ACPICA commit 0e24fb67cde08d7df7671d7d7b183490dc79707e
The MLC (Module Level Code) is an ACPICA terminology describing the AML
code out of any control method, its support is an indication of the
interpreter behavior during the table loading.The original implementation of MLC in ACPICA had several issues:
1. Out of any control method, besides of the object creating opcodes, only
the code blocks wrapped by "If/Else/While" opcodes were supported.
2. The supported MLC code blocks were executed after loading the table
rather than being executed right in place.
============================================================
The demo of this order issue is as follows:
Name (OBJ1, 1)
If (CND1 == 1)
{
Name (OBJ2, 2)
}
Name (OBJ3, 3)
The original MLC support created OBJ2 after OBJ3's creation.
============================================================
Other than these limitations, MLC support in ACPICA looks correct. And
supporting this should be easy/natural for ACPICA, but enabling of this was
blocked by some ACPICA internal and OSPM specific initialization order
issues we've fixed recently. The wrong support started from the following
false bug fixing commit:
Commit: 7f0c826a437157d2b19662977e9cf3b472cf24a6
Subject: ACPICA: Add support for module-level executable AML code
Commit: 9a884ab64a4d092b4c3bf24fd9a30f7fbd4591e7
Subject: ACPICA: Add additional module-level code support
...We can confirm Windows interpreter behavior via reverse engineering means.
It can be proven that not only If/Else/While wrapped code blocks, all
opcodes can be executed at the module level, including operation region
accesses. And it can be proven that the MLC should be executed right in
place, not in such a deferred way executed after loading the table.And the above facts indeed reflect the spec words around ACPI definition
block tables (DSDT/SSDT/...), the entire table and the Scope object is
defined by the AML specification in BNF style as:
AMLCode := def_block_header term_list
def_scope := scope_op pkg_length name_string term_list
The bodies of the scope opening terms (AMLCode/Scope) are all term_list,
thus the table loading should be no difference than the control method
evaluations as the body of the Method is also defined by the AML
specification as term_list:
def_method := method_op pkg_length name_string method_flags term_list
The only difference is: after evaluating control method, created named
objects may be freed due to no reference, while named objects created by
the table loading should only be freed after unloading the table.So this patch follows the spec and the de-facto standard behavior, enables
the new grammar (term_list) for the table loading.By doing so, beyond the fixes to the above issues, we can see additional
differences comparing to the old grammar based table loading:
1. Originally, beyond the scope opening terms (AMLCode/Scope),
If/Else/While wrapped code blocks under the scope creating terms
(Device/power_resource/Processor/thermal_zone) are also supported as
deferred MLC, which violates the spec defined grammar where object_list
is enforced. With MLC support improved as non-deferred, the interpreter
parses such scope creating terms as term_list rather object_list like the
scope opening terms.
After probing the Windows behavior and proving that it also parses these
terms as term_list, we submitted an ECR (Engineering Change Request) to
the ASWG (ACPI Specification Working Group) to clarify this. The ECR is
titled as "ASL Grammar Clarification for Executable AML Opcodes" and has
been accepted by the ASWG. The new grammar will appear in ACPI
specification 6.2.
2. Originally, Buffer/Package/operation_region/create_XXXField/bank_field
arguments are evaluated in a deferred way after loading the table. With
MLC support improved, they are also parsed right in place during the
table loading.
This is also Windows compliant and the only difference is the removal
of the debugging messages implemented before acpi_ds_execute_arguments(),
see Link # [1] for the details. A previous commit should have ensured
that acpi_check_address_range() won't regress.Note that enabling this feature may cause regressions due to long term
Linux ACPI support on top of the wrong grammar. So this patch also prepares
a global option to be used to roll back to the old grammar during the
period between a regression is reported and the regression is
root-cause-fixed. Lv Zheng.Link: https://bugzilla.kernel.org/show_bug.cgi?id=112911 # [1]

The CPPC tables contain entries for per CPU feedback counters which
allows us to compute the delivered performance over a given interval
of time.The math for delivered performance per the CPPCv5.0+ spec is:
reference perf * delta(delivered perf ctr)/delta(ref perf ctr)Maintaining deltas of the counters in the kernel is messy, as it
depends on when the reads are triggered. (e.g. via the cpufreq
->get() interface). Also the ->get() interace only returns one
value, so cant return raw values. So instead, leave it to userspace
to keep track of raw values and do its math for CPUs it cares about.delivered and reference perf counters are exposed via the same
sysfs file to avoid the potential "skid", if these values are read
individually from userspace.Signed-off-by: Prashanth Prakash

CPPC defined in section 8.4.7 of ACPI 6.0 specification suggests
"To amortize the cost of PCC transactions, OSPM should read or write
all PCC registers via a single read or write command when possible"
This patch enables opportunistic batching of frequency transition
requests whenever the request happen to overlap in time.Currently the access to pcc is serialized by a spin lock which does
not scale well as we increase the number of cores in the system. This
patch improves the scalability by allowing the differnt CPU cores to
update PCC subspace in parallel and by batching requests which will
reduce the certain types of operation(checking command completion bit,
ringing doorbell) by a significant margin.Profiling shows significant improvement in the overall effeciency
to service freq. transition requests. With this patch we observe close
to 30% of the frequency transition requests being batched with other
requests while running apache bench on a ARM platform with 6
independent domains(or sets of related cpus).Signed-off-by: Prashanth Prakash

ACPICA commit a760a98ec84b1ec782e0bff5f6612af6fb89c10c
Originally compiler specific headers are included by the host-specific
headers. This makes build configuration management very inconvenient. And
many inclusion order issues can be hidden accross different host OSes. It
will then likely that some host builds will be broken just because of
fixing some inclusion order issues for other host builds.This patch splits the compiler-specific header inclusions out of the
host-specific headers so that compiler-specific inclusion order issues will
not get entangled in the host-specific inclusion orders.Note that intel compiler defines __GNUC__, so this patch contains special
handling because acintel.h and acgcc.h should be mutual exclusive.Link: https://github.com/acpica/acpica/commit/a760a98e

ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09
When /Za is specified, headers of some Windows SDKs contain bugs breaking
VC builds, and MSVC9's default SDK is one of such header-buggy library.In order to solve this issue, many VC developers stop using /Za. However
we've been asked to have this fixed without removing /Za.In MSVC9 default SDK, this issue can be fixed by restricting
to be the last standard file included by every source file in the projects.
This patch thus moves inclusion to "acapps.h", so that this
issue can be fixed by ensuring that "acapps.h" is always the last standard
file included by all of the ACPICA source files. This is in fact also a
useful cleanup because applications can only include one header (e.x.,
acpidump.h) instead of including acapps.h separately. Lv Zheng.Except some harmless header inclusion re-ordering, Linux kernel is not

ACPICA commit 4aab18466b56f3660f27cffd3c0160900737f844
When mini C library is used, we should have the following macros undefined.
The only user should be the EFI applications:
ACPI_USE_SYSTEM_CLIBRARY=n
ACPI_USE_STANDARD_HEADERS=n
All other applications uses the compiler specific library:
ACPI_USE_SYSTEM_CLIBRARY=y

Linux/BSD kernels are the kind of hosts providing C library but does not
provide the standard headers:
ACPI_USE_SYSTEM_CLIBRARY=y
ACPI_USE_STANDARD_HEADERS=n
But the above logic hasn't been synchronized between the header files.This patch synchronizes all header files to correct C library usages for
different platforms. This patch moves all ACPI_USE_SYSTEM_CLIRARY and
ACPI_USE_STANDARD_HEADERS to the top most lines of a platform specific
header.After synchronization, ACPI_USE_SYSTEM_CLIRARY definition can be removed

ACPICA commit 23a417ca406a527e7ae1710893e59a8b6db30e14
There is a facility in Linux, developers can control the enabling/disabling
of a GPE via /sys/firmware/acpi/interrupts/gpexx. This is mainly for
debugging purposes.But many users expect to use this facility to implement quirks to mask a
specific GPE when there is a gap in Linux causing this GPE to flood. This
is not working correctly because currently this facility invokes
enabling/disabling counting based GPE driver APIs:
acpi_enable_gpe()/acpi_disable_gpe()
and the GPE drivers can still affect the count to mess up the GPE
masking purposes.However, most of the IRQ chip designs allow masking/unmasking IRQs via a
masking bit which is different from the enabled bit to achieve the same
purpose. But the GPE hardware doesn't contain such a feature, this brings
the trouble.In this patch, we introduce a software mechanism to implement the GPE
masking feature, and acpi_mask_gpe() are provided to the OSPMs to
mask/unmask GPEs in the above mentioned situation instead of
acpi_enable_gpe()/acpi_disable_gpe(). ACPICA BZ 1102. Lv Zheng.Link: https://github.com/acpica/acpica/commit/23a417ca

compress-offload API. Below are highlights:- Add the error propagating support in compress-offload API
- HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
default mixer setup change ot turn off the loopback- Lots of updates for ASoC Intel drivers, mostly board support and
bug fixing, and to the NAU8825 driver- Work on generalizing bits of simple-card to allow more code sharing
with the Renesas rsrc-card (which can't use simple-card due to DPCM)- Removal of the Odroid X2 driver due to replacement with simple-card
- Support for several new Mediatek platforms and associated boards
- New ASoC drivers for Allwinner A10, Analog Devices ADAU7002,
Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960
and MAX98504, Realtek RT5514 and Wolfson WM8758"* tag 'sound-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (278 commits)
