open(O_WRONLY) zeroes
+ * and frees the saved copy of applied microcode.
+ * 1.03 29 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Made to use devfs (/dev/cpu/microcode) + cleanups.
+ * 1.04 06 Jun 2000, Simon Trimmer <simon@veritas.com>
+ * Added misc device support (now uses both devfs and misc).
+ * Added MICROCODE_IOCFREE ioctl to clear memory.
+ * 1.05 09 Jun 2000, Simon Trimmer <simon@veritas.com>
+ * Messages for error cases (non Intel & no suitable microcode).
+ * 1.06 03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
+ * Removed ->release(). Removed exclusive open and status bitmap.
+ * Added microcode_rwsem to serialize read()/write()/ioctl().
+ * Removed global kernel lock usage.
+ * 1.07 07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
+ * Write 0 to 0x8B msr and then cpuid before reading revision,
+ * so that it works even if there were no update done by the
+ * BIOS. Otherwise, reading from 0x8B gives junk (which happened
+ * to be 0 on my machine which is why it worked even when I
+ * disabled update by the BIOS)
+ * Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
+ * 1.08 11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
+ * Tigran Aivazian <tigran@veritas.com>
+ * Intel Pentium 4 processor support and bugfixes.
+ * 1.09 30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
+ * Bugfix for HT (Hyper-Threading) enabled processors
+ * whereby processor resources are shared by all logical processors
+ * in a single CPU package.
+ * 1.10 28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
+ * Tigran Aivazian <tigran@veritas.com>,
+ * Serialize updates as required on HT processors due to
+ * speculative nature of implementation.
+ * 1.11 22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
+ * Fix the panic when writing zero-length microcode chunk.
+ * 1.12 29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
+ * Jun Nakajima <jun.nakajima@intel.com>
+ * Support for the microcode updates in the new format.
+ * 1.13 10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
+ * Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
+ * because we no longer hold a copy of applied microcode
+ * in kernel memory.
+ * 1.14 25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
+ * Fix sigmatch() macro to handle old CPUs with pf == 0.
+ * Thanks to Stuart Swales for pointing out this bug.

+ * Copyright (C) 2013 Google, Inc., Stephane Eranian
+ *
+ * Intel RAPL interface is specified in the IA-32 Manual Vol3b
+ * section 14.7.1 (September 2013)
+ *
+ * RAPL provides more controls than just reporting energy consumption
+ * however here we only expose the 3 energy consumption free running
+ * counters (pp0, pkg, dram).
+ *
+ * Each of those counters increments in a power unit defined by the
+ * RAPL_POWER_UNIT MSR. On SandyBridge, this unit is 1/(2^16) Joules
+ * but it can vary.
+ *
+ * Counter to rapl events mappings:
+ *
+ * pp0 counter: consumption of all physical cores (power plane 0)
+ * event: rapl_energy_cores
+ * perf code: 0x1
+ *
+ * pkg counter: consumption of the whole processor package
+ * event: rapl_energy_pkg
+ * perf code: 0x2
+ *
+ * dram counter: consumption of the dram domain (servers only)
+ * event: rapl_energy_dram
+ * perf code: 0x3
+ *
+ * dram counter: consumption of the builtin-gpu domain (client only)
+ * event: rapl_energy_gpu
+ * perf code: 0x4
+ *
+ * We manage those counters as free running (read-only). They may be
+ * use simultaneously by other tools, such as turbostat.
+ *
+ * The events only support system-wide mode counting. There is no
+ * sampling support because it does not make sense and is not
+ * supported by the RAPL hardware.
+ *
+ * Because we want to avoid floating-point operations in the kernel,
+ * the events are all reported in fixed point arithmetic (32.32).
+ * Tools must adjust the counts to convert them to Watts using
+ * the duration of the measurement. Tools may use a function such as
+ * ldexp(raw_count, -32);

- * 1.0 16 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Initial release.
- * 1.01 18 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Added read() support + cleanups.
- * 1.02 21 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Added 'device trimming' support. open(O_WRONLY) zeroes
- * and frees the saved copy of applied microcode.
- * 1.03 29 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Made to use devfs (/dev/cpu/microcode) + cleanups.
- * 1.04 06 Jun 2000, Simon Trimmer <simon@veritas.com>
- * Added misc device support (now uses both devfs and misc).
- * Added MICROCODE_IOCFREE ioctl to clear memory.
- * 1.05 09 Jun 2000, Simon Trimmer <simon@veritas.com>
- * Messages for error cases (non Intel & no suitable microcode).
- * 1.06 03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
- * Removed ->release(). Removed exclusive open and status bitmap.
- * Added microcode_rwsem to serialize read()/write()/ioctl().
- * Removed global kernel lock usage.
- * 1.07 07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
- * Write 0 to 0x8B msr and then cpuid before reading revision,
- * so that it works even if there were no update done by the
- * BIOS. Otherwise, reading from 0x8B gives junk (which happened
- * to be 0 on my machine which is why it worked even when I
- * disabled update by the BIOS)
- * Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
- * 1.08 11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
- * Tigran Aivazian <tigran@veritas.com>
- * Intel Pentium 4 processor support and bugfixes.
- * 1.09 30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
- * Bugfix for HT (Hyper-Threading) enabled processors
- * whereby processor resources are shared by all logical processors
- * in a single CPU package.
- * 1.10 28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
- * Tigran Aivazian <tigran@veritas.com>,
- * Serialize updates as required on HT processors due to
- * speculative nature of implementation.
- * 1.11 22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
- * Fix the panic when writing zero-length microcode chunk.
- * 1.12 29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
- * Jun Nakajima <jun.nakajima@intel.com>
- * Support for the microcode updates in the new format.
- * 1.13 10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
- * Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
- * because we no longer hold a copy of applied microcode
- * in kernel memory.
- * 1.14 25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
- * Fix sigmatch() macro to handle old CPUs with pf == 0.
- * Thanks to Stuart Swales for pointing out this bug.

+ *
+ * Documentation: Xtensa LX4 Microprocessor Data Book, Section 2.22
+ *
+ * GPIO32 is a standard optional extension to the Xtensa architecture core that
+ * provides preconfigured output and input ports for intra SoC signaling. The
+ * GPIO32 option is implemented as 32bit Tensilica Instruction Extension (TIE)
+ * output state called EXPSTATE, and 32bit input wire called IMPWIRE. This
+ * driver treats input and output states as two distinct devices.
+ *
+ * Access to GPIO32 specific instructions is controlled by the CPENABLE
+ * (Coprocessor Enable Bits) register. By default Xtensa Linux startup code
+ * disables access to all coprocessors. This driver sets the CPENABLE bit
+ * corresponding to GPIO32 before any GPIO32 specific instruction, and restores
+ * CPENABLE state after that.
+ *
+ * This driver is currently incompatible with SMP. The GPIO32 extension is not
+ * guaranteed to be available in all cores. Moreover, each core controls a
+ * different set of IO wires. A theoretical SMP aware version of this driver
+ * would need to have a per core workqueue to do the actual GPIO manipulation.

+ * This i2c core has a lot of interrupts, namely 8. We use their chaining as
+ * some kind of state machine.
+ *
+ * 1) The main xfer routine kicks off a transmission by putting the start bit
+ * (or repeated start) on the bus and enabling the transmit interrupt (TIE)
+ * since we need to send the slave address + RW bit in every case.
+ *
+ * 2) TIE sends slave address + RW bit and selects how to continue.
+ *
+ * 3a) Write case: We keep utilizing TIE as long as we have data to send. If we
+ * are done, we switch over to the transmission done interrupt (TEIE) and mark
+ * the message as completed (includes sending STOP) there.
+ *
+ * 3b) Read case: We switch over to receive interrupt (RIE). One dummy read is
+ * needed to start clocking, then we keep receiving until we are done. Note
+ * that we use the RDRFS mode all the time, i.e. we ACK/NACK every byte by
+ * writing to the ACKBT bit. I tried using the RDRFS mode only at the end of a
+ * message to create the final NACK as sketched in the datasheet. This caused
+ * some subtle races (when byte n was processed and byte n+1 was already
+ * waiting), though, and I started with the safe approach.
+ *
+ * 4) If we got a NACK somewhere, we flag the error and stop the transmission
+ * via NAKIE.
+ *
+ * Also check the comments in the interrupt routines for some gory details.

+ * Error-handling in case of card malfunction
+ * ------------------------------------------
+ *
+ * If the card is detected to be defective the outside environment
+ * will cause the PCI layer to call deinit (the cleanup function for
+ * probe). This is the same effect like doing a unbind/bind operation
+ * on the card.
+ *
+ * The genwqe card driver implements a health checking thread which
+ * verifies the card function. If this detects a problem the cards
+ * device is being shutdown and restarted again, along with a reset of
+ * the card and queue.
+ *
+ * All functions accessing the card device return either -EIO or -ENODEV
+ * code to indicate the malfunction to the user. The user has to close
+ * the file descriptor and open a new one, once the card becomes
+ * available again.
+ *
+ * If the open file descriptor is setup to receive SIGIO, the signal is
+ * genereated for the application which has to provide a handler to
+ * react on it. If the application does not close the open
+ * file descriptor a SIGKILL is send to enforce freeing the cards
+ * resources.
+ *
+ * I did not find a different way to prevent kernel problems due to
+ * reference counters for the cards character devices getting out of
+ * sync. The character device deallocation does not block, even if
+ * there is still an open file descriptor pending. If this pending
+ * descriptor is closed, the data structures used by the character
+ * device is reinstantiated, which will lead to the reference counter
+ * dropping below the allowed values.
+ *
+ * Card recovery
+ * -------------
+ *
+ * To test the internal driver recovery the following command can be used:
+ * sudo sh -c 'echo 0xfffff > /sys/class/genwqe/genwqe0_card/err_inject'

-Driver: pcmmio
-Description: A driver for the PCM-MIO multifunction board
-Devices: [Winsystems] PCM-MIO (pcmmio)
-Author: Calin Culianu <calin@ajvar.org>
-Updated: Wed, May 16 2007 16:21:10 -0500
-Status: works
-
-A driver for the relatively new PCM-MIO multifunction board from
-Winsystems. This board is a PC-104 based I/O board. It contains
-four subdevices:
- subdevice 0 - 16 channels of 16-bit AI
- subdevice 1 - 8 channels of 16-bit AO
- subdevice 2 - first 24 channels of the 48 channel of DIO
- (with edge-triggered interrupt support)
- subdevice 3 - last 24 channels of the 48 channel DIO
- (no interrupt support for this bank of channels)
-
- Some notes:
-
- Synchronous reads and writes are the only things implemented for AI and AO,
- even though the hardware itself can do streaming acquisition, etc. Anyone
- want to add asynchronous I/O for AI/AO as a feature? Be my guest...
-
- Asynchronous I/O for the DIO subdevices *is* implemented, however! They are
- basically edge-triggered interrupts for any configuration of the first
- 24 DIO-lines.
-
- Also note that this interrupt support is untested.
-
- A few words about edge-detection IRQ support (commands on DIO):
-
- * To use edge-detection IRQ support for the DIO subdevice, pass the IRQ
- of the board to the comedi_config command. The board IRQ is not jumpered
- but rather configured through software, so any IRQ from 1-15 is OK.
-
- * Due to the genericity of the comedi API, you need to create a special
- comedi_command in order to use edge-triggered interrupts for DIO.
-
- * Use comedi_commands with TRIG_NOW. Your callback will be called each
- time an edge is detected on the specified DIO line(s), and the data
- values will be two sample_t's, which should be concatenated to form
- one 32-bit unsigned int. This value is the mask of channels that had
- edges detected from your channel list. Note that the bits positions
- in the mask correspond to positions in your chanlist when you
- specified the command and *not* channel id's!
-
- * To set the polarity of the edge-detection interrupts pass a nonzero value
- for either CR_RANGE or CR_AREF for edge-up polarity, or a zero
- value for both CR_RANGE and CR_AREF if you want edge-down polarity.
-
-Configuration Options:
- [0] - I/O port base address
- [1] - IRQ (optional -- for edge-detect interrupt support only,
- leave out if you don't need this feature)

+ * Author: Calin Culianu <calin@ajvar.org>
+ * Updated: Wed, May 16 2007 16:21:10 -0500
+ * Status: works
+ *
+ * A driver for the PCM-MIO multifunction board from Winsystems. This
+ * is a PC-104 based I/O board. It contains four subdevices:
+ *
+ * subdevice 0 - 16 channels of 16-bit AI
+ * subdevice 1 - 8 channels of 16-bit AO
+ * subdevice 2 - first 24 channels of the 48 channel of DIO
+ * (with edge-triggered interrupt support)
+ * subdevice 3 - last 24 channels of the 48 channel DIO
+ * (no interrupt support for this bank of channels)
+ *
+ * Some notes:
+ *
+ * Synchronous reads and writes are the only things implemented for analog
+ * input and output. The hardware itself can do streaming acquisition, etc.
+ *
+ * Asynchronous I/O for the DIO subdevices *is* implemented, however! They
+ * are basically edge-triggered interrupts for any configuration of the
+ * channels in subdevice 2.
+ *
+ * Also note that this interrupt support is untested.
+ *
+ * A few words about edge-detection IRQ support (commands on DIO):
+ *
+ * To use edge-detection IRQ support for the DIO subdevice, pass the IRQ
+ * of the board to the comedi_config command. The board IRQ is not jumpered
+ * but rather configured through software, so any IRQ from 1-15 is OK.
+ *
+ * Due to the genericity of the comedi API, you need to create a special
+ * comedi_command in order to use edge-triggered interrupts for DIO.
+ *
+ * Use comedi_commands with TRIG_NOW. Your callback will be called each
+ * time an edge is detected on the specified DIO line(s), and the data
+ * values will be two sample_t's, which should be concatenated to form
+ * one 32-bit unsigned int. This value is the mask of channels that had
+ * edges detected from your channel list. Note that the bits positions
+ * in the mask correspond to positions in your chanlist when you
+ * specified the command and *not* channel id's!
+ *
+ * To set the polarity of the edge-detection interrupts pass a nonzero value
+ * for either CR_RANGE or CR_AREF for edge-up polarity, or a zero
+ * value for both CR_RANGE and CR_AREF if you want edge-down polarity.
+ *
+ * Configuration Options:
+ * [0] - I/O port base address
+ * [1] - IRQ (optional -- for edge-detect interrupt support only,
+ * leave out if you don't need this feature)

-TODO:
- - Dan Carpenter would like to see some cleanups to the microframe
- scheduler code:
- http://www.mail-archive.com/linux-usb@vger.kernel.org/msg26650.html
-
- - Should merge the NAK holdoff patch from Raspberry Pi
- (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands
- that patch is incomplete, it needs more investigation to see if it
- can be made to work for non-Raspberry Pi platforms that lack the
- special FIQ interrupt that the Pi has. Without this patch, the driver
- has a high interrupt rate (8K/sec).
-
- - The Raspberry Pi platform needs to have support for its FIQ interrupt
- added, to get the same level of functionality as the downstream
- driver. The raspberrypi.org developers have indicated they are
- willing to help with that.
-
- - Some of the default driver parameters (see 'struct dwc2_core_params'
- in core.h) won't work for many platforms. So DT attributes will need
- to be added for some of these. But that can be done as-needed as new
- platforms are added.
-
- - Eventually the driver should be merged with the s3c-hsotg peripheral
- mode driver, so that both modes of operation can be supported with a
- single driver. But I think that can wait till after the driver has
- been moved to mainline.
-
- - After that, OTG support can be added. I'm not sure how much demand
- there is for that, though, so I have that as a low priority.
-
-Please send any patches for this driver to Paul Zimmerman <paulz@synopsys.com>
-and Greg Kroah-Hartman <gregkh@linuxfoundation.org>. And please CC linux-usb
-<linux-usb@vger.kernel.org> too.

-/**
- * struct dwc2_hsotg - Holds the state of the driver, including the non-periodic
- * and periodic schedules
- *
- * @dev: The struct device pointer
- * @regs: Pointer to controller regs
- * @core_params: Parameters that define how the core should be configured
- * @hw_params: Parameters that were autodetected from the
- * hardware registers
- * @op_state: The operational State, during transitions (a_host=>
- * a_peripheral and b_device=>b_host) this may not match
- * the core, but allows the software to determine
- * transitions
- * @queuing_high_bandwidth: True if multiple packets of a high-bandwidth
- * transfer are in process of being queued
- * @srp_success: Stores status of SRP request in the case of a FS PHY
- * with an I2C interface
- * @wq_otg: Workqueue object used for handling of some interrupts
- * @wf_otg: Work object for handling Connector ID Status Change
- * interrupt
- * @wkp_timer: Timer object for handling Wakeup Detected interrupt
- * @lx_state: Lx state of connected device
- * @flags: Flags for handling root port state changes
- * @non_periodic_sched_inactive: Inactive QHs in the non-periodic schedule.
- * Transfers associated with these QHs are not currently
- * assigned to a host channel.
- * @non_periodic_sched_active: Active QHs in the non-periodic schedule.
- * Transfers associated with these QHs are currently
- * assigned to a host channel.
- * @non_periodic_qh_ptr: Pointer to next QH to process in the active
- * non-periodic schedule
- * @periodic_sched_inactive: Inactive QHs in the periodic schedule. This is a
- * list of QHs for periodic transfers that are _not_
- * scheduled for the next frame. Each QH in the list has an
- * interval counter that determines when it needs to be
- * scheduled for execution. This scheduling mechanism
- * allows only a simple calculation for periodic bandwidth
- * used (i.e. must assume that all periodic transfers may
- * need to execute in the same frame). However, it greatly
- * simplifies scheduling and should be sufficient for the
- * vast majority of OTG hosts, which need to connect to a
- * small number of peripherals at one time. Items move from
- * this list to periodic_sched_ready when the QH interval
- * counter is 0 at SOF.
- * @periodic_sched_ready: List of periodic QHs that are ready for execution in
- * the next frame, but have not yet been assigned to host
- * channels. Items move from this list to
- * periodic_sched_assigned as host channels become
- * available during the current frame.
- * @periodic_sched_assigned: List of periodic QHs to be executed in the next
- * frame that are assigned to host channels. Items move
- * from this list to periodic_sched_queued as the
- * transactions for the QH are queued to the DWC_otg
- * controller.
- * @periodic_sched_queued: List of periodic QHs that have been queued for
- * execution. Items move from this list to either
- * periodic_sched_inactive or periodic_sched_ready when the
- * channel associated with the transfer is released. If the
- * interval for the QH is 1, the item moves to
- * periodic_sched_ready because it must be rescheduled for
- * the next frame. Otherwise, the item moves to
- * periodic_sched_inactive.
- * @periodic_usecs: Total bandwidth claimed so far for periodic transfers.
- * This value is in microseconds per (micro)frame. The
- * assumption is that all periodic transfers may occur in
- * the same (micro)frame.
- * @frame_usecs: Internal variable used by the microframe scheduler
- * @frame_number: Frame number read from the core at SOF. The value ranges
- * from 0 to HFNUM_MAX_FRNUM.
- * @periodic_qh_count: Count of periodic QHs, if using several eps. Used for
- * SOF enable/disable.
- * @free_hc_list: Free host channels in the controller. This is a list of
- * struct dwc2_host_chan items.
- * @periodic_channels: Number of host channels assigned to periodic transfers.
- * Currently assuming that there is a dedicated host
- * channel for each periodic transaction and at least one
- * host channel is available for non-periodic transactions.
- * @non_periodic_channels: Number of host channels assigned to non-periodic
- * transfers
- * @available_host_channels Number of host channels available for the microframe
- * scheduler to use
- * @hc_ptr_array: Array of pointers to the host channel descriptors.
- * Allows accessing a host channel descriptor given the
- * host channel number. This is useful in interrupt
- * handlers.
- * @status_buf: Buffer used for data received during the status phase of
- * a control transfer.
- * @status_buf_dma: DMA address for status_buf
- * @start_work: Delayed work for handling host A-cable connection
- * @reset_work: Delayed work for handling a port reset
- * @lock: Spinlock that protects all the driver data structures
- * @priv: Stores a pointer to the struct usb_hcd
- * @otg_port: OTG port number
- * @frame_list: Frame list
- * @frame_list_dma: Frame list DMA address

- Implement NAPI support
- In et131x_tx(), don't return NETDEV_TX_BUSY, just drop the packet with kfree_skb().
- Reduce the number of split lines by careful consideration of variable names etc.
- - Do this in et131x.c:
- struct fbr_lookup *fbr;
- fbr = rx_local->fbr[id];
- Then replace all the instances of "rx_local->fbr[id]" with fbr.

+ * assigned to a host channel.
+ * @non_periodic_qh_ptr: Pointer to next QH to process in the active
+ * non-periodic schedule
+ * @periodic_sched_inactive: Inactive QHs in the periodic schedule. This is a
+ * list of QHs for periodic transfers that are _not_
+ * scheduled for the next frame. Each QH in the list has an
+ * interval counter that determines when it needs to be
+ * scheduled for execution. This scheduling mechanism
+ * allows only a simple calculation for periodic bandwidth
+ * used (i.e. must assume that all periodic transfers may
+ * need to execute in the same frame). However, it greatly
+ * simplifies scheduling and should be sufficient for the
+ * vast majority of OTG hosts, which need to connect to a
+ * small number of peripherals at one time. Items move from
+ * this list to periodic_sched_ready when the QH interval
+ * counter is 0 at SOF.
+ * @periodic_sched_ready: List of periodic QHs that are ready for execution in
+ * the next frame, but have not yet been assigned to host
+ * channels. Items move from this list to
+ * periodic_sched_assigned as host channels become
+ * available during the current frame.
+ * @periodic_sched_assigned: List of periodic QHs to be executed in the next
+ * frame that are assigned to host channels. Items move
+ * from this list to periodic_sched_queued as the
+ * transactions for the QH are queued to the DWC_otg
+ * controller.
+ * @periodic_sched_queued: List of periodic QHs that have been queued for
+ * execution. Items move from this list to either
+ * periodic_sched_inactive or periodic_sched_ready when the
+ * channel associated with the transfer is released. If the
+ * interval for the QH is 1, the item moves to
+ * periodic_sched_ready because it must be rescheduled for
+ * the next frame. Otherwise, the item moves to
+ * periodic_sched_inactive.
+ * @periodic_usecs: Total bandwidth claimed so far for periodic transfers.
+ * This value is in microseconds per (micro)frame. The
+ * assumption is that all periodic transfers may occur in
+ * the same (micro)frame.
+ * @frame_usecs: Internal variable used by the microframe scheduler
+ * @frame_number: Frame number read from the core at SOF. The value ranges
+ * from 0 to HFNUM_MAX_FRNUM.
+ * @periodic_qh_count: Count of periodic QHs, if using several eps. Used for
+ * SOF enable/disable.
+ * @free_hc_list: Free host channels in the controller. This is a list of
+ * struct dwc2_host_chan items.
+ * @periodic_channels: Number of host channels assigned to periodic transfers.
+ * Currently assuming that there is a dedicated host
+ * channel for each periodic transaction and at least one
+ * host channel is available for non-periodic transactions.
+ * @non_periodic_channels: Number of host channels assigned to non-periodic
+ * transfers
+ * @available_host_channels Number of host channels available for the microframe
+ * scheduler to use
+ * @hc_ptr_array: Array of pointers to the host channel descriptors.
+ * Allows accessing a host channel descriptor given the
+ * host channel number. This is useful in interrupt
+ * handlers.
+ * @status_buf: Buffer used for data received during the status phase of
+ * a control transfer.
+ * @status_buf_dma: DMA address for status_buf
+ * @start_work: Delayed work for handling host A-cable connection
+ * @reset_work: Delayed work for handling a port reset
+ * @lock: Spinlock that protects all the driver data structures
+ * @priv: Stores a pointer to the struct usb_hcd
+ * @otg_port: OTG port number

+ * Extended scheduling parameters data structure.
+ *
+ * This is needed because the original struct sched_param can not be
+ * altered without introducing ABI issues with legacy applications
+ * (e.g., in sched_getparam()).
+ *
+ * However, the possibility of specifying more than just a priority for
+ * the tasks may be useful for a wide variety of application fields, e.g.,
+ * multimedia, streaming, automation and control, and many others.
+ *
+ * This variant (sched_attr) is meant at describing a so-called
+ * sporadic time-constrained task. In such model a task is specified by:
+ * - the activation period or minimum instance inter-arrival time;
+ * - the maximum (or average, depending on the actual scheduling
+ * discipline) computation time of all instances, a.k.a. runtime;
+ * - the deadline (relative to the actual activation time) of each
+ * instance.
+ * Very briefly, a periodic (sporadic) task asks for the execution of
+ * some specific computation --which is typically called an instance--
+ * (at most) every period. Moreover, each instance typically lasts no more
+ * than the runtime and must be completed by time instant t equal to
+ * the instance activation time + the deadline.
+ *
+ * This is reflected by the actual fields of the sched_attr structure:
+ *
+ * @size size of the structure, for fwd/bwd compat.
+ *
+ * @sched_policy task's scheduling policy
+ * @sched_flags for customizing the scheduler behaviour
+ * @sched_nice task's nice value (SCHED_NORMAL/BATCH)
+ * @sched_priority task's static priority (SCHED_FIFO/RR)
+ * @sched_deadline representative of the task's deadline
+ * @sched_runtime representative of the task's runtime
+ * @sched_period representative of the task's period
+ *
+ * Given this task model, there are a multiplicity of scheduling algorithms
+ * and policies, that can be used to ensure all the tasks will make their
+ * timing constraints.
+ *
+ * As of now, the SCHED_DEADLINE policy (sched_dl scheduling class) is the
+ * only user of this new interface. More information about the algorithm

+ * DMA addresses or DMA addresses of a scatter gather list which is

+ * will check that against the ATS field definition. Any invalid or

+ * Basic futex operation and ordering guarantees:
+ *
+ * The waiter reads the futex value in user space and calls
+ * futex_wait(). This function computes the hash bucket and acquires
+ * the hash bucket lock. After that it reads the futex user space value
+ * again and verifies that the data has not changed. If it has not changed
+ * it enqueues itself into the hash bucket, releases the hash bucket lock
+ * and schedules.
+ *
+ * The waker side modifies the user space value of the futex and calls
+ * futex_wake(). This function computes the hash bucket and acquires the
+ * hash bucket lock. Then it looks for waiters on that futex in the hash
+ * bucket and wakes them.
+ *
+ * In futex wake up scenarios where no tasks are blocked on a futex, taking
+ * the hb spinlock can be avoided and simply return. In order for this
+ * optimization to work, ordering guarantees must exist so that the waiter
+ * being added to the list is acknowledged when the list is concurrently being
+ * checked by the waker, avoiding scenarios like the following:
+ *
+ * CPU 0 CPU 1
+ * val = *futex;
+ * sys_futex(WAIT, futex, val);
+ * futex_wait(futex, val);
+ * uval = *futex;

+ * if (uval == val)
+ * lock(hash_bucket(futex));
+ * queue();
+ * unlock(hash_bucket(futex));
+ * schedule();
+ *
+ * This would cause the waiter on CPU 0 to wait forever because it
+ * missed the transition of the user space value from val to newval
+ * and the waker did not find the waiter in the hash bucket queue.
+ *
+ * The correct serialization ensures that a waiter either observes
+ * the changed user space value before blocking or is woken by a
+ * concurrent waker:
+ *
+ * CPU 0 CPU 1
+ * val = *futex;
+ * sys_futex(WAIT, futex, val);
+ * futex_wait(futex, val);

-// SCB (DMA from host) to any other SCB. This is useful for AC3 through SPDIF.

+cpupower [ \-c cpulist ] idle\-info [\fIoptions\fP]
+.SH "DESCRIPTION"
+.LP
+The cpupower idle\-set subcommand allows to set cpu idle, also called cpu
+sleep state, specific options offered by the kernel. One example is disabling
+sleep states. This can be handy for power vs performance tuning.
+.SH "OPTIONS"
+.LP
+.TP
+\fB\-d\fR \fB\-\-disable\fR
+Disable a specific processor sleep state.
+.TP
+\fB\-e\fR \fB\-\-enable\fR
+Enable a specific processor sleep state.
+
+.SH "REMARKS"
+.LP
+Cpuidle Governors Policy on Disabling Sleep States
+
+.RS 4
+Depending on the used cpuidle governor, implementing the kernel policy
+how to choose sleep states, subsequent sleep states on this core, might get
+disabled as well.
+
+There are two cpuidle governors ladder and menu. While the ladder
+governor is always available, if CONFIG_CPU_IDLE is selected, the
+menu governor additionally requires CONFIG_NO_HZ.
+
+The behavior and the effect of the disable variable depends on the
+implementation of a particular governor. In the ladder governor, for
+example, it is not coherent, i.e. if one is disabling a light state,
+then all deeper states are disabled as well. Likewise, if one enables a
+deep state but a lighter state still is disabled, then this has no effect.
+.RE
+.LP
+Disabling the Lightest Sleep State may not have any Affect
+
+.RS 4
+If criteria are not met to enter deeper sleep states and the lightest sleep
+state is chosen when idle, the kernel may still enter this sleep state,
+irrespective of whether it is disabled or not. This is also reflected in
+the usage count of the disabled sleep state when using the cpupower idle-info
+command.
+.RE
+.LP
+Selecting specific CPU Cores
+
+.RS 4
+By default processor sleep states of all CPU cores are set. Please refer
+to the cpupower(1) manpage in the \-\-cpu option section how to disable
+C-states of specific cores.

+This document describes one way to create the initrd directory hierarchy
+in order to allow an initrd to be built into your kernel. The trick
+here is to steal the initrd file used on your Linux laptop, Ubuntu in
+this case. There are probably much better ways of doing this.
+
+That said, here are the commands:
+
+------------------------------------------------------------------------
+zcat /initrd.img > /tmp/initrd.img.zcat
+mkdir initrd
+cd initrd
+cpio -id < /tmp/initrd.img.zcat
+------------------------------------------------------------------------
+
+Interestingly enough, if you are running rcutorture, you don't really
+need userspace in many cases. Running without userspace has the
+advantage of allowing you to test your kernel independently of the
+distro in place, the root-filesystem layout, and so on. To make this
+happen, put the following script in the initrd's tree's "/init" file,
+with 0755 mode.
+
+------------------------------------------------------------------------

+
+[ -d /dev ] || mkdir -m 0755 /dev
