f8fb4c383e ACPICA: Debugger: Split debugger initialization/termination APIs
ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432

It is likely that the debugger is enabled only when a userspace program
explicitly tells a kernel to do so, so it shouldn't be initialized as
early as current implementation.

The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to call
the new APIs by itself. And BSD developers may also get notified to invoke
the APIs for DDB enabling. Lv Zheng.

This patch doesn't affect Linux kernel as debugger is currently not enabled
in the Linux kernel.

5f05586c60 ACPI: Decouple ACPI idle and ACPI processor drivers
This patch introduces a new Kconfig symbol, ACPI_PROCESSOR_IDLE,
which is auto selected by architectures which support the ACPI
based C states for CPU Idle management.

The processor_idle driver in its present form contains declarations
specific to X86 and IA64. Since there are no reasonable defaults
for other architectures e.g. ARM64, the driver is selected only for
X86 or IA64.

This helps in decoupling the ACPI processor_driver from the ACPI
processor_idle driver which is useful for the upcoming alternative
patchwork for controlling CPU Performance (CPPC) and CPU Idle (LPI).

239708a3af ACPI: Split out ACPI PSS from ACPI Processor driver
The ACPI processor driver is currently tied too closely
to the ACPI P-states (PSS) and other related constructs
for controlling CPU performance.

The newer ACPI specification (v5.1 onwards) introduces
alternative methods to PSS. These new mechanisms are
described within each ACPI Processor object and so they
need to be scanned whenever a new Processor object is detected.
This patch introduces a new Kconfig symbol to allow for
finer configurability among the two options for controlling
performance states. There is no change in functionality and
the option is auto-selected by the architectures which support it.

A future commit will introduce support for CPPC: A newer method of
controlling CPU performance. The OS is not expected to support
CPPC and PSS at the same time, so the Kconfig option lets us make
the two mutually exclusive at compile time.

ACPICA commit 49c6a6517a906900e9baa51ad5859beeb8a3089f

The following error logs can be seen for calloc/free/malloc/realloc that
defined in the stdlib.h:

ab6c573320 ACPICA: Executer: Add interpreter tracing mode for method tracing facility
ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b

The acpi_debug_trace() is the mechanism known as ACPI method tracing that is
used by Linux as ACPICA debugging message reducer. This facility can be
controlled through Linux ACPI subsystem - /sys/module/acpi/parameters.
This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace
logs in the kernel dmesg output.

This patch enhances acpi_debug_trace() to make it not only a message reducer,
but a real tracer to trace AML interpreter execution. Note that in addition
to the AML tracer enabling, this patch also updates the facility with the
following enhancements:
1. Allow a full path to be specified by the acpi_debug_trace() API.
2. Allow any method rather than just the entrance of acpi_evaluate_object()
   to be traced.
3. All interpreter ACPI_LV_TRACE_POINT messages are collected for
   ACPI_EXECUTER layer.

The Makefile of drivers/acpi/acpica is also updated to include exdebug.o
and the duplicated stubs are removed after that.

Note that since this patch has enhanced the method tracing facility, Linux
need also be updated after applying this patch. Lv Zheng.

a616dc2fe5 ACPICA: Dispatcher: Add trace support for interpreter
ACPICA commit 71299ec8b49054daace0df50268e8e055654ca37

This patch adds trace point at the following point:
 1. Begin/end of a control method execution;
 2. Begin/end of an opcode execution.

The trace point feature can be enabled by defining ACPI_DEBUG_OUTPUT
and specifying a debug level that includes ACPI_LV_TRACDE_POINT and the
debug layers that include ACPI_PARSER and ACPI_DISPACTCHER.

In order to make aml_op_name of union acpi_parse_object usable for tracer, it is
enabled for ACPI_DEBUG_OUTPUT in this patch. Lv Zheng.

d1e7ffe50b ACPICA: Namespace: Add function to directly return normalized full path
ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea

This patch adds functions to return normalized full path instead of
"external path". The external path contains trailing "_" for each
name segment while the normalized full path doesn't contain the
trailing "_".

Currently this function is used by the method tracing users to specify a
none trailing "_" attached name path. Lv Zheng.

Note that we need to validate and switch all Linux kernel acpi_get_name()
users to use the new name type before removing the old name type from
ACPICA.

Pull ACPICA updates from Rafael Wysocki:
 "Additional ACPICA material for v4.2-rc1

  This will update the ACPICA code in the kernel to upstream revision
  20150619 (a bug-fix release mostly including stable-candidate fixes)
  and restore an earlier ACPICA commit that had to be reverted due to a
  regression introduced by it (the regression is addressed by
  blacklisting the only known system affected by it to date).

  The only new feature added by this update is the support for
  overriding objects in the ACPI namespace and a new ACPI table that can
  be used for that called the Override System Definition Table (OSDT).
  That should allow us to "patch" the ACPI namespace built from
  incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
  during system startup without the need to provide replacements for all
  of those tables in the future.

  Specifics:

   - Fix system resume problems related to 32-bit and 64-bit versions of
     the Firmware ACPI Control Structure (FACS) in the firmare (Lv
     Zheng)

   - Fix double initialization of the FACS (Lv Zheng)

   - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)

   - Add support for the (currently missing) new GIC version field in
     the Multiple APIC Description Table (MADT) (Hanjun Guo)

   - Add support for overriding objects in the ACPI namespace to ACPICA
     and OSDT support (Lv Zheng, Bob Moore, Zhang Rui)

   - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore)

   - Restore the commit modifying _REV to always return "2" (as required
     by ACPI 6) and add a blacklisting mechanism for systems that may be
     affected by that change (Rafael J Wysocki)

9005694e40 ACPICA: Update definitions for the TCPA and TPM2 ACPI tables
ACPICA commit 33140b4498666337dd33a00cf3c4797a53981a7b

Changes for a new version of the 3rd party spec for these tables,
the "TCG ACPI Specification", December 14, 2014. Also, moved the
definition of TPM2 to actbl2.h, next to TCPA, since both should
be together.

Update the table compiler/disassembler code for the tables.
However, the "Server" TCPA table is not supported at this time.

ACPICA commit c0ce529e1fbb8ec47d2522a3aa10f3ab77e16e41

There is no reference counting implemented for struct acpi_namespace_node, so it
is currently not removable during runtime.
This patch changes the namespace override code to keep the old
struct acpi_namespace_node undeleted so that the override mechanism can happen
during runtime. Bob Moore.

07cf6ce595 ACPICA: EFI: Add EFI interface definitions to eliminate dependency of GNU EFI
ACPICA commit 5d00e67a74542d030f0a55e7a947a020ef0d9693

This patch copies EFI interface definitions to the ACPICA code base so that
the EFI utility support can be ported to other EFI implementation.

Known issues:
1. MS Builds of uefi_call_wrapper()
   The uefi_call_wrapper() in GNU EFI is implemented in a the way to work
   around the ABI difference between Unix and MS. While I don't have
   environment to test the MS builds.

In order to port the ACPICA utilities to other EFI implementation, all that
need to be done is to impelement the 64-bit division support and the
program entry point where the efi_main() is invoked. Code to impelement
these is platform specific, and ACPICA currently choose to hide such
platform specific code within the specific EFI impelementation. Lv Zheng.

c04e1fb439 ACPICA: Tables: Enable both 32-bit and 64-bit FACS
ACPICA commit f7b86f35416e3d1f71c3d816ff5075ddd33ed486

The following commit is reported to have broken s2ram on some platforms:
 Commit: 0249ed2444
 ACPICA: Add option to favor 32-bit FADT addresses.
The platform reports 2 FACS tables (which is not allowed by ACPI
specification) and the new 32-bit address favor rule forces OSPMs to use
the FACS table reported via FADT's X_FIRMWARE_CTRL field.

The root cause of the reported bug might be one of the followings:
1. BIOS may favor the 64-bit firmware waking vector address when the
   version of the FACS is greater than 0 and Linux currently only supports
   resuming from the real mode, so the 64-bit firmware waking vector has
   never been set and might be invalid to BIOS while the commit enables
   higher version FACS.
2. BIOS may favor the FACS reported via the "FIRMWARE_CTRL" field in the
   FADT while the commit doesn't set the firmware waking vector address of
   the FACS reported by "FIRMWARE_CTRL", it only sets the firware waking
   vector address of the FACS reported by "X_FIRMWARE_CTRL".

This patch excludes the cases that can trigger the bugs caused by the root
cause 2.

There is no handshaking mechanism can be used by OSPM to tell BIOS which
FACS is currently used. Thus the FACS reported by "FIRMWARE_CTRL" may still
be used by BIOS and the 0 value of the 32-bit firmware waking vector might
trigger such failure.

This patch tries to favor 32bit FACS address in another way where both the
FACS reported by "FIRMWARE_CTRL" and the FACS reported by "X_FIRMWARE_CTRL"
are loaded so that further commit can set firmware waking vector in the
both tables to ensure we can exclude the cases that trigger the bugs caused
by the root cause 2. The exclusion is split into 2 commits as this commit
is also useful for dumping more ACPI tables, it won't get reverted when
such exclusion is no longer necessary. Lv Zheng.

aca2a5d3a8 ACPICA: Hardware: Enable 64-bit firmware waking vector for selected FACS
ACPICA commit 7aa598d711644ab0de5f70ad88f1e2de253115e4

The following commit is reported to have broken s2ram on some platforms:
 Commit: 0249ed2444
 ACPICA: Add option to favor 32-bit FADT addresses.
The platform reports 2 FACS tables (which is not allowed by ACPI
specification) and the new 32-bit address favor rule forces OSPMs to use
the FACS table reported via FADT's X_FIRMWARE_CTRL field.

The root cause of the reported bug might be one of the followings:
1. BIOS may favor the 64-bit firmware waking vector address when the
   version of the FACS is greater than 0 and Linux currently only supports
   resuming from the real mode, so the 64-bit firmware waking vector has
   never been set and might be invalid to BIOS while the commit enables
   higher version FACS.
2. BIOS may favor the FACS reported via the "FIRMWARE_CTRL" field in the
   FADT while the commit doesn't set the firmware waking vector address of
   the FACS reported by "FIRMWARE_CTRL", it only sets the firware waking
   vector address of the FACS reported by "X_FIRMWARE_CTRL".

This patch excludes the cases that can trigger the bugs caused by the root
cause 1.

ACPI specification says:
A. 32-bit FACS address (FIRMWARE_CTRL field in FADT):
   Physical memory address of the FACS, where OSPM and firmware exchange
   control information.
   If the X_FIRMWARE_CTRL field contains a non zero value then this field
   must be zero.
   A zero value indicates that no FACS is specified by this field.
B. 64-bit FACS address (X_FIRMWARE_CTRL field in FADT):
   64bit physical memory address of the FACS.
   This field is used when the physical address of the FACS is above 4GB.
   If the FIRMWARE_CTRL field contains a non zero value then this field
   must be zero.
   A zero value indicates that no FACS is specified by this field.
Thus the 32bit and 64bit firmware waking vector should indicate completely
different resuming environment - real mode (1MB addressable) and non real
mode (4GB+ addressable) and currently Linux only supports resuming from
real mode.

This patch enables 64-bit firmware waking vector for selected FACS via new
acpi_set_firmware_waking_vectors() API so that it's up to OSPMs to
determine which resuming mode should be used by BIOS and ACPICA changes
won't trigger the bugs caused by the root cause 1. Lv Zheng.

but there were already ~63 of_node local variables or function parameters
(no single acpi_node though, but anyway).

After debugging undefined but used of_node local varible (which turned out
to reference static function of_node() instead) it became clear that the names
for the functions are too short and too generic for global scope.

87521e16a7 acpi-video-detect: Rewrite backlight interface selection logic
Currently we have 2 kernel commandline options + dmi-quirks in 3 places all
interacting (in interesting ways) to select which which backlight interface
to use. On the commandline we've acpi_backlight=[video|vendor] and
video.use_native_backlight=[0|1]. DMI quirks we have in
acpi/video-detect.c, acpi/video.c and drivers/platform/x86/*.c .

This commit is the first step to cleaning this up, replacing the 2 cmdline
options with just acpi_backlight=[video|vendor|native|none], and adds a
new API to video_detect.c to reflect this.

Follow up commits will also move other related code, like unregistering the
acpi_video backlight interface if it was registered before other drivers
which take priority over it are loaded, to video_detect.c where this
logic really belongs.

d056267483 ACPI / scan: Parse _CCA and setup device coherency
This patch implements support for ACPI _CCA object, which is introduced in
ACPIv5.1, can be used for specifying device DMA coherency attribute.

The parsing logic traverses device namespace to parse coherency
information, and stores it in acpi_device_flags. Then uses it to call
arch_setup_dma_ops() when creating each device enumerated in DSDT
during ACPI scan.

This patch also introduces acpi_dma_is_coherent(), which provides
an interface for device drivers to check the coherency information
similarly to the of_dma_is_coherent().
