Description:
|
||||
Each USB device directory will contain a file named
|
||||
power/level. This file holds a power-level setting for
|
||||
the device, one of "on", "auto", or "suspend".
|
||||
the device, either "on" or "auto".
|
||||
|
||||
"on" means that the device is not allowed to autosuspend,
|
||||
although normal suspends for system sleep will still
|
||||
be honored. "auto" means the device will autosuspend
|
||||
and autoresume in the usual manner, according to the
|
||||
capabilities of its driver. "suspend" means the device
|
||||
is forced into a suspended state and it will not autoresume
|
||||
in response to I/O requests. However remote-wakeup requests
|
||||
from the device may still be enabled (the remote-wakeup
|
||||
setting is controlled separately by the power/wakeup

||||
attribute).

level. The "on" level is meant for administrative uses.
|
||||
If you want to suspend a device immediately but leave it
|

free to wake up in response to I/O requests, you should
|
||||
write "0" to power/autosuspend.
|
||||
|
||||
Device not capable of proper suspend and resume should be
|
||||
left in the "on" level. Although the USB spec requires
|
||||
devices to support suspend/resume, many of them do not.
|
||||
In fact so many don't that by default, the USB core

||||
initializes all non-hub devices in the "on" level. Some
|
||||
drivers may change this setting when they are bound.

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.

Description
|
||||
-----------
|
||||
|
||||
This driver implements support for the Texas Instruments amc6821 chip.
|
||||
The chip has one on-chip and one remote temperature sensor and one pwm fan
|
||||
regulator.
|
||||
The pwm can be controlled either from software or automatically.
|
||||
|
||||
The driver provides the following sensor accesses in sysfs:
|
||||
|
||||
temp1_input ro on-chip temperature
|
||||
temp1_min rw "
|
||||
temp1_max rw "

|
||||
|
||||
pwm1 rw pwm1
|
||||
pwm1_enable rw regulator mode, 1=open loop, 2=fan controlled
|
||||
by remote temperature, 3=fan controlled by
|
||||
combination of the on-chip temperature and
|
||||
remote-sensor temperature,
|
||||
pwm1_auto_channels_temp ro 1 if pwm_enable==2, 3 if pwm_enable==3
|
||||
pwm1_auto_point1_pwm ro Hardwired to 0, shared for both
|
||||
temperature channels.
|
||||
pwm1_auto_point2_pwm rw This value is shared for both temperature
|
||||
channels.
|
||||
pwm1_auto_point3_pwm rw Hardwired to 255, shared for both
|
||||
temperature channels.
|
||||
|
||||
temp1_auto_point1_temp ro Hardwired to temp2_auto_point1_temp
|
||||
which is rw. Below this temperature fan stops.
|
||||
temp1_auto_point2_temp rw The low-temperature limit of the proportional
|
||||
range. Below this temperature
|
||||
pwm1 = pwm1_auto_point2_pwm. It can go from
|
||||
0 degree C to 124 degree C in steps of
|
||||
4 degree C. Read it out after writing to get
|
||||
the actual value.
|
||||
temp1_auto_point3_temp rw Above this temperature fan runs at maximum
|
||||
speed. It can go from temp1_auto_point2_temp.
|
||||
It can only have certain discrete values
|
||||
which depend on temp1_auto_point2_temp and
|
||||
pwm1_auto_point2_pwm. Read it out after
|
||||
writing to get the actual value.
|
||||
|
||||
temp2_auto_point1_temp rw Must be between 0 degree C and 63 degree C and
|
||||
it defines the passive cooling temperature.
|
||||
Below this temperature the fan stops in
|
||||
the closed loop mode.
|
||||
temp2_auto_point2_temp rw The low-temperature limit of the proportional
|
||||
range. Below this temperature
|
||||
pwm1 = pwm1_auto_point2_pwm. It can go from
|
||||
0 degree C to 124 degree C in steps
|
||||
of 4 degree C.
|
||||
|
||||
temp2_auto_point3_temp rw Above this temperature fan runs at maximum
|
||||
speed. It can only have certain discrete
|
||||
values which depend on temp2_auto_point2_temp
|
||||
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
|

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.

Dynamic suspends can occur in two ways: manual and automatic.

whereas "automatic" means that the kernel has decided all by itself to

suspend a device. Automatic suspend is called "autosuspend" for
