+Description: POWERNV CPUFreq driver's frequency throttle stats directory and
+ attributes
+
+ 'cpuX/cpufreq/throttle_stats' directory contains the CPU frequency
+ throttle stat attributes for the chip. The throttle stats of a cpu
+ is common across all the cpus belonging to a chip. Below are the
+ throttle attributes exported in the 'throttle_stats' directory:
+
+ - turbo_stat : This file gives the total number of times the max
+ frequency is throttled to lower frequency in turbo (at and above
+ nominal frequency) range of frequencies.
+
+ - sub_turbo_stat : This file gives the total number of times the
+ max frequency is throttled to lower frequency in sub-turbo(below
+ nominal frequency) range of frequencies.
+
+ - unthrottle : This file gives the total number of times the max
+ frequency is unthrottled after being throttled.
+
+ - powercap : This file gives the total number of times the max
+ frequency is throttled due to 'Power Capping'.
+
+ - overtemp : This file gives the total number of times the max
+ frequency is throttled due to 'CPU Over Temperature'.
+
+ - supply_fault : This file gives the total number of times the
+ max frequency is throttled due to 'Power Supply Failure'.
+
+ - overcurrent : This file gives the total number of times the
+ max frequency is throttled due to 'Overcurrent'.
+
+ - occ_reset : This file gives the total number of times the max
+ frequency is throttled due to 'OCC Reset'.
+
+ The sysfs attributes representing different throttle reasons like
+ powercap, overtemp, supply_fault, overcurrent and occ_reset map to
+ the reasons provided by OCC firmware for throttling the frequency.

+Qualcomm Atheros IPQ4019 TLMM block
+
+This is the Top Level Mode Multiplexor block found on the Qualcomm IPQ8019
+platform, it provides pinctrl, pinmux, pinconf, and gpiolib facilities.
+
+Required properties:
+- compatible: "qcom,ipq4019-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".
+
+The 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-gpio99
+ Supports mux, bias and drive-strength
+
+Valid values for qcom,function are:
+gpio, blsp_uart1, blsp_i2c0, blsp_i2c1, blsp_uart0, blsp_spi1, blsp_spi0
+

+Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
+
+Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
+of these regulators are defined under parent device node.
+Details of regulator properties are defined as child node under
+sub-node "regulators" which is child node of device node.
+
+Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
+for common regulator bindings used by client.
+
+Following are properties of parent node related to regulators.
+
+Optional properties:
+-------------------
+The input supply of regulators are the optional properties on the
+parent device node. The input supply of these regulators are provided
+through following properties:
+in-sd0-supply: Input supply for SD0, INA-SD0 or INB-SD0 pins.
+in-sd1-supply: Input supply for SD1.
+in-sd2-supply: Input supply for SD2.
+in-sd3-supply: Input supply for SD3.
+in-ldo0-1-supply: Input supply for LDO0 and LDO1.
+in-ldo2-supply: Input supply for LDO2.
+in-ldo3-5-supply: Input supply for LDO3 and LDO5
+in-ldo4-6-supply: Input supply for LDO4 and LDO6.
+in-ldo7-8-supply: Input supply for LDO7 and LDO8.
+
+Optional sub nodes for regulators under "regulators" subnode:
+------------------------------------------------------------
+The subnodes name is the name of regulator and it must be one of:
+ sd[0-3], ldo[0-8]
+
+Each sub-node should contain the constraints and initialization
+information for that regulator. The definition for each of these
+nodes is defined using the standard binding for regulators found at
+<Documentation/devicetree/bindings/regulator/regulator.txt>.
+
+Theres are also additional properties for SD/LDOs. These additional properties
+are required to configure FPS configuration parameters for SDs and LDOs.
+Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
+Power Sequence (FPS).
+Following are additional properties:
+
+- maxim,active-fps-source: FPS source for the regulators to get
+ enabled/disabled when system is in
+ active state. Valid values are:
+ - MAX77620_FPS_SRC_0,
+ FPS source is FPS0.
+ - MAX77620_FPS_SRC_1,
+ FPS source is FPS1
+ - MAX77620_FPS_SRC_2 and
+ FPS source is FPS2
+ - MAX77620_FPS_SRC_NONE.
+ Regulator is not controlled
+ by FPS events and it gets
+ enabled/disabled by register
+ access.
+ Absence of this property will leave
+ the FPS configuration register for that
+ regulator to default configuration.
+
+- maxim,active-fps-power-up-slot: Sequencing event slot number on which
+ the regulator get enabled when
+ master FPS input event set to HIGH.
+ Valid values are 0 to 7.
+ This is applicable if FPS source is
+ selected as FPS0, FPS1 or FPS2.
+
+- maxim,active-fps-power-down-slot: Sequencing event slot number on which
+ the regulator get disabled when master
+ FPS input event set to LOW.
+ Valid values are 0 to 7.
+ This is applicable if FPS source is
+ selected as FPS0, FPS1 or FPS2.
+
+- maxim,suspend-fps-source: This is same as property
+ "maxim,active-fps-source" but value
+ get configured when system enters in
+ to suspend state.
+
+- maxim,suspend-fps-power-up-slot: This is same as property
+ "maxim,active-fps-power-up-slot" but
+ this value get configured into FPS
+ configuration register when system
+ enters into suspend.
+ This is applicable if suspend state
+ FPS source is selected as FPS0, FPS1 or

+* ICP DAS LP-8841 SPI Controller for RTC
+
+ICP DAS LP-8841 contains a DS-1302 RTC. RTC is connected to an IO
+memory register, which acts as an SPI master device.
+
+The device uses the standard MicroWire half-duplex transfer timing.
+Master output is set on low clock and sensed by the RTC on the rising
+edge. Master input is set by the RTC on the trailing edge and is sensed
+by the master on low clock.
+
+Required properties:
+
+- #address-cells: should be 1
+
+- #size-cells: should be 0
+
+- compatible: should be "icpdas,lp8841-spi-rtc"
+
+- reg: should provide IO memory address
+
+Requirements to SPI slave nodes:
+
+- There can be only one slave device.
+
+- The spi slave node should claim the following flags which are
+ required by the spi controller.
+
+ - spi-3wire: The master itself has only 3 wire. It cannor work in
+ full duplex mode.
+
+ - spi-cs-high: DS-1302 has active high chip select line. The master
+ doesn't support active low.
+
+ - spi-lsb-first: DS-1302 requires least significant bit first
+ transfers. The master only support this type of bit ordering.
+
+
+Example:
+

+ #address-cells = <1>;
+ #size-cells = <0>;

+Description
+-----------
+
+LTC2990 is a Quad I2C Voltage, Current and Temperature Monitor.
+The chip's inputs can measure 4 voltages, or two inputs together (1+2 and 3+4)
+can be combined to measure a differential voltage, which is typically used to
+measure current through a series resistor, or a temperature.
+
+This driver currently uses the 2x differential mode only. In order to support
+other modes, the driver will need to be expanded.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+
+Sysfs attributes
+----------------
+
+The "curr*_input" measurements actually report the voltage drop across the
+input pins in microvolts. This is equivalent to the current through a 1mOhm
+sense resistor. Divide the reported value by the actual sense resistor value
+in mOhm to get the actual value.
+
+in0_input Voltage at Vcc pin in millivolt (range 2.5V to 5V)
+temp1_input Internal chip temperature in millidegrees Celcius
+curr1_input Current in mA across v1-v2 assuming a 1mOhm sense resistor.
+curr2_input Current in mA across v3-v4 assuming a 1mOhm sense resistor.

+Kernel driver nsa320_hwmon
+==========================
+
+Supported chips:
+ * Holtek HT46R065 microcontroller with onboard firmware that configures

+ Prefix: 'nsa320'
+ Addresses scanned: none
+ Datasheet: Not available, driver was reverse engineered based upon the

+
+Author:
+ Adam Baker <linux@baker-net.org.uk>
+
+Description
+-----------
+
+This chip is known to be used in the Zyxel NSA320 and NSA325 NAS Units and
+also in some variants of the NSA310 but the driver has only been tested
+on the NSA320. In all of these devices it is connected to the same 3 GPIO
+lines which are used to provide chip select, clock and data lines. The
+interface behaves similarly to SPI but at much lower speeds than are normally
+used for SPI.
+
+Following each chip select pulse the chip will generate a single 32 bit word
+that contains 0x55 as a marker to indicate that data is being read correctly,
+followed by an 8 bit fan speed in 100s of RPM and a 16 bit temperature in
+tenths of a degree.
+
+
+sysfs-Interface
+---------------
+
+temp1_input - temperature input
+fan1_input - fan speed
+
+Notes
+-----
+
+The access timings used in the driver are the same as used in the Zyxel
+provided kernel. Testing has shown that if the delay between chip select and
+the first clock pulse is reduced from 100 ms to just under 10ms then the chip
+will not produce any output. If the duration of either phase of the clock
+is reduced from 100 us to less than 15 us then data pulses are likely to be
+read twice corrupting the output. The above analysis is based upon a sample
+of one unit but suggests that the Zyxel provided delay values include a
+reasonable tolerance.
+
+The driver incorporates a limit that it will not check for updated values
+faster than once a second. This is because the hardware takes a relatively long
+time to read the data from the device and when it does it reads both temp and
+fan speed. As the most likely case for two accesses in quick succession is
+to read both of these values avoiding a second read delay is desirable.

5.2. How to online memory
------------
-Even if the memory is hot-added, it is not at ready-to-use state.
-For using newly added memory, you have to "online" the memory block.
+When the memory is hot-added, the kernel decides whether or not to "online"
+it according to the policy which can be read from "auto_online_blocks" file:
-For onlining, you have to write "online" to the memory block's state file as:
+% cat /sys/devices/system/memory/auto_online_blocks
+
+The default is "offline" which means the newly added memory is not in a
+ready-to-use state and you have to "online" the newly added memory blocks
+manually. Automatic onlining can be requested by writing "online" to
+"auto_online_blocks" file:
+
+% echo online > /sys/devices/system/memory/auto_online_blocks
+
+This sets a global policy and impacts all memory blocks that will subsequently
+be hotplugged. Currently offline blocks keep their state. It is possible, under
+certain circumstances, that some memory blocks will be added but will fail to
+online. User space tools can check their "state" files
+(/sys/devices/system/memory/memoryXXX/state) and try to online them manually.
+
+If the automatic onlining wasn't requested, failed, or some memory block was
+offlined it is possible to change the individual block's state by writing to the
+"state" file:
% echo online > /sys/devices/system/memory/memoryXXX/state

+4.97 KVM_CAP_PPC_MULTITCE
+
+Capability: KVM_CAP_PPC_MULTITCE
+Architectures: ppc
+Type: vm
+
+This capability means the kernel is capable of handling hypercalls
+H_PUT_TCE_INDIRECT and H_STUFF_TCE without passing those into the user
+space. This significantly accelerates DMA operations for PPC KVM guests.
+User space should expect that its handlers for these hypercalls
+are not going to be called if user space previously registered LIOBN
+in KVM (via KVM_CREATE_SPAPR_TCE or similar calls).
+
+In order to enable H_PUT_TCE_INDIRECT and H_STUFF_TCE use in the guest,
+user space might have to advertise it for the guest. For example,
+IBM pSeries (sPAPR) guest starts using them if "hcall-multi-tce" is
+present in the "ibm,hypertas-functions" device-tree property.
+
+The hypercalls mentioned above may or may not be processed successfully
+in the kernel based fast path. If they can not be handled by the kernel,
+they will get passed on to user space. So user space still has to have
+an implementation for these despite the in kernel acceleration.
+
+This capability is always enabled.
+
+4.98 KVM_CREATE_SPAPR_TCE_64
+
+Capability: KVM_CAP_SPAPR_TCE_64
+Architectures: powerpc
+Type: vm ioctl
+Parameters: struct kvm_create_spapr_tce_64 (in)
+Returns: file descriptor for manipulating the created TCE table
+
+This is an extension for KVM_CAP_SPAPR_TCE which only supports 32bit
+windows, described in 4.62 KVM_CREATE_SPAPR_TCE
+
+This capability uses extended struct in ioctl interface:
+
+/* for KVM_CAP_SPAPR_TCE_64 */
+struct kvm_create_spapr_tce_64 {
+ __u64 liobn;
+ __u32 page_shift;
+ __u32 flags;
+ __u64 offset; /* in pages */
+ __u64 size; /* in pages */
+};
+
+The aim of extension is to support an additional bigger DMA window with
+a variable page size.
+KVM_CREATE_SPAPR_TCE_64 receives a 64bit window size, an IOMMU page shift and
+a bus offset of the corresponding DMA window, @size and @offset are numbers
+of IOMMU pages.
+
+@flags are not used at the moment.
+
+The rest of functionality is identical to KVM_CREATE_SPAPR_TCE.

+ -ENXIO if KVM_CREATE_PIT or KVM_CREATE_PIT2 didn't succeed earlier.
+
+i8254 (PIT) has two modes, reinject and !reinject. The default is reinject,
+where KVM queues elapsed i8254 ticks and monitors completion of interrupt from
+vector(s) that i8254 injects. Reinject mode dequeues a tick and injects its
+interrupt whenever there isn't a pending interrupt from i8254.

+Generic vcpu interface
+====================================
+
+The virtual cpu "device" also accepts the ioctls KVM_SET_DEVICE_ATTR,
+KVM_GET_DEVICE_ATTR, and KVM_HAS_DEVICE_ATTR. The interface uses the same struct
+kvm_device_attr as other devices, but targets VCPU-wide settings and controls.

+
+Things changed when 64-bit support was added to x86 Linux. Rather than
+double the size of the exception table by expanding the two entries
+from 32-bits to 64 bits, a clever trick was used to store addresses
+as relative offsets from the table itself. The assembly code changed
+from:
+ .long 1b,3b
+to:
+ .long (from) - .
+ .long (to) - .

+ {
+ return (unsigned long)&x->insn + x->insn;

+
+In v4.6 the exception table entry was expanded with a new field "handler".
+This is also 32-bits wide and contains a third relative function
+pointer which points to one of:
+
+1) int ex_handler_default(const struct exception_table_entry *fixup)
+ This is legacy case that just jumps to the fixup code
+2) int ex_handler_fault(const struct exception_table_entry *fixup)

+ * Hypervisor exception vector and handlers
+ *
+ *
+ * The KVM/ARM Hypervisor ABI is defined as follows:
+ *
+ * Entry to Hyp mode from the host kernel will happen _only_ when an HVC
+ * instruction is issued since all traps are disabled when running the host
+ * kernel as per the Hyp-mode initialization at boot time.
+ *
+ * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc
+ * below) when the HVC instruction is called from SVC mode (i.e. a guest or the
+ * host kernel) and they cause a trap to the vector page + offset 0x8 when HVC
+ * instructions are called from within Hyp-mode.
+ *
+ * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
+ * Switching to Hyp mode is done through a simple HVC #0 instruction. The
+ * exception vector code will check that the HVC comes from VMID==0.
+ * - r0 contains a pointer to a HYP function
+ * - r1, r2, and r3 contain arguments to the above function.
+ * - The HYP function will be called with its arguments in r0, r1 and r2.
+ * On HYP function return, we return directly to SVC.
+ *
+ * Note that the above is used to execute code in Hyp-mode from a host-kernel
+ * point of view, and is a different concept from performing a world-switch and
+ * executing guest code SVC mode (with a VMID != 0).

- * instruction is issued since all traps are disabled when running the host
- * kernel as per the Hyp-mode initialization at boot time.
- *
- * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc

- * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
- * Switching to Hyp mode is done through a simple HVC #0 instruction. The
- * exception vector code will check that the HVC comes from VMID==0 and if
- * so will push the necessary state (SPSR, lr_usr) on the Hyp stack.
- * - r0 contains a pointer to a HYP function
- * - r1, r2, and r3 contain arguments to the above function.
- * - The HYP function will be called with its arguments in r0, r1 and r2.
- * On HYP function return, we return directly to SVC.
- *
- * Note that the above is used to execute code in Hyp-mode from a host-kernel
- * point of view, and is a different concept from performing a world-switch and

+ * of vblank timestamps could be active at the moment, as the current
+ * implementation of the timestamp caching and updating is not safe
+ * against concurrent readers for calls to store_vblank() with a bump

+ * timestamps to userspace, because the same slot in the cache could
+ * be concurrently written by store_vblank() and read by one of those
+ * readers without the read-retry logic detecting the collision.
+ *
+ * Concurrent readers can exist when we are called from the
+ * drm_vblank_off() or drm_vblank_on() functions and other non-vblank-
+ * irq callers. However, all those calls to us are happening with the
+ * vbl_lock locked to prevent drm_vblank_get(), so the vblank refcount
+ * can't increase while we are executing. Therefore a zero refcount at
+ * this point is safe for arbitrary counter bumps if we are called
+ * outside vblank irq, a non-zero count is not 100% safe. Unfortunately
+ * we must also accept a refcount of 1, as whenever we are called from
+ * drm_vblank_get() -> drm_vblank_enable() the refcount will be 1 and
+ * we must let that one pass through in order to not lose vblank counts
+ * during vblank irq off - which would completely defeat the whole
+ * point of this routine.
+ *
+ * Whenever we are called from vblank irq, we have to assume concurrent
+ * readers exist or can show up any time during our execution, even if
+ * the refcount is currently zero, as vblank irqs are usually only
+ * enabled due to the presence of readers, and because when we are called
+ * from vblank irq we can't hold the vbl_lock to protect us from sudden
+ * bumps in vblank refcount. Therefore also restrict bumps to +1 when

+ * multiple interfaces.
+ *
+ * 2) The databook does not mention doing more DEPXFERCFG for new
+ * endpoint on alt setting (8.1.6).
+ *
+ * The following simplified method is used instead:
+ *
+ * All hardware endpoints can be assigned a transfer resource and this
+ * setting will stay persistent until either a core reset or
+ * hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and
+ * do DEPXFERCFG for every hardware endpoint as well. We are
+ * guaranteed that there are as many transfer resources as endpoints.

+ * This function is called for each endpoint when it is being enabled
+ * but is triggered only when called for EP0-out, which always happens

Memory could be hotplugged in following steps:
- 1) dom0: xl mem-max <domU> <maxmem>
+ 1) target domain: ensure that memory auto online policy is in

+ file (should be 'online').

+ 2) control domain: xl mem-max <target-domain> <maxmem>
where <maxmem> is >= requested memory size,
- 2) dom0: xl mem-set <domU> <memory>
+ 3) control domain: xl mem-set <target-domain> <memory>
where <memory> is requested memory size; alternatively memory
could be added by writing proper value to
/sys/devices/system/xen_memory/xen_memory0/target or
- /sys/devices/system/xen_memory/xen_memory0/target_kb on dumU,
+ /sys/devices/system/xen_memory/xen_memory0/target_kb on the

- 3) domU: for i in /sys/devices/system/memory/memory*/state; do \
- [ "`cat "$i"`" = offline ] && echo online > "$i"; done
+ Alternatively, if memory auto onlining was not requested at step 1
+ the newly added memory can be manually onlined in the target domain
+ by doing the following:
- Memory could be onlined automatically on domU by adding following line to udev rules:
+ for i in /sys/devices/system/memory/memory*/state; do \
+ [ "`cat "$i"`" = offline ] && echo online > "$i"; done
+
+ or by adding the following line to udev rules:
SUBSYSTEM=="memory", ACTION=="add", RUN+="/bin/sh -c '[ -f /sys$devpath/state ] && echo online > /sys$devpath/state'"
- In that case step 3 should be omitted.

+ *
+ * - mixing INTERRUPTIBLE and UNINTERRUPTIBLE sleeps on the same waitqueue;
+ * all wakeups are TASK_NORMAL in order to avoid O(n) lookups for the right
+ * sleeper state.
+ *
+ * - the exclusive mode; because this requires preserving the list order
+ * and this is hard.

+ On 64-bit builds, this reduces the size of the address table by 50%,

+Variables
+~~~~~~~~~
+
+colors.*::
+ The variables for customizing the colors used in the output for the
+ 'report', 'top' and 'annotate' in the TUI. They should specify the
+ foreground and background colors, separated by a comma, for example:
+
+ medium = green, lightgray
+
+ If you want to use the color configured for you terminal, just leave it
+ as 'default', for example:
+
+ medium = default, lightgray
+
+ Available colors:
+ red, yellow, green, cyan, gray, black, blue,
+ white, default, magenta, lightgray
+
+ colors.top::
+ 'top' means a overhead percentage which is more than 5%.
+ And values of this variable specify percentage colors.
+ Basic key values are foreground-color 'red' and
+ background-color 'default'.
+ colors.medium::
+ 'medium' means a overhead percentage which has more than 0.5%.
+ Default values are 'green' and 'default'.
+ colors.normal::
+ 'normal' means the rest of overhead percentages
+ except 'top', 'medium', 'selected'.
+ Default values are 'lightgray' and 'default'.
+ colors.selected::
+ This selects the colors for the current entry in a list of entries
+ from sub-commands (top, report, annotate).
+ Default values are 'black' and 'lightgray'.
+ colors.jump_arrows::
+ Colors for jump arrows on assembly code listings
+ such as 'jns', 'jmp', 'jane', etc.
+ Default values are 'blue', 'default'.
+ colors.addr::
+ This selects colors for addresses from 'annotate'.
+ Default values are 'magenta', 'default'.
+ colors.root::
+ Colors for headers in the output of a sub-commands (top, report).
+ Default values are 'white', 'blue'.
+
+tui.*, gtk.*::
+ Subcommands that can be configured here are 'top', 'report' and 'annotate'.
+ These values are booleans, for example:
+
+ [tui]
+ top = true
+
+ will make the TUI be the default for the 'top' subcommand. Those will be
+ available if the required libs were detected at tool build time.
+
+buildid.*::
+ buildid.dir::
+ Each executable and shared library in modern distributions comes with a
+ content based identifier that, if available, will be inserted in a
+ 'perf.data' file header to, at analysis time find what is needed to do
+ symbol resolution, code annotation, etc.
+
+ The recording tools also stores a hard link or copy in a per-user
+ directory, $HOME/.debug/, of binaries, shared libraries, /proc/kallsyms
+ and /proc/kcore files to be used at analysis time.
+
+ The buildid.dir variable can be used to either change this directory
+ cache location, or to disable it altogether. If you want to disable it,
+ set buildid.dir to /dev/null. The default is $HOME/.debug
+
+annotate.*::
+ These options work only for TUI.
+ These are in control of addresses, jump function, source code
+ in lines of assembly code from a specific program.
+
+ annotate.hide_src_code::
+ If a program which is analyzed has source code,
+ this option lets 'annotate' print a list of assembly code with the source code.
+ For example, let's see a part of a program. There're four lines.
+ If this option is 'true', they can be printed
+ without source code from a program as below.
+
+ │ push %rbp
+ │ mov %rsp,%rbp
+ │ sub $0x10,%rsp
+ │ mov (%rdi),%rdx
+
+ But if this option is 'false', source code of the part
+ can be also printed as below. Default is 'false'.
+
+ │ struct rb_node *rb_next(const struct rb_node *node)
+ │ {
+ │ push %rbp
+ │ mov %rsp,%rbp
+ │ sub $0x10,%rsp
+ │ struct rb_node *parent;
+ │
+ │ if (RB_EMPTY_NODE(node))
+ │ mov (%rdi),%rdx
+ │ return n;
+
+ annotate.use_offset::
+ Basing on a first address of a loaded function, offset can be used.
+ Instead of using original addresses of assembly code,
+ addresses subtracted from a base address can be printed.
+ Let's illustrate an example.
+ If a base address is 0XFFFFFFFF81624d50 as below,
+
+ ffffffff81624d50 <load0>
+
+ an address on assembly code has a specific absolute address as below
+
+ ffffffff816250b8:│ mov 0x8(%r14),%rdi
+
+ but if use_offset is 'true', an address subtracted from a base address is printed.
+ Default is true. This option is only applied to TUI.
+
+ 368:│ mov 0x8(%r14),%rdi
+
+ annotate.jump_arrows::
+ There can be jump instruction among assembly code.
+ Depending on a boolean value of jump_arrows,
+ arrows can be printed or not which represent
+ where do the instruction jump into as below.
+
+ │ ┌──jmp 1333
+ │ │ xchg %ax,%ax
+ │1330:│ mov %r15,%r10
+ │1333:└─→cmp %r15,%r14
+
+ If jump_arrow is 'false', the arrows isn't printed as below.
+ Default is 'false'.
+
+ │ ↓ jmp 1333
+ │ xchg %ax,%ax
+ │1330: mov %r15,%r10
+ │1333: cmp %r15,%r14
+
+ annotate.show_linenr::
+ When showing source code if this option is 'true',
+ line numbers are printed as below.
+
+ │1628 if (type & PERF_SAMPLE_IDENTIFIER) {
+ │ ↓ jne 508
+ │1628 data->id = *array;
+ │1629 array++;
+ │1630 }
+
+ However if this option is 'false', they aren't printed as below.
+ Default is 'false'.
+
+ │ if (type & PERF_SAMPLE_IDENTIFIER) {
+ │ ↓ jne 508
+ │ data->id = *array;
+ │ array++;
+ │ }
+
+ annotate.show_nr_jumps::
+ Let's see a part of assembly code.
+
+ │1382: movb $0x1,-0x270(%rbp)
+
+ If use this, the number of branches jumping to that address can be printed as below.
+ Default is 'false'.
+
+ │1 1382: movb $0x1,-0x270(%rbp)
+
+ annotate.show_total_period::
+ To compare two records on an instruction base, with this option
+ provided, display total number of samples that belong to a line
+ in assembly code. If this option is 'true', total periods are printed
+ instead of percent values as below.
+
+ 302 │ mov %eax,%eax
+
+ But if this option is 'false', percent values for overhead are printed i.e.
+ Default is 'false'.
+
+ 99.93 │ mov %eax,%eax
+
+hist.*::
+ hist.percentage::
+ This option control the way to calculate overhead of filtered entries -
+ that means the value of this option is effective only if there's a
+ filter (by comm, dso or symbol name). Suppose a following example:
+
+ Overhead Symbols
+ ........ .......
+ 33.33% foo
+ 33.33% bar
+ 33.33% baz
+
+ This is an original overhead and we'll filter out the first 'foo'
+ entry. The value of 'relative' would increase the overhead of 'bar'
+ and 'baz' to 50.00% for each, while 'absolute' would show their
+ current overhead (33.33%).
+
+ui.*::
+ ui.show-headers::
+ This option controls display of column headers (like 'Overhead' and 'Symbol')
+ in 'report' and 'top'. If this option is false, they are hidden.
+ This option is only applied to TUI.
+
+call-graph.*::
+ When sub-commands 'top' and 'report' work with -g/—-children
+ there're options in control of call-graph.
+
+ call-graph.record-mode::
+ The record-mode can be 'fp' (frame pointer), 'dwarf' and 'lbr'.
+ The value of 'dwarf' is effective only if perf detect needed library
+ (libunwind or a recent version of libdw).
+ 'lbr' only work for cpus that support it.
+
+ call-graph.dump-size::
+ The size of stack to dump in order to do post-unwinding. Default is 8192 (byte).
+ When using dwarf into record-mode, the default size will be used if omitted.
+
+ call-graph.print-type::
+ The print-types can be graph (graph absolute), fractal (graph relative),
+ flat and folded. This option controls a way to show overhead for each callchain
+ entry. Suppose a following example.
+
+ Overhead Symbols
+ ........ .......
+ 40.00% foo
+ |
+ ---foo
+ |
+ |--50.00%--bar
+ | main
+ |
+ --50.00%--baz
+ main
+
+ This output is a 'fractal' format. The 'foo' came from 'bar' and 'baz' exactly
+ half and half so 'fractal' shows 50.00% for each
+ (meaning that it assumes 100% total overhead of 'foo').
+
+ The 'graph' uses absolute overhead value of 'foo' as total so each of
+ 'bar' and 'baz' callchain will have 20.00% of overhead.
+ If 'flat' is used, single column and linear exposure of call chains.
+ 'folded' mean call chains are displayed in a line, separated by semicolons.
+
+ call-graph.order::
+ This option controls print order of callchains. The default is
+ 'callee' which means callee is printed at top and then followed by its
+ caller and so on. The 'caller' prints it in reverse order.
+
+ If this option is not set and report.children or top.children is
+ set to true (or the equivalent command line option is given),
+ the default value of this option is changed to 'caller' for the
+ execution of 'perf report' or 'perf top'. Other commands will
+ still default to 'callee'.
+
+ call-graph.sort-key::
+ The callchains are merged if they contain same information.
+ The sort-key option determines a way to compare the callchains.
+ A value of 'sort-key' can be 'function' or 'address'.
+ The default is 'function'.
+
+ call-graph.threshold::
+ When there're many callchains it'd print tons of lines. So perf omits
+ small callchains under a certain overhead (threshold) and this option
+ control the threshold. Default is 0.5 (%). The overhead is calculated
+ by value depends on call-graph.print-type.
+
+ call-graph.print-limit::
+ This is a maximum number of lines of callchain printed for a single
+ histogram entry. Default is 0 which means no limitation.
+
+report.*::
+ report.percent-limit::
+ This one is mostly the same as call-graph.threshold but works for
+ histogram entries. Entries having an overhead lower than this
+ percentage will not be printed. Default is '0'. If percent-limit
+ is '10', only entries which have more than 10% of overhead will be
+ printed.
+
+ report.queue-size::
+ This option sets up the maximum allocation size of the internal
+ event queue for ordering events. Default is 0, meaning no limit.
+
+ report.children::
+ 'Children' means functions called from another function.
+ If this option is true, 'perf report' cumulates callchains of children
+ and show (accumulated) total overhead as well as 'Self' overhead.
+ Please refer to the 'perf report' manual. The default is 'true'.
+
+ report.group::
+ This option is to show event group information together.
+ Example output with this turned on, notice that there is one column
+ per event in the group, ref-cycles and cycles:
+
+ # group: {ref-cycles,cycles}
+ # ========
+ #
+ # Samples: 7K of event 'anon group { ref-cycles, cycles }'
+ # Event count (approx.): 6876107743
+ #
+ # Overhead Command Shared Object Symbol
+ # ................ ....... ................. ...................
+ #
+ 99.84% 99.76% noploop noploop [.] main
+ 0.07% 0.00% noploop ld-2.15.so [.] strcmp
+ 0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del
+
+top.*::
+ top.children::
+ Same as 'report.children'. So if it is enabled, the output of 'top'
+ command will have 'Children' overhead column as well as 'Self' overhead
+ column by default.
+ The default is 'true'.
+
+man.*::
+ man.viewer::
+ This option can assign a tool to view manual pages when 'help'
+ subcommand was invoked. Supported tools are 'man', 'woman'
+ (with emacs client) and 'konqueror'. Default is 'man'.
+
+ New man viewer tool can be also added using 'man.<tool>.cmd'
+ or use different path using 'man.<tool>.path' config option.
+
+pager.*::
+ pager.<subcommand>::
+ When the subcommand is run on stdio, determine whether it uses
+ pager or not based on this value. Default is 'unspecified'.
+
+kmem.*::
+ kmem.default::
+ This option decides which allocator is to be analyzed if neither
+ '--slab' nor '--page' option is used. Default is 'slab'.
+
+record.*::
+ record.build-id::
+ This option can be 'cache', 'no-cache' or 'skip'.
+ 'cache' is to post-process data and save/update the binaries into
+ the build-id cache (in ~/.debug). This is the default.
+ But if this option is 'no-cache', it will not update the build-id cache.
+ 'skip' skips post-processing and does not update the cache.
