+<constant>VIDIOC_REQBUFS</constant> ioctl, when a tighter control over buffers
+is required. This ioctl can be called multiple times to create buffers of
+different sizes.</para>
+
+ <para>To allocate device buffers applications initialize relevant fields of
+the <structname>v4l2_create_buffers</structname> structure. They set the
+<structfield>type</structfield> field in the
+<structname>v4l2_format</structname> structure, embedded in this
+structure, to the respective stream or buffer type.
+<structfield>count</structfield> must be set to the number of required buffers.
+<structfield>memory</structfield> specifies the required I/O method. The
+<structfield>format</structfield> field shall typically be filled in using
+either the <constant>VIDIOC_TRY_FMT</constant> or
+<constant>VIDIOC_G_FMT</constant> ioctl(). Additionally, applications can adjust
+<structfield>sizeimage</structfield> fields to fit their specific needs. The
+<structfield>reserved</structfield> array must be zeroed.</para>
+
+ <para>When the ioctl is called with a pointer to this structure the driver
+will attempt to allocate up to the requested number of buffers and store the
+actual number allocated and the starting index in the
+<structfield>count</structfield> and the <structfield>index</structfield> fields
+respectively. On return <structfield>count</structfield> can be smaller than
+the number requested. The driver may also increase buffer sizes if required,
+however, it will not update <structfield>sizeimage</structfield> field values.
+The user has to use <constant>VIDIOC_QUERYBUF</constant> to retrieve that
+information.</para>

+Introduction
+============
+
+The more-sophisticated device-mapper targets require complex metadata
+that is managed in kernel. In late 2010 we were seeing that various
+different targets were rolling their own data strutures, for example:
+
+- Mikulas Patocka's multisnap implementation
+- Heinz Mauelshagen's thin provisioning target
+- Another btree-based caching target posted to dm-devel
+- Another multi-snapshot target based on a design of Daniel Phillips
+
+Maintaining these data structures takes a lot of work, so if possible
+we'd like to reduce the number.
+
+The persistent-data library is an attempt to provide a re-usable
+framework for people who want to store metadata in device-mapper
+targets. It's currently used by the thin-provisioning target and an
+upcoming hierarchical storage target.
+
+Overview
+========
+
+The main documentation is in the header files which can all be found
+under drivers/md/persistent-data.
+
+The block manager
+-----------------
+
+dm-block-manager.[hc]
+
+This provides access to the data on disk in fixed sized-blocks. There
+is a read/write locking interface to prevent concurrent accesses, and
+keep data that is being used in the cache.
+
+Clients of persistent-data are unlikely to use this directly.
+
+The transaction manager
+-----------------------
+
+dm-transaction-manager.[hc]
+
+This restricts access to blocks and enforces copy-on-write semantics.
+The only way you can get hold of a writable block through the
+transaction manager is by shadowing an existing block (ie. doing
+copy-on-write) or allocating a fresh one. Shadowing is elided within
+the same transaction so performance is reasonable. The commit method
+ensures that all data is flushed before it writes the superblock.
+On power failure your metadata will be as it was when last committed.
+
+The Space Maps
+--------------
+
+dm-space-map.h
+dm-space-map-metadata.[hc]
+dm-space-map-disk.[hc]
+
+On-disk data structures that keep track of reference counts of blocks.
+Also acts as the allocator of new blocks. Currently two
+implementations: a simpler one for managing blocks on a different
+device (eg. thinly-provisioned data blocks); and one for managing
+the metadata space. The latter is complicated by the need to store
+its own data within the space it's managing.
+
+The data structures
+-------------------
+
+dm-btree.[hc]
+dm-btree-remove.c
+dm-btree-spine.c
+dm-btree-internal.h
+
+Currently there is only one data structure, a hierarchical btree.
+There are plans to add more. For example, something with an
+array-like interface would see a lot of use.
+
+The btree is 'hierarchical' in that you can define it to be composed
+of nested btrees, and take multiple keys. For example, the
+thin-provisioning target uses a btree with two levels of nesting.
+The first maps a device id to a mapping tree, and that in turn maps a
+virtual block to a physical block.
+
+Values stored in the btrees can have arbitrary size. Keys are always
+64bits, although nesting allows you to use multiple keys.

+Introduction
+============
+
+This document descibes a collection of device-mapper targets that
+between them implement thin-provisioning and snapshots.
+
+The main highlight of this implementation, compared to the previous
+implementation of snapshots, is that it allows many virtual devices to
+be stored on the same data volume. This simplifies administration and
+allows the sharing of data between volumes, thus reducing disk usage.
+
+Another significant feature is support for an arbitrary depth of
+recursive snapshots (snapshots of snapshots of snapshots ...). The
+previous implementation of snapshots did this by chaining together
+lookup tables, and so performance was O(depth). This new
+implementation uses a single data structure to avoid this degradation
+with depth. Fragmentation may still be an issue, however, in some
+scenarios.
+
+Metadata is stored on a separate device from data, giving the
+administrator some freedom, for example to:
+
+- Improve metadata resilience by storing metadata on a mirrored volume
+ but data on a non-mirrored one.
+
+- Improve performance by storing the metadata on SSD.
+
+Status
+======
+
+These targets are very much still in the EXPERIMENTAL state. Please
+do not yet rely on them in production. But do experiment and offer us
+feedback. Different use cases will have different performance
+characteristics, for example due to fragmentation of the data volume.
+
+If you find this software is not performing as expected please mail
+dm-devel@redhat.com with details and we'll try our best to improve
+things for you.
+
+Userspace tools for checking and repairing the metadata are under
+development.
+
+Cookbook
+========
+
+This section describes some quick recipes for using thin provisioning.
+They use the dmsetup program to control the device-mapper driver
+directly. End users will be advised to use a higher-level volume
+manager such as LVM2 once support has been added.
+
+Pool device
+-----------
+
+The pool device ties together the metadata volume and the data volume.
+It maps I/O linearly to the data volume and updates the metadata via
+two mechanisms:
+
+- Function calls from the thin targets
+
+- Device-mapper 'messages' from userspace which control the creation of new
+ virtual devices amongst other things.
+
+Setting up a fresh pool device
+------------------------------
+
+Setting up a pool device requires a valid metadata device, and a
+data device. If you do not have an existing metadata device you can
+make one by zeroing the first 4k to indicate empty metadata.
+
+ dd if=/dev/zero of=$metadata_dev bs=4096 count=1
+
+The amount of metadata you need will vary according to how many blocks
+are shared between thin devices (i.e. through snapshots). If you have
+less sharing than average you'll need a larger-than-average metadata device.
+
+As a guide, we suggest you calculate the number of bytes to use in the
+metadata device as 48 * $data_dev_size / $data_block_size but round it up
+to 2MB if the answer is smaller. The largest size supported is 16GB.
+
+If you're creating large numbers of snapshots which are recording large
+amounts of change, you may need find you need to increase this.
+
+Reloading a pool table
+----------------------
+
+You may reload a pool's table, indeed this is how the pool is resized
+if it runs out of space. (N.B. While specifying a different metadata
+device when reloading is not forbidden at the moment, things will go
+wrong if it does not route I/O to exactly the same on-disk location as
+previously.)
+
+Using an existing pool device
+-----------------------------
+
+ dmsetup create pool \
+ --table "0 20971520 thin-pool $metadata_dev $data_dev \
+ $data_block_size $low_water_mark"
+
+$data_block_size gives the smallest unit of disk space that can be
+allocated at a time expressed in units of 512-byte sectors. People
+primarily interested in thin provisioning may want to use a value such
+as 1024 (512KB). People doing lots of snapshotting may want a smaller value
+such as 128 (64KB). If you are not zeroing newly-allocated data,
+a larger $data_block_size in the region of 256000 (128MB) is suggested.
+$data_block_size must be the same for the lifetime of the
+metadata device.
+
+$low_water_mark is expressed in blocks of size $data_block_size. If
+free space on the data device drops below this level then a dm event
+will be triggered which a userspace daemon should catch allowing it to
+extend the pool device. Only one such event will be sent.
+Resuming a device with a new table itself triggers an event so the
+userspace daemon can use this to detect a situation where a new table
+already exceeds the threshold.
+
+Thin provisioning
+-----------------
+
+i) Creating a new thinly-provisioned volume.
+
+ To create a new thinly- provisioned volume you must send a message to an
+ active pool device, /dev/mapper/pool in this example.
+
+ dmsetup message /dev/mapper/pool 0 "create_thin 0"
+
+ Here '0' is an identifier for the volume, a 24-bit number. It's up
+ to the caller to allocate and manage these identifiers. If the
+ identifier is already in use, the message will fail with -EEXIST.
+
+ii) Using a thinly-provisioned volume.
+
+ Thinly-provisioned volumes are activated using the 'thin' target:
+
+ dmsetup create thin --table "0 2097152 thin /dev/mapper/pool 0"
+
+ The last parameter is the identifier for the thinp device.
+
+Internal snapshots
+------------------
+
+i) Creating an internal snapshot.
+
+ Snapshots are created with another message to the pool.
+
+ N.B. If the origin device that you wish to snapshot is active, you
+ must suspend it before creating the snapshot to avoid corruption.
+ This is NOT enforced at the moment, so please be careful!
+
+ dmsetup suspend /dev/mapper/thin
+ dmsetup message /dev/mapper/pool 0 "create_snap 1 0"
+ dmsetup resume /dev/mapper/thin
+
+ Here '1' is the identifier for the volume, a 24-bit number. '0' is the
+ identifier for the origin device.
+
+ii) Using an internal snapshot.
+
+ Once created, the user doesn't have to worry about any connection
+ between the origin and the snapshot. Indeed the snapshot is no
+ different from any other thinly-provisioned device and can be
+ snapshotted itself via the same method. It's perfectly legal to
+ have only one of them active, and there's no ordering requirement on
+ activating or removing them both. (This differs from conventional
+ device-mapper snapshots.)
+
+ Activate it exactly the same way as any other thinly-provisioned volume:
+
+ dmsetup create snap --table "0 2097152 thin /dev/mapper/pool 1"
+
+Deactivation
+------------
+
+All devices using a pool must be deactivated before the pool itself
+can be.
+
+ dmsetup remove thin
+ dmsetup remove snap
+ dmsetup remove pool
+
+Reference
+=========
+
+'thin-pool' target
+------------------
+
+i) Constructor
+
+ thin-pool <metadata dev> <data dev> <data block size (sectors)> \
+ <low water mark (blocks)> [<number of feature args> [<arg>]*]
+
+ Optional feature arguments:
+ - 'skip_block_zeroing': skips the zeroing of newly-provisioned blocks.
+
+ Data block size must be between 64KB (128 sectors) and 1GB
+ (2097152 sectors) inclusive.
+
+
+ii) Status
+
+ <transaction id> <used metadata blocks>/<total metadata blocks>
+ <used data blocks>/<total data blocks> <held metadata root>
+
+
+ transaction id:
+ A 64-bit number used by userspace to help synchronise with metadata
+ from volume managers.
+
+ used data blocks / total data blocks
+ If the number of free blocks drops below the pool's low water mark a
+ dm event will be sent to userspace. This event is edge-triggered and
+ it will occur only once after each resume so volume manager writers
+ should register for the event and then check the target's status.
+
+ held metadata root:
+ The location, in sectors, of the metadata root that has been
+ 'held' for userspace read access. '-' indicates there is no
+ held root. This feature is not yet implemented so '-' is
+ always returned.
+
+iii) Messages
+
+ create_thin <dev id>
+
+ Create a new thinly-provisioned device.
+ <dev id> is an arbitrary unique 24-bit identifier chosen by
+ the caller.
+
+ create_snap <dev id> <origin id>
+
+ Create a new snapshot of another thinly-provisioned device.
+ <dev id> is an arbitrary unique 24-bit identifier chosen by
+ the caller.
+ <origin id> is the identifier of the thinly-provisioned device
+ of which the new device will be a snapshot.
+
+ delete <dev id>
+
+ Deletes a thin device. Irreversible.
+
+ trim <dev id> <new size in sectors>
+
+ Delete mappings from the end of a thin device. Irreversible.
+ You might want to use this if you're reducing the size of
+ your thinly-provisioned device. In many cases, due to the
+ sharing of blocks between devices, it is not possible to
+ determine in advance how much space 'trim' will release. (In
+ future a userspace tool might be able to perform this
+ calculation.)
+
+ set_transaction_id <current id> <new id>
+
+ Userland volume managers, such as LVM, need a way to
+ synchronise their external metadata with the internal metadata of the
+ pool target. The thin-pool target offers to store an
+ arbitrary 64-bit transaction id and return it on the target's
+ status line. To avoid races you must provide what you think
+ the current transaction id is when you change it with this
+ compare-and-swap message.
+
+'thin' target
+-------------
+
+i) Constructor
+
+ thin <pool dev> <dev id>
+
+ pool dev:
+ the thin-pool device, e.g. /dev/mapper/my_pool or 253:0
+
+ dev id:
+ the internal device identifier of the device to be
+ activated.
+
+The pool doesn't store any size against the thin devices. If you
+load a thin target that is smaller than you've been using previously,
+then you'll have no access to blocks mapped beyond the end. If you
+load a target that is bigger than before, then extra blocks will be
+provisioned as and when needed.
+
+If you wish to reduce the size of your thin device and potentially
+regain some space then send the 'trim' message to the pool.
+
+ii) Status
+
+ <nr mapped sectors> <highest mapped sector>

+ARM SMP cores are often associated with a GIC, providing per processor
+interrupts (PPI), shared processor interrupts (SPI) and software
+generated interrupts (SGI).
+
+Primary GIC is attached directly to the CPU and typically has PPIs and SGIs.
+Secondary GICs are cascaded into the upward interrupt controller and do not
+have PPIs or SGIs.
+
+Main node required properties:
+
+- compatible : should be one of:
+ "arm,cortex-a9-gic"
+ "arm,arm11mp-gic"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 3.
+
+ The 1st cell is the interrupt type; 0 for SPI interrupts, 1 for PPI
+ interrupts.
+
+ The 2nd cell contains the interrupt number for the interrupt type.
+ SPI interrupts are in the range [0-987]. PPI interrupts are in the
+ range [0-15].
+
+ The 3rd cell is the flags, encoded as follows:
+ bits[3:0] trigger type and level flags.
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+ bits[15:8] PPI interrupt cpu mask. Each bit corresponds to each of
+ the 8 possible cpus attached to the GIC. A bit set to '1' indicated
+ the interrupt is wired to that CPU. Only valid for PPI interrupts.
+
+- reg : Specifies base physical address(s) and size of the GIC registers. The
+ first region is the GIC distributor register base and size. The 2nd region is
+ the GIC cpu interface register base and size.
+
+Optional
+- interrupts : Interrupt source of the parent interrupt controller. Only
+ present on secondary GICs.
+
+Example:
+
+ intc: interrupt-controller@fff11000 {
+ compatible = "arm,cortex-a9-gic";
+ #interrupt-cells = <3>;
+ #address-cells = <1>;
+ interrupt-controller;
+ reg = <0xfff11000 0x1000>,
+ <0xfff10100 0x100>;
+ };

-
- Binary sysctls are a long standing source of subtle kernel

-

- space programs.
-
- sysctl(2) is not generally ABI compatible to a 32bit user
- space application on a 64bit and a 32bit kernel.
-
- For the last several months the policy has been no new binary
- sysctls and no one has put forward an argument to use them.
-
- Binary sysctls issues seem to keep happening appearing so
- properly deprecating them (with a warning to user space) and a
- 2 year grace warning period will mean eventually we can kill

- In the mean time individual binary sysctls can be dealt with

+RapidIO subsystem mport driver for IDT Tsi721 PCI Express-to-SRIO bridge.
+=========================================================================
+
+I. Overview
+
+This driver implements all currently defined RapidIO mport callback functions.
+It supports maintenance read and write operations, inbound and outbound RapidIO
+doorbells, inbound maintenance port-writes and RapidIO messaging.
+
+To generate SRIO maintenance transactions this driver uses one of Tsi721 DMA
+channels. This mechanism provides access to larger range of hop counts and
+destination IDs without need for changes in outbound window translation.
+
+RapidIO messaging support uses dedicated messaging channels for each mailbox.
+For inbound messages this driver uses destination ID matching to forward messages
+into the corresponding message queue. Messaging callbacks are implemented to be
+fully compatible with RIONET driver (Ethernet over RapidIO messaging services).
+
+II. Known problems
+
+ None.
+
+III. To do
+
+ Add DMA data transfers (non-messaging).
+ Add inbound region (SRIO-to-PCIe) mapping.
+
+IV. Version History
+
+ 1.0.0 - Initial driver release.

+ *
+ * 24xx does not support programmable sleep dependencies (SLEEPDEP)

+ * value are the same for all powerdomains: 2
+ *
+ * XXX should dep_bit be a mask, so we can test to see if it is 0 as a

+ * This file contains clockdomains and clockdomain wakeup dependencies
+ * for OMAP2xxx chips. Some notes:
+ *
+ * A useful validation rule for struct clockdomain: Any clockdomain
+ * referenced by a wkdep_srcs must have a dep_bit assigned. So
+ * wkdep_srcs are really just software-controllable dependencies.
+ * Non-software-controllable dependencies do exist, but they are not
+ * encoded below (yet).
+ *
+ * 24xx does not support programmable sleep dependencies (SLEEPDEP)
+ *
+ * The overly-specific dep_bit names are due to a bit name collision
+ * with CM_FCLKEN_{DSP,IVA2}. The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
+ * value are the same for all powerdomains: 2
+ *
+ * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
+ * sanity check?
+ * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE

+ *
+ * A useful validation rule for struct clockdomain: Any clockdomain

+ * dep_bit assigned. So wkdep_srcs/sleepdep_srcs are really just
+ * software-controllable dependencies. Non-software-controllable
+ * dependencies do exist, but they are not encoded below (yet).
+ *
+ * The overly-specific dep_bit names are due to a bit name collision
+ * with CM_FCLKEN_{DSP,IVA2}. The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
+ * value are the same for all powerdomains: 2
+ *
+ * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
+ * sanity check?
+ * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE

+ * Description
+ *
+ * library function for memcpy where length bytes are copied from
+ * ptr_in to ptr_out. ptr_out is returned unchanged.
+ * Allows any combination of alignment on input and output pointers
+ * and length from 0 to 2^32-1
+ *
+ * Restrictions
+ * The arrays should not overlap, the program will produce undefined output
+ * if they do.
+ * For blocks less than 16 bytes a byte by byte copy is performed. For
+ * 8byte alignments, and length multiples, a dword copy is performed up to
+ * 96bytes
+ * History
+ *
+ * DJH 5/15/09 Initial version 1.0
+ * DJH 6/ 1/09 Version 1.1 modified ABI to inlcude R16-R19
+ * DJH 7/12/09 Version 1.2 optimized codesize down to 760 was 840
+ * DJH 10/14/09 Version 1.3 added special loop for aligned case, was
+ * overreading bloated codesize back up to 892
+ * DJH 4/20/10 Version 1.4 fixed Ldword_loop_epilog loop to prevent loads
+ * occuring if only 1 left outstanding, fixes bug
+ * # 3888, corrected for all alignments. Peeled off
+ * 1 32byte chunk from kernel loop and extended 8byte
+ * loop at end to solve all combinations and prevent
+ * over read. Fixed Ldword_loop_prolog to prevent
+ * overread for blocks less than 48bytes. Reduced
+ * codesize to 752 bytes
+ * DJH 4/21/10 version 1.5 1.4 fix broke code for input block ends not
+ * aligned to dword boundaries,underwriting by 1
+ * byte, added detection for this and fixed. A
+ * little bloat.
+ * DJH 4/23/10 version 1.6 corrected stack error, R20 was not being restored
+ * always, fixed the error of R20 being modified
+ * before it was being saved
+ * Natural c model

- A pseudo terminal (PTY) is a software device consisting of two

- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.

- This option enables UML's "hardware" random number generator. It

- generator, major 10, minor 183, and the canonical device name is

- The way to make use of this is to install the rng-tools package

- * read_barrier_depends - Flush all pending reads that subsequents reads

- *
- * 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.

- * read_barrier_depends - Flush all pending reads that subsequents reads

- *
- * 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.

+ * This is a SIMD SHA-1 implementation. It requires the Intel(R) Supplemental
+ * SSE3 instruction set extensions introduced in Intel Core Microarchitecture
+ * processors. CPUs supporting Intel(R) AVX extensions will get an additional
+ * boost.
+ *
+ * This work was inspired by the vectorized implementation of Dean Gaudet.
+ * Additional information on it can be found at:
+ * http://www.arctic.org/~dean/crypto/sha1.html
+ *
+ * It was improved upon with more efficient vectorization of the message
+ * scheduling. This implementation has also been optimized for all current and
+ * several future generations of Intel CPUs.
+ *
+ * See this article for more information about the implementation details:

+ * 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.

+ This option enables UML's "hardware" random number generator. It
+ attaches itself to the host's /dev/random, supplying as much entropy
+ as the host has, rather than the small amount the UML gets from its
+ own drivers. It registers itself as a standard hardware random number
+ generator, major 10, minor 183, and the canonical device name is
+ /dev/hwrng.
+ The way to make use of this is to install the rng-tools package
+ (check your distro, or download from
+ http://sourceforge.net/projects/gkernel/). rngd periodically reads
+ /dev/hwrng and injects the entropy into /dev/random.

-/*
- * There are several things to be aware of that aren't at all obvious:
- *
- *
- * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
- *
- * These are some of the many terms that are thrown about that don't always
- * mean what people think they mean (Inconceivable!). In the interest of
- * creating a common ground for discussion, terms and their definitions
- * will be established.
- *
- * Memory devices: The individual chip on a memory stick. These devices
- * commonly output 4 and 8 bits each. Grouping several
- * of these in parallel provides 64 bits which is common
- * for a memory stick.
- *
- * Memory Stick: A printed circuit board that aggregates multiple
- * memory devices in parallel. This is the atomic
- * memory component that is purchaseable by Joe consumer
- * and loaded into a memory socket.
- *
- * Socket: A physical connector on the motherboard that accepts
- * a single memory stick.
- *
- * Channel: Set of memory devices on a memory stick that must be
- * grouped in parallel with one or more additional
- * channels from other memory sticks. This parallel
- * grouping of the output from multiple channels are
- * necessary for the smallest granularity of memory access.
- * Some memory controllers are capable of single channel -
- * which means that memory sticks can be loaded
- * individually. Other memory controllers are only
- * capable of dual channel - which means that memory
- * sticks must be loaded as pairs (see "socket set").
- *
- * Chip-select row: All of the memory devices that are selected together.
- * for a single, minimum grain of memory access.
- * This selects all of the parallel memory devices across
- * all of the parallel channels. Common chip-select rows
- * for single channel are 64 bits, for dual channel 128
- * bits.
- *
- * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
- * Motherboards commonly drive two chip-select pins to
- * a memory stick. A single-ranked stick, will occupy
- * only one of those rows. The other will be unused.
- *
- * Double-Ranked stick: A double-ranked stick has two chip-select rows which
- * access different sets of memory devices. The two
- * rows cannot be accessed concurrently.
- *
- * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
- * A double-sided stick has two chip-select rows which
- * access different sets of memory devices. The two
- * rows cannot be accessed concurrently. "Double-sided"
- * is irrespective of the memory devices being mounted
- * on both sides of the memory stick.
- *
- * Socket set: All of the memory sticks that are required for
- * a single memory access or all of the memory sticks
- * spanned by a chip-select row. A single socket set
- * has two chip-select rows and if double-sided sticks
- * are used these will occupy those chip-select rows.
- *
- * Bank: This term is avoided because it is unclear when
- * needing to distinguish between chip-select rows and
- * socket sets.
- *

- *
- * Physical pages:

- * USB ATI Remote support
- *
- * Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
- * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
- *
- * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
- * porting to the 2.6 kernel interfaces, along with other modification
- * to better match the style of the existing usb/input drivers. However, the
- * protocol and hardware handling is essentially unchanged from 2.1.1.
- *
- * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
- * Vojtech Pavlik.
- *
- * Changes:
- *
- * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
- * Version 2.2.0
- * Jun 2004: Torrey Hoffman <thoffman@arnor.net>
- * Version 2.2.1
- * Added key repeat support contributed by:
- * Vincent Vanackere <vanackere@lif.univ-mrs.fr>
- * Added support for the "Lola" remote contributed by:
- * Seth Cohn <sethcohn@yahoo.com>

- * Hardware & software notes
- *
- * These remote controls are distributed by ATI as part of their
- * "All-In-Wonder" video card packages. The receiver self-identifies as a
- * "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
- *
- * The "Lola" remote is available from X10. See:
- * http://www.x10.com/products/lola_sg1.htm
- * The Lola is similar to the ATI remote but has no mouse support, and slightly
- * different keys.
- *
- * It is possible to use multiple receivers and remotes on multiple computers
- * simultaneously by configuring them to use specific channels.
- *
- * The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
- * Actually, it may even support more, at least in some revisions of the
- * hardware.
- *
- * Each remote can be configured to transmit on one channel as follows:
- * - Press and hold the "hand icon" button.
- * - When the red LED starts to blink, let go of the "hand icon" button.
- * - When it stops blinking, input the channel code as two digits, from 01
- * to 16, and press the hand icon again.
- *
- * The timing can be a little tricky. Try loading the module with debug=1
- * to have the kernel print out messages about the remote control number
- * and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
- *
- * The driver has a "channel_mask" parameter. This bitmask specifies which
- * channels will be ignored by the module. To mask out channels, just add
- * all the 2^channel_number values together.
- *
- * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
- * ignore signals coming from remote controls transmitting on channel 4, but
- * accept all other channels.
- *
- * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
- * ignored.
- *
- * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
- * parameter are unused.
- *

+ This option enables build of the LED TPU platform driver,

+ The driver controls the GPIO pin connected to the LED via

+ a pin that can be driven in both GPIO mode and using TPU
+ pin function. The latter to support brightness control.
+ Brightness control is supported but hardware blinking is not.

+ * As far as the metadata goes, there is:
+ *
+ * - A superblock in block zero, taking up fewer than 512 bytes for
+ * atomic writes.
+ *
+ * - A space map managing the metadata blocks.
+ *
+ * - A space map managing the data blocks.
+ *
+ * - A btree mapping our internal thin dev ids onto struct disk_device_details.
+ *
+ * - A hierarchical btree, with 2 levels which effectively maps (thin
+ * dev id, virtual block) -> block_time. Block time is a 64-bit
+ * field holding the time in the low 24 bits, and block in the top 48
+ * bits.
+ *
+ * BTrees consist solely of btree_nodes, that fill a block. Some are
+ * internal nodes, as such their values are a __le64 pointing to other
+ * nodes. Leaf nodes can store data of any reasonable size (ie. much
+ * smaller than the block size). The nodes consist of the header,
+ * followed by an array of keys, followed by an array of values. We have
+ * to binary search on the keys so they're all held together to help the
+ * cpu cache.
+ *
+ * Space maps have 2 btrees:
+ *
+ * - One maps a uint64_t onto a struct index_entry. Which points to a
+ * bitmap block, and has some details about how many free entries there
+ * are etc.
+ *
+ * - The bitmap blocks have a header (for the checksum). Then the rest
+ * of the block is pairs of bits. With the meaning being:
+ *
+ * 0 - ref count is 0
+ * 1 - ref count is 1
+ * 2 - ref count is 2
+ * 3 - ref count is higher than 2
+ *
+ * - If the count is higher than 2 then the ref count is entered in a
+ * second btree that directly maps the block_address to a uint32_t ref
+ * count.
+ *
+ * The space map metadata variant doesn't have a bitmaps btree. Instead
+ * it has one single blocks worth of index_entries. This avoids
+ * recursive issues with the bitmap btree needing to allocate space in
+ * order to insert. With a small data block size such as 64k the
+ * metadata support data devices that are hundreds of terrabytes.
+ *
+ * The space maps allocate space linearly from front to back. Space that
+ * is freed in a transaction is never recycled within that transaction.
+ * To try and avoid fragmenting _free_ space the allocator always goes
+ * back and fills in gaps.
+ *
+ * All metadata io is in THIN_METADATA_BLOCK_SIZE sized/aligned chunks
+ * from the block manager.

+ * How do we handle breaking sharing of data blocks?
+ * =================================================
+ *
+ * We use a standard copy-on-write btree to store the mappings for the
+ * devices (note I'm talking about copy-on-write of the metadata here, not
+ * the data). When you take an internal snapshot you clone the root node
+ * of the origin btree. After this there is no concept of an origin or a
+ * snapshot. They are just two device trees that happen to point to the
+ * same data blocks.
+ *
+ * When we get a write in we decide if it's to a shared data block using
+ * some timestamp magic. If it is, we have to break sharing.
+ *
+ * Let's say we write to a shared block in what was the origin. The
+ * steps are:
+ *
+ * i) plug io further to this physical block. (see bio_prison code).
+ *
+ * ii) quiesce any read io to that shared data block. Obviously
+ * including all devices that share this block. (see deferred_set code)
+ *
+ * iii) copy the data block to a newly allocate block. This step can be
+ * missed out if the io covers the block. (schedule_copy).
+ *
+ * iv) insert the new mapping into the origin's btree
+ * (process_prepared_mappings). This act of inserting breaks some
+ * sharing of btree nodes between the two devices. Breaking sharing only
+ * effects the btree of that specific device. Btrees for the other
+ * devices that share the block never change. The btree for the origin
+ * device as it was after the last commit is untouched, ie. we're using
+ * persistent data structures in the functional programming sense.
+ *
+ * v) unplug io to this physical block, including the io that triggered
+ * the breaking of sharing.
+ *
+ * Steps (ii) and (iii) occur in parallel.
+ *
+ * The metadata _doesn't_ need to be committed before the io continues. We
+ * get away with this because the io is always written to a _new_ block.
+ * If there's a crash, then:
+ *
+ * - The origin mapping will point to the old origin block (the shared
+ * one). This will contain the data as it was before the io that triggered
+ * the breaking of sharing came in.
+ *
+ * - The snap mapping still points to the old block. As it would after
+ * the commit.
+ *
+ * The downside of this scheme is the timestamp magic isn't perfect, and
+ * will continue to think that data block in the snapshot device is shared
+ * even after the write to the origin has broken sharing. I suspect data
+ * blocks will typically be shared by many different devices, so we're
+ * breaking sharing n + 1 times, rather than n, where n is the number of
+ * devices that reference this data block. At the moment I think the
+ * benefits far, far outweigh the disadvantages.

+ * Removing an entry from a btree
+ * ==============================
+ *
+ * A very important constraint for our btree is that no node, except the
+ * root, may have fewer than a certain number of entries.
+ * (MIN_ENTRIES <= nr_entries <= MAX_ENTRIES).
+ *
+ * Ensuring this is complicated by the way we want to only ever hold the
+ * locks on 2 nodes concurrently, and only change nodes in a top to bottom
+ * fashion.
+ *
+ * Each node may have a left or right sibling. When decending the spine,
+ * if a node contains only MIN_ENTRIES then we try and increase this to at
+ * least MIN_ENTRIES + 1. We do this in the following ways:
+ *
+ * [A] No siblings => this can only happen if the node is the root, in which
+ * case we copy the childs contents over the root.
+ *
+ * [B] No left sibling
+ * ==> rebalance(node, right sibling)
+ *
+ * [C] No right sibling
+ * ==> rebalance(left sibling, node)
+ *
+ * [D] Both siblings, total_entries(left, node, right) <= DEL_THRESHOLD
+ * ==> delete node adding it's contents to left and right
+ *
+ * [E] Both siblings, total_entries(left, node, right) > DEL_THRESHOLD
+ * ==> rebalance(left, node, right)
+ *
+ * After these operations it's possible that the our original node no
+ * longer contains the desired sub tree. For this reason this rebalancing
+ * is performed on the children of the current node. This also avoids
+ * having a special case for the root.
+ *
+ * Once this rebalancing has occurred we can then step into the child node
+ * for internal nodes. Or delete the entry for leaf nodes.

+ * Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
+ *
+ * This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
+ * porting to the 2.6 kernel interfaces, along with other modification
+ * to better match the style of the existing usb/input drivers. However, the
+ * protocol and hardware handling is essentially unchanged from 2.1.1.
+ *
+ * The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
+ * Vojtech Pavlik.
+ *
+ * Changes:
+ *
+ * Feb 2004: Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.2.0
+ * Jun 2004: Torrey Hoffman <thoffman@arnor.net>
+ * Version 2.2.1
+ * Added key repeat support contributed by:

+ * Hardware & software notes
+ *
+ * These remote controls are distributed by ATI as part of their
+ * "All-In-Wonder" video card packages. The receiver self-identifies as a
+ * "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
+ *
+ * The "Lola" remote is available from X10. See:
+ * http://www.x10.com/products/lola_sg1.htm
+ * The Lola is similar to the ATI remote but has no mouse support, and slightly
+ * different keys.
+ *
+ * It is possible to use multiple receivers and remotes on multiple computers
+ * simultaneously by configuring them to use specific channels.
+ *
+ * The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
+ * Actually, it may even support more, at least in some revisions of the
+ * hardware.
+ *
+ * Each remote can be configured to transmit on one channel as follows:
+ * - Press and hold the "hand icon" button.
+ * - When the red LED starts to blink, let go of the "hand icon" button.
+ * - When it stops blinking, input the channel code as two digits, from 01
+ * to 16, and press the hand icon again.
+ *
+ * The timing can be a little tricky. Try loading the module with debug=1
+ * to have the kernel print out messages about the remote control number
+ * and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
+ *
+ * The driver has a "channel_mask" parameter. This bitmask specifies which
+ * channels will be ignored by the module. To mask out channels, just add
+ * all the 2^channel_number values together.
+ *
+ * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
+ * ignore signals coming from remote controls transmitting on channel 4, but
+ * accept all other channels.
+ *
+ * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
+ * ignored.
+ *
+ * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
+ * parameter are unused.

- Multifunction devices embed several functions (e.g. GPIOs,
- touchscreens, keyboards, current regulators, power management chips,
- etc...) in one single integrated circuit. They usually talk to the
- main CPU through one or more IRQ lines and low speed data busses (SPI,
- I2C, etc..). They appear as one single device to the main system
- through the data bus and the MFD framework allows for sub devices
- (a.k.a. functions) to appear as discrete platform devices.
- MFDs are typically found on embedded platforms.
-
- This option alone does not add any kernel code.

-Todo:
- - Fix the loss of some blocks when receiving the video URB's
- - Add a lock at tm6000_read_write_usb() to prevent two simultaneous access to the
- URB control transfers
- - Properly add the locks at tm6000-video
- - Add audio support
- - Add vbi support
- - Add IR support
- - Do several cleanups
- - I think that frame1/frame0 are inverted. This causes a funny effect at the image.
- the fix is trivial, but require some tests
- - My tm6010 devices sometimes insist on stop working. I need to turn them off, removing
- from my machine and wait for a while for it to work again. I'm starting to think that
- it is an overheat issue - is there a workaround that we could do?
- - Sometimes, tm6010 doesn't read eeprom at the proper time (hardware bug). So, the device
- got miss-detected as a "generic" tm6000. This can be really bad if the tuner is the
- Low Power one, as it may result on loading the high power firmware, that could damage
- the device. Maybe we may read eeprom to double check, when the device is marked as "generic"
- - Coding Style fixes
- - sparse cleanups

+ * are not delalloc'ed.
+ * Ex:

+ * ==> 4 complete clusters in above example
+ *
+ * (b) partial cluster (outside of allocated range) towards either end is

+ * There are several things to be aware of that aren't at all obvious:
+ *
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!). In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices: The individual chip on a memory stick. These devices
+ * commonly output 4 and 8 bits each. Grouping several
+ * of these in parallel provides 64 bits which is common
+ * for a memory stick.
+ *
+ * Memory Stick: A printed circuit board that aggregates multiple
+ * memory devices in parallel. This is the atomic
+ * memory component that is purchaseable by Joe consumer
+ * and loaded into a memory socket.
+ *
+ * Socket: A physical connector on the motherboard that accepts
+ * a single memory stick.
+ *
+ * Channel: Set of memory devices on a memory stick that must be
+ * grouped in parallel with one or more additional
+ * channels from other memory sticks. This parallel
+ * grouping of the output from multiple channels are
+ * necessary for the smallest granularity of memory access.
+ * Some memory controllers are capable of single channel -
+ * which means that memory sticks can be loaded
+ * individually. Other memory controllers are only
+ * capable of dual channel - which means that memory
+ * sticks must be loaded as pairs (see "socket set").
+ *
+ * Chip-select row: All of the memory devices that are selected together.
+ * for a single, minimum grain of memory access.
+ * This selects all of the parallel memory devices across
+ * all of the parallel channels. Common chip-select rows
+ * for single channel are 64 bits, for dual channel 128
+ * bits.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
+ * Motherboards commonly drive two chip-select pins to
+ * a memory stick. A single-ranked stick, will occupy
+ * only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently.
+ *
+ * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
+ * A double-sided stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently. "Double-sided"
+ * is irrespective of the memory devices being mounted
+ * on both sides of the memory stick.
+ *
+ * Socket set: All of the memory sticks that are required for
+ * a single memory access or all of the memory sticks
+ * spanned by a chip-select row. A single socket set
+ * has two chip-select rows and if double-sided sticks
+ * are used these will occupy those chip-select rows.
+ *
+ * Bank: This term is avoided because it is unclear when
+ * needing to distinguish between chip-select rows and
+ * socket sets.
+ *
