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.

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.

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
