/sys/bus/pci/slots/. The names of these directories are
specific to the driver, which in turn, are specific to the
platform, but in general, should match the label on the
machine's physical chassis.
The drivers that can create slot directories include the
PCI hotplug drivers, and as of 2.6.27, the pci_slot driver.
The slot directories contain, at a minimum, a file named
'address' which contains the PCI bus:device:function tuple.

Networking drivers must call dev_kfree_skb to free the socket buffer
and return NETDEV_TX_OK if the DMA mapping fails on the transmit hook
(ndo_start_xmit). This means that the socket buffer is just dropped in
the failure case.
SCSI drivers must return SCSI_MLQUEUE_HOST_BUSY if the DMA mapping
fails in the queuecommand hook. This means that the SCSI subsystem
passes the command to the driver again later.

of complex graphics devices, usually containing programmable
pipelines well suited to 3D graphics acceleration. Graphics
drivers in the kernel can make use of DRM functions to make
tasks like memory management, interrupt handling and DMA easier,
and provide a uniform interface to applications.

The DRM layer provides several services to graphics drivers,
many of them driven by the application interfaces it provides
through libdrm, the library that wraps most of the DRM ioctls.
These include vblank event handling, memory
management, output management, framebuffer management, command
submission &amp; fencing, suspend/resume support, and DMA
services.

In the example above, taken from the i915 DRM driver, the driver
sets several flags indicating what core features it supports.
We'll go over the individual callbacks in later sections. Since
flags indicate which features your driver supports to the DRM
core, you need to set most of them prior to calling drm_init(). Some,
like DRIVER_MODESET can be set later based on user supplied parameters,
but that's the exception rather than the rule.

In this specific case, the driver requires AGP and supports

in this case. It also supports the kernel mode setting APIs, though

exports KMS capability.
</para>
</sect1>
<!-- Internals: driver load -->
<sect1>
<title>Driver load</title>
<para>
In the previous section, we saw what a typical drm_driver
structure might look like. One of the more important fields in
the structure is the hook for the load function.
</para>
<programlisting>
static struct drm_driver driver = {
...
.load = i915_driver_load,
...
};
</programlisting>
<para>
The load function has many responsibilities: allocating a driver
private structure, specifying supported performance counters,
configuring the device (e.g. mapping registers &amp; command
buffers), initializing the memory manager, and setting up the
initial output configuration.
</para>
<para>
Note that the tasks performed at driver load time must not
conflict with DRM client requirements. For instance, if user
level mode setting drivers are in use, it would be problematic
to perform output discovery &amp; configuration at load time.
Likewise, if pre-memory management aware user level drivers are
in use, memory management and command buffer setup may need to
be omitted. These requirements are driver specific, and care
needs to be taken to keep both old and new applications and
libraries working. The i915 driver supports the "modeset"
module parameter to control whether advanced features are
enabled at load time or in legacy fashion. If compatibility is
a concern (e.g. with drivers converted over to the new interfaces
from the old ones), care must be taken to prevent incompatible
device initialization and control with the currently active
userspace drivers.
</para>
<sect2>
<title>Driver private &amp; performance counters</title>
<para>
The driver private hangs off the main drm_device structure and
can be used for tracking various device specific bits of
information, like register offsets, command buffer status,
register state for suspend/resume, etc. At load time, a
driver can simply allocate one and set drm_device.dev_priv
appropriately; at unload the driver can free it and set
drm_device.dev_priv to NULL.
</para>
<para>
The DRM supports several counters which can be used for rough
performance characterization. Note that the DRM stat counter
system is not often used by applications, and supporting
additional counters is completely optional.
</para>
<para>
These interfaces are deprecated and should not be used. If performance
monitoring is desired, the developer should investigate and
potentially enhance the kernel perf and tracing infrastructure to export
GPU related performance information to performance monitoring
tools and applications.

<title>Configuring the device</title>
<para>
Obviously, device configuration will be device specific.
However, there are several common operations: finding a
device's PCI resources, mapping them, and potentially setting
up an IRQ handler.
</para>
<para>
Finding &amp; mapping resources is fairly straightforward. The
DRM wrapper functions, drm_get_resource_start() and
drm_get_resource_len() can be used to find BARs on the given
drm_device struct. Once those values have been retrieved, the
driver load function can call drm_addmap() to create a new
mapping for the BAR in question. Note you'll probably want a
drm_local_map_t in your driver private structure to track any
mappings you create.
<!-- !Fdrivers/gpu/drm/drm_bufs.c drm_get_resource_* -->
<!-- !Finclude/drm/drmP.h drm_local_map_t -->
</para>
<para>
if compatibility with other operating systems isn't a concern
(DRM drivers can run under various BSD variants and OpenSolaris),
native Linux calls can be used for the above, e.g. pci_resource_*
and iomap*/iounmap. See the Linux device driver book for more
info.
</para>
<para>
Once you have a register map, you can use the DRM_READn() and
DRM_WRITEn() macros to access the registers on your device, or
use driver specific versions to offset into your MMIO space
relative to a driver specific base pointer (see I915_READ for
example).
</para>
<para>
If your device supports interrupt generation, you may want to
setup an interrupt handler at driver load time as well. This
is done using the drm_irq_install() function. If your device
supports vertical blank interrupts, it should call
drm_vblank_init() to initialize the core vblank handling code before
enabling interrupts on your device. This ensures the vblank related
structures are allocated and allows the core to handle vblank events.
</para>
<!--!Fdrivers/char/drm/drm_irq.c drm_irq_install-->
<para>
Once your interrupt handler is registered (it'll use your
drm_driver.irq_handler as the actual interrupt handling
function), you can safely enable interrupts on your device,
assuming any other state your interrupt handler uses is also
initialized.
</para>
<para>
Another task that may be necessary during configuration is
mapping the video BIOS. On many devices, the VBIOS describes
device configuration, LCD panel timings (if any), and contains
flags indicating device state. Mapping the BIOS can be done
using the pci_map_rom() call, a convenience function that
takes care of mapping the actual ROM, whether it has been
shadowed into memory (typically at address 0xc0000) or exists
on the PCI device in the ROM BAR. Note that once you've
mapped the ROM and extracted any necessary information, be
sure to unmap it; on many devices the ROM address decoder is
shared with other BARs, so leaving it mapped can cause
undesired behavior like hangs or memory corruption.
<!--!Fdrivers/pci/rom.c pci_map_rom-->
</para>
</sect2>
<sect2>
<title>Memory manager initialization</title>
<para>
In order to allocate command buffers, cursor memory, scanout
buffers, etc., as well as support the latest features provided
by packages like Mesa and the X.Org X server, your driver
should support a memory manager.
</para>
<para>
If your driver supports memory management (it should!), you'll
need to set that up at load time as well. How you intialize
it depends on which memory manager you're using, TTM or GEM.
</para>
<sect3>
<title>TTM initialization</title>
<para>
TTM (for Translation Table Manager) manages video memory and
aperture space for graphics devices. TTM supports both UMA devices
and devices with dedicated video RAM (VRAM), i.e. most discrete
graphics devices. If your device has dedicated RAM, supporting
TTM is desireable. TTM also integrates tightly with your
driver specific buffer execution function. See the radeon
driver for examples.
</para>
<para>
The core TTM structure is the ttm_bo_driver struct. It contains
several fields with function pointers for initializing the TTM,
allocating and freeing memory, waiting for command completion
and fence synchronization, and memory migration. See the
radeon_ttm.c file for an example of usage.
</para>
<para>
The ttm_global_reference structure is made up of several fields:
</para>
<programlisting>
struct ttm_global_reference {
enum ttm_global_types global_type;
size_t size;
void *object;
int (*init) (struct ttm_global_reference *);
void (*release) (struct ttm_global_reference *);
};
</programlisting>
<para>
There should be one global reference structure for your memory
manager as a whole, and there will be others for each object
created by the memory manager at runtime. Your global TTM should
have a type of TTM_GLOBAL_TTM_MEM. The size field for the global
object should be sizeof(struct ttm_mem_global), and the init and
release hooks should point at your driver specific init and
release routines, which will probably eventually call
ttm_mem_global_init and ttm_mem_global_release respectively.
</para>
<para>
Once your global TTM accounting structure is set up and initialized
(done by calling ttm_global_item_ref on the global object you
just created), you'll need to create a buffer object TTM to
provide a pool for buffer object allocation by clients and the
kernel itself. The type of this object should be TTM_GLOBAL_TTM_BO,
and its size should be sizeof(struct ttm_bo_global). Again,
driver specific init and release functions can be provided,
likely eventually calling ttm_bo_global_init and
ttm_bo_global_release, respectively. Also like the previous
object, ttm_global_item_ref is used to create an initial reference
count for the TTM, which will call your initalization function.
</para>
</sect3>
<sect3>
<title>GEM initialization</title>
<para>
GEM is an alternative to TTM, designed specifically for UMA
devices. It has simpler initialization and execution requirements
than TTM, but has no VRAM management capability. Core GEM
initialization is comprised of a basic drm_mm_init call to create
a GTT DRM MM object, which provides an address space pool for
object allocation. In a KMS configuration, the driver will
need to allocate and initialize a command ring buffer following
basic GEM initialization. Most UMA devices have a so-called
"stolen" memory region, which provides space for the initial
framebuffer and large, contiguous memory regions required by the
device. This space is not typically managed by GEM, and must
be initialized separately into its own DRM MM object.
</para>
<para>
Initialization will be driver specific, and will depend on
the architecture of the device. In the case of Intel
integrated graphics chips like 965GM, GEM initialization can
be done by calling the internal GEM init function,
i915_gem_do_init(). Since the 965GM is a UMA device
(i.e. it doesn't have dedicated VRAM), GEM will manage
making regular RAM available for GPU operations. Memory set
aside by the BIOS (called "stolen" memory by the i915
driver) will be managed by the DRM memrange allocator; the
rest of the aperture will be managed by GEM.
<programlisting>
/* Basic memrange allocator for stolen space (aka vram) */
drm_memrange_init(&amp;dev_priv->vram, 0, prealloc_size);
/* Let GEM Manage from end of prealloc space to end of aperture */
i915_gem_do_init(dev, prealloc_size, agp_size);
</programlisting>
<!--!Edrivers/char/drm/drm_memrange.c-->
</para>
<para>
Once the memory manager has been set up, we can allocate the
command buffer. In the i915 case, this is also done with a
GEM function, i915_gem_init_ringbuffer().
</para>
</sect3>
</sect2>
<sect2>
<title>Output configuration</title>
<para>
The final initialization task is output configuration. This involves
finding and initializing the CRTCs, encoders and connectors
for your device, creating an initial configuration and
registering a framebuffer console driver.
</para>
<sect3>
<title>Output discovery and initialization</title>
<para>
Several core functions exist to create CRTCs, encoders and
connectors, namely drm_crtc_init(), drm_connector_init() and
drm_encoder_init(), along with several "helper" functions to
perform common tasks.
</para>
<para>
Connectors should be registered with sysfs once they've been
detected and initialized, using the
drm_sysfs_connector_add() function. Likewise, when they're
removed from the system, they should be destroyed with
drm_sysfs_connector_remove().
</para>

</programlisting>
<para>
In the example above (again, taken from the i915 driver), a
CRT connector and encoder combination is created. A device
specific i2c bus is also created, for fetching EDID data and
performing monitor detection. Once the process is complete,
the new connector is regsitered with sysfs, to make its
properties available to applications.
</para>
<sect4>
<title>Helper functions and core functions</title>
<para>
Since many PC-class graphics devices have similar display output
designs, the DRM provides a set of helper functions to make
output management easier. The core helper routines handle
encoder re-routing and disabling of unused functions following
mode set. Using the helpers is optional, but recommended for
devices with PC-style architectures (i.e. a set of display planes
for feeding pixels to encoders which are in turn routed to
connectors). Devices with more complex requirements needing
finer grained management can opt to use the core callbacks
directly.
</para>
<para>
[Insert typical diagram here.] [Insert OMAP style config here.]
</para>
</sect4>
<para>
For each encoder, CRTC and connector, several functions must
be provided, depending on the object type. Encoder objects
need should provide a DPMS (basically on/off) function, mode fixup
(for converting requested modes into native hardware timings),
and prepare, set and commit functions for use by the core DRM
helper functions. Connector helpers need to provide mode fetch and
validity functions as well as an encoder matching function for
returing an ideal encoder for a given connector. The core
connector functions include a DPMS callback, (deprecated)
save/restore routines, detection, mode probing, property handling,
and cleanup functions.

<sect1>
<title>VBlank event handling</title>
<para>
The DRM core exposes two vertical blank related ioctls:
DRM_IOCTL_WAIT_VBLANK and DRM_IOCTL_MODESET_CTL.
<!--!Edrivers/char/drm/drm_irq.c-->
</para>
<para>
DRM_IOCTL_WAIT_VBLANK takes a struct drm_wait_vblank structure
as its argument, and is used to block or request a signal when a
specified vblank event occurs.
</para>
<para>
DRM_IOCTL_MODESET_CTL should be called by application level
drivers before and after mode setting, since on many devices the
vertical blank counter will be reset at that time. Internally,
the DRM snapshots the last vblank count when the ioctl is called
with the _DRM_PRE_MODESET command so that the counter won't go
backwards (which is dealt with when _DRM_POST_MODESET is used).
</para>
<para>
To support the functions above, the DRM core provides several
helper functions for tracking vertical blank counters, and
requires drivers to provide several callbacks:
get_vblank_counter(), enable_vblank() and disable_vblank(). The
core uses get_vblank_counter() to keep the counter accurate
across interrupt disable periods. It should return the current
vertical blank event count, which is often tracked in a device
register. The enable and disable vblank callbacks should enable
and disable vertical blank interrupts, respectively. In the
absence of DRM clients waiting on vblank events, the core DRM
code will use the disable_vblank() function to disable
interrupts, which saves power. They'll be re-enabled again when
a client calls the vblank wait ioctl above.
</para>
<para>
Devices that don't provide a count register can simply use an
internal atomic counter incremented on every vertical blank
interrupt, and can make their enable and disable vblank
functions into no-ops.
</para>
</sect1>
<sect1>
<title>Memory management</title>
<para>
The memory manager lies at the heart of many DRM operations, and
is also required to support advanced client features like OpenGL
pbuffers. The DRM currently contains two memory managers, TTM
and GEM.
</para>
<sect2>
<title>The Translation Table Manager (TTM)</title>
<para>
TTM was developed by Tungsten Graphics, primarily by Thomas
Hellström, and is intended to be a flexible, high performance
graphics memory manager.
</para>
<para>
Drivers wishing to support TTM must fill out a drm_bo_driver
structure.
</para>
<para>
TTM design background and information belongs here.
</para>
</sect2>
<sect2>
<title>The Graphics Execution Manager (GEM)</title>
<para>
GEM is an Intel project, authored by Eric Anholt and Keith
Packard. It provides simpler interfaces than TTM, and is well
suited for UMA devices.
</para>
<para>
GEM-enabled drivers must provide gem_init_object() and
gem_free_object() callbacks to support the core memory
allocation routines. They should also provide several driver
specific ioctls to support command execution, pinning, buffer
read &amp; write, mapping, and domain ownership transfers.
</para>
<para>
On a fundamental level, GEM involves several operations: memory
allocation and freeing, command execution, and aperture management
at command execution time. Buffer object allocation is relatively
straightforward and largely provided by Linux's shmem layer, which
provides memory to back each object. When mapped into the GTT
or used in a command buffer, the backing pages for an object are
flushed to memory and marked write combined so as to be coherent
with the GPU. Likewise, when the GPU finishes rendering to an object,
if the CPU accesses it, it must be made coherent with the CPU's view
of memory, usually involving GPU cache flushing of various kinds.
This core CPU&lt;-&gt;GPU coherency management is provided by the GEM
set domain function, which evaluates an object's current domain and
performs any necessary flushing or synchronization to put the object
into the desired coherency domain (note that the object may be busy,
i.e. an active render target; in that case the set domain function
will block the client and wait for rendering to complete before
performing any necessary flushing operations).
</para>
<para>
Perhaps the most important GEM function is providing a command
execution interface to clients. Client programs construct command
buffers containing references to previously allocated memory objects
and submit them to GEM. At that point, GEM will take care to bind
all the objects into the GTT, execute the buffer, and provide
necessary synchronization between clients accessing the same buffers.
This often involves evicting some objects from the GTT and re-binding
others (a fairly expensive operation), and providing relocation
support which hides fixed GTT offsets from clients. Clients must
take care not to submit command buffers that reference more objects
than can fit in the GTT or GEM will reject them and no rendering
will occur. Similarly, if several objects in the buffer require
fence registers to be allocated for correct rendering (e.g. 2D blits
on pre-965 chips), care must be taken not to require more fence
registers than are available to the client. Such resource management
should be abstracted from the client in libdrm.
</para>
</sect2>
</sect1>
<!-- Output management -->
<sect1>
<title>Output management</title>
<para>
At the core of the DRM output management code is a set of
structures representing CRTCs, encoders and connectors.
</para>
<para>
A CRTC is an abstraction representing a part of the chip that
contains a pointer to a scanout buffer. Therefore, the number
of CRTCs available determines how many independent scanout
buffers can be active at any given time. The CRTC structure
contains several fields to support this: a pointer to some video
memory, a display mode, and an (x, y) offset into the video
memory to support panning or configurations where one piece of
video memory spans multiple CRTCs.
</para>
<para>
An encoder takes pixel data from a CRTC and converts it to a
format suitable for any attached connectors. On some devices,
it may be possible to have a CRTC send data to more than one
encoder. In that case, both encoders would receive data from
the same scanout buffer, resulting in a "cloned" display
configuration across the connectors attached to each encoder.
</para>
<para>
A connector is the final destination for pixel data on a device,
and usually connects directly to an external display device like
a monitor or laptop panel. A connector can only be attached to
one encoder at a time. The connector is also the structure
where information about the attached display is kept, so it
contains fields for display data, EDID data, DPMS &amp;
connection status, and information about modes supported on the
attached displays.
</para>
<!--!Edrivers/char/drm/drm_crtc.c-->
</sect1>
<sect1>
<title>Framebuffer management</title>
<para>
In order to set a mode on a given CRTC, encoder and connector
configuration, clients need to provide a framebuffer object which
will provide a source of pixels for the CRTC to deliver to the encoder(s)
and ultimately the connector(s) in the configuration. A framebuffer
is fundamentally a driver specific memory object, made into an opaque
handle by the DRM addfb function. Once an fb has been created this
way it can be passed to the KMS mode setting routines for use in
a configuration.

The DRM core provides some suspend/resume code, but drivers
wanting full suspend/resume support should provide save() and

hibernate, or resume time, and should perform any state save or
restore required by your device across suspend or hibernate
states.

GPIOLIB conversion
------------------
If you need to convert your board or driver to use gpiolib from the exiting
s3c2410 api, then here are some notes on the process.
1) If your board is exclusively using an GPIO, say to control peripheral
power, then it will require to claim the gpio with gpio_request() before
it can use it.
It is recommended to check the return value, with at least WARN_ON()
during initialisation.
2) The s3c2410_gpio_cfgpin() can be directly replaced with s3c_gpio_cfgpin()
as they have the same arguments, and can either take the pin specific
values, or the more generic special-function-number arguments.
3) s3c2410_gpio_pullup() changs have the problem that whilst the
s3c2410_gpio_pullup(x, 1) can be easily translated to the
s3c_gpio_setpull(x, S3C_GPIO_PULL_NONE), the s3c2410_gpio_pullup(x, 0)
are not so easy.
The s3c2410_gpio_pullup(x, 0) case enables the pull-up (or in the case
of some of the devices, a pull-down) and as such the new API distinguishes
between the UP and DOWN case. There is currently no 'just turn on' setting
which may be required if this becomes a problem.
4) s3c2410_gpio_setpin() can be replaced by gpio_set_value(), the old call
does not implicitly configure the relevant gpio to output. The gpio
direction should be changed before using gpio_set_value().
5) s3c2410_gpio_getpin() is replaceable by gpio_get_value() if the pin
has been set to input. It is currently unknown what the behaviour is
when using gpio_get_value() on an output pin (s3c2410_gpio_getpin
would return the value the pin is supposed to be outputting).
6) s3c2410_gpio_getirq() should be directly replacable with the
gpio_to_irq() call.
The s3c2410_gpio and gpio_ calls have always operated on the same gpio
numberspace, so there is no problem with converting the gpio numbering
between the calls.

Samsung GPIO implementation
===========================
Introduction
------------
This outlines the Samsung GPIO implementation and the architecture
specfic calls provided alongisde the drivers/gpio core.
S3C24XX (Legacy)
----------------
See Documentation/arm/Samsung-S3C24XX/GPIO.txt for more information
about these devices. Their implementation is being brought into line
with the core samsung implementation described in this document.
GPIOLIB integration
-------------------
The gpio implementation uses gpiolib as much as possible, only providing
specific calls for the items that require Samsung specific handling, such
as pin special-function or pull resistor control.
GPIO numbering is synchronised between the Samsung and gpiolib system.
PIN configuration
-----------------
Pin configuration is specific to the Samsung architecutre, with each SoC
registering the necessary information for the core gpio configuration
implementation to configure pins as necessary.
The s3c_gpio_cfgpin() and s3c_gpio_setpull() provide the means for a
driver or machine to change gpio configuration.
See arch/arm/plat-samsung/include/plat/gpio-cfg.h for more information
on these functions.

so many different platform directories.
It was decided to remove plat-s5pc1xx as some of the support was already
in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210
the only user was the S5PC100. The S5PC100 specific items where moved to
arch/arm/mach-s5pc100.

3.7 Xattr table
---------------
The xattr table contains extended attributes for each inode. The xattrs
for each inode are stored in a list, each list entry containing a type,
name and value field. The type field encodes the xattr prefix
("user.", "trusted." etc) and it also encodes how the name/value fields
should be interpreted. Currently the type indicates whether the value
is stored inline (in which case the value field contains the xattr value),
or if it is stored out of line (in which case the value field stores a
reference to where the actual value is stored). This allows large values
to be stored out of line improving scanning and lookup performance and it
also allows values to be de-duplicated, the value being stored once, and
all other occurences holding an out of line reference to that value.
The xattr lists are packed into compressed 8K metadata blocks.
To reduce overhead in inodes, rather than storing the on-disk
location of the xattr list inside each inode, a 32-bit xattr id
is stored. This xattr id is mapped into the location of the xattr
list using a second xattr id lookup table.

Sysfs tagging
-------------
(Taken almost verbatim from Eric Biederman's netns tagging patch
commit msg)
The problem. Network devices show up in sysfs and with the network
namespace active multiple devices with the same name can show up in
the same directory, ouch!
To avoid that problem and allow existing applications in network
namespaces to see the same interface that is currently presented in
sysfs, sysfs now has tagging directory support.
By using the network namespace pointers as tags to separate out the
the sysfs directory entries we ensure that we don't have conflicts
in the directories and applications only see a limited set of
the network devices.
Each sysfs directory entry may be tagged with zero or one
namespaces. A sysfs_dirent is augmented with a void *s_ns. If a
directory entry is tagged, then sysfs_dirent->s_flags will have a

Each sysfs superblock's sysfs_super_info contains an array void

kobj_nstype first mounts sysfs, a new superblock is created. It
will be differentiated from other sysfs mounts by having its
s_fs_info->ns[kobj_nstype] set to the new namespace. Note that
through bind mounting and mounts propagation, a task can easily view
the contents of other namespaces' sysfs mounts. Therefore, when a
namespace exits, it will call kobj_ns_exit() to invalidate any
sysfs_dirent->s_ns pointers pointing to it.

XFS Delayed Logging Design
--------------------------
Introduction to Re-logging in XFS
---------------------------------
XFS logging is a combination of logical and physical logging. Some objects,
such as inodes and dquots, are logged in logical format where the details
logged are made up of the changes to in-core structures rather than on-disk
structures. Other objects - typically buffers - have their physical changes
logged. The reason for these differences is to reduce the amount of log space
required for objects that are frequently logged. Some parts of inodes are more
frequently logged than others, and inodes are typically more frequently logged
than any other object (except maybe the superblock buffer) so keeping the
amount of metadata logged low is of prime importance.
The reason that this is such a concern is that XFS allows multiple separate
modifications to a single object to be carried in the log at any given time.
This allows the log to avoid needing to flush each change to disk before
recording a new change to the object. XFS does this via a method called
"re-logging". Conceptually, this is quite simple - all it requires is that any
new change to the object is recorded with a *new copy* of all the existing
changes in the new transaction that is written to the log.
That is, if we have a sequence of changes A through to F, and the object was
written to disk after change D, we would see in the log the following series
of transactions, their contents and the log sequence number (LSN) of the
transaction:
Transaction Contents LSN
A A X
B A+B X+n
C A+B+C X+n+m
D A+B+C+D X+n+m+o
<object written to disk>
E E Y (> X+n+m+o)
F E+F Yٍ+p
In other words, each time an object is relogged, the new transaction contains
the aggregation of all the previous changes currently held only in the log.
This relogging technique also allows objects to be moved forward in the log so
that an object being relogged does not prevent the tail of the log from ever
moving forward. This can be seen in the table above by the changing
(increasing) LSN of each subsquent transaction - the LSN is effectively a
direct encoding of the location in the log of the transaction.
This relogging is also used to implement long-running, multiple-commit
transactions. These transaction are known as rolling transactions, and require
a special log reservation known as a permanent transaction reservation. A
typical example of a rolling transaction is the removal of extents from an
inode which can only be done at a rate of two extents per transaction because
of reservation size limitations. Hence a rolling extent removal transaction
keeps relogging the inode and btree buffers as they get modified in each
removal operation. This keeps them moving forward in the log as the operation
progresses, ensuring that current operation never gets blocked by itself if the
log wraps around.
Hence it can be seen that the relogging operation is fundamental to the correct
working of the XFS journalling subsystem. From the above description, most
people should be able to see why the XFS metadata operations writes so much to
the log - repeated operations to the same objects write the same changes to
the log over and over again. Worse is the fact that objects tend to get
dirtier as they get relogged, so each subsequent transaction is writing more
metadata into the log.
Another feature of the XFS transaction subsystem is that most transactions are
asynchronous. That is, they don't commit to disk until either a log buffer is
filled (a log buffer can hold multiple transactions) or a synchronous operation
forces the log buffers holding the transactions to disk. This means that XFS is
doing aggregation of transactions in memory - batching them, if you like - to
minimise the impact of the log IO on transaction throughput.
The limitation on asynchronous transaction throughput is the number and size of
log buffers made available by the log manager. By default there are 8 log
buffers available and the size of each is 32kB - the size can be increased up
to 256kB by use of a mount option.
Effectively, this gives us the maximum bound of outstanding metadata changes
that can be made to the filesystem at any point in time - if all the log
buffers are full and under IO, then no more transactions can be committed until
the current batch completes. It is now common for a single current CPU core to
be to able to issue enough transactions to keep the log buffers full and under
IO permanently. Hence the XFS journalling subsystem can be considered to be IO
bound.
Delayed Logging: Concepts
-------------------------
The key thing to note about the asynchronous logging combined with the
relogging technique XFS uses is that we can be relogging changed objects
multiple times before they are committed to disk in the log buffers. If we
return to the previous relogging example, it is entirely possible that
transactions A through D are committed to disk in the same log buffer.
That is, a single log buffer may contain multiple copies of the same object,
but only one of those copies needs to be there - the last one "D", as it
contains all the changes from the previous changes. In other words, we have one
necessary copy in the log buffer, and three stale copies that are simply
wasting space. When we are doing repeated operations on the same set of
objects, these "stale objects" can be over 90% of the space used in the log
buffers. It is clear that reducing the number of stale objects written to the
log would greatly reduce the amount of metadata we write to the log, and this
is the fundamental goal of delayed logging.
From a conceptual point of view, XFS is already doing relogging in memory (where
memory == log buffer), only it is doing it extremely inefficiently. It is using
logical to physical formatting to do the relogging because there is no
infrastructure to keep track of logical changes in memory prior to physically
formatting the changes in a transaction to the log buffer. Hence we cannot avoid
accumulating stale objects in the log buffers.
Delayed logging is the name we've given to keeping and tracking transactional
changes to objects in memory outside the log buffer infrastructure. Because of
the relogging concept fundamental to the XFS journalling subsystem, this is
actually relatively easy to do - all the changes to logged items are already
tracked in the current infrastructure. The big problem is how to accumulate
them and get them to the log in a consistent, recoverable manner.
Describing the problems and how they have been solved is the focus of this
document.
One of the key changes that delayed logging makes to the operation of the
journalling subsystem is that it disassociates the amount of outstanding
metadata changes from the size and number of log buffers available. In other
words, instead of there only being a maximum of 2MB of transaction changes not
written to the log at any point in time, there may be a much greater amount
being accumulated in memory. Hence the potential for loss of metadata on a
crash is much greater than for the existing logging mechanism.
It should be noted that this does not change the guarantee that log recovery
will result in a consistent filesystem. What it does mean is that as far as the
recovered filesystem is concerned, there may be many thousands of transactions
that simply did not occur as a result of the crash. This makes it even more
important that applications that care about their data use fsync() where they
need to ensure application level data integrity is maintained.
It should be noted that delayed logging is not an innovative new concept that
warrants rigorous proofs to determine whether it is correct or not. The method
of accumulating changes in memory for some period before writing them to the
log is used effectively in many filesystems including ext3 and ext4. Hence
no time is spent in this document trying to convince the reader that the
concept is sound. Instead it is simply considered a "solved problem" and as
such implementing it in XFS is purely an exercise in software engineering.
The fundamental requirements for delayed logging in XFS are simple:
1. Reduce the amount of metadata written to the log by at least
an order of magnitude.
2. Supply sufficient statistics to validate Requirement #1.
3. Supply sufficient new tracing infrastructure to be able to debug
problems with the new code.
4. No on-disk format change (metadata or log format).
5. Enable and disable with a mount option.
6. No performance regressions for synchronous transaction workloads.
Delayed Logging: Design
-----------------------
Storing Changes
The problem with accumulating changes at a logical level (i.e. just using the
existing log item dirty region tracking) is that when it comes to writing the
changes to the log buffers, we need to ensure that the object we are formatting
is not changing while we do this. This requires locking the object to prevent
concurrent modification. Hence flushing the logical changes to the log would
require us to lock every object, format them, and then unlock them again.
This introduces lots of scope for deadlocks with transactions that are already
running. For example, a transaction has object A locked and modified, but needs
the delayed logging tracking lock to commit the transaction. However, the
flushing thread has the delayed logging tracking lock already held, and is
trying to get the lock on object A to flush it to the log buffer. This appears
to be an unsolvable deadlock condition, and it was solving this problem that
was the barrier to implementing delayed logging for so long.
The solution is relatively simple - it just took a long time to recognise it.
Put simply, the current logging code formats the changes to each item into an
vector array that points to the changed regions in the item. The log write code
simply copies the memory these vectors point to into the log buffer during
transaction commit while the item is locked in the transaction. Instead of
using the log buffer as the destination of the formatting code, we can use an
allocated memory buffer big enough to fit the formatted vector.
If we then copy the vector into the memory buffer and rewrite the vector to
point to the memory buffer rather than the object itself, we now have a copy of
the changes in a format that is compatible with the log buffer writing code.
that does not require us to lock the item to access. This formatting and
rewriting can all be done while the object is locked during transaction commit,
resulting in a vector that is transactionally consistent and can be accessed
without needing to lock the owning item.
Hence we avoid the need to lock items when we need to flush outstanding
asynchronous transactions to the log. The differences between the existing
formatting method and the delayed logging formatting can be seen in the
diagram below.
Current format log vector:
Object +---------------------------------------------+
Vector 1 +----+
Vector 2 +----+
Vector 3 +----------+
After formatting:
Log Buffer +-V1-+-V2-+----V3----+
Delayed logging vector:
Object +---------------------------------------------+
Vector 1 +----+
Vector 2 +----+
Vector 3 +----------+
After formatting:
Memory Buffer +-V1-+-V2-+----V3----+
Vector 1 +----+
Vector 2 +----+
Vector 3 +----------+
The memory buffer and associated vector need to be passed as a single object,
but still need to be associated with the parent object so if the object is
relogged we can replace the current memory buffer with a new memory buffer that
contains the latest changes.
The reason for keeping the vector around after we've formatted the memory
buffer is to support splitting vectors across log buffer boundaries correctly.
If we don't keep the vector around, we do not know where the region boundaries
are in the item, so we'd need a new encapsulation method for regions in the log
buffer writing (i.e. double encapsulation). This would be an on-disk format
change and as such is not desirable. It also means we'd have to write the log
region headers in the formatting stage, which is problematic as there is per
region state that needs to be placed into the headers during the log write.
Hence we need to keep the vector, but by attaching the memory buffer to it and
rewriting the vector addresses to point at the memory buffer we end up with a
self-describing object that can be passed to the log buffer write code to be
handled in exactly the same manner as the existing log vectors are handled.
Hence we avoid needing a new on-disk format to handle items that have been
relogged in memory.
Tracking Changes
Now that we can record transactional changes in memory in a form that allows
them to be used without limitations, we need to be able to track and accumulate
them so that they can be written to the log at some later point in time. The
log item is the natural place to store this vector and buffer, and also makes sense
to be the object that is used to track committed objects as it will always
exist once the object has been included in a transaction.
The log item is already used to track the log items that have been written to
the log but not yet written to disk. Such log items are considered "active"
and as such are stored in the Active Item List (AIL) which is a LSN-ordered
double linked list. Items are inserted into this list during log buffer IO
completion, after which they are unpinned and can be written to disk. An object
that is in the AIL can be relogged, which causes the object to be pinned again
and then moved forward in the AIL when the log buffer IO completes for that
transaction.
Essentially, this shows that an item that is in the AIL can still be modified
and relogged, so any tracking must be separate to the AIL infrastructure. As
such, we cannot reuse the AIL list pointers for tracking committed items, nor
can we store state in any field that is protected by the AIL lock. Hence the
committed item tracking needs it's own locks, lists and state fields in the log
item.
Similar to the AIL, tracking of committed items is done through a new list
called the Committed Item List (CIL). The list tracks log items that have been
committed and have formatted memory buffers attached to them. It tracks objects
in transaction commit order, so when an object is relogged it is removed from
it's place in the list and re-inserted at the tail. This is entirely arbitrary
and done to make it easy for debugging - the last items in the list are the
ones that are most recently modified. Ordering of the CIL is not necessary for
transactional integrity (as discussed in the next section) so the ordering is
done for convenience/sanity of the developers.
Delayed Logging: Checkpoints
When we have a log synchronisation event, commonly known as a "log force",
all the items in the CIL must be written into the log via the log buffers.
We need to write these items in the order that they exist in the CIL, and they
need to be written as an atomic transaction. The need for all the objects to be
written as an atomic transaction comes from the requirements of relogging and
log replay - all the changes in all the objects in a given transaction must
either be completely replayed during log recovery, or not replayed at all. If
a transaction is not replayed because it is not complete in the log, then
no later transactions should be replayed, either.
To fulfill this requirement, we need to write the entire CIL in a single log
transaction. Fortunately, the XFS log code has no fixed limit on the size of a
transaction, nor does the log replay code. The only fundamental limit is that
the transaction cannot be larger than just under half the size of the log. The
reason for this limit is that to find the head and tail of the log, there must
be at least one complete transaction in the log at any given time. If a
transaction is larger than half the log, then there is the possibility that a
crash during the write of a such a transaction could partially overwrite the
only complete previous transaction in the log. This will result in a recovery
failure and an inconsistent filesystem and hence we must enforce the maximum
size of a checkpoint to be slightly less than a half the log.
Apart from this size requirement, a checkpoint transaction looks no different
to any other transaction - it contains a transaction header, a series of
formatted log items and a commit record at the tail. From a recovery
perspective, the checkpoint transaction is also no different - just a lot
bigger with a lot more items in it. The worst case effect of this is that we
might need to tune the recovery transaction object hash size.
Because the checkpoint is just another transaction and all the changes to log
items are stored as log vectors, we can use the existing log buffer writing
code to write the changes into the log. To do this efficiently, we need to
minimise the time we hold the CIL locked while writing the checkpoint
transaction. The current log write code enables us to do this easily with the
way it separates the writing of the transaction contents (the log vectors) from
the transaction commit record, but tracking this requires us to have a
per-checkpoint context that travels through the log write process through to
checkpoint completion.
Hence a checkpoint has a context that tracks the state of the current
checkpoint from initiation to checkpoint completion. A new context is initiated
at the same time a checkpoint transaction is started. That is, when we remove
all the current items from the CIL during a checkpoint operation, we move all
those changes into the current checkpoint context. We then initialise a new
context and attach that to the CIL for aggregation of new transactions.
This allows us to unlock the CIL immediately after transfer of all the
committed items and effectively allow new transactions to be issued while we
are formatting the checkpoint into the log. It also allows concurrent
checkpoints to be written into the log buffers in the case of log force heavy
workloads, just like the existing transaction commit code does. This, however,
requires that we strictly order the commit records in the log so that
checkpoint sequence order is maintained during log replay.
To ensure that we can be writing an item into a checkpoint transaction at
the same time another transaction modifies the item and inserts the log item
into the new CIL, then checkpoint transaction commit code cannot use log items
to store the list of log vectors that need to be written into the transaction.
Hence log vectors need to be able to be chained together to allow them to be
detatched from the log items. That is, when the CIL is flushed the memory
buffer and log vector attached to each log item needs to be attached to the
checkpoint context so that the log item can be released. In diagrammatic form,
the CIL would look like this before the flush:
CIL Head
|
V
Log Item <-> log vector 1 -> memory buffer
| -> vector array
V
Log Item <-> log vector 2 -> memory buffer
| -> vector array
V
......
|
V
Log Item <-> log vector N-1 -> memory buffer
| -> vector array
V
Log Item <-> log vector N -> memory buffer
-> vector array
And after the flush the CIL head is empty, and the checkpoint context log
vector list would look like:
Checkpoint Context
|
V
log vector 1 -> memory buffer
| -> vector array
| -> Log Item
V
log vector 2 -> memory buffer
| -> vector array
| -> Log Item
V
......
|
V
log vector N-1 -> memory buffer
| -> vector array
| -> Log Item
V
log vector N -> memory buffer
-> vector array
-> Log Item
Once this transfer is done, the CIL can be unlocked and new transactions can
start, while the checkpoint flush code works over the log vector chain to
commit the checkpoint.
Once the checkpoint is written into the log buffers, the checkpoint context is
attached to the log buffer that the commit record was written to along with a
completion callback. Log IO completion will call that callback, which can then
run transaction committed processing for the log items (i.e. insert into AIL
and unpin) in the log vector chain and then free the log vector chain and
checkpoint context.
Discussion Point: I am uncertain as to whether the log item is the most
efficient way to track vectors, even though it seems like the natural way to do
it. The fact that we walk the log items (in the CIL) just to chain the log
vectors and break the link between the log item and the log vector means that
we take a cache line hit for the log item list modification, then another for
the log vector chaining. If we track by the log vectors, then we only need to
break the link between the log item and the log vector, which means we should
dirty only the log item cachelines. Normally I wouldn't be concerned about one
vs two dirty cachelines except for the fact I've seen upwards of 80,000 log
vectors in one checkpoint transaction. I'd guess this is a "measure and
compare" situation that can be done after a working and reviewed implementation
is in the dev tree....
Delayed Logging: Checkpoint Sequencing
One of the key aspects of the XFS transaction subsystem is that it tags
committed transactions with the log sequence number of the transaction commit.
This allows transactions to be issued asynchronously even though there may be
future operations that cannot be completed until that transaction is fully
committed to the log. In the rare case that a dependent operation occurs (e.g.
re-using a freed metadata extent for a data extent), a special, optimised log
force can be issued to force the dependent transaction to disk immediately.
To do this, transactions need to record the LSN of the commit record of the
transaction. This LSN comes directly from the log buffer the transaction is
written into. While this works just fine for the existing transaction
mechanism, it does not work for delayed logging because transactions are not
written directly into the log buffers. Hence some other method of sequencing
transactions is required.
As discussed in the checkpoint section, delayed logging uses per-checkpoint
contexts, and as such it is simple to assign a sequence number to each
checkpoint. Because the switching of checkpoint contexts must be done
atomically, it is simple to ensure that each new context has a monotonically
increasing sequence number assigned to it without the need for an external
atomic counter - we can just take the current context sequence number and add
one to it for the new context.
Then, instead of assigning a log buffer LSN to the transaction commit LSN
during the commit, we can assign the current checkpoint sequence. This allows
operations that track transactions that have not yet completed know what
checkpoint sequence needs to be committed before they can continue. As a
result, the code that forces the log to a specific LSN now needs to ensure that
the log forces to a specific checkpoint.
To ensure that we can do this, we need to track all the checkpoint contexts
that are currently committing to the log. When we flush a checkpoint, the
context gets added to a "committing" list which can be searched. When a
checkpoint commit completes, it is removed from the committing list. Because
the checkpoint context records the LSN of the commit record for the checkpoint,
we can also wait on the log buffer that contains the commit record, thereby
using the existing log force mechanisms to execute synchronous forces.
It should be noted that the synchronous forces may need to be extended with
mitigation algorithms similar to the current log buffer code to allow
aggregation of multiple synchronous transactions if there are already
synchronous transactions being flushed. Investigation of the performance of the
current design is needed before making any decisions here.
The main concern with log forces is to ensure that all the previous checkpoints
are also committed to disk before the one we need to wait for. Therefore we
need to check that all the prior contexts in the committing list are also
complete before waiting on the one we need to complete. We do this
synchronisation in the log force code so that we don't need to wait anywhere
else for such serialisation - it only matters when we do a log force.
The only remaining complexity is that a log force now also has to handle the
case where the forcing sequence number is the same as the current context. That
is, we need to flush the CIL and potentially wait for it to complete. This is a
simple addition to the existing log forcing code to check the sequence numbers
and push if required. Indeed, placing the current sequence checkpoint flush in
the log force code enables the current mechanism for issuing synchronous
transactions to remain untouched (i.e. commit an asynchronous transaction, then
force the log at the LSN of that transaction) and so the higher level code
behaves the same regardless of whether delayed logging is being used or not.
Delayed Logging: Checkpoint Log Space Accounting
The big issue for a checkpoint transaction is the log space reservation for the
transaction. We don't know how big a checkpoint transaction is going to be
ahead of time, nor how many log buffers it will take to write out, nor the
number of split log vector regions are going to be used. We can track the
amount of log space required as we add items to the commit item list, but we
still need to reserve the space in the log for the checkpoint.
A typical transaction reserves enough space in the log for the worst case space
usage of the transaction. The reservation accounts for log record headers,
transaction and region headers, headers for split regions, buffer tail padding,
etc. as well as the actual space for all the changed metadata in the
transaction. While some of this is fixed overhead, much of it is dependent on
the size of the transaction and the number of regions being logged (the number
of log vectors in the transaction).
An example of the differences would be logging directory changes versus logging
inode changes. If you modify lots of inode cores (e.g. chmod -R g+w *), then
there are lots of transactions that only contain an inode core and an inode log
format structure. That is, two vectors totaling roughly 150 bytes. If we modify
10,000 inodes, we have about 1.5MB of metadata to write in 20,000 vectors. Each
vector is 12 bytes, so the total to be logged is approximately 1.75MB. In
comparison, if we are logging full directory buffers, they are typically 4KB
each, so we in 1.5MB of directory buffers we'd have roughly 400 buffers and a
buffer format structure for each buffer - roughly 800 vectors or 1.51MB total
space. From this, it should be obvious that a static log space reservation is
not particularly flexible and is difficult to select the "optimal value" for
all workloads.
Further, if we are going to use a static reservation, which bit of the entire
reservation does it cover? We account for space used by the transaction
reservation by tracking the space currently used by the object in the CIL and
then calculating the increase or decrease in space used as the object is
relogged. This allows for a checkpoint reservation to only have to account for
log buffer metadata used such as log header records.
However, even using a static reservation for just the log metadata is
problematic. Typically log record headers use at least 16KB of log space per
1MB of log space consumed (512 bytes per 32k) and the reservation needs to be
large enough to handle arbitrary sized checkpoint transactions. This
reservation needs to be made before the checkpoint is started, and we need to
be able to reserve the space without sleeping. For a 8MB checkpoint, we need a
reservation of around 150KB, which is a non-trivial amount of space.
A static reservation needs to manipulate the log grant counters - we can take a
permanent reservation on the space, but we still need to make sure we refresh
the write reservation (the actual space available to the transaction) after
every checkpoint transaction completion. Unfortunately, if this space is not
available when required, then the regrant code will sleep waiting for it.
The problem with this is that it can lead to deadlocks as we may need to commit
checkpoints to be able to free up log space (refer back to the description of
rolling transactions for an example of this). Hence we *must* always have
space available in the log if we are to use static reservations, and that is
very difficult and complex to arrange. It is possible to do, but there is a
simpler way.
The simpler way of doing this is tracking the entire log space used by the
items in the CIL and using this to dynamically calculate the amount of log
space required by the log metadata. If this log metadata space changes as a
result of a transaction commit inserting a new memory buffer into the CIL, then
the difference in space required is removed from the transaction that causes
the change. Transactions at this level will *always* have enough space
available in their reservation for this as they have already reserved the
maximal amount of log metadata space they require, and such a delta reservation
will always be less than or equal to the maximal amount in the reservation.
Hence we can grow the checkpoint transaction reservation dynamically as items
are added to the CIL and avoid the need for reserving and regranting log space
up front. This avoids deadlocks and removes a blocking point from the
checkpoint flush code.
As mentioned early, transactions can't grow to more than half the size of the
log. Hence as part of the reservation growing, we need to also check the size
of the reservation against the maximum allowed transaction size. If we reach
the maximum threshold, we need to push the CIL to the log. This is effectively
a "background flush" and is done on demand. This is identical to
a CIL push triggered by a log force, only that there is no waiting for the
checkpoint commit to complete. This background push is checked and executed by
transaction commit code.
If the transaction subsystem goes idle while we still have items in the CIL,
they will be flushed by the periodic log force issued by the xfssyncd. This log
force will push the CIL to disk, and if the transaction subsystem stays idle,
allow the idle log to be covered (effectively marked clean) in exactly the same
manner that is done for the existing logging method. A discussion point is
whether this log force needs to be done more frequently than the current rate
which is once every 30s.
Delayed Logging: Log Item Pinning
Currently log items are pinned during transaction commit while the items are
still locked. This happens just after the items are formatted, though it could
be done any time before the items are unlocked. The result of this mechanism is
that items get pinned once for every transaction that is committed to the log
buffers. Hence items that are relogged in the log buffers will have a pin count
for every outstanding transaction they were dirtied in. When each of these
transactions is completed, they will unpin the item once. As a result, the item
only becomes unpinned when all the transactions complete and there are no
pending transactions. Thus the pinning and unpinning of a log item is symmetric
as there is a 1:1 relationship with transaction commit and log item completion.
For delayed logging, however, we have an assymetric transaction commit to
completion relationship. Every time an object is relogged in the CIL it goes
through the commit process without a corresponding completion being registered.
That is, we now have a many-to-one relationship between transaction commit and
log item completion. The result of this is that pinning and unpinning of the
log items becomes unbalanced if we retain the "pin on transaction commit, unpin
on transaction completion" model.
To keep pin/unpin symmetry, the algorithm needs to change to a "pin on
insertion into the CIL, unpin on checkpoint completion". In other words, the
pinning and unpinning becomes symmetric around a checkpoint context. We have to
pin the object the first time it is inserted into the CIL - if it is already in
the CIL during a transaction commit, then we do not pin it again. Because there
can be multiple outstanding checkpoint contexts, we can still see elevated pin
counts, but as each checkpoint completes the pin count will retain the correct
value according to it's context.
Just to make matters more slightly more complex, this checkpoint level context
for the pin count means that the pinning of an item must take place under the
CIL commit/flush lock. If we pin the object outside this lock, we cannot
guarantee which context the pin count is associated with. This is because of
the fact pinning the item is dependent on whether the item is present in the
current CIL or not. If we don't pin the CIL first before we check and pin the
object, we have a race with CIL being flushed between the check and the pin
(or not pinning, as the case may be). Hence we must hold the CIL flush/commit
lock to guarantee that we pin the items correctly.
Delayed Logging: Concurrent Scalability
A fundamental requirement for the CIL is that accesses through transaction
commits must scale to many concurrent commits. The current transaction commit
code does not break down even when there are transactions coming from 2048
processors at once. The current transaction code does not go any faster than if
there was only one CPU using it, but it does not slow down either.
As a result, the delayed logging transaction commit code needs to be designed
for concurrency from the ground up. It is obvious that there are serialisation
points in the design - the three important ones are:
1. Locking out new transaction commits while flushing the CIL
2. Adding items to the CIL and updating item space accounting
3. Checkpoint commit ordering
Looking at the transaction commit and CIL flushing interactions, it is clear
that we have a many-to-one interaction here. That is, the only restriction on
the number of concurrent transactions that can be trying to commit at once is
the amount of space available in the log for their reservations. The practical
limit here is in the order of several hundred concurrent transactions for a
128MB log, which means that it is generally one per CPU in a machine.
The amount of time a transaction commit needs to hold out a flush is a
relatively long period of time - the pinning of log items needs to be done
while we are holding out a CIL flush, so at the moment that means it is held
across the formatting of the objects into memory buffers (i.e. while memcpy()s
are in progress). Ultimately a two pass algorithm where the formatting is done
separately to the pinning of objects could be used to reduce the hold time of
the transaction commit side.
Because of the number of potential transaction commit side holders, the lock
really needs to be a sleeping lock - if the CIL flush takes the lock, we do not
want every other CPU in the machine spinning on the CIL lock. Given that
flushing the CIL could involve walking a list of tens of thousands of log
items, it will get held for a significant time and so spin contention is a
significant concern. Preventing lots of CPUs spinning doing nothing is the
main reason for choosing a sleeping lock even though nothing in either the
transaction commit or CIL flush side sleeps with the lock held.
It should also be noted that CIL flushing is also a relatively rare operation
compared to transaction commit for asynchronous transaction workloads - only
time will tell if using a read-write semaphore for exclusion will limit
transaction commit concurrency due to cache line bouncing of the lock on the
read side.
The second serialisation point is on the transaction commit side where items
are inserted into the CIL. Because transactions can enter this code
concurrently, the CIL needs to be protected separately from the above
commit/flush exclusion. It also needs to be an exclusive lock but it is only
held for a very short time and so a spin lock is appropriate here. It is
possible that this lock will become a contention point, but given the short
hold time once per transaction I think that contention is unlikely.
The final serialisation point is the checkpoint commit record ordering code
that is run as part of the checkpoint commit and log force sequencing. The code
path that triggers a CIL flush (i.e. whatever triggers the log force) will enter
an ordering loop after writing all the log vectors into the log buffers but
before writing the commit record. This loop walks the list of committing
checkpoints and needs to block waiting for checkpoints to complete their commit
record write. As a result it needs a lock and a wait variable. Log force
sequencing also requires the same lock, list walk, and blocking mechanism to
ensure completion of checkpoints.
These two sequencing operations can use the mechanism even though the
events they are waiting for are different. The checkpoint commit record
sequencing needs to wait until checkpoint contexts contain a commit LSN
(obtained through completion of a commit record write) while log force
sequencing needs to wait until previous checkpoint contexts are removed from
the committing list (i.e. they've completed). A simple wait variable and
broadcast wakeups (thundering herds) has been used to implement these two
serialisation queues. They use the same lock as the CIL, too. If we see too
much contention on the CIL lock, or too many context switches as a result of
the broadcast wakeups these operations can be put under a new spinlock and
given separate wait lists to reduce lock contention and the number of processes
woken by the wrong event.
Lifecycle Changes
The existing log item life cycle is as follows:
1. Transaction allocate
2. Transaction reserve
3. Lock item
4. Join item to transaction
If not already attached,
Allocate log item
Attach log item to owner item
Attach log item to transaction
5. Modify item
Record modifications in log item
6. Transaction commit
Pin item in memory
Format item into log buffer
Write commit LSN into transaction
Unlock item
Attach transaction to log buffer
<log buffer IO dispatched>
<log buffer IO completes>
7. Transaction completion
Mark log item committed
Insert log item into AIL
Write commit LSN into log item
Unpin log item
8. AIL traversal
Lock item
Mark log item clean
Flush item to disk
<item IO completion>
9. Log item removed from AIL
Moves log tail
Item unlocked
Essentially, steps 1-6 operate independently from step 7, which is also
independent of steps 8-9. An item can be locked in steps 1-6 or steps 8-9
at the same time step 7 is occurring, but only steps 1-6 or 8-9 can occur
at the same time. If the log item is in the AIL or between steps 6 and 7
and steps 1-6 are re-entered, then the item is relogged. Only when steps 8-9
are entered and completed is the object considered clean.
With delayed logging, there are new steps inserted into the life cycle:
1. Transaction allocate
2. Transaction reserve
3. Lock item
4. Join item to transaction
If not already attached,
Allocate log item
Attach log item to owner item
Attach log item to transaction
5. Modify item
Record modifications in log item
6. Transaction commit
Pin item in memory if not pinned in CIL
Format item into log vector + buffer
Attach log vector and buffer to log item
Insert log item into CIL
Write CIL context sequence into transaction
Unlock item
<next log force>
7. CIL push
lock CIL flush
Chain log vectors and buffers together
Remove items from CIL
unlock CIL flush
write log vectors into log
sequence commit records
attach checkpoint context to log buffer
<log buffer IO dispatched>
<log buffer IO completes>
8. Checkpoint completion
Mark log item committed
Insert item into AIL
Write commit LSN into log item
Unpin log item
9. AIL traversal
Lock item
Mark log item clean
Flush item to disk
<item IO completion>
10. Log item removed from AIL
Moves log tail
Item unlocked
From this, it can be seen that the only life cycle differences between the two
logging methods are in the middle of the life cycle - they still have the same
beginning and end and execution constraints. The only differences are in the
commiting of the log items to the log itself and the completion processing.
Hence delayed logging should not introduce any constraints on log item
behaviour, allocation or freeing that don't already exist.
As a result of this zero-impact "insertion" of delayed logging infrastructure
and the design of the internal structures to avoid on disk format changes, we
can basically switch between delayed logging and the existing mechanism with a
mount option. Fundamentally, there is no reason why the log manager would not
be able to swap methods automatically and transparently depending on load
characteristics, but this should not be necessary if delayed logging works as
designed.
Roadmap:
2.6.35 Inclusion in mainline as an experimental mount option
=> approximately 2-3 months to merge window
=> needs to be in xfs-dev tree in 4-6 weeks
=> code is nearing readiness for review
2.6.37 Remove experimental tag from mount option
=> should be roughly 6 months after initial merge
=> enough time to:
=> gain confidence and fix problems reported by early
adopters (a.k.a. guinea pigs)
=> address worst performance regressions and undesired
behaviours
=> start tuning/optimising code for parallelism
=> start tuning/optimising algorithms consuming
excessive CPU time
2.6.39 Switch default mount option to use delayed logging
=> should be roughly 12 months after initial merge
=> enough time to shake out remaining problems before next round of
enterprise distro kernel rebases

The called party number provided by an application for dialing out must
be a public network number according to the local dialing plan, without
any dial prefix for getting an outside line.
Internal calls can be made by providing an internal extension number
prefixed with "**" (two asterisks) as the called party number. So to dial
eg. the first registered DECT handset, give "**11" as the called party
number. Dialing "***" (three asterisks) calls all extensions
simultaneously (global call).
This holds for both CAPI 2.0 and ISDN4Linux applications. Unimodem mode

/* for kvm_memory_region::flags */
#define KVM_MEM_LOG_DIRTY_PAGES 1UL
This ioctl allows the user to create or modify a guest physical memory
slot. When changing an existing slot, it may be moved in the guest
physical memory space, or its flags may be modified. It may not be
resized. Slots may not overlap in guest physical address space.
Memory for the region is taken starting at the address denoted by the
field userspace_addr, which must point at user addressable memory for
the entire memory slot size. Any object may back this memory, including
anonymous memory, ordinary files, and hugetlbfs.
It is recommended that the lower 21 bits of guest_phys_addr and userspace_addr
be identical. This allows large pages in the guest to be backed by large
pages in the host.
The flags field supports just one flag, KVM_MEM_LOG_DIRTY_PAGES, which
instructs kvm to keep track of writes to memory within the slot. See
the KVM_GET_DIRTY_LOG ioctl.
When the KVM_CAP_SYNC_MMU capability, changes in the backing of the memory
region are automatically reflected into the guest. For example, an mmap()
that affects the region will be made visible immediately. Another example
is madvise(MADV_DROP).
It is recommended to use this API instead of the KVM_SET_MEMORY_REGION ioctl.
The KVM_SET_MEMORY_REGION does not allow fine grained control over memory
allocation and is deprecated.

This ioctl defines the physical address of a three-page region in the guest
physical address space. The region must be within the first 4GB of the
guest physical address space and must not conflict with any memory slot
or any mmio address. The guest may malfunction if it accesses this memory

The x86 kvm shadow mmu
======================
The mmu (in arch/x86/kvm, files mmu.[ch] and paging_tmpl.h) is responsible
for presenting a standard x86 mmu to the guest, while translating guest
physical addresses to host physical addresses.
The mmu code attempts to satisfy the following requirements:
- correctness: the guest should not be able to determine that it is running
on an emulated mmu except for timing (we attempt to comply
with the specification, not emulate the characteristics of
a particular implementation such as tlb size)
- security: the guest must not be able to touch host memory not assigned
to it
- performance: minimize the performance penalty imposed by the mmu
- scaling: need to scale to large memory and large vcpu guests
- hardware: support the full range of x86 virtualization hardware
- integration: Linux memory management code must be in control of guest memory
so that swapping, page migration, page merging, transparent
hugepages, and similar features work without change
- dirty tracking: report writes to guest memory to enable live migration
and framebuffer-based displays
- footprint: keep the amount of pinned kernel memory low (most memory
should be shrinkable)
- reliablity: avoid multipage or GFP_ATOMIC allocations

Virtual and real hardware supported
===================================
The mmu supports first-generation mmu hardware, which allows an atomic switch
of the current paging mode and cr3 during guest entry, as well as
two-dimensional paging (AMD's NPT and Intel's EPT). The emulated hardware
it exposes is the traditional 2/3/4 level x86 mmu, with support for global
pages, pae, pse, pse36, cr0.wp, and 1GB pages. Work is in progress to support
exposing NPT capable hardware on NPT capable hosts.
Translation
===========
The primary job of the mmu is to program the processor's mmu to translate
addresses for the guest. Different translations are required at different
times:
- when guest paging is disabled, we translate guest physical addresses to
host physical addresses (gpa->hpa)
- when guest paging is enabled, we translate guest virtual addresses, to
guest physical addresses, to host physical addresses (gva->gpa->hpa)
- when the guest launches a guest of its own, we translate nested guest
virtual addresses, to nested guest physical addresses, to guest physical
addresses, to host physical addresses (ngva->ngpa->gpa->hpa)
The primary challenge is to encode between 1 and 3 translations into hardware
that support only 1 (traditional) and 2 (tdp) translations. When the
number of required translations matches the hardware, the mmu operates in
direct mode; otherwise it operates in shadow mode (see below).
Memory
======
Guest memory (gpa) is part of the user address space of the process that is
using kvm. Userspace defines the translation between guest addresses and user
addresses (gpa->hva); note that two gpas may alias to the same gva, but not
vice versa.
These gvas may be backed using any method available to the host: anonymous
memory, file backed memory, and device memory. Memory might be paged by the
host at any time.
Events
======
The mmu is driven by events, some from the guest, some from the host.
Guest generated events:
- writes to control registers (especially cr3)
- invlpg/invlpga instruction execution
- access to missing or protected translations
Host generated events:
- changes in the gpa->hpa translation (either through gpa->hva changes or
through hva->hpa changes)
- memory pressure (the shrinker)
Shadow pages
============
The principal data structure is the shadow page, 'struct kvm_mmu_page'. A
shadow page contains 512 sptes, which can be either leaf or nonleaf sptes. A
shadow page may contain a mix of leaf and nonleaf sptes.
A nonleaf spte allows the hardware mmu to reach the leaf pages and
is not related to a translation directly. It points to other shadow pages.
A leaf spte corresponds to either one or two translations encoded into
one paging structure entry. These are always the lowest level of the
translation stack, with optional higher level translations left to NPT/EPT.
Leaf ptes point at guest pages.
The following table shows translations encoded by leaf ptes, with higher-level
translations in parentheses:
Non-nested guests:
nonpaging: gpa->hpa
paging: gva->gpa->hpa
paging, tdp: (gva->)gpa->hpa
Nested guests:
non-tdp: ngva->gpa->hpa (*)
tdp: (ngva->)ngpa->gpa->hpa
(*) the guest hypervisor will encode the ngva->gpa translation into its page
tables if npt is not present
Shadow pages contain the following information:
role.level:
The level in the shadow paging hierarchy that this shadow page belongs to.
1=4k sptes, 2=2M sptes, 3=1G sptes, etc.
role.direct:
If set, leaf sptes reachable from this page are for a linear range.
Examples include real mode translation, large guest pages backed by small
host pages, and gpa->hpa translations when NPT or EPT is active.
The linear range starts at (gfn << PAGE_SHIFT) and its size is determined
by role.level (2MB for first level, 1GB for second level, 0.5TB for third
level, 256TB for fourth level)
If clear, this page corresponds to a guest page table denoted by the gfn
field.
role.quadrant:
When role.cr4_pae=0, the guest uses 32-bit gptes while the host uses 64-bit
sptes. That means a guest page table contains more ptes than the host,
so multiple shadow pages are needed to shadow one guest page.
For first-level shadow pages, role.quadrant can be 0 or 1 and denotes the
first or second 512-gpte block in the guest page table. For second-level
page tables, each 32-bit gpte is converted to two 64-bit sptes
(since each first-level guest page is shadowed by two first-level
shadow pages) so role.quadrant takes values in the range 0..3. Each
quadrant maps 1GB virtual address space.
role.access:
Inherited guest access permissions in the form uwx. Note execute
permission is positive, not negative.
role.invalid:
The page is invalid and should not be used. It is a root page that is
currently pinned (by a cpu hardware register pointing to it); once it is
unpinned it will be destroyed.
role.cr4_pae:
Contains the value of cr4.pae for which the page is valid (e.g. whether
32-bit or 64-bit gptes are in use).
role.cr4_nxe:
Contains the value of efer.nxe for which the page is valid.
role.cr0_wp:
Contains the value of cr0.wp for which the page is valid.
gfn:
Either the guest page table containing the translations shadowed by this
page, or the base page frame for linear translations. See role.direct.
spt:
A pageful of 64-bit sptes containing the translations for this page.
Accessed by both kvm and hardware.
The page pointed to by spt will have its page->private pointing back
at the shadow page structure.
sptes in spt point either at guest pages, or at lower-level shadow pages.
Specifically, if sp1 and sp2 are shadow pages, then sp1->spt[n] may point
at __pa(sp2->spt). sp2 will point back at sp1 through parent_pte.
The spt array forms a DAG structure with the shadow page as a node, and
guest pages as leaves.
gfns:
An array of 512 guest frame numbers, one for each present pte. Used to
perform a reverse map from a pte to a gfn.
slot_bitmap:
A bitmap containing one bit per memory slot. If the page contains a pte
mapping a page from memory slot n, then bit n of slot_bitmap will be set
(if a page is aliased among several slots, then it is not guaranteed that
all slots will be marked).
Used during dirty logging to avoid scanning a shadow page if none if its
pages need tracking.
root_count:
A counter keeping track of how many hardware registers (guest cr3 or
pdptrs) are now pointing at the page. While this counter is nonzero, the
page cannot be destroyed. See role.invalid.
multimapped:
Whether there exist multiple sptes pointing at this page.
parent_pte/parent_ptes:
If multimapped is zero, parent_pte points at the single spte that points at
this page's spt. Otherwise, parent_ptes points at a data structure
with a list of parent_ptes.
unsync:
If true, then the translations in this page may not match the guest's
translation. This is equivalent to the state of the tlb when a pte is
changed but before the tlb entry is flushed. Accordingly, unsync ptes
are synchronized when the guest executes invlpg or flushes its tlb by
other means. Valid for leaf pages.
unsync_children:
How many sptes in the page point at pages that are unsync (or have
unsynchronized children).
unsync_child_bitmap:
A bitmap indicating which sptes in spt point (directly or indirectly) at
pages that may be unsynchronized. Used to quickly locate all unsychronized
pages reachable from a given page.
Reverse map
===========
The mmu maintains a reverse mapping whereby all ptes mapping a page can be
reached given its gfn. This is used, for example, when swapping out a page.
Synchronized and unsynchronized pages
=====================================
The guest uses two events to synchronize its tlb and page tables: tlb flushes
and page invalidations (invlpg).
A tlb flush means that we need to synchronize all sptes reachable from the
guest's cr3. This is expensive, so we keep all guest page tables write
protected, and synchronize sptes to gptes when a gpte is written.
A special case is when a guest page table is reachable from the current
guest cr3. In this case, the guest is obliged to issue an invlpg instruction
before using the translation. We take advantage of that by removing write
protection from the guest page, and allowing the guest to modify it freely.
We synchronize modified gptes when the guest invokes invlpg. This reduces
the amount of emulation we have to do when the guest modifies multiple gptes,
or when the a guest page is no longer used as a page table and is used for
random guest data.
As a side effect we have to resynchronize all reachable unsynchronized shadow
pages on a tlb flush.
Reaction to events
==================
- guest page fault (or npt page fault, or ept violation)
This is the most complicated event. The cause of a page fault can be:
- a true guest fault (the guest translation won't allow the access) (*)
- access to a missing translation
- access to a protected translation
- when logging dirty pages, memory is write protected
- synchronized shadow pages are write protected (*)
- access to untranslatable memory (mmio)
(*) not applicable in direct mode
Handling a page fault is performed as follows:
- if needed, walk the guest page tables to determine the guest translation
(gva->gpa or ngpa->gpa)
- if permissions are insufficient, reflect the fault back to the guest
- determine the host page
- if this is an mmio request, there is no host page; call the emulator
to emulate the instruction instead
- walk the shadow page table to find the spte for the translation,
instantiating missing intermediate page tables as necessary
- try to unsynchronize the page
- if successful, we can let the guest continue and modify the gpte
- emulate the instruction
- if failed, unshadow the page and let the guest continue
- update any translations that were modified by the instruction
invlpg handling:
- walk the shadow page hierarchy and drop affected translations
- try to reinstantiate the indicated translation in the hope that the
guest will use it in the near future
Guest control register updates:
- mov to cr3
- look up new shadow roots
- synchronize newly reachable shadow pages
- mov to cr0/cr4/efer
- set up mmu context for new paging mode
- look up new shadow roots
- synchronize newly reachable shadow pages
Host translation updates:
- mmu notifier called with updated hva
- look up affected sptes through reverse map
- drop (or update) translations

should suspend or hibernate the laptop (and in the case of battery
alarms, unplug the AC adapter) to let it cool down. These alarms do
signal that something is wrong, they should never happen on normal
operating conditions.
The "extremely hot" alarms are emergencies. According to Lenovo, the
operating system is to force either an immediate suspend or hibernate
cycle, or a system shutdown. Obviously, something is very wrong if this
happens.

3.5 Overriding Configuration for Special Cases
----------------------------------------------
When using the bonding driver, the physical port which transmits a frame is
typically selected by the bonding driver, and is not relevant to the user or
system administrator. The output port is simply selected using the policies of
the selected bonding mode. On occasion however, it is helpful to direct certain
classes of traffic to certain physical interfaces on output to implement
slightly more complex policies. For example, to reach a web server over a
bonded interface in which eth0 connects to a private network, while eth1
connects via a public network, it may be desirous to bias the bond to send said
traffic over eth0 first, using eth1 only as a fall back, while all other traffic
can safely be sent over either interface. Such configurations may be achieved
using the traffic control utilities inherent in linux.
4. Querying Bonding Configuration By default the bonding driver is multiqueue aware and 16 queues are created
when the driver initializes (see Documentation/networking/multiqueue.txt
for details). If more or less queues are desired the module parameter
tx_queues can be used to change this value. There is no sysfs parameter
available as the allocation is done at module init time.
The output of the file /proc/net/bonding/bondX has changed so the output Queue
ID is now printed for each slave:
Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: eth0
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth0
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:1a:a0:12:8f:cb
Slave queue ID: 0
Slave Interface: eth1
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:1a:a0:12:8f:cc
Slave queue ID: 2
The queue_id for a slave can be set using the command:
# echo "eth1:2" > /sys/class/net/bond0/bonding/queue_id
Any interface that needs a queue_id set should set it with multiple calls
like the one above until proper priorities are set for all interfaces. On
distributions that allow configuration via initscripts, multiple 'queue_id'
arguments can be added to BONDING_OPTS to set all needed slave queues.
These queue id's can be used in conjunction with the tc utility to configure
a multiqueue qdisc and filters to bias certain traffic to transmit on certain
slave devices. For instance, say we wanted, in the above configuration to
force all traffic bound to 192.168.1.100 to use eth1 in the bond as its output
device. The following commands would accomplish this:
# tc qdisc add dev bond0 handle 1 root multiq
# tc filter add dev bond0 protocol ip parent 1: prio 1 u32 match ip dst \
192.168.1.100 action skbedit queue_mapping 2
These commands tell the kernel to attach a multiqueue queue discipline to the
bond0 interface and filter traffic enqueued to it, such that packets with a dst
ip of 192.168.1.100 have their output queue mapping value overwritten to 2.
This value is then passed into the driver, causing the normal output path
selection policy to be overridden, selecting instead qid 2, which maps to eth1.
Note that qid values begin at 1. Qid 0 is reserved to initiate to the driver
that normal output policy selection should take place. One benefit to simply
leaving the qid for a slave to 0 is the multiqueue awareness in the bonding
driver that is now present. This awareness allows tc filters to be placed on
slave devices as well as bond devices and the bonding driver will simply act as
a pass-through for selecting output queues on the slave device rather than
output port selection.
This feature first appeared in bonding driver version 3.7.0 and support for
output slave selection was limited to round-robin and active-backup modes.

- CAIF SPI porting -
- CAIF SPI basics:
Running CAIF over SPI needs some extra setup, owing to the nature of SPI.
Two extra GPIOs have been added in order to negotiate the transfers
between the master and the slave. The minimum requirement for running
CAIF over SPI is a SPI slave chip and two GPIOs (more details below).
Please note that running as a slave implies that you need to keep up
with the master clock. An overrun or underrun event is fatal.
- CAIF SPI framework:
To make porting as easy as possible, the CAIF SPI has been divided in
two parts. The first part (called the interface part) deals with all
generic functionality such as length framing, SPI frame negotiation
and SPI frame delivery and transmission. The other part is the CAIF
SPI slave device part, which is the module that you have to write if
you want to run SPI CAIF on a new hardware. This part takes care of
the physical hardware, both with regard to SPI and to GPIOs.
- Implementing a CAIF SPI device:
- Functionality provided by the CAIF SPI slave device:
In order to implement a SPI device you will, as a minimum,
need to implement the following
functions:
int (*init_xfer) (struct cfspi_xfer * xfer, struct cfspi_dev *dev):
This function is called by the CAIF SPI interface to give
you a chance to set up your hardware to be ready to receive
a stream of data from the master. The xfer structure contains
both physical and logical adresses, as well as the total length
of the transfer in both directions.The dev parameter can be used
to map to different CAIF SPI slave devices.
void (*sig_xfer) (bool xfer, struct cfspi_dev *dev):
This function is called by the CAIF SPI interface when the output
(SPI_INT) GPIO needs to change state. The boolean value of the xfer
variable indicates whether the GPIO should be asserted (HIGH) or
deasserted (LOW). The dev parameter can be used to map to different CAIF
SPI slave devices.
- Functionality provided by the CAIF SPI interface:
void (*ss_cb) (bool assert, struct cfspi_ifc *ifc);
This function is called by the CAIF SPI slave device in order to
signal a change of state of the input GPIO (SS) to the interface.
Only active edges are mandatory to be reported.
This function can be called from IRQ context (recommended in order
not to introduce latency). The ifc parameter should be the pointer
returned from the platform probe function in the SPI device structure.
void (*xfer_done_cb) (struct cfspi_ifc *ifc);
This function is called by the CAIF SPI slave device in order to
report that a transfer is completed. This function should only be
called once both the transmission and the reception are completed.
This function can be called from IRQ context (recommended in order
not to introduce latency). The ifc parameter should be the pointer
returned from the platform probe function in the SPI device structure.
- Connecting the bits and pieces:
- Filling in the SPI slave device structure:
Connect the necessary callback functions.
Indicate clock speed (used to calculate toggle delays).
Chose a suitable name (helps debugging if you use several CAIF
SPI slave devices).
Assign your private data (can be used to map to your structure).
- Filling in the SPI slave platform device structure:
Add name of driver to connect to ("cfspi_sspi").
Assign the SPI slave device structure as platform data.
- Padding:
In order to optimize throughput, a number of SPI padding options are provided.
Padding can be enabled independently for uplink and downlink transfers.
Padding can be enabled for the head, the tail and for the total frame size.
The padding needs to be correctly configured on both sides of the link.
The padding can be changed via module parameters in cfspi_sspi.c or via
the sysfs directory of the cfspi_sspi driver (before device registration).

Cirrus EP93xx SPI controller driver HOWTO
=========================================
ep93xx_spi driver brings SPI master support for EP93xx SPI controller. Chip
selects are implemented with GPIO lines.
NOTE: If possible, don't use SFRMOUT (SFRM1) signal as a chip select. It will
not work correctly (it cannot be controlled by software). Use GPIO lines
instead.
Sample configuration
====================
Typically driver configuration is done in platform board files (the files under
arch/arm/mach-ep93xx/*.c). In this example we configure MMC over SPI through
this driver on TS-7260 board. You can adapt the code to suit your needs.
This example uses EGPIO9 as SD/MMC card chip select (this is wired in DIO1
header on the board).
You need to select CONFIG_MMC_SPI to use mmc_spi driver.

The intent of this file is to have an uptodate, running commentary What is NUMA?
from different people about NUMA specific code in the Linux vm.
What is NUMA? It is an architecture where the memory access times This question can be answered from a couple of perspectives: the
for different regions of memory from a given processor varies hardware view and the Linux software view.
according to the "distance" of the memory region from the processor.
Each region of memory to which access times are the same from any
cpu, is called a node. On such architectures, it is beneficial if
the kernel tries to minimize inter node communications. Schemes
for this range from kernel text and read-only data replication
across nodes, and trying to house all the data structures that
key components of the kernel need on memory on that node.
Currently, all the numa support is to provide efficient handling From the hardware perspective, a NUMA system is a computer platform that
of widely discontiguous physical memory, so architectures which comprises multiple components or assemblies each of which may contain 0
are not NUMA but can have huge holes in the physical address space or more CPUs, local memory, and/or IO buses. For brevity and to
can use the same code. All this code is bracketed by CONFIG_DISCONTIGMEM. disambiguate the hardware view of these physical components/assemblies
from the software abstraction thereof, we'll call the components/assemblies
'cells' in this document.
The initial port includes NUMAizing the bootmem allocator code by Each of the 'cells' may be viewed as an SMP [symmetric multi-processor] subset
encapsulating all the pieces of information into a bootmem_data_t of the system--although some components necessary for a stand-alone SMP system
structure. Node specific calls have been added to the allocator. may not be populated on any given cell. The cells of the NUMA system are
In theory, any platform which uses the bootmem allocator should connected together with some sort of system interconnect--e.g., a crossbar or
be able to put the bootmem and mem_map data structures anywhere point-to-point link are common types of NUMA system interconnects. Both of
it deems best. these types of interconnects can be aggregated to create NUMA platforms with
cells at multiple distances from other cells.
Each node's page allocation data structures have also been encapsulated For Linux, the NUMA platforms of interest are primarily what is known as Cache
into a pg_data_t. The bootmem_data_t is just one part of this. To Coherent NUMA or ccNUMA systems. With ccNUMA systems, all memory is visible
make the code look uniform between NUMA and regular UMA platforms, to and accessible from any CPU attached to any cell and cache coherency
UMA platforms have a statically allocated pg_data_t too (contig_page_data). is handled in hardware by the processor caches and/or the system interconnect.
For the sake of uniformity, the function num_online_nodes() is also defined
for all platforms. As we run benchmarks, we might decide to NUMAize
more variables like low_on_memory, nr_free_pages etc into the pg_data_t.
The NUMA aware page allocation code currently tries to allocate pages Memory access time and effective memory bandwidth varies depending on how far
from different nodes in a round robin manner. This will be changed to away the cell containing the CPU or IO bus making the memory access is from the
do concentratic circle search, starting from current node, once the cell containing the target memory. For example, access to memory by CPUs
NUMA port achieves more maturity. The call alloc_pages_node has been attached to the same cell will experience faster access times and higher
added, so that drivers can make the call and not worry about whether bandwidths than accesses to memory on other, remote cells. NUMA platforms
it is running on a NUMA or UMA platform. can have cells at multiple remote distances from any given cell.
Platform vendors don't build NUMA systems just to make software developers'
lives interesting. Rather, this architecture is a means to provide scalable
memory bandwidth. However, to achieve scalable memory bandwidth, system and
application software must arrange for a large majority of the memory references
[cache misses] to be to "local" memory--memory on the same cell, if any--or
to the closest cell with memory.
This leads to the Linux software view of a NUMA system:
Linux divides the system's hardware resources into multiple software
abstractions called "nodes". Linux maps the nodes onto the physical cells
of the hardware platform, abstracting away some of the details for some
architectures. As with physical cells, software nodes may contain 0 or more
CPUs, memory and/or IO buses. And, again, memory accesses to memory on
"closer" nodes--nodes that map to closer cells--will generally experience
faster access times and higher effective bandwidth than accesses to more
remote cells.
For some architectures, such as x86, Linux will "hide" any node representing a
physical cell that has no memory attached, and reassign any CPUs attached to
that cell to a node representing a cell that does have memory. Thus, on
these architectures, one cannot assume that all CPUs that Linux associates with
a given node will see the same local memory access times and bandwidth.
In addition, for some architectures, again x86 is an example, Linux supports
the emulation of additional nodes. For NUMA emulation, linux will carve up
the existing nodes--or the system memory for non-NUMA platforms--into multiple
nodes. Each emulated node will manage a fraction of the underlying cells'
physical memory. NUMA emluation is useful for testing NUMA kernel and
application features on non-NUMA platforms, and as a sort of memory resource
management mechanism when used together with cpusets.
[see Documentation/cgroups/cpusets.txt]
For each node with memory, Linux constructs an independent memory management
subsystem, complete with its own free page lists, in-use page lists, usage
statistics and locks to mediate access. In addition, Linux constructs for
each memory zone [one or more of DMA, DMA32, NORMAL, HIGH_MEMORY, MOVABLE],
an ordered "zonelist". A zonelist specifies the zones/nodes to visit when a
selected zone/node cannot satisfy the allocation request. This situation,
when a zone has no available memory to satisfy a request, is called
"overflow" or "fallback".
Because some nodes contain multiple zones containing different types of
memory, Linux must decide whether to order the zonelists such that allocations
fall back to the same zone type on a different node, or to a different zone
type on the same node. This is an important consideration because some zones,
such as DMA or DMA32, represent relatively scarce resources. Linux chooses
a default zonelist order based on the sizes of the various zone types relative
to the total memory of the node and the total memory of the system. The
default zonelist order may be overridden using the numa_zonelist_order kernel
boot parameter or sysctl. [see Documentation/kernel-parameters.txt and
Documentation/sysctl/vm.txt]
By default, Linux will attempt to satisfy memory allocation requests from the
node to which the CPU that executes the request is assigned. Specifically,
Linux will attempt to allocate from the first node in the appropriate zonelist
for the node where the request originates. This is called "local allocation."
If the "local" node cannot satisfy the request, the kernel will examine other
nodes' zones in the selected zonelist looking for the first zone in the list
that can satisfy the request.
Local allocation will tend to keep subsequent access to the allocated memory
"local" to the underlying physical resources and off the system interconnect--
as long as the task on whose behalf the kernel allocated some memory does not
later migrate away from that memory. The Linux scheduler is aware of the
NUMA topology of the platform--embodied in the "scheduling domains" data
structures [see Documentation/scheduler/sched-domains.txt]--and the scheduler
attempts to minimize task migration to distant scheduling domains. However,
the scheduler does not take a task's NUMA footprint into account directly.
Thus, under sufficient imbalance, tasks can migrate between nodes, remote
from their initial node and kernel data structures.
System administrators and application designers can restrict a task's migration
to improve NUMA locality using various CPU affinity command line interfaces,
such as taskset(1) and numactl(1), and program interfaces such as
sched_setaffinity(2). Further, one can modify the kernel's default local
allocation behavior using Linux NUMA memory policy.
[see Documentation/vm/numa_memory_policy.]
System administrators can restrict the CPUs and nodes' memories that a non-
privileged user can specify in the scheduling or NUMA commands and functions
using control groups and CPUsets. [see Documentation/cgroups/CPUsets.txt]
On architectures that do not hide memoryless nodes, Linux will include only
zones [nodes] with memory in the zonelists. This means that for a memoryless
node the "local memory node"--the node of the first zone in CPU's node's
zonelist--will not be the node itself. Rather, it will be the node that the
kernel selected as the nearest node with memory when it built the zonelists.
So, default, local allocations will succeed with the kernel supplying the
closest available memory. This is a consequence of the same mechanism that
allows such allocations to fallback to other nearby nodes when a node that
does contain memory overflows.
Some kernel allocations do not want or cannot tolerate this allocation fallback
behavior. Rather they want to be sure they get memory from the specified node
or get notified that the node has no free memory. This is usually the case when
a subsystem allocates per CPU memory resources, for example.
A typical model for making such an allocation is to obtain the node id of the
node to which the "current CPU" is attached using one of the kernel's
numa_node_id() or CPU_to_node() functions and then request memory from only
the node id returned. When such an allocation fails, the requesting subsystem
may revert to its own fallback path. The slab kernel memory allocator is an
example of this. Or, the subsystem may choose to disable or not to enable
itself on allocation failure. The kernel profiling subsystem is an example of
this.
If the architecture supports--does not hide--memoryless nodes, then CPUs
attached to memoryless nodes would always incur the fallback path overhead
or some subsystems would fail to initialize if they attempted to allocated
memory exclusively from a node without memory. To support such
architectures transparently, kernel subsystems can use the numa_mem_id()
or cpu_to_mem() function to locate the "local memory node" for the calling or
specified CPU. Again, this is the same node from which default, local page
allocations will be attempted.
