Description:

Get/Set current ambient light zone. Reading returns
|
||||
integer between 1..5 (1 = daylight, 2 = bright, ..., 5 = dark).
|
||||
Writing a value between 1..5 forces the backlight controller
|
||||
to enter the corresponding ambient light zone.
|
||||
Writing 0 returns to normal/automatic ambient light level
|
||||
operation. The ambient light sensing feature on these devices
|
||||
is an extension to the API documented in
|
||||
Documentation/ABI/stable/sysfs-class-backlight.
|
||||
It can be enabled by writing the value stored in
|
||||
/sys/class/backlight/<backlight>/max_brightness to
|
||||
/sys/class/backlight/<backlight>/brightness.

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

There is one single entry point to the kernel, at the start

of the kernel image. That entry point supports two calling
|

conventions. A summary of the interface is described here. A full
|

description of the boot requirements is documented in
|
||||
Documentation/arm/Booting

to the kernel with a tagged list of predefined parameters.

||||
r1 : Machine type number
|

|
||||
r2 : Physical address of tagged list in system RAM
|

|
||||
b) Entry with a flattened device-tree block. Firmware loads the
|

physical address of the flattened device tree block (dtb) into r2,
|
||||
r1 is not used, but it is considered good practise to use a valid
|
||||
machine number as described in Documentation/arm/Booting.
|
||||
|
||||
r0 : 0
|
||||
|
||||
r1 : Valid machine type number. When using a device tree,
|
||||
a single machine type number will often be assigned to

represent a class or family of SoCs.

|
||||
r2 : physical pointer to the device-tree block
|
||||
(defined in chapter II) in RAM. Device tree can be located
|
||||
anywhere in system RAM, but it should be aligned on a 64 bit
|
||||
boundary.
|
||||
|
||||
The kernel will differentiate between ATAGS and device tree booting by
|
||||
reading the memory pointed to by r2 and looking for either the flattened
|

device tree block magic value (0xd00dfeed) or the ATAG_CORE value at

DMA Engine API Guide
|
||||
====================
|
||||
|
||||
Vinod Koul <vinod dot koul at intel.com>
|
||||
|
||||
NOTE: For DMA Engine usage in async_tx please see:
|
||||
Documentation/crypto/async-tx-api.txt
|
||||
|
||||
|
||||
Below is a guide to device driver writers on how to use the Slave-DMA API of the
|
||||
DMA Engine. This is applicable only for slave DMA usage only.
|
||||
|
||||
The slave DMA usage consists of following steps
|
||||
1. Allocate a DMA slave channel
|
||||
2. Set slave and controller specific parameters
|
||||
3. Get a descriptor for transaction
|
||||
4. Submit the transaction and wait for callback notification
|
||||
|
||||
1. Allocate a DMA slave channel
|
||||
Channel allocation is slightly different in the slave DMA context, client
|
||||
drivers typically need a channel from a particular DMA controller only and even
|
||||
in some cases a specific channel is desired. To request a channel
|
||||
dma_request_channel() API is used.
|
||||
|
||||
Interface:
|
||||
struct dma_chan *dma_request_channel(dma_cap_mask_t mask,
|
||||
dma_filter_fn filter_fn,
|
||||
void *filter_param);
|
||||
where dma_filter_fn is defined as:
|
||||
typedef bool (*dma_filter_fn)(struct dma_chan *chan, void *filter_param);
|
||||
|
||||
When the optional 'filter_fn' parameter is set to NULL dma_request_channel
|
||||
simply returns the first channel that satisfies the capability mask. Otherwise,
|
||||
when the mask parameter is insufficient for specifying the necessary channel,
|
||||
the filter_fn routine can be used to disposition the available channels in the
|
||||
system. The filter_fn routine is called once for each free channel in the
|
||||
system. Upon seeing a suitable channel filter_fn returns DMA_ACK which flags
|
||||
that channel to be the return value from dma_request_channel. A channel
|
||||
allocated via this interface is exclusive to the caller, until
|
||||
dma_release_channel() is called.
|
||||
|
||||
2. Set slave and controller specific parameters
|
||||
Next step is always to pass some specific information to the DMA driver. Most of
|
||||
the generic information which a slave DMA can use is in struct dma_slave_config.
|
||||
It allows the clients to specify DMA direction, DMA addresses, bus widths, DMA
|
||||
burst lengths etc. If some DMA controllers have more parameters to be sent then
|
||||
they should try to embed struct dma_slave_config in their controller specific
|
||||
structure. That gives flexibility to client to pass more parameters, if
|
||||
required.
|
||||
|
||||
Interface:
|
||||
int dmaengine_slave_config(struct dma_chan *chan,
|
||||
struct dma_slave_config *config)
|
||||
|
||||
3. Get a descriptor for transaction
|
||||
For slave usage the various modes of slave transfers supported by the
|
||||
DMA-engine are:
|
||||
slave_sg - DMA a list of scatter gather buffers from/to a peripheral
|
||||
dma_cyclic - Perform a cyclic DMA operation from/to a peripheral till the
|
||||
operation is explicitly stopped.
|
||||
The non NULL return of this transfer API represents a "descriptor" for the given
|
||||
transaction.
|
||||
|
||||
Interface:
|
||||
struct dma_async_tx_descriptor *(*chan->device->device_prep_dma_sg)(
|
||||
struct dma_chan *chan,
|
||||
struct scatterlist *dst_sg, unsigned int dst_nents,
|
||||
struct scatterlist *src_sg, unsigned int src_nents,
|
||||
unsigned long flags);
|
||||
struct dma_async_tx_descriptor *(*chan->device->device_prep_dma_cyclic)(
|
||||
struct dma_chan *chan, dma_addr_t buf_addr, size_t buf_len,
|
||||
size_t period_len, enum dma_data_direction direction);
|
||||
|
||||
4. Submit the transaction and wait for callback notification
|
||||
To schedule the transaction to be scheduled by dma device, the "descriptor"
|
||||
returned in above (3) needs to be submitted.
|
||||
To tell the dma driver that a transaction is ready to be serviced, the
|
||||
descriptor->submit() callback needs to be invoked. This chains the descriptor to
|
||||
the pending queue.
|
||||
The transactions in the pending queue can be activated by calling the
|
||||
issue_pending API. If channel is idle then the first transaction in queue is
|
||||
started and subsequent ones queued up.
|
||||
On completion of the DMA operation the next in queue is submitted and a tasklet
|
||||
triggered. The tasklet would then call the client driver completion callback
|
||||
routine for notification, if set.
|
||||
Interface:
|
||||
void dma_async_issue_pending(struct dma_chan *chan);
|
||||
|
||||
==============================================================================
|
||||
|
||||
Additional usage notes for dma driver writers
|
||||
1/ Although DMA engine specifies that completion callback routines cannot submit
|
||||
any new operations, but typically for slave DMA subsequent transaction may not
|
||||
be available for submit prior to callback routine being called. This requirement
|
||||
is not a requirement for DMA-slave devices. But they should take care to drop
|
||||
the spin-lock they might be holding before calling the callback routine

Acer Laptop WMI Extras Driver
|
||||
http://code.google.com/p/aceracpi
|
||||
Version 0.3
|
||||
4th April 2009
|
||||
|
||||
Copyright 2007-2009 Carlos Corbacho <carlos@strangeworlds.co.uk>
|
||||
|
||||
acer-wmi is a driver to allow you to control various parts of your Acer laptop
|
||||
hardware under Linux which are exposed via ACPI-WMI.
|
||||
|
||||
This driver completely replaces the old out-of-tree acer_acpi, which I am
|
||||
currently maintaining for bug fixes only on pre-2.6.25 kernels. All development
|
||||
work is now focused solely on acer-wmi.
|
||||
|
||||
Disclaimer
|
||||
**********
|
||||
|
||||
Acer and Wistron have provided nothing towards the development acer_acpi or
|
||||
acer-wmi. All information we have has been through the efforts of the developers
|
||||
and the users to discover as much as possible about the hardware.
|
||||
|
||||
As such, I do warn that this could break your hardware - this is extremely
|
||||
unlikely of course, but please bear this in mind.
|
||||
|
||||
Background
|
||||
**********
|
||||
|
||||
acer-wmi is derived from acer_acpi, originally developed by Mark
|
||||
Smith in 2005, then taken over by Carlos Corbacho in 2007, in order to activate
|
||||
the wireless LAN card under a 64-bit version of Linux, as acerhk[1] (the
|
||||
previous solution to the problem) relied on making 32 bit BIOS calls which are
|
||||
not possible in kernel space from a 64 bit OS.

||||

|
||||
Supported Hardware
|
||||
******************
|
||||
|
||||
NOTE: The Acer Aspire One is not supported hardware. It cannot work with
|
||||
acer-wmi until Acer fix their ACPI-WMI implementation on them, so has been
|
||||
blacklisted until that happens.
|
||||
|
||||
Please see the website for the current list of known working hardware:
|
||||
|
||||
http://code.google.com/p/aceracpi/wiki/SupportedHardware
|
||||
|
||||
If your laptop is not listed, or listed as unknown, and works with acer-wmi,
|
||||
please contact me with a copy of the DSDT.
|
||||
|
||||
If your Acer laptop doesn't work with acer-wmi, I would also like to see the
|
||||
DSDT.
|
||||
|
||||
To send me the DSDT, as root/sudo:
|
||||
|
||||
cat /sys/firmware/acpi/tables/DSDT > dsdt
|
||||
|
||||
And send me the resulting 'dsdt' file.
|
||||
|
||||
Usage
|
||||
*****
|
||||
|
||||
On Acer laptops, acer-wmi should already be autoloaded based on DMI matching.
|
||||
For non-Acer laptops, until WMI based autoloading support is added, you will
|
||||
need to manually load acer-wmi.
|
||||
|
||||
acer-wmi creates /sys/devices/platform/acer-wmi, and fills it with various
|
||||
files whose usage is detailed below, which enables you to control some of the
|
||||
following (varies between models):
|
||||
|
||||
* the wireless LAN card radio
|
||||
* inbuilt Bluetooth adapter
|
||||
* inbuilt 3G card
|
||||
* mail LED of your laptop
|
||||
* brightness of the LCD panel
|
||||
|
||||
Wireless
|
||||
********
|
||||
|
||||
With regards to wireless, all acer-wmi does is enable the radio on the card. It
|
||||
is not responsible for the wireless LED - once the radio is enabled, this is
|
||||
down to the wireless driver for your card. So the behaviour of the wireless LED,
|
||||
once you enable the radio, will depend on your hardware and driver combination.
|
||||
|
||||
e.g. With the BCM4318 on the Acer Aspire 5020 series:
|
||||
|
||||
ndiswrapper: Light blinks on when transmitting
|
||||
b43: Solid light, blinks off when transmitting
|
||||
|
||||
Wireless radio control is unconditionally enabled - all Acer laptops that support
|
||||
acer-wmi come with built-in wireless. However, should you feel so inclined to
|
||||
ever wish to remove the card, or swap it out at some point, please get in touch
|
||||
with me, as we may well be able to gain some data on wireless card detection.
|
||||
|
||||
The wireless radio is exposed through rfkill.
|
||||
|
||||
Bluetooth
|
||||
*********
|
||||
|
||||
For bluetooth, this is an internal USB dongle, so once enabled, you will get
|
||||
a USB device connection event, and a new USB device appears. When you disable
|
||||
bluetooth, you get the reverse - a USB device disconnect event, followed by the
|
||||
device disappearing again.
|
||||
|
||||
Bluetooth is autodetected by acer-wmi, so if you do not have a bluetooth module
|
||||
installed in your laptop, this file won't exist (please be aware that it is
|
||||
quite common for Acer not to fit bluetooth to their laptops - so just because
|
||||
you have a bluetooth button on the laptop, doesn't mean that bluetooth is
|
||||
installed).
|
||||
|
||||
For the adventurously minded - if you want to buy an internal bluetooth
|
||||
module off the internet that is compatible with your laptop and fit it, then

3G
|

**
|
||||
|
||||
3G is currently not autodetected, so the 'threeg' file is always created under
|
||||
sysfs. So far, no-one in possession of an Acer laptop with 3G built-in appears to
|
||||
have tried Linux, or reported back, so we don't have any information on this.
|
||||
|
||||
If you have an Acer laptop that does have a 3G card in, please contact me so we
|
||||
can properly detect these, and find out a bit more about them.
|
||||
|
||||
To read the status of the 3G card (0=off, 1=on):
|
||||
cat /sys/devices/platform/acer-wmi/threeg
|
||||
|
||||
To enable the 3G card:
|
||||
echo 1 > /sys/devices/platform/acer-wmi/threeg
|
||||
|
||||
To disable the 3G card:
|
||||
echo 0 > /sys/devices/platform/acer-wmi/threeg
|
||||
|
||||
To set the state of the 3G card when loading acer-wmi, pass:
|
||||
threeg=X (where X is 0 or 1)
|
||||

||||
Mail LED
|
||||
********
|
||||
|
||||
This can be found in most older Acer laptops supported by acer-wmi, and many
|
||||
newer ones - it is built into the 'mail' button, and blinks when active.
|
||||
|
||||
On newer (WMID) laptops though, we have no way of detecting the mail LED. If
|
||||
your laptop identifies itself in dmesg as a WMID model, then please try loading
|
||||
acer_acpi with:
|
||||
|
||||
force_series=2490
|
||||
|
||||
This will use a known alternative method of reading/ writing the mail LED. If
|
||||
it works, please report back to me with the DMI data from your laptop so this
|
||||
can be added to acer-wmi.
|
||||
|
||||
The LED is exposed through the LED subsystem, and can be found in:
|
||||
|
||||
/sys/devices/platform/acer-wmi/leds/acer-wmi::mail/
|
||||
|
||||
The mail LED is autodetected, so if you don't have one, the LED device won't
|
||||
be registered.
|
||||
|
||||
Backlight
|
||||
*********
|
||||
|
||||
The backlight brightness control is available on all acer-wmi supported
|
||||
hardware. The maximum brightness level is usually 15, but on some newer laptops
|
||||
it's 10 (this is again autodetected).
|
||||

@ -520,59 +520,20 @@ Support for power domains is provided through the pwr_domain field of struct
|
|||
device. This field is a pointer to an object of type struct dev_power_domain,
|
||||
defined in include/linux/pm.h, providing a set of power management callbacks
|
||||
analogous to the subsystem-level and device driver callbacks that are executed
|
||||
for the given device during all power transitions, in addition to the respective
|
||||
subsystem-level callbacks. Specifically, the power domain "suspend" callbacks
|
||||
(i.e. ->runtime_suspend(), ->suspend(), ->freeze(), ->poweroff(), etc.) are
|
||||
executed after the analogous subsystem-level callbacks, while the power domain
|
||||
"resume" callbacks (i.e. ->runtime_resume(), ->resume(), ->thaw(), ->restore,
|
||||
etc.) are executed before the analogous subsystem-level callbacks. Error codes
|
||||
returned by the "suspend" and "resume" power domain callbacks are ignored.
|
||||
for the given device during all power transitions, instead of the respective
|
||||
subsystem-level callbacks. Specifically, if a device's pm_domain pointer is
|
||||
not NULL, the ->suspend() callback from the object pointed to by it will be
|
||||
executed instead of its subsystem's (e.g. bus type's) ->suspend() callback and
|
||||
anlogously for all of the remaining callbacks. In other words, power management
|
||||
domain callbacks, if defined for the given device, always take precedence over
|
||||
the callbacks provided by the device's subsystem (e.g. bus type).
|
||||
|
||||
Power domain ->runtime_idle() callback is executed before the subsystem-level
|
||||
->runtime_idle() callback and the result returned by it is not ignored. Namely,
|
||||
if it returns error code, the subsystem-level ->runtime_idle() callback will not
|
||||
be called and the helper function rpm_idle() executing it will return error
|
||||
code. This mechanism is intended to help platforms where saving device state
|
||||
is a time consuming operation and should only be carried out if all devices
|
||||
in the power domain are idle, before turning off the shared power resource(s).
|
||||
Namely, the power domain ->runtime_idle() callback may return error code until
|
||||
the pm_runtime_idle() helper (or its asychronous version) has been called for
|
||||
all devices in the power domain (it is recommended that the returned error code
|
||||
be -EBUSY in those cases), preventing the subsystem-level ->runtime_idle()
|
||||
callback from being run prematurely.
|
||||
|
||||
The support for device power domains is only relevant to platforms needing to
|
||||
use the same subsystem-level (e.g. platform bus type) and device driver power
|
||||
management callbacks in many different power domain configurations and wanting
|
||||
to avoid incorporating the support for power domains into the subsystem-level
|
||||
callbacks. The other platforms need not implement it or take it into account
|
||||
in any way.

System Devices
|
||||
--------------
|
||||
System devices (sysdevs) follow a slightly different API, which can be found in
|
||||
|
||||
include/linux/sysdev.h
|
||||
drivers/base/sys.c
|
||||
|
||||
System devices will be suspended with interrupts disabled, and after all other
|
||||
devices have been suspended. On resume, they will be resumed before any other
|
||||
devices, and also with interrupts disabled. These things occur in special
|
||||
"sysdev_driver" phases, which affect only system devices.
|
||||
|
||||
Thus, after the suspend_noirq (or freeze_noirq or poweroff_noirq) phase, when
|
||||
the non-boot CPUs are all offline and IRQs are disabled on the remaining online
|
||||
CPU, then a sysdev_driver.suspend phase is carried out, and the system enters a
|
||||
sleep state (or a system image is created). During resume (or after the image
|
||||
has been created or loaded) a sysdev_driver.resume phase is carried out, IRQs
|
||||
are enabled on the only online CPU, the non-boot CPUs are enabled, and the
|
||||
resume_noirq (or thaw_noirq or restore_noirq) phase begins.
|
||||
|
||||
Code to actually enter and exit the system-wide low power state sometimes
|
||||
involves hardware details that are only known to the boot firmware, and
|
||||
may leave a CPU running software (from SRAM or flash memory) that monitors
|
||||
the system and manages its wakeup sequence.
|
||||
The support for device power management domains is only relevant to platforms
|
||||
needing to use the same device driver power management callbacks in many
|
||||
different power domain configurations and wanting to avoid incorporating the
|
||||
support for power domains into subsystem-level callbacks, for example by
|
||||
modifying the platform bus type. Other platforms need not implement it or take
|
||||
it into account in any way.
