Subject: [GIT PATCH] ACPI patches for 2.6.28-rc0
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
i7300_idle driver is new to upstream
panasonic-laptop driver is new to upstream
bay driver is deleted, now handled by dock
ACPICA core updated to 20080926 release
ec driver includes a promising fix for multiple sightings
various bugfixes, including some that will also go into .27-stable etc.
I've merged your latest tree with this branch,
so this pull should be conflict-free.
This will update the files shown below.
thanks!

ACPI: hack around sysfs warning with link order
There exists the following warning message will appear after the
following commit is merged.
>commit f2e969acd6d5981e6b1272810002558650d0736e

>ACPI: Add "acpi.power_nocheck=1" to disable power state check in
power transition:
>WARNING: at linux-2.6/fs/sysfs/dir.c:463 sysfs_add_one+0x33/0x39()
>sysfs: duplicate filename 'acpi' can not be created
>kobject_add_internal failed for acpi with -EEXIST, don't try to register
things with the same name in the same directory
In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).
In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.
Of course the better solution is to fix it in generic param code related
with sysfs.

ACPICA: New: Validation for predefined ACPI methods/objects
Validates predefined ACPI objects that appear in the namespace,
at the time they are evaluated. The argument count and the type of
the returned object are validated. The purpose of this validation
is to detect problems with the BIOS-exposed predefined ACPI objects
before the results are returned to the ACPI-related drivers.

ACPI: thinkpad-acpi: attempt to preserve fan state on resume
Attempt to preserve fan state across sleep and hibernation if the fan
control mode is enabled.
For safety reasons, only the PWM OFF (fan at 100%) or maximum
closed-loop level (level 7) are preserved. If the fan state was set
to anything else, it will not be restored.
Also, should the fan be at PWM OFF mode at resume, it will be left at
that state (but this is extremely unlikely, no ThinkPad firmware was
ever reported to do this).
For reference, the known states used for fan control upon resume by
the firmware are either "auto" or "level 7" depending on whether the
laptop wakes due to normal conditions or a thermal emergency.

but functional, the device is valid and the children of this device
should be enumerated. It means that the device should be added to
linux acpi device tree. But the device driver for this device should not
be loaded.
The detailed info can be found in the section 6.3.7 of ACPI 3.0b spec.
_STA may return bit 0 clear (not present) with bit 3 set (device is
functional). This case is used to indicate a valid device for which no
device driver should be loaded (for example, a bridge device.).
Children of this device may be present and valid. OS should continue
enumeration below a device whose _STA returns this bit combination

ACPI: Add "acpi.power_nocheck=1" to disable power state check in power transition
Maybe the incorrect power state is returned on the bogus bios, which
is different with the real power state. For example: the bios returns D0
state and the real power state is D3. OS expects to set the device to D0
state. In such case if OS uses the power state returned by the BIOS and
checks the device power state very strictly in power transition, the device
can't be transited to the correct power state.
So the boot option of "acpi.power_nocheck=1" is added to avoid checking
the device power in the course of device power transition.

ACPI: replace AE_BAD_ADDRESS exception code with AE_ERROR

For linux, it's only used at wmi.c and acer-wmi.c.
I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code
has no special meaning. The parent functions just call AE_SUCCESS() or
AE_FAILURE() to check the return status.
So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.

ACPI suspend: Fix CONFIG_ACPI_SLEEP dependence and some compilation warnings
Initially CONFIG_PM_SLEEP was defined as
CONFIG_SUSPEND || CONFIG_HIBERNATION and some ACPI code, most
importantly the code in drivers/acpi/main.c, was written with this
assumption. Currently, however, CONFIG_PM_SLEEP is also set when
CONFIG_XEN_SAVE_RESTORE is set.
This causes some compilation warnings to appear in
drivers/acpi/main.c if both CONFIG_SUSPEND and CONFIG_HIBERNATION
are unset and CONFIG_PM_SLEEP is set (this was impossible before).
To fix this problem, redefine CONFIG_ACPI_SLEEP do depend directly
on CONFIG_SUSPEND || CONFIG_HIBERNATION, as originally intended, and
use it instead of CONFIG_PM_SLEEP in drivers/acpi/main.c, wherever
appropriate.
Additionally, move the acpi_target_sleep_state definition from under
the #ifdef to prevent compilation from failing in some cases.

ACPI: Ingore the RESET_REG_SUP bit when using ACPI reset mechanism
According to ACPI 3.0, FADT.flags.RESET_REG_SUP indicates
whether the ACPI reboot mechanism is supported.
However, some boxes have this bit clear, have a valid
ACPI_RESET_REG & RESET_VALUE, and ACPI reboot is the only
mechanism that works for them after S3.
This suggests that other operating systems may not be checking
the RESET_REG_SUP bit, and are using other means to decide
whether to use the ACPI reboot mechanism or not.
Here we stop checking RESET_REG_SUP.
Instead, When acpi reboot is requested,
only the reset_register is checked. If the following
conditions are met, it indicates that the reset register is supported.
a. reset_register is not zero
b. the access width is eight
c. the bit_offset is zero

For it is EC firmware that decides when the EC

anywhere in the neighborhood of the fake
override trip points. Beware.
note also that thermal.nocrt is already available

ACPI: Ignore AE_NOT_FOUND error of EC _REG method and continue to initialize EC
On some broken BIOS the ACPI object in EC _REG method can't be found in
ACPI namespace, which causes that the status code of AE_NOT_FOUND is returned by
the EC _REG object. In such case the EC device can't be initialized correctly,
which causes that battery/AC adapter can't work normally. As the EC address
space handler is not removed and the memory pointed by its input argument is
already free, sometimes the kernel will also be panic when EC internal register
is still accessed. But the windows can work well on such broken BIOS.
Maybe it will be reasonable that OS ignores the AE_NOT_FOUND error
returned by the EC _REG object and continues to initialize EC device
on some broken BIOS.
For example: the ACPI object in EC _REG method can't be found and status error
code is AE_NOT_FOUND.

ACPI Suspend: Enable ACPI during resume if SCI_EN is not set
On some machines, like for example MSI Wind U100, the BIOS doesn't
enable ACPI before returning control to the OS, which sometimes
causes resume to fail. This is against the ACPI specification,
which clearly states that "When the platform is waking from an S1, S2
or S3 state, OSPM assumes the hardware is already in the ACPI mode
and will not issue an ACPI_ENABLE", but it won't hurt to check the
SCI_EN bit and enable ACPI during resume from S3 if this bit is not
set.
Fortunately, we already have acpi_enable() for that, so use it in the
resume code path, before executing _BFS, in analogy with the
resume-from-hibernation code path.
NOTE: We aren't supposed to set SCI_EN directly, because it's owned
by the hardware.

ACPI suspend: Always use the 32-bit waking vector
According to the ACPI specification 2.0c and later, the 64-bit waking vector
should be cleared and the 32-bit waking vector should be used, unless we want
the wake-up code to be called by the BIOS in Protected Mode. Moreover, some
systems (for example HP dv5-1004nr) are known to fail to resume if the 64-bit
waking vector is used. Therefore, modify the code to clear the 64-bit waking
vector, for FACS version 1 or greater, and set the 32-bit one before suspend.

ACPI: Add the support for _TTS object
The _TTS object is defined in the section 7.3 of acpi 3.0b spec.
The _TTS control method is executed by the OSPM at the beginning of
the sleep transition process for S1,S2, S3, S4, and orderly S5 shutdown.
OS will invoke _TTS before it has notified any native mode device drivers
of the sleep state transition. The target sleeping state value is passed to
the _TTS control method.
The _TTS control method is also executed by the OSPM at the end of
any sleep transition process when the system transitions to S0 from
S1, S2, S3, or S4. The _TTS object should be evaluated after it has
notified any native mode device drivers of the end of the sleep state
transition. The working state value (0) is passed to the _TTS control method.
So it is necessary to add the support for _TTS object. The _TTS object
will be evaluated if it exists.
At the same time a block notifier is added to the reboot notifier list so
that the _TTS object will also be evaluated when the system shutdown.
lenb: note that as of Sep 2008, I've not yet seen _TTS in any shipping BIOS.
So this patch is to future-proof Linux, rather than fix the installed base.

cpuidle: use last_state which can reflect the actual state entered
cpuidle accounts the idle time for the C-state it was trying to enter and
not to the actual state that the driver eventually entered. The driver may
select a different state than the one chosen by cpuidle due to
constraints like bus-mastering, etc.
Change the time acounting code to look at the dev->last_state after
returning from target_state->enter(). Driver can modify dev->last_state
internally, inside the enter routine to reflect the actual C-state
entered.

ACPI: Clear WAK_STS on resume
The leading other brand OS appears to clear the WAK_STS flag on resume.
When rebooted, certain BIOSes assume that the system is actually
resuming if it's still set and so fail to reboot correctly. Make sure
that it's cleared at resume time.

>x86: validate against acpi motherboard resources
After the above commit is merged, OS will check whether MCFG area is
reserved in ACPI motherboard resources by calling the function of
acpi_get_devices when there exists MCFG table. In the acpi_get_devices the _STA
object will be evaluated to check the status of the ACPI device. On some broken
BIOS the MYEC object of EC device is initialized as one, which indicates that
EC operation region is already accessible before enabling EC device.So on these
broken BIOS the EC operation region will be accessed in course of evaluating
the _STA object before enabling EC device, which causes that OS will print the
following warning messages:
>ACPI Error (evregion-0315): No handler for Region [EC__] (ffff88007f8145e8)
[EmbeddedControl] [20080609]
>ACPI Error (exfldio-0290): Region EmbeddedControl(3) has no handler [20080321]
>ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG.
EC__.BAT1._STA] (Node ffff81013fc17a00), AE_NOT_EXIST
>ACPI Error (uteval-0233): Method execution failed [\_SB_.PCI0.SBRG.EC__.BAT1.
_STA] (Node ffff81013fc17a00), AE_NOT_EXIST
Although the above warning message is harmless, it looks confusing.
So it is necessary to enable EC device as early as possible.Maybe it is
appropriate to enable it immediately after ACPI full initialization.

PNP: remove old CONFIG_PNP_DEBUG option
CONFIG_PNP_DEBUG is no longer used to turn on dev_dbg() in PNP,
since we have pnp_dbg() which can be enabled at boot-time, so
this patch removes the config option.
Note that pnp_dock_event() checks "#ifdef DEBUG". But there's
never been a clear path for enabling that via configgery. It
happened that CONFIG_PNP_DEBUG enabled it after 1bd17e63a068db6,
but that was accidental and only in 2.6.26.

fujitsu-laptop: better handling of P8010 hotkey
This patch (mostly from Peter Gruber) improves the handling of the hotkeys
for P8010 laptops by passing more accurate input events back to userspace.
This is needed because the P8010 labels these buttons quite differently to
earlier laptops. As part of this, a P8010-specific DMI callback check has

ACPI: fix FADT parsing
The (1.0 inherited) separate length fields in the FADT are byte granular.
Further, PM1a/b may have distinct lengths (if using the v2 fields was
okay) and may live in distinct address spaces. acpi_tb_convert_fadt()
should account for all of these conditions.
Apart from these changes I'm puzzled by the fact that, not just for
acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an
explicit size passed rather than using the size found in the passed GAS.
What happens on a platform that defines PM1{a,b} wider than 16 bits? Of
course, acpi_hw_low_level_{read,write}() at present are entirely
un-prepared to deal with sizes other than 8, 16, or 32, not to speak of a
non-zero bit_offset or access_width...

acer-wmi: Add rfkill support for wireless and bluetooth
This patch implements rfkill support for the wireless and bluetooth devices
commonly found on Acer laptops.
For now, we will always poll these devices once a second to guarantee we
can catch state changes. On newer Acer laptops, it may be possible to rely
on WMI events to do this instead, and experimental support for this will be
added in a later patch.
3G has been deliberately left off for now, as we still have no way to
detect it, (nor, AFAIK, has any Linux user tried the code) and on laptops
that don't support 3G, trying to poll for the status will leave the logs
full of ACPI tracebacks.
The old sysfs interface for wireless and bluetooth will be removed in a
later patch.

this patch).

panasonic-laptop: add Panasonic Let's Note laptop extras driver v0.94
This is a driver for ACPI extras such as hotkeys and backlight
brightness control on various Panasonic "Let's Note" series laptop
computers.
It exports the backlight via the backlight class device API,
and the hotkeys as input event device. Some more esoteric
items like number of installed batteries are exported via sysfs
device attributes.
Hotkey events also generate old-style ACPI enents through
/proc/acpi/event to interoperate with current versions of acpid.

ACPI: fix hotplug race
The hotplug notification handler and drivers' notification handler all
run in one workqueue. Before hotplug removes an acpi device, the
device driver's notification handler is already be recorded to run just
after global notification handler. After hotplug notification handler
runs, acpica will notice a NULL notification handler and crash.
So now we run run hotplug in another workqueue and wait
for all acpi notication handlers finish.
This was found in battery hotplug, but actually all
hotplug can be affected.

Introduce FW_BUG, FW_WARN and FW_INFO to consistenly tell users about BIOS bugs
The idea is to add this to printk after the severity:
printk(KERN_ERR FW_BUG "This is not our fault, BIOS developer: fix it by
simply add ...\n");
If a Firmware issue should be hidden, because it is
work-arounded, but you still want to see something popping up e.g.
for info only:
printk(KERN_INFO FW_INFO "This is done stupid, we can handle it,
but it should better be avoided in future\n");
or on the Linuxfirmwarekit to tell vendors that they did something
stupid or wrong without bothering the user:
printk(KERN_INFO FW_BUG "This is done stupid, we can handle it,
but it should better be avoided in future\n");
Some use cases:
- If a user sees a [Firmware Bug] message in the kernel
he should first update the BIOS before wasting time with
debugging and submiting on old firmware code to mailing
lists.
- The linuxfirmwarekit (http://www.linuxfirmwarekit.org)
tries to detect firmware bugs. It currently is doing that
in userspace which results in:
- Huge test scripts that could be a one liner in the kernel
- A lot of BIOS bugs are already absorbed by the kernel
What do we need such a stupid linuxfirmwarekit for?
- Vendors: Can test their BIOSes for Linux compatibility.
There will be the time when vendors realize that the test utils
on Linux are more strict and using them increases the qualitity
and stability of their products.
- Vendors: Can easily fix up their BIOSes and be more Linux
compatible by:
dmesg |grep "Firmware Bug"
and send the result to their BIOS developer colleagues who should
know what the messages are about and how to fix them, without
the need of studying kernel code.
- Distributions: can do a first automated HW/BIOS checks.
This can then be done without the need of asking kernel developers
who need to dig down the code and explain the details.
Certification can/will just be rejected until
dmesg |grep "Firmware Bug" is empty.
- Thus this can be used as an instrument to enforce cleaner BIOS
code. Currently every stupid Windows ACPI bug is
re-implemented in Linux which is a rather unfortunate situation.
We already have the power to avoid this in e.g. memory
or cpu hot-plug ACPI implementations, because Linux certification
is a must for most vendors in the server area.
Working towards being able to do that in the laptop area
(vendors are starting to look at Linux here also and will use this tool)
is the goal. At least provide them a tool to make it as easy
for this guys (e.g. not needing to browse kernel code) as possible.
- The ordinary Linux user: can go into the next shop, boots the
firmwarekit on his most preferred machines. He chooses one without
BIOS bugs. Unsupported HW is ok, he likes to try out latest projects
which might support them or likes to dig on it on his own, but he
hates to workaround broken BIOSes like hell.
I double checked with the firmwarekit.
There they have:
So the mapping generally is (also depending on how likely the BIOS is
to blame, this could sometimes be difficult):
FW_INFO = INFO
FW_WARN = WARN
FW_BUG = FAIL
For more info about the linuxfirmwarekit and why this is needed
can be found here:
http://www.linuxfirmwarekit.org
While severity matches with the firmwarekit, it might be tricky
to hide messages from the user.
E.g. we recently found out that on HP BIOSes negative temperatures
are returned, which seem to indicate that the thermal zone is
invalid.
We can work around that gracefully by ignoring the thermal zone
and we do not want to bother the ordinary user with a frightening
message: Firmware Bug: thermal management absolutely broken
but want to hide it from the user.
But in the linuxfirmwarekit this should be shown as a real
show stopper (the temperatures could really be wrong,
broken thermal management is one of the worst things
that can happen and the BIOS guys of the machine must
implement this properly).
It is intended to do that (hide it from the user with
KERN_INFO msg, but still print it as a BIOS bug) by:
printk(KERN_INFO FW_BUG "Negativ temperature values detected.
Try to workarounded, BIOS must get fixed\n");
Hope that works out..., no idea how to better hide it
as printk is the only way to easily provide this functionality.
