ACPICA: Fix wrong resource descriptor length for 64-bit build

The "minimal" descriptors such as EndTag are calculated as 12
bytes long, but the actual length in the internal descriptor is
16 because of the round-up to 8 on 64-bit build.

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.

   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 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

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

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.

11 years agoACPI suspend: Always use the 32-bit waking vector
Rafael J. Wysocki [Sat, 6 Sep 2008 11:13:01 +0000]
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.

11 years agoACPI: Add the support for _TTS object
Zhao Yakui [Tue, 12 Aug 2008 02:20:22 +0000]
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.

11 years agocpuidle: use last_state which can reflect the actual state entered
Venkatesh Pallipadi [Mon, 29 Sep 2008 22:24:27 +0000]
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.

11 years agoACPI: Enable EC device immediately after ACPI full initialization
Zhao Yakui [Mon, 6 Oct 2008 02:31:36 +0000]
ACPI: Enable EC device immediately after ACPI full initialization

when there is no ECDT table and no _INI object for EC device, it will be
enabled before scanning ACPI device. But it is too late after the following
the commit is merged.
    >commit 7752d5cfe3d11ca0bb9c673ec38bd78ba6578f8e
    > Author: Robert Hancock <hancockr@shaw.ca>
    > Date:   Fri Feb 15 01:27:20 2008 -0800
       >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.
