ACPICA: OSL: Add portable file IO to improve portability

2014-07-08T12:22:25+00:00

This patch adds portable file IO to generic OSL to improve the portability
of the applications.

A portable application may use different file IO interfaces than the
standard C library ones. This patch thus introduces an abstract file IO
layer into the generic OSL.

Note that this patch does not introduce users of such interfaces, further
patches should introduce users one by one carefully with build tests
performed. Lv Zheng.

ACPICA: Revert "Headers: Deploy #pragma pack (push) and (pop)."

2014-03-18T00:53:45+00:00

This reverts commit aae576e5faefa8ba70647efa320d4747b6375f1e.
Push and Pop are not portable "enough", and caused problems for
some ACPICA customers.

ACPICA: Headers: Deploy #pragma pack (push) and (pop).

2014-02-26T23:45:59+00:00

Use push and pop to both guarantee that the correct alignment is used,
and to restore the alignment to whatever it was before the header
was included.

It is reported that the #pragma pack(push/pop) directives are not supported
by the specific GCCs, but this patch still doesn't affect kernel build
as there are already #pragma pack([1]) directives used in the old ACPICA
headers, which means there shouldn't be GCCs that are currently used to
compile the ACPI kernels do not support #pragma pack() directives.

ACPICA: Update aclinux.h for new OSL override mechanism.

2013-10-31T13:36:41+00:00

The new ACPICA OSL override mechanism is used to solve these issues
for the Linux OSL:
 1. Linux can implement OSL using a macro.
 2. Linux can implement OSL using an inlined function.
 3. Linux can leave OSL not implemented for __KERNEL__ undefined code
    fragments.
 4. Linux can add sparse declarators (__iomem) to OSL.
 5. Linux can add memory tuning declarators (__init/__exit) to OSL.
This patch also moves Linux specific OSL to aclinux.h which has not been
maintained in the ACPICA code base.  Lv Zheng.

Known issue:

 From ACPICA's perspective, actypes.h should be included after inclusion
 of acenv.h.  But currently in Linux, aclinux.h included by acenv.h has
 included actypes.h to find ACPICA types for inline functions.  This is a
 known and existing issue and currently there is no real problem caused
 by this issue for Linux kernel build.  Thus this issue is not covered by
 this cleanup commit.

ACPICA: Add support to allow host OS to redefine individual OSL prototypes.

2013-10-31T13:35:50+00:00

This change enables the host OS to redefine OSL prototypes found in the
acpiosxf.h file. This allows the host OS to implement OSL interfaces with
a macro or inlined function. Further, it allows the host OS to add any
additional required modifiers such as __iomem, __init, __exit, etc.,
as necessary on a per-interface basis. Enables maximum flexibility
for the OSL interfaces. Lv Zheng.

ACPICA: Cleanup memory allocation macros and configurability.

2013-10-30T11:24:21+00:00

In the common case, the ACPI_ALLOCATE and related macros now resolve
directly to their respective acpi_os* OSL interfaces. Two options:
1) The ACPI_ALLOCATE_ZEROED macro defaults to a simple local implementation
   by default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define.
2) For ACPI execution simulation environment (AcpiExec) which is not
   shipped with the Linux kernel, the macros can optionally be resolved to
   the local interfaces that track each allocation (used to immediately
   detect memory leaks).

after that.
