[PATCH 00/27] ACPICA: 20140424 Release

From: Lv Zheng
Date: Tue Apr 29 2014 - 22:10:25 EST

ACPICA 20140424 Release Notes for kernel-resident subsystem:

Implemented support to skip/ignore NULL address entries in the RSDT/XSDT.
Some of these tables are known to contain a trailing NULL entry. Lv Zheng.

Removed an extraneous error message for the case where there are a large
number of system GPEs (> 124). This was the "32-bit FADT register is too
long to convert to GAS struct" message, which is irrelevant for GPEs since
the GPEx_BLK_LEN fields of the FADT are always used instead of the (limited
capacity) GAS bit length. Also, several changes to ensure proper support
for GPE numbers > 255, where some "GPE number" fields were 8-bits
internally.

Implemented and deployed additional configuration support for the public
ACPICA external interfaces. Entire classes of interfaces can now be easily
modified or configured out, replaced by stubbed inline functions by
default. Lv Zheng.

Moved all public ACPICA runtime configuration globals to the public ACPICA
external interface file for convenience. Also, removed some obsolete/unused
globals. See the file acpixf.h. Lv Zheng.

Documentation: Added a new section to the ACPICA reference describing the
maximum number of GPEs that can be supported by the FADT-defined GPEs in
block zero and one. About 1200 total. See section 4.4.1 of the ACPICA
reference.

Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The
debug version of the code includes the debug output trace mechanism and has
a much larger code and data size.

Current Release:
Non-Debug Version: 96.8K Code, 27.2K Data, 124.0K Total
Debug Version: 189.5K Code, 79.7K Data, 269.2K Total
Previous Release:
Non-Debug Version: 97.0K Code, 27.2K Data, 124.2K Total
Debug Version: 189.7K Code, 79.5K Data, 269.2K Total

===============

The 20140424 ACPICA kernel-resident subsystem updates are linuxized based
on the pm/linux-next branch to form this patchset.

The patchset has passed the following build/boot tests.
Build tests are performed as follows:
1. i386 + default + COFNIG_ACPI=y
2. i386 + allyes + CONFIG_ACPI=y
3. i386 + default + COFNIG_ACPI=n
4. i386 + allyes + CONFIG_ACPI=n
5. x86_64 + default + COFNIG_ACPI=y
6. x86_64 + allyes + CONFIG_ACPI=y
7. x86_64 + default + COFNIG_ACPI=n
8. x86_64 + allyes + CONFIG_ACPI=n
Boot tests are performed as follows:
1. i386 + default + COFNIG_ACPI=y
2. x86_64 + default + COFNIG_ACPI=y
Where:
1. i386: machine named as "Dell Inspiron Mini 1010"
2. x86_64: machine named as "HP Compaq 8200 Elite SFF PC"
3. default: kernel configuration with following items enabled:
All hardware drivers related to the machines of i386/x86_64
All drivers/acpi configurations
All platform drivers
All ACPI drivers
4 DRM drivers that implement ACPI opregion
All buses with ACPI bindings
All cpufreq configurations
All xen configurations
All ACPI table drivers
4. allyes: kernel configuration generated by allyesconfig.

After applying this series, the divergence result is:
952 Lines, 33.5 Kbytes.
