+==========================================
+ARM idle states binding description
+==========================================
+
+==========================================
+1 - Introduction
+==========================================
+
+ARM systems contain HW capable of managing power consumption dynamically,
+where cores can be put in different low-power states (ranging from simple
+wfi to power gating) according to OS PM policies. The CPU states representing
+the range of dynamic idle states that a processor can enter at run-time, can be
+specified through device tree bindings representing the parameters required
+to enter/exit specific idle states on a given processor.
+
+According to the Server Base System Architecture document (SBSA, [3]), the
+power states an ARM CPU can be put into are identified by the following list:
+
+- Running
+- Idle_standby
+- Idle_retention
+- Sleep
+- Off
+
+The power states described in the SBSA document define the basic CPU states on
+top of which ARM platforms implement power management schemes that allow an OS
+PM implementation to put the processor in different idle states (which include
+states listed above; "off" state is not an idle state since it does not have
+wake-up capabilities, hence it is not considered in this document).
+
+Idle state parameters (eg entry latency) are platform specific and need to be
+characterized with bindings that provide the required information to OS PM
+code so that it can build the required tables and use them at runtime.
+
+The device tree binding definition for ARM idle states is the subject of this
+document.
+
+===========================================
+2 - idle-states definitions
+===========================================
+
+Idle states are characterized for a specific system through a set of
+timing and energy related properties, that underline the HW behaviour
+triggered upon idle states entry and exit.
+
+The following diagram depicts the CPU execution phases and related timing
+properties required to enter and exit an idle state:
+
+..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
+	    |          |           |          |          |
+
+	    |<------ entry ------->|
+	    |       latency        |
+					      |<- exit ->|
+					      |  latency |
+	    |<-------- min-residency -------->|
+		       |<-------  wakeup-latency ------->|
+
+		Diagram 1: CPU idle state execution phases
+
+EXEC:	Normal CPU execution.
+
+PREP:	Preparation phase before committing the hardware to idle mode
+	like cache flushing. This is abortable on pending wake-up
+	event conditions. The abort latency is assumed to be negligible
+	(i.e. less than the ENTRY + EXIT duration). If aborted, CPU
+	goes back to EXEC. This phase is optional. If not abortable,
+	this should be included in the ENTRY phase instead.
+
+ENTRY:	The hardware is committed to idle mode. This period must run
+	to completion up to IDLE before anything else can happen.
+
+IDLE:	This is the actual energy-saving idle period. This may last
+	between 0 and infinite time, until a wake-up event occurs.
+
+EXIT:	Period during which the CPU is brought back to operational
+	mode (EXEC).
+
+entry-latency: Worst case latency required to enter the idle state. The
+exit-latency may be guaranteed only after entry-latency has passed.
+
+min-residency: Minimum period, including preparation and entry, for a given
+idle state to be worthwhile energywise.
+
+wakeup-latency: Maximum delay between the signaling of a wake-up event and the
+CPU being able to execute normal code again. If not specified, this is assumed
+to be entry-latency + exit-latency.
+
+These timing parameters can be used by an OS in different circumstances.
+
+An idle CPU requires the expected min-residency time to select the most
+appropriate idle state based on the expected expiry time of the next IRQ
+(ie wake-up) that causes the CPU to return to the EXEC phase.
+
+An operating system scheduler may need to compute the shortest wake-up delay
+for CPUs in the system by detecting how long will it take to get a CPU out
+of an idle state, eg:
+
+wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
+
+In other words, the scheduler can make its scheduling decision by selecting
+(eg waking-up) the CPU with the shortest wake-up latency.
+The wake-up latency must take into account the entry latency if that period
+has not expired. The abortable nature of the PREP period can be ignored
+if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
+the worst case since it depends on the CPU operating conditions, ie caches
+state).
+
+An OS has to reliably probe the wakeup-latency since some devices can enforce
+latency constraints guarantees to work properly, so the OS has to detect the
+worst case wake-up latency it can incur if a CPU is allowed to enter an
+idle state, and possibly to prevent that to guarantee reliable device
+functioning.
+
+The min-residency time parameter deserves further explanation since it is
+expressed in time units but must factor in energy consumption coefficients.
+
+The energy consumption of a cpu when it enters a power state can be roughly
+characterised by the following graph:
+
+               |
+               |
+               |
+           e   |
+           n   |                                      /---

+
+		Graph 1: Energy vs time example
+
+The graph is split in two parts delimited by time 1ms on the X-axis.
+The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
+and denotes the energy costs incurred whilst entering and leaving the idle
+state.
+The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
+shallower slope and essentially represents the energy consumption of the idle
+state.
+
+min-residency is defined for a given idle state as the minimum expected
+residency time for a state (inclusive of preparation and entry) after
+which choosing that state become the most energy efficient option. A good
+way to visualise this, is by taking the same graph above and comparing some
+states energy consumptions plots.
+
+For sake of simplicity, let's consider a system with two idle states IDLE1,
+and IDLE2:
+
+          |
+          |
+          |
+          |                                                  /-- IDLE1

+          | /                          |
+          |/                           |                  time
+       ---/----------------------------+------------------------
+          |IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
+                                       |
+                                IDLE2-min-residency
+
+		Graph 2: idle states min-residency example
+
+In graph 2 above, that takes into account idle states entry/exit energy
+costs, it is clear that if the idle state residency time (ie time till next
+wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
+choice energywise.
+
+This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
+than IDLE2.
+
+However, the lower power consumption (ie shallower energy curve slope) of idle
+state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
+efficient.
+
+The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
+shallower states in a system with multiple idle states) is defined
+IDLE2-min-residency and corresponds to the time when energy consumption of
+IDLE1 and IDLE2 states breaks even.
+
+The definitions provided in this section underpin the idle states
+properties specification that is the subject of the following sections.

+	Description: idle-states node is a container node, where its
+		     subnodes describe the CPU idle states.
+
+	Node name must be "idle-states".
+
+	The idle-states node's parent node must be the cpus node.
+
+	The idle-states node's child nodes can be:
+
+	- one or more state nodes
+
+	Any other configuration is considered invalid.
+
+	An idle-states node defines the following properties:
+
+	- entry-method
+		Value type: <stringlist>
+		Usage and definition depend on ARM architecture version.
+			# On ARM v8 64-bit this property is required and must
+			  be one of:
+			   - "psci" (see bindings in [2])
+			# On ARM 32-bit systems this property is optional
+
+The nodes describing the idle states (state) can only be defined within the
+idle-states node, any other configuration is considered invalid and therefore
+must be ignored.
+
+===========================================
+4 - state node
+===========================================
+
+A state node represents an idle state description and must be defined as
+follows:
+
+- state node
+
+	Description: must be child of the idle-states node
+
+	The state node name shall follow standard device tree naming
+	rules ([5], 2.2.1 "Node names"), in particular state nodes which
+	are siblings within a single common parent must be given a unique name.
+
+	The idle state entered by executing the wfi instruction (idle_standby
+	SBSA,[3][4]) is considered standard on all ARM platforms and therefore
+	must not be listed.
+
+	With the definitions provided above, the following list represents
+	the valid properties for a state node:
+
+	- compatible
+		Usage: Required
+		Value type: <stringlist>
+		Definition: Must be "arm,idle-state".
+
+	- local-timer-stop
+		Usage: See definition
+		Value type: <none>
+		Definition: if present the CPU local timer control logic is
+			    lost on state entry, otherwise it is retained.
+
+	- entry-latency-us
+		Usage: Required
+		Value type: <prop-encoded-array>
+		Definition: u32 value representing worst case latency in
+			    microseconds required to enter the idle state.
+			    The exit-latency-us duration may be guaranteed
+			    only after entry-latency-us has passed.
+
+	- exit-latency-us
+		Usage: Required
+		Value type: <prop-encoded-array>
+		Definition: u32 value representing worst case latency
+			    in microseconds required to exit the idle state.
+
+	- min-residency-us
+		Usage: Required
+		Value type: <prop-encoded-array>
+		Definition: u32 value representing minimum residency duration
+			    in microseconds, inclusive of preparation and
+			    entry, for this idle state to be considered
+			    worthwhile energy wise (refer to section 2 of
+			    this document for a complete description).
+
+	- wakeup-latency-us:
+		Usage: Optional
+		Value type: <prop-encoded-array>
+		Definition: u32 value representing maximum delay between the
+			    signaling of a wake-up event and the CPU being
+			    able to execute normal code again. If omitted,
+			    this is assumed to be equal to:
+
+				entry-latency-us + exit-latency-us
+
+			    It is important to supply this value on systems
+			    where the duration of PREP phase (see diagram 1,
+			    section 2) is non-neglibigle.
+			    In such systems entry-latency-us + exit-latency-us
+			    will exceed wakeup-latency-us by this duration.
+
+	In addition to the properties listed above, a state node may require
+	additional properties specifics to the entry-method defined in the
+	idle-states node, please refer to the entry-method bindings
+	documentation for properties definitions.

+
+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.
+
+
+PIN CONFIGURATION NODES:
+
+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:
+	Usage: required
+	Value type: <string-array>
+	Definition: List of gpio pins affected by the properties specified in

+ST DWC3 glue logic
+
+This file documents the parameters for the dwc3-st driver.
+This driver controls the glue logic used to configure the dwc3 core on
+STiH407 based platforms.
+
+Required properties:
+ - compatible	: must be "st,stih407-dwc3"
+ - reg		: glue logic base address and USB syscfg ctrl register offset
+ - reg-names	: should be "reg-glue" and "syscfg-reg"
+ - st,syscon	: should be phandle to system configuration node which
+		  encompasses the glue registers
+ - resets	: list of phandle and reset specifier pairs. There should be two entries, one
+		  for the powerdown and softreset lines of the usb3 IP
+ - reset-names	: list of reset signal names. Names should be "powerdown" and "softreset"
+See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
+See: Documentation/devicetree/bindings/reset/reset.txt
+
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+   with 'reg' property
+
+ - pinctl-names	: A pinctrl state named "default" must be defined
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+ - pinctrl-0	: Pin control group
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+ - ranges	: allows valid 1:1 translation between child's address space and
+		  parent's address space
+
+Sub-nodes:
+The dwc3 core should be added as subnode to ST DWC3 glue as shown in the
+example below. The DT binding details of dwc3 can be found in:
+Documentation/devicetree/bindings/usb/dwc3.txt
+
+NB: The dr_mode property described in [1] is NOT optional for this driver, as the default value
+is "otg", which isn't supported by this SoC. Valid dr_mode values for dwc3-st are either "host"
+or "device".

+Open Firmware Device Tree Selftest
+----------------------------------
+
+Author: Gaurav Minocha <gaurav.minocha.os@gmail.com>
+
+1. Introduction
+
+This document explains how the test data required for executing OF selftest
+is attached to the live tree dynamically, independent of the machine's
+architecture.
+
+It is recommended to read the following documents before moving ahead.
+
+[1] Documentation/devicetree/usage-model.txt
+[2] http://www.devicetree.org/Device_Tree_Usage
+
+OF Selftest has been designed to test the interface (include/linux/of.h)
+provided to device driver developers to fetch the device information..etc.
+from the unflattened device tree data structure. This interface is used by
+most of the device drivers in various use cases.
+
+
+2. Test-data
+
+The Device Tree Source file (drivers/of/testcase-data/testcases.dts) contains
+the test data required for executing the unit tests automated in
+drivers/of/selftests.c. Currently, following Device Tree Source Include files
+(.dtsi) are included in testcase.dts:
+
+drivers/of/testcase-data/tests-interrupts.dtsi
+drivers/of/testcase-data/tests-platform.dtsi
+drivers/of/testcase-data/tests-phandle.dtsi
+drivers/of/testcase-data/tests-match.dtsi
+
+When the kernel is build with OF_SELFTEST enabled, then the following make rule
+
+$(obj)/%.dtb: $(src)/%.dts FORCE
+	$(call if_changed_dep, dtc)
+
+is used to compile the DT source file (testcase.dts) into a binary blob
+(testcase.dtb), also referred as flattened DT.
+
+After that, using the following rule the binary blob above is wrapped as an
+assembly file (testcase.dtb.S).
+
+$(obj)/%.dtb.S: $(obj)/%.dtb
+	$(call cmd, dt_S_dtb)
+
+The assembly file is compiled into an object file (testcase.dtb.o), and is
+linked into the kernel image.
+
+
+2.1. Adding the test data
+
+Un-flattened device tree structure:
+
+Un-flattened device tree consists of connected device_node(s) in form of a tree
+structure described below.
+
+// following struct members are used to construct the tree
+struct device_node {
+    ...
+    struct  device_node *parent;
+    struct  device_node *child;
+    struct  device_node *sibling;
+    struct  device_node *allnext;   /* next in list of all nodes */
+    ...
+ };
+
+Figure 1, describes a generic structure of machine’s un-flattened device tree
+considering only child and sibling pointers. There exists another pointer,
+*parent, that is used to traverse the tree in the reverse direction. So, at
+a particular level the child node and all the sibling nodes will have a parent
+pointer pointing to a common node (e.g. child1, sibling2, sibling3, sibling4’s
+parent points to root node)
+
+root (‘/’)
+   |
+child1 -> sibling2 -> sibling3 -> sibling4 -> null
+   |         |           |           |
+   |         |           |          null
+   |         |           |
+   |         |        child31 -> sibling32 -> null
+   |         |           |          |
+   |         |          null       null
+   |         |
+   |      child21 -> sibling22 -> sibling23 -> null
+   |         |          |            |
+   |        null       null         null
+   |
+child11 -> sibling12 -> sibling13 -> sibling14 -> null
+   |           |           |            |
+   |           |           |           null
+   |           |           |
+  null        null       child131 -> null
+                           |
+                          null
+
+Figure 1: Generic structure of un-flattened device tree
+
+
+*allnext: it is used to link all the nodes of DT into a list. So, for the
+ above tree the list would be as follows:
+
+root->child1->child11->sibling12->sibling13->child131->sibling14->sibling2->
+child21->sibling22->sibling23->sibling3->child31->sibling32->sibling4->null
+
+Before executing OF selftest, it is required to attach the test data to
+machine's device tree (if present). So, when selftest_data_add() is called,
+at first it reads the flattened device tree data linked into the kernel image
+via the following kernel symbols:
+
+__dtb_testcases_begin - address marking the start of test data blob
+__dtb_testcases_end   - address marking the end of test data blob
+
+Secondly, it calls of_fdt_unflatten_device_tree() to unflatten the flattened
+blob. And finally, if the machine’s device tree (i.e live tree) is present,
+then it attaches the unflattened test data tree to the live tree, else it
+attaches itself as a live device tree.
+
+attach_node_and_children() uses of_attach_node() to attach the nodes into the
+live tree as explained below. To explain the same, the test data tree described
+ in Figure 2 is attached to the live tree described in Figure 1.

+
+
+allnext list:
+
+root->testcase-data->test-child0->test-child01->test-sibling1->test-sibling2
+->test-sibling3->null
+
+Figure 2: Example test data tree to be attached to live tree.
+
+According to the scenario above, the live tree is already present so it isn’t
+required to attach the root(‘/’) node. All other nodes are attached by calling
+of_attach_node() on each node.
+
+In the function of_attach_node(), the new node is attached as the child of the
+given parent in live tree. But, if parent already has a child then the new node
+replaces the current child and turns it into its sibling. So, when the testcase
+data node is attached to the live tree above (Figure 1), the final structure is
+ as shown in Figure 3.

+Figure 3: Live device tree structure after attaching the testcase-data.
+
+
+Astute readers would have noticed that test-child0 node becomes the last
+sibling compared to the earlier structure (Figure 2). After attaching first
+test-child0 the test-sibling1 is attached that pushes the child node
+(i.e. test-child0) to become a sibling and makes itself a child node,
+ as mentioned above.
+
+If a duplicate node is found (i.e. if a node with same full_name property is
+already present in the live tree), then the node isn’t attached rather its
+properties are updated to the live tree’s node by calling the function
+update_node_properties().
+
+
+2.2. Removing the test data
+
+Once the test case execution is complete, selftest_data_remove is called in
+order to remove the device nodes attached initially (first the leaf nodes are
+detached and then moving up the parent nodes are removed, and eventually the
+whole tree). selftest_data_remove() calls detach_node_and_children() that uses
+of_detach_node() to detach the nodes from the live device tree.
+
+To detach a node, of_detach_node() first updates all_next linked list, by
+attaching the previous node’s allnext to current node’s allnext pointer. And
+then, it either updates the child pointer of given node’s parent to its
+sibling or attaches the previous sibling to the given node’s sibling, as
+appropriate. That is it :)

       UHID - User-space I/O driver support for HID subsystem
      ========================================================
 
-The HID subsystem needs two kinds of drivers. In this document we call them:
+UHID allows user-space to implement HID transport drivers. Please see
+hid-transport.txt for an introduction into HID transport drivers. This document
+relies heavily on the definitions declared there.
 
- 1. The "HID I/O Driver" is the driver that performs raw data I/O to the
-    low-level device. Internally, they register an hid_ll_driver structure with
-    the HID core. They perform device setup, read raw data from the device and
-    push it into the HID subsystem and they provide a callback so the HID
-    subsystem can send data to the device.
-
- 2. The "HID Device Driver" is the driver that parses HID reports and reacts on
-    them. There are generic drivers like "generic-usb" and "generic-bluetooth"
-    which adhere to the HID specification and provide the standardizes features.
-    But there may be special drivers and quirks for each non-standard device out
-    there. Internally, they use the hid_driver structure.
-
-Historically, the USB stack was the first subsystem to provide an HID I/O
-Driver. However, other standards like Bluetooth have adopted the HID specs and
-may provide HID I/O Drivers, too. The UHID driver allows to implement HID I/O
-Drivers in user-space and feed the data into the kernel HID-subsystem.
-
-This allows user-space to operate on the same level as USB-HID, Bluetooth-HID
-and similar. It does not provide a way to write HID Device Drivers, though. Use
-hidraw for this purpose.
+With UHID, a user-space transport driver can create kernel hid-devices for each
+device connected to the user-space controlled bus. The UHID API defines the I/O
+events provided from the kernel to user-space and vice versa.

+LZO stream format as understood by Linux's LZO decompressor
+===========================================================
+
+Introduction
+
+  This is not a specification. No specification seems to be publicly available
+  for the LZO stream format. This document describes what input format the LZO
+  decompressor as implemented in the Linux kernel understands. The file subject
+  of this analysis is lib/lzo/lzo1x_decompress_safe.c. No analysis was made on
+  the compressor nor on any other implementations though it seems likely that
+  the format matches the standard one. The purpose of this document is to
+  better understand what the code does in order to propose more efficient fixes
+  for future bug reports.
+
+Description
+
+  The stream is composed of a series of instructions, operands, and data. The
+  instructions consist in a few bits representing an opcode, and bits forming
+  the operands for the instruction, whose size and position depend on the
+  opcode and on the number of literals copied by previous instruction. The
+  operands are used to indicate :
+
+    - a distance when copying data from the dictionary (past output buffer)
+    - a length (number of bytes to copy from dictionary)
+    - the number of literals to copy, which is retained in variable "state"
+      as a piece of information for next instructions.
+
+  Optionally depending on the opcode and operands, extra data may follow. These
+  extra data can be a complement for the operand (eg: a length or a distance
+  encoded on larger values), or a literal to be copied to the output buffer.
+
+  The first byte of the block follows a different encoding from other bytes, it
+  seems to be optimized for literal use only, since there is no dictionary yet
+  prior to that byte.
+
+  Lengths are always encoded on a variable size starting with a small number
+  of bits in the operand. If the number of bits isn't enough to represent the
+  length, up to 255 may be added in increments by consuming more bytes with a
+  rate of at most 255 per extra byte (thus the compression ratio cannot exceed
+  around 255:1). The variable length encoding using #bits is always the same :
+
+       length = byte & ((1 << #bits) - 1)
+       if (!length) {
+               length = ((1 << #bits) - 1)
+               length += 255*(number of zero bytes)
+               length += first-non-zero-byte
+       }
+       length += constant (generally 2 or 3)
+
+  For references to the dictionary, distances are relative to the output
+  pointer. Distances are encoded using very few bits belonging to certain
+  ranges, resulting in multiple copy instructions using different encodings.
+  Certain encodings involve one extra byte, others involve two extra bytes
+  forming a little-endian 16-bit quantity (marked LE16 below).
+
+  After any instruction except the large literal copy, 0, 1, 2 or 3 literals
+  are copied before starting the next instruction. The number of literals that
+  were copied may change the meaning and behaviour of the next instruction. In
+  practice, only one instruction needs to know whether 0, less than 4, or more
+  literals were copied. This is the information stored in the <state> variable
+  in this implementation. This number of immediate literals to be copied is
+  generally encoded in the last two bits of the instruction but may also be
+  taken from the last two bits of an extra operand (eg: distance).
+
+  End of stream is declared when a block copy of distance 0 is seen. Only one
+  instruction may encode this distance (0001HLLL), it takes one LE16 operand
+  for the distance, thus requiring 3 bytes.
+
+  IMPORTANT NOTE : in the code some length checks are missing because certain
+  instructions are called under the assumption that a certain number of bytes
+  follow because it has already been garanteed before parsing the instructions.
+  They just have to "refill" this credit if they consume extra bytes. This is
+  an implementation design choice independant on the algorithm or encoding.
+
+Byte sequences
+
+  First byte encoding :
+
+      0..17   : follow regular instruction encoding, see below. It is worth
+                noting that codes 16 and 17 will represent a block copy from
+                the dictionary which is empty, and that they will always be
+                invalid at this place.
+
+      18..21  : copy 0..3 literals
+                state = (byte - 17) = 0..3  [ copy <state> literals ]
+                skip byte
+
+      22..255 : copy literal string
+                length = (byte - 17) = 4..238
+                state = 4 [ don't copy extra literals ]
+                skip byte
+
+  Instruction encoding :
+
+      0 0 0 0 X X X X  (0..15)
+        Depends on the number of literals copied by the last instruction.
+        If last instruction did not copy any literal (state == 0), this
+        encoding will be a copy of 4 or more literal, and must be interpreted
+        like this :
+
+           0 0 0 0 L L L L  (0..15)  : copy long literal string
+           length = 3 + (L ?: 15 + (zero_bytes * 255) + non_zero_byte)
+           state = 4  (no extra literals are copied)
+
+        If last instruction used to copy between 1 to 3 literals (encoded in
+        the instruction's opcode or distance), the instruction is a copy of a
+        2-byte block from the dictionary within a 1kB distance. It is worth
+        noting that this instruction provides little savings since it uses 2
+        bytes to encode a copy of 2 other bytes but it encodes the number of
+        following literals for free. It must be interpreted like this :
+
+           0 0 0 0 D D S S  (0..15)  : copy 2 bytes from <= 1kB distance
+           length = 2
+           state = S (copy S literals after this block)
+         Always followed by exactly one byte : H H H H H H H H
+           distance = (H << 2) + D + 1
+
+        If last instruction used to copy 4 or more literals (as detected by
+        state == 4), the instruction becomes a copy of a 3-byte block from the
+        dictionary from a 2..3kB distance, and must be interpreted like this :
+
+           0 0 0 0 D D S S  (0..15)  : copy 3 bytes from 2..3 kB distance
+           length = 3
+           state = S (copy S literals after this block)
+         Always followed by exactly one byte : H H H H H H H H

 Since only 19 bits are used to store generation-number on mmio spte, all
 pages are zapped when there is an overflow.
 
+Unfortunately, a single memory access might access kvm_memslots(kvm) multiple
+times, the last one happening when the generation number is retrieved and
+stored into the MMIO spte.  Thus, the MMIO spte might be created based on
+out-of-date information, but with an up-to-date generation number.
+
+To avoid this, the generation number is incremented again after synchronize_srcu
+returns; thus, the low bit of kvm_memslots(kvm)->generation is only 1 during a
+memslot update, while some SRCU readers might be using the old copy.  We do not
+want to use an MMIO sptes created with an odd generation number, and we can do
+this without losing a bit in the MMIO spte.  The low bit of the generation
+is not stored in MMIO spte, and presumed zero when it is extracted out of the
+spte.  If KVM is unlucky and creates an MMIO spte while the low bit is 1,
+the next access to the spte will always be a cache miss.

+ * 0xd0000000). The 0xf1000000 is the default used by the recent,
+ * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
+ * boards were delivered with an older version of the bootloader that
+ * left internal registers mapped at 0xd0000000. If you are in this
+ * situation, you should either update your bootloader (preferred
+ * solution) or the below Device Tree should be adjusted.

+	  syscalls, it's possible to isolate those applications in

+# RES_* macros take a name, a count and an optional alignment.
+# The count in in terms of the base size of the macro, and the
+# default alignment is the base size.
+# The macros are:
+# Macro    Base size
+# RES_B	    1
+# RES_W	    2
+# RES_D     4
+# RES_Q     8
+# RES_DQ   16
+# RES_Y    32
+# RES_Z    64
+#
+# RES_U defines a union. It's arguments are a name and two or more
+# pairs of "size, alignment"
+#
+# The two assigns are only needed if this structure is being nested
+# within another. Even if the assigns are not done, one can still use
+# STRUCT_NAME_size as the size of the structure.
+#
+# Note that for nesting, you still need to assign to STRUCT_NAME_size.
+#
+# The differences between this and using "struc" directly are that each
+# type is implicitly aligned to its natural length (although this can be
+# over-ridden with an explicit third parameter), and that the structure
+# is padded at the end to its overall alignment.

 	  a free irq and configures the IP. Thus the peripheral interrupts are
 	  routed to one of the free irqchip interrupt lines.

-Driver: amplc_pci224
-Description: Amplicon PCI224, PCI234
-Author: Ian Abbott <abbotti@mev.co.uk>
-Devices: [Amplicon] PCI224 (amplc_pci224 or pci224),
-  PCI234 (amplc_pci224 or pci234)
-Updated: Wed, 22 Oct 2008 12:25:08 +0100
-Status: works, but see caveats
-
-Supports:
-
-  - ao_insn read/write
-  - ao_do_cmd mode with the following sources:
-
-    - start_src         TRIG_INT        TRIG_EXT
-    - scan_begin_src    TRIG_TIMER      TRIG_EXT
-    - convert_src       TRIG_NOW
-    - scan_end_src      TRIG_COUNT
-    - stop_src          TRIG_COUNT      TRIG_EXT        TRIG_NONE
-
-    The channel list must contain at least one channel with no repeated
-    channels.  The scan end count must equal the number of channels in
-    the channel list.
-
-    There is only one external trigger source so only one of start_src,
-    scan_begin_src or stop_src may use TRIG_EXT.
-
-Configuration options - PCI224:
-  [0] - PCI bus of device (optional).
-  [1] - PCI slot of device (optional).
-          If bus/slot is not specified, the first available PCI device
-          will be used.
-  [2] - Select available ranges according to jumper LK1.  All channels
-        are set to the same range:
-        0=Jumper position 1-2 (factory default), 4 software-selectable
-          internal voltage references, giving 4 bipolar and 4 unipolar
-          ranges:
-            [-10V,+10V], [-5V,+5V], [-2.5V,+2.5V], [-1.25V,+1.25V],
-            [0,+10V], [0,+5V], [0,+2.5V], [0,1.25V].
-        1=Jumper position 2-3, 1 external voltage reference, giving
-          1 bipolar and 1 unipolar range:
-            [-Vext,+Vext], [0,+Vext].

-Configuration options - PCI234:
-  [0] - PCI bus of device (optional).
-  [1] - PCI slot of device (optional).
-          If bus/slot is not specified, the first available PCI device
-          will be used.
-  [2] - Select internal or external voltage reference according to
-        jumper LK1.  This affects all channels:
-        0=Jumper position 1-2 (factory default), Vref=5V internal.
-        1=Jumper position 2-3, Vref=Vext external.
-  [3] - Select channel 0 range according to jumper LK2:
-        0=Jumper position 2-3 (factory default), range [-2*Vref,+2*Vref]
-          (10V bipolar when options[2]=0).
-        1=Jumper position 1-2, range [-Vref,+Vref]
-          (5V bipolar when options[2]=0).
-  [4] - Select channel 1 range according to jumper LK3: cf. options[3].
-  [5] - Select channel 2 range according to jumper LK4: cf. options[3].
-  [6] - Select channel 3 range according to jumper LK5: cf. options[3].
-
-Passing a zero for an option is the same as leaving it unspecified.
-
-Caveats:
-
-  1) All channels on the PCI224 share the same range.  Any change to the
-     range as a result of insn_write or a streaming command will affect
-     the output voltages of all channels, including those not specified
-     by the instruction or command.
-
-  2) For the analog output command,  the first scan may be triggered
-     falsely at the start of acquisition.  This occurs when the DAC scan
-     trigger source is switched from 'none' to 'timer' (scan_begin_src =
-     TRIG_TIMER) or 'external' (scan_begin_src == TRIG_EXT) at the start
-     of acquisition and the trigger source is at logic level 1 at the
-     time of the switch.  This is very likely for TRIG_TIMER.  For
-     TRIG_EXT, it depends on the state of the external line and whether
-     the CR_INVERT flag has been set.  The remaining scans are triggered
-     correctly.

+ * Driver: amplc_pci224
+ * Description: Amplicon PCI224, PCI234
+ * Author: Ian Abbott <abbotti@mev.co.uk>
+ * Devices: [Amplicon] PCI224 (amplc_pci224), PCI234
+ * Updated: Thu, 31 Jul 2014 11:08:03 +0000
+ * Status: works, but see caveats
+ *
+ * Supports:
+ *
+ *   - ao_insn read/write
+ *   - ao_do_cmd mode with the following sources:
+ *
+ *     - start_src         TRIG_INT        TRIG_EXT
+ *     - scan_begin_src    TRIG_TIMER      TRIG_EXT
+ *     - convert_src       TRIG_NOW
+ *     - scan_end_src      TRIG_COUNT
+ *     - stop_src          TRIG_COUNT      TRIG_EXT        TRIG_NONE
+ *
+ *     The channel list must contain at least one channel with no repeated
+ *     channels.  The scan end count must equal the number of channels in
+ *     the channel list.
+ *
+ *     There is only one external trigger source so only one of start_src,
+ *     scan_begin_src or stop_src may use TRIG_EXT.
+ *
+ * Configuration options:
+ *   none
+ *
+ * Manual configuration of PCI cards is not supported; they are configured
+ * automatically.
+ *
+ * Output range selection - PCI224:
+ *
+ *   Output ranges on PCI224 are partly software-selectable and partly
+ *   hardware-selectable according to jumper LK1.  All channels are set
+ *   to the same range:
+ *
+ *   - LK1 position 1-2 (factory default) corresponds to the following
+ *     comedi ranges:
+ *
+ *       0: [-10V,+10V]; 1: [-5V,+5V]; 2: [-2.5V,+2.5V], 3: [-1.25V,+1.25V],
+ *       4: [0,+10V],    5: [0,+5V],   6: [0,+2.5V],     7: [0,+1.25V]
+ *
+ *   - LK1 position 2-3 corresponds to the following Comedi ranges, using
+ *     an external voltage reference:
+ *
+ *       0: [-Vext,+Vext],
+ *       1: [0,+Vext]
+ *
+ * Output range selection - PCI234:
+ *
+ *   Output ranges on PCI234 are hardware-selectable according to jumper
+ *   LK1 which affects all channels, and jumpers LK2, LK3, LK4 and LK5
+ *   which affect channels 0, 1, 2 and 3 individually.  LK1 chooses between
+ *   an internal 5V reference and an external voltage reference (Vext).
+ *   LK2/3/4/5 choose (per channel) to double the reference or not according
+ *   to the following table:
+ *
+ *     LK1 position   LK2/3/4/5 pos  Comedi range
+ *     -------------  -------------  --------------
+ *     2-3 (factory)  1-2 (factory)  0: [-10V,+10V]
+ *     2-3 (factory)  2-3            1: [-5V,+5V]
+ *     1-2            1-2 (factory)  2: [-2*Vext,+2*Vext]
+ *     1-2            2-3            3: [-Vext,+Vext]
+ *
+ * Caveats:
+ *
+ *   1) All channels on the PCI224 share the same range.  Any change to the
+ *      range as a result of insn_write or a streaming command will affect
+ *      the output voltages of all channels, including those not specified
+ *      by the instruction or command.
+ *
+ *   2) For the analog output command,  the first scan may be triggered
+ *      falsely at the start of acquisition.  This occurs when the DAC scan
+ *      trigger source is switched from 'none' to 'timer' (scan_begin_src =
+ *      TRIG_TIMER) or 'external' (scan_begin_src == TRIG_EXT) at the start
+ *      of acquisition and the trigger source is at logic level 1 at the
+ *      time of the switch.  This is very likely for TRIG_TIMER.  For
+ *      TRIG_EXT, it depends on the state of the external line and whether
+ *      the CR_INVERT flag has been set.  The remaining scans are triggered

+ * Every packet is at least 12 bytes long, here is the meaning of
+ * every field (all values are hex):
+ *
+ *	byte 0 is always 00
+ *	byte 1 is always 01
+ *	byte 2 is always 00
+ *	byte 3 is the total packet length
+ *
+ *	byte 4 is always 00
+ *	byte 5 is is the total packet length - 4
+ *	byte 6 is always 01
+ *	byte 7 is the command
+ *
+ *	byte 8 is 02 (request) or 00 (response)
+ *	byte 9 is 00 (response) or 10 (port request) or 20 (counter request)
+ *	byte 10 is always 00
+ *	byte 11 is 00 (request) or 02 (response)

- * The previous block comment is used to automatically generate
- * documentation in Comedi and Comedilib.  The fields:
- *
- *  Driver: the name of the driver
- *  Description: a short phrase describing the driver.  Don't list boards.
- *  Devices: a full list of the boards that attempt to be supported by
- *    the driver.  Format is "(manufacturer) board name [comedi name]",
- *    where comedi_name is the name that is used to configure the board.
- *    See the comment near board_name: in the struct comedi_driver structure
- *    below.  If (manufacturer) or [comedi name] is missing, the previous
- *    value is used.
- *  Author: you
- *  Updated: date when the _documentation_ was last updated.  Use 'date -R'
- *    to get a value for this.
- *  Status: a one-word description of the status.  Valid values are:
- *    works - driver works correctly on most boards supported, and
- *      passes comedi_test.
- *    unknown - unknown.  Usually put there by ds.
- *    experimental - may not work in any particular release.  Author
- *      probably wants assistance testing it.
- *    bitrotten - driver has not been update in a long time, probably
- *      doesn't work, and probably is missing support for significant
- *      Comedi interface features.
- *    untested - author probably wrote it "blind", and is believed to
- *      work, but no confirmation.
- *
- * These headers should be followed by a blank line, and any comments
- * you wish to say about the driver.  The comment area is the place
- * to put any known bugs, limitations, unsupported features, supported
- * command triggers, whether or not commands are supported on particular
- * subdevices, etc.
- *
- * Somewhere in the comment should be information about configuration
- * options that are used with comedi_config.

-This is a driver for the ET1310 network device.
-
-Based on the driver found at https://sourceforge.net/projects/et131x/
-
-Cleaned up immensely by Olaf Hartman and Christoph Hellwig <hch@infradead.org>
-
-Note, the powermanagement options were removed from the vendor provided
-driver as they did not build properly at the time.
-
-TODO:
-	- Look at reducing the number of spinlocks
-	- Simplify code in nic_rx_pkts(), when determining multicast_pkts_rcvd
-	- 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.
-
-Please send patches to:
-	Greg Kroah-Hartman <gregkh@linuxfoundation.org>
-	Mark Einon <mark.einon@gmail.com>

+Lustre Parallel Filesystem Client
+=================================
+
+The Lustre file system is an open-source, parallel file system
+that supports many requirements of leadership class HPC simulation
+environments.
+Born from from a research project at Carnegie Mellon University,
+the Lustre file system is a widely-used option in HPC.
+The Lustre file system provides a POSIX compliant file system interface,
+can scale to thousands of clients, petabytes of storage and
+hundreds of gigabytes per second of I/O bandwidth.
+
+Unlike shared disk storage cluster filesystems (e.g. OCFS2, GFS, GPFS),
+Lustre has independent Metadata and Data servers that clients can access
+in parallel to maximize performance.
+
+In order to use Lustre client you will need to download lustre client
+tools from
+https://downloads.hpdd.intel.com/public/lustre/latest-feature-release/
+the package name is lustre-client.
+
+You will need to install and configure your Lustre servers separately.
+
+Mount Syntax
+============
+After you installed the lustre-client tools including mount.lustre binary
+you can mount your Lustre filesystem with:
+
+mount -t lustre mgs:/fsname mnt
+
+where mgs is the host name or ip address of your Lustre MGS(management service)
+fsname is the name of the filesystem you would like to mount.
+
+
+Mount Options
+=============
+
+  noflock
+	Disable posix file locking (Applications trying to use
+	the functionality will get ENOSYS)
+
+  localflock
+	Enable local flock support, using only client-local flock
+	(faster, for applications that require flock but do not run
+	 on multiple nodes).
+
+  flock
+	Enable cluster-global posix file locking coherent across all
+	client nodes.
+
+  user_xattr, nouser_xattr
+	Support "user." extended attributes (or not)
+
+  user_fid2path, nouser_fid2path
+	Enable FID to path translation by regular users (or not)
+
+  checksum, nochecksum
+	Verify data consistency on the wire and in memory as it passes
+	between the layers (or not).
+
+  lruresize, nolruresize
+	Allow lock LRU to be controlled by memory pressure on the server
+	(or only 100 (default, controlled by lru_size proc parameter) locks
+	 per CPU per server on this client).
+
+  lazystatfs, nolazystatfs
+	Do not block in statfs() if some of the servers are down.
+
+  32bitapi
+	Shrink inode numbers to fit into 32 bits. This is necessary
+	if you plan to reexport Lustre filesystem from this client via
+	NFSv4.
+
+  verbose, noverbose
+	Enable mount/umount console messages (or not)
+
+More Information
+================
+You can get more information at
+OpenSFS website: http://lustre.opensfs.org/about/
+Intel HPDD wiki: https://wiki.hpdd.intel.com
+
+Out of tree Lustre client and server code is available at:
+http://git.whamcloud.com/fs/lustre-release.git

-/** \defgroup heap Binary heap
- *
- * The binary heap is a scalable data structure created using a binary tree. It
- * is capable of maintaining large sets of elements sorted usually by one or
- * more element properties, but really based on anything that can be used as a
- * binary predicate in order to determine the relevant ordering of any two nodes
- * that belong to the set. There is no search operation, rather the intention is
- * for the element of the lowest priority which will always be at the root of
- * the tree (as this is an implementation of a min-heap) to be removed by users
- * for consumption.
- *
- * Users of the heap should embed a \e cfs_binheap_node_t object instance on
- * every object of the set that they wish the binary heap instance to handle,
- * and (at a minimum) provide a cfs_binheap_ops_t::hop_compare() implementation
- * which is used by the heap as the binary predicate during its internal sorting
- * operations.
- *
- * The current implementation enforces no locking scheme, and so assumes the
- * user caters for locking between calls to insert, delete and lookup
- * operations. Since the only consumer for the data structure at this point
- * are NRS policies, and these operate on a per-CPT basis, binary heap instances
- * are tied to a specific CPT.

-Since none of these devices can function without having a valid

-TODO:
-- convert any remaining unusual variable types
-- find codes that can use %pM and %Nph formatting
-- checkpatch.pl fixes - most of the remaining ones are lines too long. Many
-  of them will require refactoring
-- merge Realtek's bugfixes and new features into the driver
-- Convert the versions of rtlwifi and btcoexist in drivers/net/wireless/rtlwifi/...
-  to work with the RTL8192EE
-- move this driver to drivers/net/wireless/rtlwifi
-
-Please send any patches to Greg Kroah-Hartman <gregkh@linux.com>,
-and Larry Finger <Larry.Finger@lwfinger.net>.
