Rafael J. Wysocki f317c7dc12 ACPICA: Clear status of all events when entering sleep states
Commit fa85015c0d (ACPICA: Clear status of all events when entering
S5) made the sleep state entry code in ACPICA clear the status of all
ACPI events when entering S5 to fix a functional regression reported
against commit 18996f2db9 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume).  However, it is reported
now that the regression also affects system states other than S5 on
some systems and causes them to wake up from sleep prematurely.

For this reason, make the code in question clear the status of all
ACPI events when entering all sleep states (in addition to S5) to
avoid the premature wakeups (this may cause some wakeup events to
be missed in theory, but the likelihood of that is small and the
change here simply restores the previous behavior of the code).

Rafael J. Wysocki fa85015c0d ACPICA: Clear status of all events when entering S5
After commit 18996f2db9 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume) the status of ACPI events
is not cleared any more when entering the ACPI S5 system state (power
off) which causes some systems to power up immediately after turing
off power in certain situations.

That is a functional regression, so address it by making the code
clear the status of all ACPI events again when entering S5 (for
system-wide suspend or hibernation the clearing of the status of all
events is not desirable, as it might cause the kernel to miss wakeup
events sometimes).

Erik Schmauss 18996f2db9 ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume
Unconditionally clearing ACPI IRQs during suspend/resume can lead to
unexpected IRQ losts. This patch fixes this issue by removing such IRQ
clearing code.

If this patch triggers regression, the regression should be in the GPE
handlers that cannot correctly determine some spurious triggered events as
no-ops. Please report any regression related to this commit to the ACPI
component on kernel bugzilla. Lv Zheng.

ACPICA commit ba665dc8e20d9f7730466a659564dd6c557a6cbc

In Linux, para-virtualization implmentation hooks critical register
writes to prevent real hardware operations. This increases divergences
when the sleep registers are cracked in Linux resident ACPICA.

This patch tries to introduce a single OSL to reduce the divergences.

Len Brown 3f6f49c785 ACPI: delete _GTS/_BFS support
_GTS and _BFS were added to the suspend/resume flow
in the ACPI 2.0 specification.

Linux dutifully implemented _GTS and _BFS.
We discovered that it was rarely seen in systems
in the field.  Further, some of those systems had
AML so bogus that it could never work -- proof that
no other operating system supports _GTS and _BFS.
So we made _GTS and _BFS optional via modparam,
and disabled them by default.

But we've had to complicate some code to keep
this support in the kernel, as these methods are defined
to be evaluated very close to sleep entry and exit.
Indeed, no other AML is ever evaluated with interrupts off.

We have submitted a proposal for _GTS and _BFS
to be officially removed from the ACPI specification
on the next revision.  Here we remove it from Linux.

The bug snuck back in in commit 2feec47d4c (ACPICA: ACPI 5: Support
for new FADT SleepStatus, SleepControl registers, 2012-02-14),
presumably by copy/pasting a copy of the code without that fix for the
legacy case.

On affected machines, after that commit, the machine locks up hard on
resume from suspend.  The same fix as seven years ago still works.

Lin Ming 8a73b17e4c ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFS
Enhanced the sleep/wake interfaces to optionally execute the
_GTS method (Going To Sleep), and the _BFS method (Back From
Sleep).  Windows apparently does not execute these methods, and
therefore these methods are often untested. It has been seen on
some systems where the execution of these methods causes errors
and also prevents the machine from entering S5. It is therefore
suggested that host operating systems do not execute these methods
by default. In the future, perhaps these methods can be optionally
executed based on the age of the system and/or what is the newest
version of Windows that the BIOS asks for via _OSI.

Joseph Cihula 86886e55b2 x86, intel_txt: Intel TXT Sx shutdown support
Support for graceful handling of sleep states (S3/S4/S5) after an Intel(R) TXT launch.

Without this patch, attempting to place the system in one of the ACPI sleep
states (S3/S4/S5) will cause the TXT hardware to treat this as an attack and
will cause a system reset, with memory locked.  Not only may the subsequent
memory scrub take some time, but the platform will be unable to enter the
requested power state.

This patch calls back into the tboot so that it may properly and securely clean
up system state and clear the secrets-in-memory flag, after which it will place
the system into the requested sleep state using ACPI information passed by the kernel.

Bob Moore 32c9ef994d ACPICA: Add function to handle PM1 control registers
Added acpi_hw_write_pm1_control. This function writes both of the PM1
control registers (A/B). These registers are different than than
the PM1 A/B status and enable registers in that different values
can be written to the A/B registers.  Most notably, the SLP_TYP
bits can be different, as per the values returned from the _Sx
predefined methods.
