-Anticipatory IO scheduler
--------------------------
-Nick Piggin <piggin@cyberone.com.au> 13 Sep 2003
-
-Attention! Database servers, especially those using "TCQ" disks should
-investigate performance with the 'deadline' IO scheduler. Any system with high
-disk performance requirements should do so, in fact.
-
-If you see unusual performance characteristics of your disk systems, or you
-see big performance regressions versus the deadline scheduler, please email
-me. Database users don't bother unless you're willing to test a lot of patches
-from me ;) its a known issue.
-
-Also, users with hardware RAID controllers, doing striping, may find
-highly variable performance results with using the as-iosched. The
-as-iosched anticipatory implementation is based on the notion that a disk
-device has only one physical seeking head. A striped RAID controller
-actually has a head for each physical device in the logical RAID device.
-
-However, setting the antic_expire (see tunable parameters below) produces
-very similar behavior to the deadline IO scheduler.
-
-Selecting IO schedulers
------------------------
-Refer to Documentation/block/switching-sched.txt for information on
-selecting an io scheduler on a per-device basis.
-
-Anticipatory IO scheduler Policies
-----------------------------------
-The as-iosched implementation implements several layers of policies
-to determine when an IO request is dispatched to the disk controller.
-Here are the policies outlined, in order of application.
-
-1. one-way Elevator algorithm.
-
-The elevator algorithm is similar to that used in deadline scheduler, with
-the addition that it allows limited backward movement of the elevator
-(i.e. seeks backwards). A seek backwards can occur when choosing between
-two IO requests where one is behind the elevator's current position, and
-the other is in front of the elevator's position. If the seek distance to
-the request in back of the elevator is less than half the seek distance to
-the request in front of the elevator, then the request in back can be chosen.
-Backward seeks are also limited to a maximum of MAXBACK (1024*1024) sectors.
-This favors forward movement of the elevator, while allowing opportunistic
-"short" backward seeks.
-
-2. FIFO expiration times for reads and for writes.
-
-This is again very similar to the deadline IO scheduler. The expiration
-times for requests on these lists is tunable using the parameters read_expire
-and write_expire discussed below. When a read or a write expires in this way,
-the IO scheduler will interrupt its current elevator sweep or read anticipation
-to service the expired request.
-
-3. Read and write request batching
-
-A batch is a collection of read requests or a collection of write
-requests. The as scheduler alternates dispatching read and write batches
-to the driver. In the case a read batch, the scheduler submits read
-requests to the driver as long as there are read requests to submit, and
-the read batch time limit has not been exceeded (read_batch_expire).
-The read batch time limit begins counting down only when there are
-competing write requests pending.
-
-In the case of a write batch, the scheduler submits write requests to
-the driver as long as there are write requests available, and the
-write batch time limit has not been exceeded (write_batch_expire).
-However, the length of write batches will be gradually shortened
-when read batches frequently exceed their time limit.
-
-When changing between batch types, the scheduler waits for all requests
-from the previous batch to complete before scheduling requests for the
-next batch.
-
-The read and write fifo expiration times described in policy 2 above
-are checked only when in scheduling IO of a batch for the corresponding
-(read/write) type. So for example, the read FIFO timeout values are
-tested only during read batches. Likewise, the write FIFO timeout
-values are tested only during write batches. For this reason,
-it is generally not recommended for the read batch time
-to be longer than the write expiration time, nor for the write batch
-time to exceed the read expiration time (see tunable parameters below).
-
-When the IO scheduler changes from a read to a write batch,
-it begins the elevator from the request that is on the head of the
-write expiration FIFO. Likewise, when changing from a write batch to
-a read batch, scheduler begins the elevator from the first entry
-on the read expiration FIFO.
-
-4. Read anticipation.
-
-Read anticipation occurs only when scheduling a read batch.
-This implementation of read anticipation allows only one read request
-to be dispatched to the disk controller at a time. In
-contrast, many write requests may be dispatched to the disk controller
-at a time during a write batch. It is this characteristic that can make
-the anticipatory scheduler perform anomalously with controllers supporting
-TCQ, or with hardware striped RAID devices. Setting the antic_expire
-queue parameter (see below) to zero disables this behavior, and the
-anticipatory scheduler behaves essentially like the deadline scheduler.
-
-When read anticipation is enabled (antic_expire is not zero), reads
-are dispatched to the disk controller one at a time.
-At the end of each read request, the IO scheduler examines its next
-candidate read request from its sorted read list. If that next request
-is from the same process as the request that just completed,
-or if the next request in the queue is "very close" to the
-just completed request, it is dispatched immediately. Otherwise,
-statistics (average think time, average seek distance) on the process
-that submitted the just completed request are examined. If it seems
-likely that that process will submit another request soon, and that
-request is likely to be near the just completed request, then the IO
-scheduler will stop dispatching more read requests for up to (antic_expire)
-milliseconds, hoping that process will submit a new request near the one
-that just completed. If such a request is made, then it is dispatched
-immediately. If the antic_expire wait time expires, then the IO scheduler
-will dispatch the next read request from the sorted read queue.
-
-To decide whether an anticipatory wait is worthwhile, the scheduler
-maintains statistics for each process that can be used to compute
-mean "think time" (the time between read requests), and mean seek
-distance for that process. One observation is that these statistics
-are associated with each process, but those statistics are not associated
-with a specific IO device. So for example, if a process is doing IO
-on several file systems on separate devices, the statistics will be
-a combination of IO behavior from all those devices.
-
-
-Tuning the anticipatory IO scheduler
-------------------------------------
-When using 'as', the anticipatory IO scheduler there are 5 parameters under
-/sys/block/*/queue/iosched/. All are units of milliseconds.
-
-The parameters are:
-* read_expire
- Controls how long until a read request becomes "expired". It also controls the
- interval between which expired requests are served, so set to 50, a request
- might take anywhere < 100ms to be serviced _if_ it is the next on the
- expired list. Obviously request expiration strategies won't make the disk
- go faster. The result basically equates to the timeslice a single reader
- gets in the presence of other IO. 100*((seek time / read_expire) + 1) is
- very roughly the % streaming read efficiency your disk should get with
- multiple readers.
-
-* read_batch_expire
- Controls how much time a batch of reads is given before pending writes are
- served. A higher value is more efficient. This might be set below read_expire
- if writes are to be given higher priority than reads, but reads are to be
- as efficient as possible when there are no writes. Generally though, it
- should be some multiple of read_expire.
-
-* write_expire, and
-* write_batch_expire are equivalent to the above, for writes.
-
-* antic_expire
- Controls the maximum amount of time we can anticipate a good read (one
- with a short seek distance from the most recently completed request) before
- giving up. Many other factors may cause anticipation to be stopped early,
- or some processes will not be "anticipated" at all. Should be a bit higher
- for big seek time devices though not a linear correspondence - most
- processes have only a few ms thinktime.
-
-In addition to the tunables above there is a read-only file named est_time
-which, when read, will show:
-
- - The probability of a task exiting without a cooperating task
- submitting an anticipated IO.
-
- - The current mean think time.
-
- - The seek distance used to determine if an incoming IO is better.

+ and pwm1_auto_point2_pwm. Read it out after
+ writing to get actual value.
+
+
+Module parameters
+-----------------
+
+If your board has a BIOS that initializes the amc6821 correctly, you should
+load the module with: init=0.
+
+If your board BIOS doesn't initialize the chip, or you want
+different settings, you can set the following parameters:
+init=1,
+pwminv: 0 default pwm output, 1 inverts pwm output.

+Description
+-----------
+
+This driver permits reading of the internal temperature sensor of AMD
+Family 10h and 11h processors.
+
+All these processors have a sensor, but on those for Socket F or AM2+,
+the sensor may return inconsistent values (erratum 319). The driver
+will refuse to load on these revisions unless you specify the "force=1"
+module parameter.
+
+Due to technical reasons, the driver can detect only the mainboard's
+socket type, not the processor's actual capabilities. Therefore, if you
+are using an AM3 processor on an AM2+ mainboard, you can safely use the
+"force=1" parameter.
+
+There is one temperature measurement value, available as temp1_input in
+sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
+Please note that it is defined as a relative value; to quote the AMD manual:
+
+ Tctl is the processor temperature control value, used by the platform to
+ control cooling systems. Tctl is a non-physical temperature on an
+ arbitrary scale measured in degrees. It does _not_ represent an actual
+ physical temperature like die or case temperature. Instead, it specifies
+ the processor temperature relative to the point at which the system must
+ supply the maximum cooling for the processor's specified maximum case
+ temperature and maximum thermal power dissipation.
+
+The maximum value for Tctl is available in the file temp1_max.
+
+If the BIOS has enabled hardware temperature control, the threshold at
+which the processor will throttle itself to avoid damage is available in
+temp1_crit and temp1_crit_hyst.

Software volume control should be done only in the main AC97/HDA
mixer.
-This feature allows volume control on ThinkPad models with a digital
-volume knob (when available, not all models have it), as well as
-mute/unmute control. The available commands are:
+
+About the ThinkPad Console Audio control:
+
+ThinkPads have a built-in amplifier and muting circuit that drives the
+console headphone and speakers. This circuit is after the main AC97
+or HDA mixer in the audio path, and under exclusive control of the
+firmware.
+
+ThinkPads have three special hotkeys to interact with the console
+audio control: volume up, volume down and mute.
+
+It is worth noting that the normal way the mute function works (on
+ThinkPads that do not have a "mute LED") is:
+
+1. Press mute to mute. It will *always* mute, you can press it as
+ many times as you want, and the sound will remain mute.
+
+2. Press either volume key to unmute the ThinkPad (it will _not_
+ change the volume, it will just unmute).
+
+This is a very superior design when compared to the cheap software-only
+mute-toggle solution found on normal consumer laptops: you can be
+absolutely sure the ThinkPad will not make noise if you press the mute
+button, no matter the previous state.
+
+The IBM ThinkPads, and the earlier Lenovo ThinkPads have variable-gain
+amplifiers driving the speakers and headphone output, and the firmware
+also handles volume control for the headphone and speakers on these
+ThinkPads without any help from the operating system (this volume
+control stage exists after the main AC97 or HDA mixer in the audio
+path).
+
+The newer Lenovo models only have firmware mute control, and depend on
+the main HDA mixer to do volume control (which is done by the operating
+system). In this case, the volume keys are filtered out for unmute
+key press (there are some firmware bugs in this area) and delivered as
+normal key presses to the operating system (thinkpad-acpi is not
+involved).
+
+
+The ThinkPad-ACPI volume control:
+
+The preferred way to interact with the Console Audio control is the
+ALSA interface.
+
+The legacy procfs interface allows one to read the current state,
+and if volume control is enabled, accepts the following commands:
echo up >/proc/acpi/ibm/volume
echo down >/proc/acpi/ibm/volume

+6. Run-time PM and System Sleep
+
+Run-time PM and system sleep (i.e., system suspend and hibernation, also known
+as suspend-to-RAM and suspend-to-disk) interact with each other in a couple of
+ways. If a device is active when a system sleep starts, everything is
+straightforward. But what should happen if the device is already suspended?
+
+The device may have different wake-up settings for run-time PM and system sleep.
+For example, remote wake-up may be enabled for run-time suspend but disallowed
+for system sleep (device_may_wakeup(dev) returns 'false'). When this happens,
+the subsystem-level system suspend callback is responsible for changing the
+device's wake-up setting (it may leave that to the device driver's system
+suspend routine). It may be necessary to resume the device and suspend it again
+in order to do so. The same is true if the driver uses different power levels
+or other settings for run-time suspend and system sleep.
+
+During system resume, devices generally should be brought back to full power,
+even if they were suspended before the system sleep began. There are several
+reasons for this, including:
+
+ * The device might need to switch power levels, wake-up settings, etc.
+
+ * Remote wake-up events might have been lost by the firmware.
+
+ * The device's children may need the device to be at full power in order
+ to resume themselves.
+
+ * The driver's idea of the device state may not agree with the device's
+ physical state. This can happen during resume from hibernation.
+
+ * The device might need to be reset.
+
+ * Even though the device was suspended, if its usage counter was > 0 then most
+ likely it would need a run-time resume in the near future anyway.
+
+ * Always going back to full power is simplest.
+
+If the device was suspended before the sleep began, then its run-time PM status
+will have to be updated to reflect the actual post-system sleep status. The way
+to do this is:
+
+ pm_runtime_disable(dev);
+ pm_runtime_set_active(dev);
+ pm_runtime_enable(dev);
+
+The PM core always increments the run-time usage counter before calling the
+->prepare() callback and decrements it after calling the ->complete() callback.
+Hence disabling run-time PM temporarily like this will not cause any run-time
+suspend callbacks to be lost.

+* OpenPIC and its interrupt numbers on Freescale's e500/e600 cores
+
+The OpenPIC specification does not specify which interrupt source has to
+become which interrupt number. This is up to the software implementation
+of the interrupt controller. The only requirement is that every
+interrupt source has to have an unique interrupt number / vector number.
+To accomplish this the current implementation assigns the number zero to
+the first source, the number one to the second source and so on until
+all interrupt sources have their unique number.
+Usually the assigned vector number equals the interrupt number mentioned
+in the documentation for a given core / CPU. This is however not true
+for the e500 cores (MPC85XX CPUs) where the documentation distinguishes
+between internal and external interrupt sources and starts counting at
+zero for both of them.
+
+So what to write for external interrupt source X or internal interrupt
+source Y into the device tree? Here is an example:
+
+The memory map for the interrupt controller in the MPC8544[0] shows,
+that the first interrupt source starts at 0x5_0000 (PIC Register Address
+Map-Interrupt Source Configuration Registers). This source becomes the
+number zero therefore:
+ External interrupt 0 = interrupt number 0
+ External interrupt 1 = interrupt number 1
+ External interrupt 2 = interrupt number 2
+ ...
+Every interrupt number allocates 0x20 bytes register space. So to get
+its number it is sufficient to shift the lower 16bits to right by five.
+So for the external interrupt 10 we have:
+ 0x0140 >> 5 = 10
+
+After the external sources, the internal sources follow. The in core I2C
+controller on the MPC8544 for instance has the internal source number
+27. Oo obtain its interrupt number we take the lower 16bits of its memory
+address (0x5_0560) and shift it right:
+ 0x0560 >> 5 = 43
+
+Therefore the I2C device node for the MPC8544 CPU has to have the
+interrupt number 43 specified in the device tree.

+ * Generates an Ethernet MAC address that is highly likely to be unique for
+ * this particular system on a network with other systems of the same type.
+ *
+ * The problem we are solving is that, when random_ether_addr() is used to
+ * generate MAC addresses at startup, there isn't much entropy for the random
+ * number generator to use and the addresses it produces are fairly likely to
+ * be the same as those of other identical systems on the same local network.
+ * This is true even for relatively small numbers of systems (for the reason
+ * why, see the Wikipedia entry for "Birthday problem" at:
+ * http://en.wikipedia.org/wiki/Birthday_problem
+ *
+ * The good news is that we already have a MAC address known to be unique, the
+ * RF MAC address. The bad news is that this address is already in use on the
+ * RF interface. Worse, the obvious trick, taking the RF MAC address and
+ * turning on the locally managed bit, has already been used for other devices.
+ * Still, this does give us something to work with.
+ *
+ * The approach we take is:
+ * 1. If we can't get the RF MAC Address, just call random_ether_addr.
+ * 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
+ * bits of the new address. This is very likely to be unique, except for
+ * the current box.
+ * 3. To avoid using addresses already on the current box, we set the top
+ * six bits of the address with a value different from any currently
+ * registered Scientific Atlanta organizationally unique identifyer
+ * (OUI). This avoids duplication with any addresses on the system that
+ * were generated from valid Scientific Atlanta-registered address by
+ * simply flipping the locally managed bit.
+ * 4. We aren't generating a multicast address, so we leave the multicast
+ * bit off. Since we aren't using a registered address, we have to set
+ * the locally managed bit.
+ * 5. We then randomly generate the remaining 16-bits. This does two
+ * things:
+ * a. It allows us to call this function for more than one device
+ * in this system
+ * b. It ensures that things will probably still work even if
+ * some device on the device network has a locally managed
+ * address that matches the top six bits from step 2.

*
* Description:
- * Merges two queue_limit structs. Returns 0 if alignment didn't
- * change. Returns -1 if adding the bottom device caused
- * misalignment.
+ * This function is used by stacking drivers like MD and DM to ensure
+ * that all component devices have compatible block sizes and
+ * alignments. The stacking driver must provide a queue_limits
+ * struct (top) and then iteratively call the stacking function for
+ * all component (bottom) devices. The stacking function will
+ * attempt to combine the values and ensure proper alignment.
+ *
+ * Returns 0 if the top and bottom queue_limits are compatible. The
+ * top device's block sizes and alignment offsets may be adjusted to
+ * ensure alignment with the bottom device. If no compatible sizes
+ * and alignments exist, -1 is returned and the resulting top
+ * queue_limits will have the misaligned flag set to indicate that

+/* NVIDIA context programs handle a number of other conditions which are
+ * not implemented in our versions. It's not clear why NVIDIA context
+ * programs have this code, nor whether it's strictly necessary for
+ * correct operation. We'll implement additional handling if/when we
+ * discover it's necessary.
+ *
+ * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state"
+ * flag is set, this gets saved into the context.
+ * - On context save, the context program for all cards load nsource
+ * into a flag register and check for ILLEGAL_MTHD. If it's set,
+ * opcode 0x60000d is called before resuming normal operation.
+ * - Some context programs check more conditions than the above. NV44
+ * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001))
+ * and calls 0x60000d before resuming normal operation.
+ * - At the very beginning of NVIDIA's context programs, flag 9 is checked
+ * and if true 0x800001 is called with count=0, pos=0, the flag is cleared
+ * and then the ctxprog is aborted. It looks like a complicated NOP,
+ * its purpose is unknown.
+ * - In the section of code that loads the per-vs state, NVIDIA check
+ * flag 10. If it's set, they only transfer the small 0x300 byte block
+ * of state + the state for a single vs as opposed to the state for
+ * all vs units. It doesn't seem likely that it'll occur in normal
+ * operation, especially seeing as it appears NVIDIA may have screwed
+ * up the ctxprogs for some cards and have an invalid instruction
+ * rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
+ * - There's a number of places where context offset 0 (where we place
+ * the PRAMIN offset of the context) is loaded into either 0x408000,
+ * 0x408004 or 0x408008. Not sure what's up there either.
+ * - The ctxprogs for some cards save 0x400a00 again during the cleanup
+ * path for auto-loadctx.

-config DST
- tristate "Distributed storage"
- depends on NET && CRYPTO && SYSFS && BLK_DEV
- select CONNECTOR
- ---help---
- DST is a network block device storage, which can be used to organize
- exported storage on the remote nodes into the local block device.
-
- DST works on top of any network media and protocol; it is just a matter
- of configuration utility to understand the correct addresses. The most
- common example is TCP over IP, which allows to pass through firewalls and
- create remote backup storage in a different datacenter. DST requires
- single port to be enabled on the exporting node and outgoing connections
- on the local node.
-
- DST works with in-kernel client and server, which improves performance by
- eliminating unneded data copies and by not depending on the version
- of the external IO components. It requires userspace configuration utility
- though.
-
- DST uses transaction model, when each store has to be explicitly acked
- from the remote node to be considered as successfully written. There
- may be lots of in-flight transactions. When remote host does not ack
- the transaction it will be resent predefined number of times with specified
- timeouts between them. All those parameters are configurable. Transactions
- are marked as failed after all resends complete unsuccessfully; having
- long enough resend timeout and/or large number of resends allows not to
- return error to the higher (FS usually) layer in case of short network
- problems or remote node outages. In case of network RAID setup this means
- that storage will not degrade until transactions are marked as failed, and
- thus will not force checksum recalculation and data rebuild. In case of
- connection failure DST will try to reconnect to the remote node automatically.
- DST sends ping commands at idle time to detect if remote node is alive.
-
- Because of transactional model it is possible to use zero-copy sending
- without worry of data corruption (which in turn could be detected by the
- strong checksums though).
-
- DST may fully encrypt the data channel in case of untrusted channel and implement
- strong checksum of the transferred data. It is possible to configure algorithms
- and crypto keys; they should match on both sides of the network channel.
- Crypto processing does not introduce noticeble performance overhead, since DST
- uses configurable pool of threads to perform crypto processing.
-
- DST utilizes memory pool model of all its transaction allocations (it is the
- only additional allocation on the client) and server allocations (bio pools,
- while pages are allocated from the slab).
-
- At startup DST performs a simple negotiation with the export node to determine
- access permissions and size of the exported storage. It can be extended if
- new parameters should be autonegotiated.
-
- DST carries block IO flags in the protocol, which allows to transparently implement
- barriers and sync/flush operations. Those flags are used in the export node where
- IO against the local storage is performed, which means that sync write will be sync
- on the remote node too, which in turn improves data integrity and improved resistance
- to errors and data corruption during power outages or storage damages.
