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.

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.

This driver permits reading of the internal temperature sensor of AMD

All these processors have a sensor, but on older revisions of Family 10h

Due to technical reasons, the driver can detect only the mainboard's

The TOUCH and WIDTH parameters have a geometrical interpretation; imagine

looking through a window at someone gently holding a finger against the

glass. You will see two regions, one inner region consisting of the part
|
||||
of the finger actually touching the glass, and one outer region formed by
|

the perimeter of the finger. The diameter of the inner region is the
|
||||
ABS_MT_TOUCH_MAJOR, the diameter of the outer region is
|
||||
ABS_MT_WIDTH_MAJOR. Now imagine the person pressing the finger harder
|
||||
against the glass. The inner region will increase, and in general, the
|
||||
ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR, which is always smaller than
|
||||
unity, is related to the finger pressure. For pressure-based devices,
|
||||
ABS_MT_PRESSURE may be used to provide the pressure on the contact area

instead.

The ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a

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.

---------------------------

|

An arch may pass in a unique value (frame pointer) to both the entering and
|
||||
exiting of a function. On exit, the value is compared and if it does not
|
||||
match, then it will panic the kernel. This is largely a sanity check for bad
|
||||
code generation with gcc. If gcc for your port sanely updates the frame
|
||||
pointer under different opitmization levels, then ignore this option.
|
||||
|
||||
However, adding support for it isn't terribly difficult. In your assembly code
|
||||
that calls prepare_ftrace_return(), pass the frame pointer as the 3rd argument.
|
||||
Then in the C version of that function, do what the x86 port does and pass it
|
||||
along to ftrace_push_return_trace() instead of a stub value of 0.
|
||||
|
||||
Similarly, when you call ftrace_return_to_handler(), pass it the frame pointer.
