[GIT PATCH] ACPI patches for 2.6.20-rc1
From: Len Brown
Date: Wed Dec 20 2006 - 04:35:59 EST
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
Highlights:
The Embedded Controller driver removes a GPE race condition.
Turns out we had been impatient with old machines, and
simply increasing an error timeout will make some of them work.
The platform specific drivers that use ACPI now send their
button events to the input layer.
Updated ibm-acpi driver from new sub-maintainer.
SGI is starting to leverage ACPI support, God bless them.
This will update the files shown below.
thanks!
-Len

ACPI: Add support for acpi_load_table/acpi_unload_table_id
Make acpi_load_table() available for use by removing it from the #ifdef
ACPI_FUTURE_USAGE.
Also add a new routine used to unload an ACPI table of a given type and "id" -
acpi_unload_table_id(). The implementation of this new routine was almost a
direct copy of existing routine acpi_unload_table() - only difference being
that it only removes a specific table id instead of ALL tables of a given
type. The SN hotplug driver (sgi_hotplug.c) now uses both of these interfaces
to dynamically load and unload SSDT ACPI tables.
Also, a few other ACPI routines now used by the SN hotplug driver are exported
(since the driver can be a loadable module):
acpi_ns_map_handle_to_node
acpi_ns_convert_entry_to_handle
acpi_ns_get_next_node

ACPI: video: Add dev argument for backlight_device_register
This patch set adds generic abstract layer support for acpi video driver to
have generic user interface to control backlight and output switch control by
leveraging the existing backlight sysfs class driver, and by adding a new
video output sysfs class driver.
This patch:
Add dev argument for backlight_device_register to link the class device to
real device object. The platform specific driver should find a way to get the
real device object for their video device.

commit f4715189dfb1c381ad36b7e02e3716fb7a7f84db
Author: Thomas Tuttle <linux-kernel@xxxxxxxxxxx>
Date: Tue Dec 19 12:56:14 2006 -0800
ACPI: Implement acpi_video_get_next_level()
acpi_video_get_next_level was supposed to implement an algorithm to select
a new brightness level based on the old brightness level of an ACPI video
device, but it simply says "/* Fix me */" and returns the current
brightness.
This patch implements acpi_video_get_next_level properly. It had to change
a few constants at the top of the file because they were (apparently)
wrong, but it appears to work on my Dell Inspiron e1405 (with BIOS A05
only--BIOS A04 doesn't seem to send ACPI video hotkey events).

ACPI: ibm-acpi: implement fan watchdog command
This patch implements a fan control safety watchdog, by request of the
authors of userspace fan control scripts.
When the watchdog timer expires, the equivalent action of a "fan enable"
command is executed. The watchdog timer is reset at every reception of a
fan control command that could change the state of the fan itself.
This command is meant to be used by userspace fan control daemons, to make
sure the fan is never left set to an unsafe level because of userspace
problems.
Users of the X31/X40/X41 "speed" command are on their own, the current
implementation of "speed" is just too incomplete to be used safely,
anyway. Better to never use it, and just use the "level" command instead.
The watchdog is programmed using echo "watchdog <number>" > fan, where
number is the number of seconds to wait before doing an "enable", and zero
disables the watchdog.

ACPI: ibm-acpi: workaround for EC 0x2f initialization bug
A few ThinkPads fail to initialize EC register 0x2f both in the EC
firmware and ACPI DSDT. If the BIOS and the ACPI DSDT also do not
initialize it, then the initial status of that register does not
correspond to reality.
On all reported buggy machines, EC 0x2f will read 0x07 (fan level 7) upon
cold boot, when the EC is actually in mode 0x80 (auto mode). Since
returning a text string ("unknown") would break a number of userspace
programs, instead we correct the reading for the most probably correct
answer, and return it is in auto mode.
The workaround flags the status and level as unknown on module load/kernel
boot, until we are certain at least one fan control command was issued,
either by us, or by something else.
We don't work around the bug by doing a "fan enable" at module
load/startup (which would initialize the EC register) because it is not
known if these ThinkPad ACPI DSDT might have set the fan to level 7
instead of "auto" (we don't know if they can do this or not) due to a
thermal condition, and we don't want to override that, should they be
capable of it.
We should be setting the workaround flag to "status known" upon resume, as
both reports and a exaustive search on the DSDT tables at acpi.sf.net show
that the DSDTs always enable the fan on resume, thus working around the
bug. But since we don't have suspend/resume handlers in ibm-acpi yet and
the "EC register 0x2f was modified" logic is likely to catch the change
anyway, we don't.

ACPI: ibm-acpi: Implement direct-ec-access thermal reading modes for up to 16 sensors
This patch extends ibm-acpi to support reading thermal sensors directly
through ACPI EC register access. It uses a DMI match to detect ThinkPads
with a new-style embedded controller, that are known to have forward-
compatible register maps and use 0x00 to fill in non-used registers and
export thermal sensors at EC offsets 0x78-7F and 0xC0-C7.
Direct ACPI EC register access is implemented for 8-sensor and 16-sensor
new-style ThinkPad controller firmwares as an experimental feature. The
code does some limited sanity checks on the temperatures read through EC
access, and will default to the old ACPI TMP0-7 mode if anything is amiss.
Userspace ABI is not changed for 8 sensors, but /proc/acpi/ibm/thermal is
extended for 16 sensors if the firmware supports 16 sensors.
A documentation update is also provided.
The information about the ThinkPad register map was determined by studying
ibm-acpi "ecdump" output from various ThinkPad models, submitted by
subscribers of the linux-thinkpad mailinglist. Futher information was
gathered from the DSDT tables, as they describe the EC register map in
recent ThinkPads.
DSDT source shows that TMP0-7 access and direct register access are
actually the same thing on these firmwares, but unfortunately IBM never
did update their DSDT EC register map to export TMP8-TMP15 for the second
range of sensors.

ACPI: uninline ACPI global locking functions
- Fixes a build problem with CONFIG_M386=y (include file dependencies get
messy).
- Share the implementation between x86 and x86_64
- These are too big to inline anyway.

ACPI: avoid gcc warnings in ACPI mutex debug code
32bit vs 64 bit issues. sizeof(sizeof) and sizeof(pointer) is variable,
but we're trying to print it as unsigned int or u32.
Casts to unsigned long are used because type acpi_thread_id can be any one of
typedef u64 acpi_native_uint;
typedef u32 acpi_native_uint;
typedef u16 acpi_native_uint;
#define acpi_thread_id struct task_struct *
