+Description:
+
+Provide a place in sysfs for storing the ATA topology of the system. This allows
+retrieving various information about ATA objects.
+
+Files under /sys/class/ata_port
+-------------------------------
+
+ For each port, a directory ataX is created where X is the ata_port_id of
+ the port. The device parent is the ata host device.
+
+idle_irq (read)
+
+ Number of IRQ received by the port while idle [some ata HBA only].
+
+nr_pmp_links (read)
+
+ If a SATA Port Multiplier (PM) is connected, number of link behind it.
+
+Files under /sys/class/ata_link
+-------------------------------
+
+ Behind each port, there is a ata_link. If there is a SATA PM in the
+ topology, 15 ata_link objects are created.
+
+ If a link is behind a port, the directory name is linkX, where X is
+ ata_port_id of the port.
+ If a link is behind a PM, its name is linkX.Y where X is ata_port_id
+ of the parent port and Y the PM port.
+
+hw_sata_spd_limit
+
+ Maximum speed supported by the connected SATA device.
+
+sata_spd_limit
+
+ Maximum speed imposed by libata.
+
+sata_spd
+
+ Current speed of the link [1.5, 3Gps,...].
+
+Files under /sys/class/ata_device
+---------------------------------
+
+ Behind each link, up to two ata device are created.
+ The name of the directory is devX[.Y].Z where:
+ - X is ata_port_id of the port where the device is connected,
+ - Y the port of the PM if any, and
+ - Z the device id: for PATA, there is usually 2 devices [0,1],
+ only 1 for SATA.
+
+class
+ Device class. Can be "ata" for disk, "atapi" for packet device,
+ "pmp" for PM, or "none" if no device was found behind the link.
+
+dma_mode
+
+ Transfer modes supported by the device when in DMA mode.
+ Mostly used by PATA device.
+
+pio_mode
+
+ Transfer modes supported by the device when in PIO mode.
+ Mostly used by PATA device.
+
+xfer_mode
+
+ Current transfer mode.
+
+id
+
+ Cached result of IDENTIFY command, as described in ATA8 7.16 and 7.17.
+ Only valid if the device is not a PM.
+
+gscr
+
+ Cached result of the dump of PM GSCR register.
+ Valid registers are:
+ 0: SATA_PMP_GSCR_PROD_ID,
+ 1: SATA_PMP_GSCR_REV,
+ 2: SATA_PMP_GSCR_PORT_INFO,
+ 32: SATA_PMP_GSCR_ERROR,
+ 33: SATA_PMP_GSCR_ERROR_EN,
+ 64: SATA_PMP_GSCR_FEAT,
+ 96: SATA_PMP_GSCR_FEAT_EN,
+ 130: SATA_PMP_GSCR_SII_GPIO
+ Only valid if the device is a PM.
+
+spdn_cnt
+
+ Number of time libata decided to lower the speed of link due to errors.
+
+ering
+
+ Formatted output of the error ring of the device.

+ becomes idle at run time; they want the device to remain

+ period is called the autosuspend delay. Negative values will
+ prevent the device from being suspended at run time (similar
+ to writing "on" to the power/control attribute). Values >=
+ 1000 will cause the autosuspend timer expiration to be rounded
+ up to the nearest second.
+
+ Not all drivers support this attribute. If it isn't supported,
+ attempts to read or write it will yield I/O errors.

+ If you do not get any matches (or they appear to be false

+Date: October 2010
+Contact: James Hogan <james@albanarts.com>
+Description:
+ The /sys/power/pm_trace_dev_match file contains the name of the
+ device associated with the last PM event point saved in the RTC
+ across reboots when pm_trace has been used. More precisely it
+ contains the list of current devices (including those
+ registered by loadable kernel modules since boot) which match
+ the device hash in the RTC at boot, with a newline after each
+ one.
+
+ The advantage of this file over the hash matches printed to the
+ kernel log (see /sys/power/pm_trace), is that it includes
+ devices created after boot by loadable kernel modules.
+
+ Due to the small hash size necessary to fit in the RTC, it is
+ possible that more than one device matches the hash, in which
+ case further investigation is required to determine which
+ device is causing the problem. Note that genuine RTC clock
+ values (such as when pm_trace has not been used), can still
+ match a device and output it's name here.

+This document provides an overview of the msm_gpiomux interface, which
+is used to provide gpio pin multiplexing and configuration on mach-msm
+targets.
+
+History
+=======
+
+The first-generation API for gpio configuration & multiplexing on msm
+is the function gpio_tlmm_config(). This function has a few notable
+shortcomings, which led to its deprecation and replacement by gpiomux:
+
+The 'disable' parameter: Setting the second parameter to
+gpio_tlmm_config to GPIO_CFG_DISABLE tells the peripheral
+processor in charge of the subsystem to perform a look-up into a
+low-power table and apply the low-power/sleep setting for the pin.
+As the msm family evolved this became problematic. Not all pins
+have sleep settings, not all peripheral processors will accept requests
+to apply said sleep settings, and not all msm targets have their gpio
+subsystems managed by a peripheral processor. In order to get consistent
+behavior on all targets, drivers are forced to ignore this parameter,
+rendering it useless.
+
+The 'direction' flag: for all mux-settings other than raw-gpio (0),
+the output-enable bit of a gpio is hard-wired to a known
+input (usually VDD or ground). For those settings, the direction flag
+is meaningless at best, and deceptive at worst. In addition, using the
+direction flag to change output-enable (OE) directly can cause trouble in
+gpiolib, which has no visibility into gpio direction changes made
+in this way. Direction control in gpio mode should be made through gpiolib.
+
+Key Features of gpiomux
+=======================
+
+- A consistent interface across all generations of msm. Drivers can expect
+the same results on every target.
+- gpiomux plays nicely with gpiolib. Functions that should belong to gpiolib
+are left to gpiolib and not duplicated here. gpiomux is written with the
+intent that gpio_chips will call gpiomux reference-counting methods
+from their request() and free() hooks, providing full integration.
+- Tabular configuration. Instead of having to call gpio_tlmm_config
+hundreds of times, gpio configuration is placed in a single table.
+- Per-gpio sleep. Each gpio is individually reference counted, allowing only
+those lines which are in use to be put in high-power states.
+- 0 means 'do nothing': all flags are designed so that the default memset-zero
+equates to a sensible default of 'no configuration', preventing users
+from having to provide hundreds of 'no-op' configs for unused or
+unwanted lines.
+
+Usage
+=====
+
+To use gpiomux, provide configuration information for relevant gpio lines
+in the msm_gpiomux_configs table. Since a 0 equates to "unconfigured",
+only those lines to be managed by gpiomux need to be specified. Here
+is a completely fictional example:
+
+struct msm_gpiomux_config msm_gpiomux_configs[GPIOMUX_NGPIOS] = {
+ [12] = {
+ .active = GPIOMUX_VALID | GPIOMUX_DRV_8MA | GPIOMUX_FUNC_1,
+ .suspended = GPIOMUX_VALID | GPIOMUX_PULL_DOWN,
+ },
+ [34] = {
+ .suspended = GPIOMUX_VALID | GPIOMUX_PULL_DOWN,
+ },
+};
+
+To indicate that a gpio is in use, call msm_gpiomux_get() to increase
+its reference count. To decrease the reference count, call msm_gpiomux_put().
+
+The effect of this configuration is as follows:
+
+When the system boots, gpios 12 and 34 will be initialized with their
+'suspended' configurations. All other gpios, which were left unconfigured,
+will not be touched.
+
+When msm_gpiomux_get() is called on gpio 12 to raise its reference count
+above 0, its active configuration will be applied. Since no other gpio
+line has a valid active configuration, msm_gpiomux_get() will have no
+effect on any other line.
+
+When msm_gpiomux_put() is called on gpio 12 or 34 to drop their reference
+count to 0, their suspended configurations will be applied.
+Since no other gpio line has a valid suspended configuration, no other
+gpio line will be effected by msm_gpiomux_put(). Since gpio 34 has no valid
+active configuration, this is effectively a no-op for gpio 34 as well,
+with one small caveat, see the section "About Output-Enable Settings".
+
+All of the GPIOMUX_VALID flags may seem like unnecessary overhead, but
+they address some important issues. As unused entries (all those
+except 12 and 34) are zero-filled, gpiomux needs a way to distinguish
+the used fields from the unused. In addition, the all-zero pattern
+is a valid configuration! Therefore, gpiomux defines an additional bit
+which is used to indicate when a field is used. This has the pleasant
+side-effect of allowing calls to msm_gpiomux_write to use '0' to indicate
+that a value should not be changed:
+
+ msm_gpiomux_write(0, GPIOMUX_VALID, 0);
+
+replaces the active configuration of gpio 0 with an all-zero configuration,
+but leaves the suspended configuration as it was.
+
+Static Configurations
+=====================
+
+To install a static configuration, which is applied at boot and does
+not change after that, install a configuration with a suspended component
+but no active component, as in the previous example:
+
+ [34] = {
+ .suspended = GPIOMUX_VALID | GPIOMUX_PULL_DOWN,
+ },
+
+The suspended setting is applied during boot, and the lack of any valid
+active setting prevents any other setting from being applied at runtime.
+If other subsystems attempting to access the line is a concern, one could
+*really* anchor the configuration down by calling msm_gpiomux_get on the
+line at initialization to move the line into active mode. With the line
+held, it will never be re-suspended, and with no valid active configuration,
+no new configurations will be applied.
+
+But then, if having other subsystems grabbing for the line is truly a concern,
+it should be reserved with gpio_request instead, which carries an implicit
+msm_gpiomux_get.
+
+gpiomux and gpiolib
+===================
+
+It is expected that msm gpio_chips will call msm_gpiomux_get() and
+msm_gpiomux_put() from their request and free hooks, like this fictional
+example:
+
+static int request(struct gpio_chip *chip, unsigned offset)
+{
+ return msm_gpiomux_get(chip->base + offset);
+}
+
+static void free(struct gpio_chip *chip, unsigned offset)
+{
+ msm_gpiomux_put(chip->base + offset);
+}
+
+ ...somewhere in a gpio_chip declaration...
+ .request = request,
+ .free = free,
+
+This provides important functionality:
+- It guarantees that a gpio line will have its 'active' config applied
+ when the line is requested, and will not be suspended while the line
+ remains requested; and
+- It guarantees that gpio-direction settings from gpiolib behave sensibly.
+ See "About Output-Enable Settings."
+
+This mechanism allows for "auto-request" of gpiomux lines via gpiolib
+when it is suitable. Drivers wishing more exact control are, of course,
+free to also use msm_gpiomux_set and msm_gpiomux_get.
+
+About Output-Enable Settings
+============================
+
+Some msm targets do not have the ability to query the current gpio
+configuration setting. This means that changes made to the output-enable
+(OE) bit by gpiolib cannot be consistently detected and preserved by gpiomux.
+Therefore, when gpiomux applies a configuration setting, any direction
+settings which may have been applied by gpiolib are lost and the default
+input settings are re-applied.
+
+For this reason, drivers should not assume that gpio direction settings
+continue to hold if they free and then re-request a gpio. This seems like
+common sense - after all, anybody could have obtained the line in the
+meantime - but it needs saying.
+
+This also means that calls to msm_gpiomux_write will reset the OE bit,
+which means that if the gpio line is held by a client of gpiolib and
+msm_gpiomux_write is called, the direction setting has been lost and
+gpiolib's internal state has been broken.
+Release gpio lines before reconfiguring them.

-I/O Barriers
-============
-Tejun Heo <htejun@gmail.com>, July 22 2005
-
-I/O barrier requests are used to guarantee ordering around the barrier
-requests. Unless you're crazy enough to use disk drives for
-implementing synchronization constructs (wow, sounds interesting...),
-the ordering is meaningful only for write requests for things like
-journal checkpoints. All requests queued before a barrier request
-must be finished (made it to the physical medium) before the barrier
-request is started, and all requests queued after the barrier request
-must be started only after the barrier request is finished (again,
-made it to the physical medium).
-
-In other words, I/O barrier requests have the following two properties.
-
-1. Request ordering
-
-Requests cannot pass the barrier request. Preceding requests are
-processed before the barrier and following requests after.
-
-Depending on what features a drive supports, this can be done in one
-of the following three ways.
-
-i. For devices which have queue depth greater than 1 (TCQ devices) and
-support ordered tags, block layer can just issue the barrier as an
-ordered request and the lower level driver, controller and drive
-itself are responsible for making sure that the ordering constraint is
-met. Most modern SCSI controllers/drives should support this.
-
-NOTE: SCSI ordered tag isn't currently used due to limitation in the
- SCSI midlayer, see the following random notes section.
-
-ii. For devices which have queue depth greater than 1 but don't
-support ordered tags, block layer ensures that the requests preceding
-a barrier request finishes before issuing the barrier request. Also,
-it defers requests following the barrier until the barrier request is
-finished. Older SCSI controllers/drives and SATA drives fall in this
-category.
-
-iii. Devices which have queue depth of 1. This is a degenerate case
-of ii. Just keeping issue order suffices. Ancient SCSI
-controllers/drives and IDE drives are in this category.
-
-2. Forced flushing to physical medium
-
-Again, if you're not gonna do synchronization with disk drives (dang,
-it sounds even more appealing now!), the reason you use I/O barriers
-is mainly to protect filesystem integrity when power failure or some
-other events abruptly stop the drive from operating and possibly make
-the drive lose data in its cache. So, I/O barriers need to guarantee
-that requests actually get written to non-volatile medium in order.
-
-There are four cases,
-
-i. No write-back cache. Keeping requests ordered is enough.
-
-ii. Write-back cache but no flush operation. There's no way to
-guarantee physical-medium commit order. This kind of devices can't to
-I/O barriers.
-
-iii. Write-back cache and flush operation but no FUA (forced unit
-access). We need two cache flushes - before and after the barrier
-request.
-
-iv. Write-back cache, flush operation and FUA. We still need one
-flush to make sure requests preceding a barrier are written to medium,
-but post-barrier flush can be avoided by using FUA write on the
-barrier itself.
-
-
-How to support barrier requests in drivers
-------------------------------------------
-
-All barrier handling is done inside block layer proper. All low level
-drivers have to are implementing its prepare_flush_fn and using one
-the following two functions to indicate what barrier type it supports
-and how to prepare flush requests. Note that the term 'ordered' is
-used to indicate the whole sequence of performing barrier requests
-including draining and flushing.
-
-typedef void (prepare_flush_fn)(struct request_queue *q, struct request *rq);
-
-int blk_queue_ordered(struct request_queue *q, unsigned ordered,
- prepare_flush_fn *prepare_flush_fn);
-
-@q : the queue in question
-@ordered : the ordered mode the driver/device supports
-@prepare_flush_fn : this function should prepare @rq such that it
- flushes cache to physical medium when executed
-
-For example, SCSI disk driver's prepare_flush_fn looks like the
-following.
-
-static void sd_prepare_flush(struct request_queue *q, struct request *rq)
-{
- memset(rq->cmd, 0, sizeof(rq->cmd));
- rq->cmd_type = REQ_TYPE_BLOCK_PC;
- rq->timeout = SD_TIMEOUT;
- rq->cmd[0] = SYNCHRONIZE_CACHE;
- rq->cmd_len = 10;

-Random notes/caveats
---------------------
-
-* SCSI layer currently can't use TAG ordering even if the drive,
-controller and driver support it. The problem is that SCSI midlayer
-request dispatch function is not atomic. It releases queue lock and
-switch to SCSI host lock during issue and it's possible and likely to
-happen in time that requests change their relative positions. Once
-this problem is solved, TAG ordering can be enabled.
-
-* Currently, no matter which ordered mode is used, there can be only
-one barrier request in progress. All I/O barriers are held off by
-block layer until the previous I/O barrier is complete. This doesn't
-make any difference for DRAIN ordered devices, but, for TAG ordered
-devices with very high command latency, passing multiple I/O barriers
-to low level *might* be helpful if they are very frequent. Well, this
-certainly is a non-issue. I'm writing this just to make clear that no
-two I/O barrier is ever passed to low-level driver.
-
-* Completion order. Requests in ordered sequence are issued in order
-but not required to finish in order. Barrier implementation can
-handle out-of-order completion of ordered sequence. IOW, the requests
-MUST be processed in order but the hardware/software completion paths
-are allowed to reorder completion notifications - eg. current SCSI
-midlayer doesn't preserve completion order during error handling.
-
-* Requeueing order. Low-level drivers are free to requeue any request
-after they removed it from the request queue with
-blkdev_dequeue_request(). As barrier sequence should be kept in order
-when requeued, generic elevator code takes care of putting requests in
-order around barrier. See blk_ordered_req_seq() and
-ELEVATOR_INSERT_REQUEUE handling in __elv_add_request() for details.
-
-Note that block drivers must not requeue preceding requests while
-completing latter requests in an ordered sequence. Currently, no
-error checking is done against this.
-
-* Error handling. Currently, block layer will report error to upper
-layer if any of requests in an ordered sequence fails. Unfortunately,
-this doesn't seem to be enough. Look at the following request flow.
-QUEUE_ORDERED_TAG_FLUSH is in use.
-
- [0] [1] [2] [3] [pre] [barrier] [post] < [4] [5] [6] ... >
- still in elevator
-
-Let's say request [2], [3] are write requests to update file system
-metadata (journal or whatever) and [barrier] is used to mark that
-those updates are valid. Consider the following sequence.
-
- i. Requests [0] ~ [post] leaves the request queue and enters
- low-level driver.
- ii. After a while, unfortunately, something goes wrong and the
- drive fails [2]. Note that any of [0], [1] and [3] could have
- completed by this time, but [pre] couldn't have been finished
- as the drive must process it in order and it failed before
- processing that command.
- iii. Error handling kicks in and determines that the error is
- unrecoverable and fails [2], and resumes operation.
- iv. [pre] [barrier] [post] gets processed.
- v. *BOOM* power fails
-
-The problem here is that the barrier request is *supposed* to indicate
-that filesystem update requests [2] and [3] made it safely to the
-physical medium and, if the machine crashes after the barrier is
-written, filesystem recovery code can depend on that. Sadly, that
-isn't true in this case anymore. IOW, the success of a I/O barrier
-should also be dependent on success of some of the preceding requests,
-where only upper layer (filesystem) knows what 'some' is.
-
-This can be solved by implementing a way to tell the block layer which
-requests affect the success of the following barrier request and
-making lower lever drivers to resume operation on error only after
-block layer tells it to do so.
-
-As the probability of this happening is very low and the drive should
-be faulty, implementing the fix is probably an overkill. But, still,
-it's there.
-
-* In previous drafts of barrier implementation, there was fallback
-mechanism such that, if FUA or ordered TAG fails, less fancy ordered
-mode can be selected and the failed barrier request is retried
-automatically. The rationale for this feature was that as FUA is
-pretty new in ATA world and ordered tag was never used widely, there
-could be devices which report to support those features but choke when
-actually given such requests.
-
- This was removed for two reasons 1. it's an overkill 2. it's
-impossible to implement properly when TAG ordering is used as low
-level drivers resume after an error automatically. If it's ever
-needed adding it back and modifying low level drivers accordingly
-shouldn't be difficult.

+CFQ ioscheduler tunables
+========================
+
+slice_idle
+----------
+This specifies how long CFQ should idle for next request on certain cfq queues
+(for sequential workloads) and service trees (for random workloads) before
+queue is expired and CFQ selects next queue to dispatch from.
+
+By default slice_idle is a non-zero value. That means by default we idle on
+queues/service trees. This can be very helpful on highly seeky media like
+single spindle SATA/SAS disks where we can cut down on overall number of
+seeks and see improved throughput.
+
+Setting slice_idle to 0 will remove all the idling on queues/service tree
+level and one should see an overall improved throughput on faster storage
+devices like multiple SATA/SAS disks in hardware RAID configuration. The down
+side is that isolation provided from WRITES also goes down and notion of
+IO priority becomes weaker.
+
+So depending on storage and workload, it might be useful to set slice_idle=0.
+In general I think for SATA/SAS disks and software RAID of SATA/SAS disks
+keeping slice_idle enabled should be useful. For any configurations where
+there are multiple spindles behind single LUN (Host based hardware RAID
+controller or for storage arrays), setting slice_idle=0 might end up in better
+throughput and acceptable latencies.
+
+CFQ IOPS Mode for group scheduling
+===================================
+Basic CFQ design is to provide priority based time slices. Higher priority
+process gets bigger time slice and lower priority process gets smaller time
+slice. Measuring time becomes harder if storage is fast and supports NCQ and
+it would be better to dispatch multiple requests from multiple cfq queues in
+request queue at a time. In such scenario, it is not possible to measure time
+consumed by single queue accurately.
+
+What is possible though is to measure number of requests dispatched from a
+single queue and also allow dispatch from multiple cfq queue at the same time.
+This effectively becomes the fairness in terms of IOPS (IO operations per
+second).
+
+If one sets slice_idle=0 and if storage supports NCQ, CFQ internally switches
+to IOPS mode and starts providing fairness in terms of number of requests
+dispatched. Note that this mode switching takes effect only for group
+scheduling. For non-cgroup users nothing should change.

+
+Explicit volatile write back cache control
+=====================================
+
+Introduction
+------------
+
+Many storage devices, especially in the consumer market, come with volatile
+write back caches. That means the devices signal I/O completion to the
+operating system before data actually has hit the non-volatile storage. This
+behavior obviously speeds up various workloads, but it means the operating
+system needs to force data out to the non-volatile storage when it performs
+a data integrity operation like fsync, sync or an unmount.
+
+The Linux block layer provides two simple mechanisms that let filesystems
+control the caching behavior of the storage device. These mechanisms are
+a forced cache flush, and the Force Unit Access (FUA) flag for requests.
+
+
+Explicit cache flushes
+----------------------
+
+The REQ_FLUSH flag can be OR ed into the r/w flags of a bio submitted from
+the filesystem and will make sure the volatile cache of the storage device
+has been flushed before the actual I/O operation is started. This explicitly
+guarantees that previously completed write requests are on non-volatile
+storage before the flagged bio starts. In addition the REQ_FLUSH flag can be
+set on an otherwise empty bio structure, which causes only an explicit cache
+flush without any dependent I/O. It is recommend to use
+the blkdev_issue_flush() helper for a pure cache flush.
+
+
+Forced Unit Access
+-----------------
+
+The REQ_FUA flag can be OR ed into the r/w flags of a bio submitted from the
+filesystem and will make sure that I/O completion for this request is only
+signaled after the data has been committed to non-volatile storage.
+
+
+Implementation details for filesystems
+--------------------------------------
+
+Filesystems can simply set the REQ_FLUSH and REQ_FUA bits and do not have to
+worry if the underlying devices need any explicit cache flushing and how
+the Forced Unit Access is implemented. The REQ_FLUSH and REQ_FUA flags
+may both be set on a single bio.
+
+
+Implementation details for make_request_fn based block drivers
+--------------------------------------------------------------
+
+These drivers will always see the REQ_FLUSH and REQ_FUA bits as they sit
+directly below the submit_bio interface. For remapping drivers the REQ_FUA
+bits need to be propagated to underlying devices, and a global flush needs
+to be implemented for bios with the REQ_FLUSH bit set. For real device
+drivers that do not have a volatile cache the REQ_FLUSH and REQ_FUA bits
+on non-empty bios can simply be ignored, and REQ_FLUSH requests without
+data can be completed successfully without doing any work. Drivers for
+devices with volatile caches need to implement the support for these
+flags themselves without any help from the block layer.
+
+
+Implementation details for request_fn based block drivers
+--------------------------------------------------------------
+
+For devices that do not support volatile write caches there is no driver
+support required, the block layer completes empty REQ_FLUSH requests before
+entering the driver and strips off the REQ_FLUSH and REQ_FUA bits from
+requests that have a payload. For devices with volatile write caches the
+driver needs to tell the block layer that it supports flushing caches by
+doing:
+
+ blk_queue_flush(sdkp->disk->queue, REQ_FLUSH);
+
+and handle empty REQ_FLUSH requests in its prep_fn/request_fn. Note that
+REQ_FLUSH requests with a payload are automatically turned into a sequence
+of an empty REQ_FLUSH request followed by the actual write by the block
+layer. For devices that also support the FUA bit the block layer needs
+to be told to pass through the REQ_FUA bit using:
+
+ blk_queue_flush(sdkp->disk->queue, REQ_FLUSH | REQ_FUA);
+
+and the driver must handle write requests that have the REQ_FUA bit set
+in prep_fn/request_fn. If the FUA bit is not natively supported the block
+layer turns it into an empty REQ_FLUSH request after the actual write.

+On certain non-Intel architectures, it has been observed that intense TX

+have stalled for as much as 10 seconds before it resumes.
+
+The improper writeback does not occur on the first descriptor in a system
+memory cache-line, which is typically 32 bytes, or 4 descriptors long.

+Setting TxDescriptorStep to a value of 4 will ensure that all TX descriptors

Additional Configurations
=========================
- Configuring the Driver on Different Distributions
- -------------------------------------------------
- Configuring a network driver to load properly when the system is started
- is distribution dependent. Typically, the configuration process involves
- adding an alias line to /etc/modules.conf or /etc/modprobe.conf as well
- as editing other system startup scripts and/or configuration files. Many
- popular Linux distributions ship with tools to make these changes for you.
- To learn the proper way to configure a network device for your system,
- refer to your distribution documentation. If during this process you are
- asked for the driver or module name, the name for the Linux Base Driver
- for the Intel(R) PRO/1000 Family of Adapters is e1000.
-
- As an example, if you install the e1000 driver for two PRO/1000 adapters
- (eth0 and eth1) and set the speed and duplex to 10full and 100half, add
- the following to modules.conf or or modprobe.conf:
-
- alias eth0 e1000
- alias eth1 e1000
- options e1000 Speed=10,100 Duplex=2,1

- Viewing Link Messages
- ---------------------
- Link messages will not be displayed to the console if the distribution is

-Known Issues
-============
-
-Dropped Receive Packets on Half-duplex 10/100 Networks
-------------------------------------------------------
-If you have an Intel PCI Express adapter running at 10mbps or 100mbps, half-
-duplex, you may observe occasional dropped receive packets. There are no
-workarounds for this problem in this network configuration. The network must
-be updated to operate in full-duplex, and/or 1000mbps only.
-
-Jumbo Frames System Requirement
--------------------------------
-Memory allocation failures have been observed on Linux systems with 64 MB
-of RAM or less that are running Jumbo Frames. If you are using Jumbo
-Frames, your system may require more than the advertised minimum
-requirement of 64 MB of system memory.
-
-Performance Degradation with Jumbo Frames
------------------------------------------
-Degradation in throughput performance may be observed in some Jumbo frames
-environments. If this is observed, increasing the application's socket
-buffer size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values
-may help. See the specific application manual and
-/usr/src/linux*/Documentation/
-networking/ip-sysctl.txt for more details.
-
-Jumbo Frames on Foundry BigIron 8000 switch
--------------------------------------------
-There is a known issue using Jumbo frames when connected to a Foundry
-BigIron 8000 switch. This is a 3rd party limitation. If you experience
-loss of packets, lower the MTU size.
-
-Allocating Rx Buffers when Using Jumbo Frames
----------------------------------------------
-Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
-the available memory is heavily fragmented. This issue may be seen with PCI-X
-adapters or with packet split disabled. This can be reduced or eliminated
-by changing the amount of available memory for receive buffer allocation, by
-increasing /proc/sys/vm/min_free_kbytes.
-
-Multiple Interfaces on Same Ethernet Broadcast Network
-------------------------------------------------------
-Due to the default ARP behavior on Linux, it is not possible to have
-one system on two IP networks in the same Ethernet broadcast domain
-(non-partitioned switch) behave as expected. All Ethernet interfaces
-will respond to IP traffic for any IP address assigned to the system.
-This results in unbalanced receive traffic.
-
-If you have multiple interfaces in a server, either turn on ARP
-filtering by entering:
-
- echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
-(this only works if your kernel's version is higher than 2.4.5),
-
-NOTE: This setting is not saved across reboots. The configuration
-change can be made permanent by adding the line:
- net.ipv4.conf.all.arp_filter = 1
-to the file /etc/sysctl.conf
-
- or,
-
-install the interfaces in separate broadcast domains (either in
-different switches or in a switch partitioned to VLANs).
-
-82541/82547 can't link or are slow to link with some link partners
------------------------------------------------------------------
-There is a known compatibility issue with 82541/82547 and some
-low-end switches where the link will not be established, or will
-be slow to establish. In particular, these switches are known to
-be incompatible with 82541/82547:
-
- Planex FXG-08TE
- I-O Data ETG-SH8
-
-To workaround this issue, the driver can be compiled with an override
-of the PHY's master/slave setting. Forcing master or forcing slave
-mode will improve time-to-link.
-
- # make CFLAGS_EXTRA=-DE1000_MASTER_SLAVE=<n>
-
-Where <n> is:
-
- 0 = Hardware default
- 1 = Master mode
- 2 = Slave mode
- 3 = Auto master/slave
-
-Disable rx flow control with ethtool
-------------------------------------
-In order to disable receive flow control using ethtool, you must turn
-off auto-negotiation on the same command line.
-
-For example:
-
- ethtool -A eth? autoneg off rx off
-
-Unplugging network cable while ethtool -p is running
-----------------------------------------------------
-In kernel versions 2.5.50 and later (including 2.6 kernel), unplugging
-the network cable while ethtool -p is running will cause the system to
-become unresponsive to keyboard commands, except for control-alt-delete.
-Restarting the system appears to be the only remedy.

+Identifying Your Adapter
+========================
+
+The e1000e driver supports all PCI Express Intel(R) Gigabit Network
+Connections, except those that are 82575, 82576 and 82580-based*.
+
+* NOTE: The Intel(R) PRO/1000 P Dual Port Server Adapter is supported by
+ the e1000 driver, not the e1000e driver due to the 82546 part being used
+ behind a PCI Express bridge.
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+ http://support.intel.com/support/go/network/adapter/idguide.htm
+
+For the latest Intel network drivers for Linux, refer to the following
+website. In the search field, enter your adapter name or type, or use the

+
+Command Line Parameters
+=======================
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTES: For more information about the InterruptThrottleRate,
+ RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
+ parameters, see the application note at:
+ http://www.intel.com/design/network/applnots/ap450.htm
+
+InterruptThrottleRate
+---------------------
+Valid Range: 0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
+ 4=simplified balancing)
+Default Value: 3
+
+The driver can limit the amount of interrupts per second that the adapter
+will generate for incoming packets. It does this by writing a value to the
+adapter that is based on the maximum amount of interrupts that the adapter
+will generate per second.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes. Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
+for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
+latency" or "Lowest latency" class, the InterruptThrottleRate is increased
+stepwise to 20000. This default mode is suitable for most applications.
+
+For situations where low latency is vital such as cluster or
+grid computing, the algorithm can reduce latency even more when
+InterruptThrottleRate is set to mode 1. In this mode, which operates
+the same as mode 3, the InterruptThrottleRate will be increased stepwise to
+70000 for traffic in class "Lowest latency".
+
+In simplified mode the interrupt rate is based on the ratio of Tx and
+Rx traffic. If the bytes per second rate is approximately equal the
+interrupt rate will drop as low as 2000 interrupts per second. If the
+traffic is mostly transmit or mostly receive, the interrupt rate could
+be as high as 8000.
+
+Setting InterruptThrottleRate to 0 turns off any interrupt moderation
+and may improve small packet latency, but is generally not suitable
+for bulk throughput traffic.
+
+NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
+ RxAbsIntDelay parameters. In other words, minimizing the receive
+ and/or transmit absolute delays does not force the controller to
+ generate more interrupts than what the Interrupt Throttle Rate
+ allows.
+
+NOTE: When e1000e is loaded with default settings and multiple adapters
+ are in use simultaneously, the CPU utilization may increase non-
+ linearly. In order to limit the CPU utilization without impacting
+ the overall throughput, we recommend that you load the driver as
+ follows:
+
+ modprobe e1000e InterruptThrottleRate=3000,3000,3000
+
+ This sets the InterruptThrottleRate to 3000 interrupts/sec for
+ the first, second, and third instances of the driver. The range
+ of 2000 to 3000 interrupts per second works on a majority of
+ systems and is a good starting point, but the optimal value will
+ be platform-specific. If CPU utilization is not a concern, use
+ RX_POLLING (NAPI) and default driver settings.
+
+RxIntDelay
+----------
+Valid Range: 0-65535 (0=off)
+Default Value: 0
+
+This value delays the generation of receive interrupts in units of 1.024
+microseconds. Receive interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. Increasing this value adds
+extra latency to frame reception and can end up decreasing the throughput
+of TCP traffic. If the system is reporting dropped receives, this value
+may be set too high, causing the driver to run out of available receive
+descriptors.
+
+CAUTION: When setting RxIntDelay to a value other than 0, adapters may
+ hang (stop transmitting) under certain network conditions. If
+ this occurs a NETDEV WATCHDOG message is logged in the system
+ event log. In addition, the controller is automatically reset,
+ restoring the network connection. To eliminate the potential
+ for the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay
+-------------
+Valid Range: 0-65535 (0=off)
+Default Value: 8
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+receive interrupt is generated. Useful only if RxIntDelay is non-zero,
+this value ensures that an interrupt is generated after the initial
+packet is received within the set amount of time. Proper tuning,
+along with RxIntDelay, may improve traffic throughput in specific network
+conditions.
+
+TxIntDelay
+----------
+Valid Range: 0-65535 (0=off)
+Default Value: 8
+
+This value delays the generation of transmit interrupts in units of
+1.024 microseconds. Transmit interrupt reduction can improve CPU
+efficiency if properly tuned for specific network traffic. If the
+system is reporting dropped transmits, this value may be set too high
+causing the driver to run out of available transmit descriptors.
+
+TxAbsIntDelay
+-------------
+Valid Range: 0-65535 (0=off)
+Default Value: 32
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+transmit interrupt is generated. Useful only if TxIntDelay is non-zero,
+this value ensures that an interrupt is generated after the initial
+packet is sent on the wire within the set amount of time. Proper tuning,
+along with TxIntDelay, may improve traffic throughput in specific
+network conditions.
+
+Copybreak
+---------
+Valid Range: 0-xxxxxxx (0=off)
+Default Value: 256
+
+Driver copies all packets below or equaling this size to a fresh Rx
+buffer before handing it up the stack.
+
+This parameter is different than other parameters, in that it is a
+single (not 1,1,1 etc.) parameter applied to all driver instances and
+it is also available during runtime at
+/sys/module/e1000e/parameters/copybreak
+
+SmartPowerDownEnable
+--------------------
+Valid Range: 0-1
+Default Value: 0 (disabled)
+
+Allows PHY to turn off in lower power states. The user can set this parameter
+in supported chipsets.
+
+KumeranLockLoss
+---------------
+Valid Range: 0-1
+Default Value: 1 (enabled)
+
+This workaround skips resetting the PHY at shutdown for the initial
+silicon releases of ICH8 systems.
+
+IntMode
+-------
+Valid Range: 0-2 (0=legacy, 1=MSI, 2=MSI-X)
+Default Value: 2
+
+Allows changing the interrupt mode at module load time, without requiring a
+recompile. If the driver load fails to enable a specific interrupt mode, the
+driver will try other interrupt modes, from least to most compatible. The
+interrupt order is MSI-X, MSI, Legacy. If specifying MSI (IntMode=1)
+interrupts, only MSI and Legacy will be attempted.
+
+CrcStripping
+------------
+Valid Range: 0-1
+Default Value: 1 (enabled)
+
+Strip the CRC from received packets before sending up the network stack. If
+you have a machine with a BMC enabled but cannot receive IPMI traffic after
+loading or enabling the driver, try disabling this feature.
+
+WriteProtectNVM
+---------------
+Valid Range: 0-1
+Default Value: 1 (enabled)
+
+Set the hardware to ignore all write/erase cycles to the GbE region in the
+ICHx NVM (non-volatile memory). This feature can be disabled by the
+WriteProtectNVM module parameter (enabled by default) only after a hardware
+reset, but the machine must be power cycled before trying to enable writes.
+
+Note: the kernel boot option iomem=relaxed may need to be set if the kernel
+config option CONFIG_STRICT_DEVMEM=y, if the root user wants to write the
+NVM from user space via ethtool.
+
+Additional Configurations
+=========================
+
+ Jumbo Frames
+ ------------
+ Jumbo Frames support is enabled by changing the MTU to a value larger than
+ the default of 1500. Use the ifconfig command to increase the MTU size.
+ For example:
+
+ ifconfig eth<x> mtu 9000 up
+
+ This setting is not saved across reboots.
+
+ Notes:
+
+ - The maximum MTU setting for Jumbo Frames is 9216. This value coincides
+ with the maximum Jumbo Frames size of 9234 bytes.
+
+ - Using Jumbo Frames at 10 or 100 Mbps is not supported and may result in
+ poor performance or loss of link.
+
+ - Some adapters limit Jumbo Frames sized packets to a maximum of
+ 4096 bytes and some adapters do not support Jumbo Frames.
+
+
+ Ethtool
+ -------
+ The driver utilizes the ethtool interface for driver configuration and
+ diagnostics, as well as displaying statistical information. We
+ strongly recommend downloading the latest version of Ethtool at:
+
+ http://sourceforge.net/projects/gkernel.
+
+ Speed and Duplex
+ ----------------
+ Speed and Duplex are configured through the Ethtool* utility. For
+ instructions, refer to the Ethtool man page.
+
+ Enabling Wake on LAN* (WoL)
+ ---------------------------
+ WoL is configured through the Ethtool* utility. For instructions on
+ enabling WoL with Ethtool, refer to the Ethtool man page.
+
+ WoL will be enabled on the system during the next shut down or reboot.
+ For this driver version, in order to enable WoL, the e1000e driver must be
+ loaded when shutting down or rebooting the system.
+
+ In most cases Wake On LAN is only supported on port A for multiple port
+ adapters. To verify if a port supports Wake on LAN run ethtool eth<X>.

+
+1. Introduction
+===============
+Complex SoCs of today consists of a multiple sub-modules working in conjunction.
+In an operational system executing varied use cases, not all modules in the SoC
+need to function at their highest performing frequency all the time. To
+facilitate this, sub-modules in a SoC are grouped into domains, allowing some
+domains to run at lower voltage and frequency while other domains are loaded
+more. The set of discrete tuples consisting of frequency and voltage pairs that
+the device will support per domain are called Operating Performance Points or
+OPPs.
+
+OPP library provides a set of helper functions to organize and query the OPP
+information. The library is located in drivers/base/power/opp.c and the header
+is located in include/linux/opp.h. OPP library can be enabled by enabling
+CONFIG_PM_OPP from power management menuconfig menu. OPP library depends on
+CONFIG_PM as certain SoCs such as Texas Instrument's OMAP framework allows to
+optionally boot at a certain OPP without needing cpufreq.
+
+Typical usage of the OPP library is as follows:
+(users) -> registers a set of default OPPs -> (library)
+SoC framework -> modifies on required cases certain OPPs -> OPP layer
+ -> queries to search/retrieve information ->
+
+OPP layer expects each domain to be represented by a unique device pointer. SoC
+framework registers a set of initial OPPs per device with the OPP layer. This
+list is expected to be an optimally small number typically around 5 per device.
+This initial list contains a set of OPPs that the framework expects to be safely
+enabled by default in the system.
+
+Note on OPP Availability:
+------------------------
+As the system proceeds to operate, SoC framework may choose to make certain
+OPPs available or not available on each device based on various external
+factors. Example usage: Thermal management or other exceptional situations where
+SoC framework might choose to disable a higher frequency OPP to safely continue
+operations until that OPP could be re-enabled if possible.
+
+OPP library facilitates this concept in it's implementation. The following
+operational functions operate only on available opps:
+opp_find_freq_{ceil, floor}, opp_get_voltage, opp_get_freq, opp_get_opp_count
+and opp_init_cpufreq_table
+
+opp_find_freq_exact is meant to be used to find the opp pointer which can then
+be used for opp_enable/disable functions to make an opp available as required.
+
+WARNING: Users of OPP library should refresh their availability count using
+get_opp_count if opp_enable/disable functions are invoked for a device, the
+exact mechanism to trigger these or the notification mechanism to other
+dependent subsystems such as cpufreq are left to the discretion of the SoC
+specific framework which uses the OPP library. Similar care needs to be taken
+care to refresh the cpufreq table in cases of these operations.
+
+WARNING on OPP List locking mechanism:
+-------------------------------------------------
+OPP library uses RCU for exclusivity. RCU allows the query functions to operate
+in multiple contexts and this synchronization mechanism is optimal for a read
+intensive operations on data structure as the OPP library caters to.
+
+To ensure that the data retrieved are sane, the users such as SoC framework
+should ensure that the section of code operating on OPP queries are locked
+using RCU read locks. The opp_find_freq_{exact,ceil,floor},
+opp_get_{voltage, freq, opp_count} fall into this category.
+
+opp_{add,enable,disable} are updaters which use mutex and implement it's own
+RCU locking mechanisms. opp_init_cpufreq_table acts as an updater and uses
+mutex to implment RCU updater strategy. These functions should *NOT* be called
+under RCU locks and other contexts that prevent blocking functions in RCU or
+mutex operations from working.
+
+2. Initial OPP List Registration
+================================
+The SoC implementation calls opp_add function iteratively to add OPPs per
+device. It is expected that the SoC framework will register the OPP entries
+optimally- typical numbers range to be less than 5. The list generated by
+registering the OPPs is maintained by OPP library throughout the device
+operation. The SoC framework can subsequently control the availability of the
+OPPs dynamically using the opp_enable / disable functions.
+
+opp_add - Add a new OPP for a specific domain represented by the device pointer.
+ The OPP is defined using the frequency and voltage. Once added, the OPP
+ is assumed to be available and control of it's availability can be done
+ with the opp_enable/disable functions. OPP library internally stores
+ and manages this information in the opp struct. This function may be
+ used by SoC framework to define a optimal list as per the demands of
+ SoC usage environment.
+
+ WARNING: Do not use this function in interrupt context.
+
+ Example:
+ soc_pm_init()
+ {
+ /* Do things */
+ r = opp_add(mpu_dev, 1000000, 900000);
+ if (!r) {
+ pr_err("%s: unable to register mpu opp(%d)\n", r);
+ goto no_cpufreq;
+ }
+ /* Do cpufreq things */
+ no_cpufreq:
+ /* Do remaining things */
+ }
+
+3. OPP Search Functions
+=======================
+High level framework such as cpufreq operates on frequencies. To map the
+frequency back to the corresponding OPP, OPP library provides handy functions
+to search the OPP list that OPP library internally manages. These search
+functions return the matching pointer representing the opp if a match is
+found, else returns error. These errors are expected to be handled by standard
+error checks such as IS_ERR() and appropriate actions taken by the caller.
+
+opp_find_freq_exact - Search for an OPP based on an *exact* frequency and
+ availability. This function is especially useful to enable an OPP which
+ is not available by default.
+ Example: In a case when SoC framework detects a situation where a
+ higher frequency could be made available, it can use this function to
+ find the OPP prior to call the opp_enable to actually make it available.
+ rcu_read_lock();
+ opp = opp_find_freq_exact(dev, 1000000000, false);
+ rcu_read_unlock();
+ /* dont operate on the pointer.. just do a sanity check.. */
+ if (IS_ERR(opp)) {
+ pr_err("frequency not disabled!\n");
+ /* trigger appropriate actions.. */
+ } else {
+ opp_enable(dev,1000000000);
+ }
+
+ NOTE: This is the only search function that operates on OPPs which are
+ not available.
+
+opp_find_freq_floor - Search for an available OPP which is *at most* the
+ provided frequency. This function is useful while searching for a lesser
+ match OR operating on OPP information in the order of decreasing
+ frequency.
+ Example: To find the highest opp for a device:
+ freq = ULONG_MAX;
+ rcu_read_lock();
+ opp_find_freq_floor(dev, &freq);
+ rcu_read_unlock();
+
+opp_find_freq_ceil - Search for an available OPP which is *at least* the
+ provided frequency. This function is useful while searching for a
+ higher match OR operating on OPP information in the order of increasing
+ frequency.
+ Example 1: To find the lowest opp for a device:
+ freq = 0;
+ rcu_read_lock();
+ opp_find_freq_ceil(dev, &freq);
+ rcu_read_unlock();
+ Example 2: A simplified implementation of a SoC cpufreq_driver->target:
+ soc_cpufreq_target(..)
+ {
+ /* Do stuff like policy checks etc. */
+ /* Find the best frequency match for the req */
+ rcu_read_lock();
+ opp = opp_find_freq_ceil(dev, &freq);
+ rcu_read_unlock();
+ if (!IS_ERR(opp))
+ soc_switch_to_freq_voltage(freq);
+ else
+ /* do something when we cant satisfy the req */
+ /* do other stuff */
+ }
+
+4. OPP Availability Control Functions
+=====================================
+A default OPP list registered with the OPP library may not cater to all possible
+situation. The OPP library provides a set of functions to modify the
+availability of a OPP within the OPP list. This allows SoC frameworks to have
+fine grained dynamic control of which sets of OPPs are operationally available.
+These functions are intended to *temporarily* remove an OPP in conditions such
+as thermal considerations (e.g. don't use OPPx until the temperature drops).
+
+WARNING: Do not use these functions in interrupt context.
+
+opp_enable - Make a OPP available for operation.
+ Example: Lets say that 1GHz OPP is to be made available only if the
+ SoC temperature is lower than a certain threshold. The SoC framework
+ implementation might choose to do something as follows:
+ if (cur_temp < temp_low_thresh) {
+ /* Enable 1GHz if it was disabled */
+ rcu_read_lock();
+ opp = opp_find_freq_exact(dev, 1000000000, false);
+ rcu_read_unlock();
+ /* just error check */
+ if (!IS_ERR(opp))
+ ret = opp_enable(dev, 1000000000);
+ else
+ goto try_something_else;
+ }
+
+opp_disable - Make an OPP to be not available for operation
+ Example: Lets say that 1GHz OPP is to be disabled if the temperature
+ exceeds a threshold value. The SoC framework implementation might
+ choose to do something as follows:
+ if (cur_temp > temp_high_thresh) {
+ /* Disable 1GHz if it was enabled */
+ rcu_read_lock();
+ opp = opp_find_freq_exact(dev, 1000000000, true);
+ rcu_read_unlock();
+ /* just error check */
+ if (!IS_ERR(opp))
+ ret = opp_disable(dev, 1000000000);
+ else
+ goto try_something_else;
+ }
+
+5. OPP Data Retrieval Functions
+===============================
+Since OPP library abstracts away the OPP information, a set of functions to pull
+information from the OPP structure is necessary. Once an OPP pointer is
+retrieved using the search functions, the following functions can be used by SoC
+framework to retrieve the information represented inside the OPP layer.
+
+opp_get_voltage - Retrieve the voltage represented by the opp pointer.
+ Example: At a cpufreq transition to a different frequency, SoC
+ framework requires to set the voltage represented by the OPP using
+ the regulator framework to the Power Management chip providing the
+ voltage.
+ soc_switch_to_freq_voltage(freq)
+ {
+ /* do things */
+ rcu_read_lock();
+ opp = opp_find_freq_ceil(dev, &freq);
+ v = opp_get_voltage(opp);
+ rcu_read_unlock();
+ if (v)
+ regulator_set_voltage(.., v);
+ /* do other things */
+ }
+
+opp_get_freq - Retrieve the freq represented by the opp pointer.
+ Example: Lets say the SoC framework uses a couple of helper functions
+ we could pass opp pointers instead of doing additional parameters to
+ handle quiet a bit of data parameters.
+ soc_cpufreq_target(..)
+ {
+ /* do things.. */
+ max_freq = ULONG_MAX;
+ rcu_read_lock();
+ max_opp = opp_find_freq_floor(dev,&max_freq);
+ requested_opp = opp_find_freq_ceil(dev,&freq);
+ if (!IS_ERR(max_opp) && !IS_ERR(requested_opp))
+ r = soc_test_validity(max_opp, requested_opp);
+ rcu_read_unlock();
+ /* do other things */
+ }
+ soc_test_validity(..)
+ {
+ if(opp_get_voltage(max_opp) < opp_get_voltage(requested_opp))
+ return -EINVAL;
+ if(opp_get_freq(max_opp) < opp_get_freq(requested_opp))
+ return -EINVAL;
+ /* do things.. */
+ }
+
+opp_get_opp_count - Retrieve the number of available opps for a device
+ Example: Lets say a co-processor in the SoC needs to know the available
+ frequencies in a table, the main processor can notify as following:
+ soc_notify_coproc_available_frequencies()
+ {
+ /* Do things */
+ rcu_read_lock();
+ num_available = opp_get_opp_count(dev);
+ speeds = kzalloc(sizeof(u32) * num_available, GFP_KERNEL);
+ /* populate the table in increasing order */
+ freq = 0;
+ while (!IS_ERR(opp = opp_find_freq_ceil(dev, &freq))) {
+ speeds[i] = freq;
+ freq++;
+ i++;
+ }
+ rcu_read_unlock();
+
+ soc_notify_coproc(AVAILABLE_FREQs, speeds, num_available);
+ /* Do other things */
+ }
+
+6. Cpufreq Table Generation
+===========================
+opp_init_cpufreq_table - cpufreq framework typically is initialized with
+ cpufreq_frequency_table_cpuinfo which is provided with the list of
+ frequencies that are available for operation. This function provides
+ a ready to use conversion routine to translate the OPP layer's internal
+ information about the available frequencies into a format readily
+ providable to cpufreq.
+
+ WARNING: Do not use this function in interrupt context.
+
+ Example:
+ soc_pm_init()
+ {
+ /* Do things */
+ r = opp_init_cpufreq_table(dev, &freq_table);
+ if (!r)
+ cpufreq_frequency_table_cpuinfo(policy, freq_table);
+ /* Do other things */
+ }
+
+ NOTE: This function is available only if CONFIG_CPU_FREQ is enabled in
+ addition to CONFIG_PM as power management feature is required to
+ dynamically scale voltage and frequency in a system.
+
+7. Data Structures
+==================
+Typically an SoC contains multiple voltage domains which are variable. Each
+domain is represented by a device pointer. The relationship to OPP can be
+represented as follows:
+SoC
+ |- device 1
+ | |- opp 1 (availability, freq, voltage)
+ | |- opp 2 ..
+ ... ...
+ | `- opp n ..
+ |- device 2
+ ...
+ `- device m
+
+OPP library maintains a internal list that the SoC framework populates and
+accessed by various functions as described above. However, the structures
+representing the actual OPPs and domains are internal to the OPP library itself
+to allow for suitable abstraction reusable across systems.
+
+struct opp - The internal data structure of OPP library which is used to
+ represent an OPP. In addition to the freq, voltage, availability
+ information, it also contains internal book keeping information required
+ for the OPP library to operate on. Pointer to this structure is
+ provided back to the users such as SoC framework to be used as a
+ identifier for OPP in the interactions with OPP layer.
+
+ WARNING: The struct opp pointer should not be parsed or modified by the
+ users. The defaults of for an instance is populated by opp_add, but the
+ availability of the OPP can be modified by opp_enable/disable functions.
+
+struct device - This is used to identify a domain to the OPP layer. The
+ nature of the device and it's implementation is left to the user of
+ OPP library such as the SoC framework.
+
+Overall, in a simplistic view, the data structure operations is represented as
+following:
+
+Initialization / modification:
+ +-----+ /- opp_enable
+opp_add --> | opp | <-------
+ | +-----+ \- opp_disable
+ \-------> domain_info(device)
+
+Search functions:
+ /-- opp_find_freq_ceil ---\ +-----+
+domain_info<---- opp_find_freq_exact -----> | opp |
+ \-- opp_find_freq_floor ---/ +-----+
+
+Retrieval functions:
++-----+ /- opp_get_voltage
+| opp | <---
++-----+ \- opp_get_freq
+
+domain_info <- opp_get_opp_count

restore, and run-time resume, can achieve this with the help of the
UNIVERSAL_DEV_PM_OPS macro defined in include/linux/pm.h (possibly setting its
last argument to NULL).
+
+8. "No-Callback" Devices
+
+Some "devices" are only logical sub-devices of their parent and cannot be
+power-managed on their own. (The prototype example is a USB interface. Entire
+USB devices can go into low-power mode or send wake-up requests, but neither is
+possible for individual interfaces.) The drivers for these devices have no
+need of run-time PM callbacks; if the callbacks did exist, ->runtime_suspend()
+and ->runtime_resume() would always return 0 without doing anything else and
+->runtime_idle() would always call pm_runtime_suspend().
+
+Subsystems can tell the PM core about these devices by calling
+pm_runtime_no_callbacks(). This should be done after the device structure is
+initialized and before it is registered (although after device registration is
+also okay). The routine will set the device's power.no_callbacks flag and
+prevent the non-debugging run-time PM sysfs attributes from being created.
+
+When power.no_callbacks is set, the PM core will not invoke the
+->runtime_idle(), ->runtime_suspend(), or ->runtime_resume() callbacks.
+Instead it will assume that suspends and resumes always succeed and that idle
+devices should be suspended.
+
+As a consequence, the PM core will never directly inform the device's subsystem
+or driver about run-time power changes. Instead, the driver for the device's
+parent must take responsibility for telling the device's driver when the
+parent's power state changes.
+
+9. Autosuspend, or automatically-delayed suspends
+
+Changing a device's power state isn't free; it requires both time and energy.
+A device should be put in a low-power state only when there's some reason to
+think it will remain in that state for a substantial time. A common heuristic
+says that a device which hasn't been used for a while is liable to remain
+unused; following this advice, drivers should not allow devices to be suspended
+at run-time until they have been inactive for some minimum period. Even when
+the heuristic ends up being non-optimal, it will still prevent devices from
+"bouncing" too rapidly between low-power and full-power states.
+
+The term "autosuspend" is an historical remnant. It doesn't mean that the
+device is automatically suspended (the subsystem or driver still has to call
+the appropriate PM routines); rather it means that run-time suspends will
+automatically be delayed until the desired period of inactivity has elapsed.
+
+Inactivity is determined based on the power.last_busy field. Drivers should
+call pm_runtime_mark_last_busy() to update this field after carrying out I/O,
+typically just before calling pm_runtime_put_autosuspend(). The desired length
+of the inactivity period is a matter of policy. Subsystems can set this length
+initially by calling pm_runtime_set_autosuspend_delay(), but after device
+registration the length should be controlled by user space, using the
+/sys/devices/.../power/autosuspend_delay_ms attribute.
+
+In order to use autosuspend, subsystems or drivers must call
+pm_runtime_use_autosuspend() (preferably before registering the device), and
+thereafter they should use the various *_autosuspend() helper functions instead
+of the non-autosuspend counterparts:
+
+ Instead of: pm_runtime_suspend use: pm_runtime_autosuspend;
+ Instead of: pm_schedule_suspend use: pm_request_autosuspend;
+ Instead of: pm_runtime_put use: pm_runtime_put_autosuspend;
+ Instead of: pm_runtime_put_sync use: pm_runtime_put_sync_autosuspend.
+
+Drivers may also continue to use the non-autosuspend helper functions; they
+will behave normally, not taking the autosuspend delay into account.
+Similarly, if the power.use_autosuspend field isn't set then the autosuspend
+helper functions will behave just like the non-autosuspend counterparts.
+
+The implementation is well suited for asynchronous use in interrupt contexts.
+However such use inevitably involves races, because the PM core can't
+synchronize ->runtime_suspend() callbacks with the arrival of I/O requests.
+This synchronization must be handled by the driver, using its private lock.
+Here is a schematic pseudo-code example:
+
+ foo_read_or_write(struct foo_priv *foo, void *data)
+ {

+2. Why cmwq?
+3. The Design

+5. Example Execution Scenarios
+6. Guidelines
+
+
+1. Introduction
+
+There are many cases where an asynchronous process execution context
+is needed and the workqueue (wq) API is the most commonly used
+mechanism for such cases.
+
+When such an asynchronous execution context is needed, a work item
+describing which function to execute is put on a queue. An
+independent thread serves as the asynchronous execution context. The
+queue is called workqueue and the thread is called worker.
+
+While there are work items on the workqueue the worker executes the
+functions associated with the work items one after the other. When
+there is no work item left on the workqueue the worker becomes idle.
+When a new work item gets queued, the worker begins executing again.
+
+
+2. Why cmwq?
+
+In the original wq implementation, a multi threaded (MT) wq had one
+worker thread per CPU and a single threaded (ST) wq had one worker
+thread system-wide. A single MT wq needed to keep around the same
+number of workers as the number of CPUs. The kernel grew a lot of MT
+wq users over the years and with the number of CPU cores continuously
+rising, some systems saturated the default 32k PID space just booting
+up.
+
+Although MT wq wasted a lot of resource, the level of concurrency
+provided was unsatisfactory. The limitation was common to both ST and
+MT wq albeit less severe on MT. Each wq maintained its own separate
+worker pool. A MT wq could provide only one execution context per CPU
+while a ST wq one for the whole system. Work items had to compete for
+those very limited execution contexts leading to various problems
+including proneness to deadlocks around the single execution context.
+
+The tension between the provided level of concurrency and resource
+usage also forced its users to make unnecessary tradeoffs like libata
+choosing to use ST wq for polling PIOs and accepting an unnecessary
+limitation that no two polling PIOs can progress at the same time. As
+MT wq don't provide much better concurrency, users which require
+higher level of concurrency, like async or fscache, had to implement
+their own thread pool.
+
+Concurrency Managed Workqueue (cmwq) is a reimplementation of wq with
+focus on the following goals.
+
+* Maintain compatibility with the original workqueue API.
+
+* Use per-CPU unified worker pools shared by all wq to provide
+ flexible level of concurrency on demand without wasting a lot of
+ resource.
+
+* Automatically regulate worker pool and level of concurrency so that
+ the API users don't need to worry about such details.
+
+
+3. The Design
+
+In order to ease the asynchronous execution of functions a new
+abstraction, the work item, is introduced.
+
+A work item is a simple struct that holds a pointer to the function
+that is to be executed asynchronously. Whenever a driver or subsystem
+wants a function to be executed asynchronously it has to set up a work
+item pointing to that function and queue that work item on a
+workqueue.
+
+Special purpose threads, called worker threads, execute the functions
+off of the queue, one after the other. If no work is queued, the
+worker threads become idle. These worker threads are managed in so
+called thread-pools.
+
+The cmwq design differentiates between the user-facing workqueues that
+subsystems and drivers queue work items on and the backend mechanism
+which manages thread-pool and processes the queued work items.
+
+The backend is called gcwq. There is one gcwq for each possible CPU
+and one gcwq to serve work items queued on unbound workqueues.
+
+Subsystems and drivers can create and queue work items through special
+workqueue API functions as they see fit. They can influence some
+aspects of the way the work items are executed by setting flags on the
+workqueue they are putting the work item on. These flags include
+things like CPU locality, reentrancy, concurrency limits and more. To
+get a detailed overview refer to the API description of
+alloc_workqueue() below.
+
+When a work item is queued to a workqueue, the target gcwq is
+determined according to the queue parameters and workqueue attributes
+and appended on the shared worklist of the gcwq. For example, unless
+specifically overridden, a work item of a bound workqueue will be
+queued on the worklist of exactly that gcwq that is associated to the
+CPU the issuer is running on.
+
+For any worker pool implementation, managing the concurrency level
+(how many execution contexts are active) is an important issue. cmwq
+tries to keep the concurrency at a minimal but sufficient level.
+Minimal to save resources and sufficient in that the system is used at
+its full capacity.
+
+Each gcwq bound to an actual CPU implements concurrency management by
+hooking into the scheduler. The gcwq is notified whenever an active
+worker wakes up or sleeps and keeps track of the number of the
+currently runnable workers. Generally, work items are not expected to
+hog a CPU and consume many cycles. That means maintaining just enough
+concurrency to prevent work processing from stalling should be
+optimal. As long as there are one or more runnable workers on the
+CPU, the gcwq doesn't start execution of a new work, but, when the
+last running worker goes to sleep, it immediately schedules a new
+worker so that the CPU doesn't sit idle while there are pending work
+items. This allows using a minimal number of workers without losing
+execution bandwidth.
+
+Keeping idle workers around doesn't cost other than the memory space
+for kthreads, so cmwq holds onto idle ones for a while before killing
+them.
+
+For an unbound wq, the above concurrency management doesn't apply and
+the gcwq for the pseudo unbound CPU tries to start executing all work
+items as soon as possible. The responsibility of regulating
+concurrency level is on the users. There is also a flag to mark a
+bound wq to ignore the concurrency management. Please refer to the
+API section for details.
+
+Forward progress guarantee relies on that workers can be created when
+more execution contexts are necessary, which in turn is guaranteed
+through the use of rescue workers. All work items which might be used
+on code paths that handle memory reclaim are required to be queued on
+wq's that have a rescue-worker reserved for execution under memory
+pressure. Else it is possible that the thread-pool deadlocks waiting
+for execution contexts to free up.
+
+
+4. Application Programming Interface (API)
+
+alloc_workqueue() allocates a wq. The original create_*workqueue()
+functions are deprecated and scheduled for removal. alloc_workqueue()
+takes three arguments - @name, @flags and @max_active. @name is the
+name of the wq and also used as the name of the rescuer thread if
+there is one.
+
+A wq no longer manages execution resources but serves as a domain for
+forward progress guarantee, flush and work item attributes. @flags
+and @max_active control how work items are assigned execution
+resources, scheduled and executed.
+
+@flags:
+
+ WQ_NON_REENTRANT
+
+ By default, a wq guarantees non-reentrance only on the same
+ CPU. A work item may not be executed concurrently on the same
+ CPU by multiple workers but is allowed to be executed
+ concurrently on multiple CPUs. This flag makes sure
+ non-reentrance is enforced across all CPUs. Work items queued
+ to a non-reentrant wq are guaranteed to be executed by at most
+ one worker system-wide at any given time.
+
+ WQ_UNBOUND
+
+ Work items queued to an unbound wq are served by a special
+ gcwq which hosts workers which are not bound to any specific
+ CPU. This makes the wq behave as a simple execution context
+ provider without concurrency management. The unbound gcwq
+ tries to start execution of work items as soon as possible.
+ Unbound wq sacrifices locality but is useful for the following
+ cases.
+
+ * Wide fluctuation in the concurrency level requirement is
+ expected and using bound wq may end up creating large number
+ of mostly unused workers across different CPUs as the issuer
+ hops through different CPUs.
+
+ * Long running CPU intensive workloads which can be better
+ managed by the system scheduler.
+
+ WQ_FREEZEABLE
+
+ A freezeable wq participates in the freeze phase of the system
+ suspend operations. Work items on the wq are drained and no
+ new work item starts execution until thawed.
+
+ WQ_MEM_RECLAIM
+
+ All wq which might be used in the memory reclaim paths _MUST_
+ have this flag set. The wq is guaranteed to have at least one
+ execution context regardless of memory pressure.
+
+ WQ_HIGHPRI
+
+ Work items of a highpri wq are queued at the head of the
+ worklist of the target gcwq and start execution regardless of
+ the current concurrency level. In other words, highpri work
+ items will always start execution as soon as execution
+ resource is available.
+
+ Ordering among highpri work items is preserved - a highpri
+ work item queued after another highpri work item will start
+ execution after the earlier highpri work item starts.
+
+ Although highpri work items are not held back by other
+ runnable work items, they still contribute to the concurrency
+ level. Highpri work items in runnable state will prevent
+ non-highpri work items from starting execution.
+
+ This flag is meaningless for unbound wq.
+
+ WQ_CPU_INTENSIVE
+
+ Work items of a CPU intensive wq do not contribute to the
+ concurrency level. In other words, runnable CPU intensive
+ work items will not prevent other work items from starting
+ execution. This is useful for bound work items which are
+ expected to hog CPU cycles so that their execution is
+ regulated by the system scheduler.
+
+ Although CPU intensive work items don't contribute to the
+ concurrency level, start of their executions is still
+ regulated by the concurrency management and runnable
+ non-CPU-intensive work items can delay execution of CPU
+ intensive work items.
+
+ This flag is meaningless for unbound wq.
+
+ WQ_HIGHPRI | WQ_CPU_INTENSIVE
+
+ This combination makes the wq avoid interaction with
+ concurrency management completely and behave as a simple
+ per-CPU execution context provider. Work items queued on a
+ highpri CPU-intensive wq start execution as soon as resources
+ are available and don't affect execution of other work items.
+
+@max_active:
+
+@max_active determines the maximum number of execution contexts per
+CPU which can be assigned to the work items of a wq. For example,
+with @max_active of 16, at most 16 work items of the wq can be
+executing at the same time per CPU.
+
+Currently, for a bound wq, the maximum limit for @max_active is 512
+and the default value used when 0 is specified is 256. For an unbound
+wq, the limit is higher of 512 and 4 * num_possible_cpus(). These
+values are chosen sufficiently high such that they are not the
+limiting factor while providing protection in runaway cases.
+
+The number of active work items of a wq is usually regulated by the
+users of the wq, more specifically, by how many work items the users
+may queue at the same time. Unless there is a specific need for
+throttling the number of active work items, specifying '0' is
+recommended.
+
+Some users depend on the strict execution ordering of ST wq. The
+combination of @max_active of 1 and WQ_UNBOUND is used to achieve this
+behavior. Work items on such wq are always queued to the unbound gcwq
+and only one work item can be active at any given time thus achieving
+the same ordering property as ST wq.
+
+
+5. Example Execution Scenarios
+
+The following example execution scenarios try to illustrate how cmwq
+behave under different configurations.
+
+ Work items w0, w1, w2 are queued to a bound wq q0 on the same CPU.
+ w0 burns CPU for 5ms then sleeps for 10ms then burns CPU for 5ms
+ again before finishing. w1 and w2 burn CPU for 5ms then sleep for
+ 10ms.
+
+Ignoring all other tasks, works and processing overhead, and assuming
+simple FIFO scheduling, the following is one highly simplified version
+of possible sequences of events with the original wq.
+
+ TIME IN MSECS EVENT
+ 0 w0 starts and burns CPU
+ 5 w0 sleeps
+ 15 w0 wakes up and burns CPU
+ 20 w0 finishes
+ 20 w1 starts and burns CPU
+ 25 w1 sleeps
+ 35 w1 wakes up and finishes
+ 35 w2 starts and burns CPU
+ 40 w2 sleeps
+ 50 w2 wakes up and finishes
+
+And with cmwq with @max_active >= 3,
+
+ TIME IN MSECS EVENT
+ 0 w0 starts and burns CPU
+ 5 w0 sleeps
+ 5 w1 starts and burns CPU
+ 10 w1 sleeps
+ 10 w2 starts and burns CPU
+ 15 w2 sleeps
+ 15 w0 wakes up and burns CPU
+ 20 w0 finishes
+ 20 w1 wakes up and finishes
+ 25 w2 wakes up and finishes
+
+If @max_active == 2,
+
+ TIME IN MSECS EVENT
+ 0 w0 starts and burns CPU
+ 5 w0 sleeps
+ 5 w1 starts and burns CPU
+ 10 w1 sleeps
+ 15 w0 wakes up and burns CPU
+ 20 w0 finishes
+ 20 w1 wakes up and finishes
+ 20 w2 starts and burns CPU
+ 25 w2 sleeps
+ 35 w2 wakes up and finishes
+
+Now, let's assume w1 and w2 are queued to a different wq q1 which has
+WQ_HIGHPRI set,
+
+ TIME IN MSECS EVENT
+ 0 w1 and w2 start and burn CPU
+ 5 w1 sleeps
+ 10 w2 sleeps
+ 10 w0 starts and burns CPU
+ 15 w0 sleeps
+ 15 w1 wakes up and finishes
+ 20 w2 wakes up and finishes
+ 25 w0 wakes up and burns CPU
+ 30 w0 finishes
+
+If q1 has WQ_CPU_INTENSIVE set,
+
+ TIME IN MSECS EVENT
+ 0 w0 starts and burns CPU
+ 5 w0 sleeps
+ 5 w1 and w2 start and burn CPU
+ 10 w1 sleeps
+ 15 w2 sleeps
+ 15 w0 wakes up and burns CPU
+ 20 w0 finishes
+ 20 w1 wakes up and finishes
+ 25 w2 wakes up and finishes
+
+
+6. Guidelines
+
+* Do not forget to use WQ_MEM_RECLAIM if a wq may process work items
+ which are used during memory reclaim. Each wq with WQ_MEM_RECLAIM
+ set has an execution context reserved for it. If there is
+ dependency among multiple work items used during memory reclaim,
+ they should be queued to separate wq each with WQ_MEM_RECLAIM.
+
+* Unless strict ordering is required, there is no need to use ST wq.
+
+* Unless there is a specific need, using 0 for @max_active is
+ recommended. In most use cases, concurrency level usually stays
+ well under the default limit.
+
+* A wq serves as a domain for forward progress guarantee
+ (WQ_MEM_RECLAIM, flush and work item attributes. Work items which
+ are not involved in memory reclaim and don't need to be flushed as a
+ part of a group of work items, and don't require any special
+ attribute, can use one of the system wq. There is no difference in
+ execution characteristics between using a dedicated wq and a system
+ wq.
+
+* Unless work items are expected to consume a huge amount of CPU
+ cycles, using a bound wq is usually beneficial due to the increased
+ level of locality in wq operations and work item execution.

- * forces the transfer so we can rely on the comparison with

- *
- * That works fine on those ATI chipsets, but on newer Intel
- * chipsets (ICH9...) this triggers due to an erratum: Reading

- *
- * We restrict the read back to the affected ATI chipsets (set

+ * HPETs are a complete disaster. The compare register is
+ * based on a equal comparison and neither provides a less
+ * than or equal functionality (which would require to take
+ * the wraparound into account) nor a simple count down event
+ * mode. Further the write to the comparator register is
+ * delayed internally up to two HPET clock cycles in certain
+ * chipsets (ATI, ICH9,10). We worked around that by reading
+ * back the compare register, but that required another
+ * workaround for ICH9,10 chips where the first readout after
+ * write can return the old stale value. We already have a
+ * minimum delta of 5us enforced, but a NMI or SMI hitting
+ * between the counter readout and the comparator write can
+ * move us behind that point easily. Now instead of reading
+ * the compare register back several times, we make the ETIME

+ *
+ * There are 3 objects defined in in this class:
+ * - ata_port
+ * - ata_link
+ * - ata_device
+ * Each port has a link object. Each link can have up to two devices for PATA
+ * and generally one for SATA.
+ * If there is SATA port multiplier [PMP], 15 additional ata_link object are
+ * created.
+ *
+ * These objects are created when the ata host is initialized and when a PMP is
+ * found. They are removed only when the HBA is removed, cleaned before the
+ * error handler runs.

+
+
+ Instructions for use
+ --------------------
+
+ 1) Map a Linux block device to an existing rbd image.
+
+ Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
+
+ $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
+
+ The snapshot name can be "-" or omitted to map the image read/write.
+
+ 2) List all active blkdev<->object mappings.
+
+ In this example, we have performed step #1 twice, creating two blkdevs,
+ mapped to two separate rados objects in the rados rbd pool
+
+ $ cat /sys/class/rbd/list
+ #id major client_name pool name snap KB
+ 0 254 client4143 rbd foo - 1024000
+
+ The columns, in order, are:
+ - blkdev unique id
+ - blkdev assigned major
+ - rados client id
+ - rados pool name
+ - rados block device name
+ - mapped snapshot ("-" if none)
+ - device size in KB
+
+
+ 3) Create a snapshot.
+
+ Usage: <blkdev id> <snapname>
+
+ $ echo "0 mysnap" > /sys/class/rbd/snap_create
+
+
+ 4) Listing a snapshot.
+
+ $ cat /sys/class/rbd/snaps_list
+ #id snap KB
+ 0 - 1024000 (*)
+ 0 foo 1024000
+
+ The columns, in order, are:
+ - blkdev unique id
+ - snapshot name, '-' means none (active read/write version)
+ - size of device at time of snapshot
+ - the (*) indicates this is the active version
+
+ 5) Rollback to snapshot.
+
+ Usage: <blkdev id> <snapname>
+
+ $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
+
+
+ 6) Mapping an image using snapshot.
+
+ A snapshot mapping is read-only. This is being done by passing
+ snap=<snapname> to the options when adding a device.
+
+ $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
+
+
+ 7) Remove an active blkdev<->rbd image mapping.
+
+ In this example, we remove the mapping with blkdev unique id 1.
+
+ $ echo 1 > /sys/class/rbd/remove
+
+
+ NOTE: The actual creation and deletion of rados objects is outside the scope
+ of this driver.

+ * scanning, such PEBs are put to the @corr list and UBI preserves them.
+ * Obviously, this lessens the amount of available PEBs, and if at some
+ * point UBI runs out of free PEBs, it switches to R/O mode. UBI also loudly
+ * informs about such PEBs every time the MTD device is attached.
+ *
+ * However, it is difficult to reliably distinguish between these types of

+ * header is corrupted and the data area does not contain all 0xFFs, and there
+ * were not bit-flips or integrity errors while reading the data area. Otherwise
+ * UBI assumes (1.). The assumptions are:

- * - io-tag can be reused.
- *
- * BFA_IOIM_STS_SCSI_ERR : IO completed with scsi error.
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_HOST_ABORTED : IO was aborted successfully due to

- * - io-tag cannot be reused yet.
- *
- * BFI_IOIM_STS_ABORTED : IO was aborted successfully
- * internally by f/w.
- * - io-tag cannot be reused yet.
- *
- * BFI_IOIM_STS_TIMEDOUT : IO timedout and ABTS/RRQ is happening
- * in the firmware and
- * - io-tag cannot be reused yet.
- *
- * BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO
- * with sequence level error
- * logic and hence host needs to retry
- * this IO with a different IO tag
- * - io-tag cannot be used yet.
- *
- * BFI_IOIM_STS_NEXUS_ABORT : Second Level Error Recovery from host
- * is required because 2 consecutive ABTS
- * timedout and host needs logout and
- * re-login with the target
- * - io-tag cannot be used yet.
- *
- * BFI_IOIM_STS_UNDERRUN : IO completed with SCSI status good,
- * but the data tranferred is less than
- * the fcp data length in the command.
- * ex. SCSI INQUIRY where transferred
- * data length and residue count in FCP
- * response accounts for total fcp-dl
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_OVERRUN : IO completed with SCSI status good,
- * but the data transerred is more than
- * fcp data length in the command. ex.
- * TAPE IOs where blocks can of unequal
- * lengths.
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag
- * during abort process
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_PROTO_ERR : Firmware detected a protocol error.
- * ex target sent more data than
- * requested, or there was data frame
- * loss and other reasons
- * - io-tag cannot be used yet.
- *
- * BFI_IOIM_STS_DIF_ERR : Firwmare detected DIF error. ex: DIF
- * CRC err or Ref Tag err or App tag err.
- * - io-tag can be reused.
- *
- * BFA_IOIM_STS_TSK_MGT_ABORT : IO was aborted because of Task
- * Management command from the host
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_UTAG : Firmware does not know about this
- * io_tag.

+ low kernel memory footprint on smaller machines.
+
+ ( Sparse irqs can also be beneficial on NUMA boxes, as they spread
