ACPICA: provide abstraction for raw_spinlock_t

2018-05-10T15:18:45Z

Provide a new lock type acpi_raw_spinlock which is implemented as raw_spinlock_t on Linux. This type should be used in code which covers small areas of code and disables interrupts only for short time even on a realtime OS. There is a fallback to spinlock_t if an OS does not provide an implementation for acpi_raw_spinlock. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Rafael J. Wysocki

ACPICA: Events: Dispatch GPEs after enabling for the first time

2018-03-18T17:52:00Z

After being enabled for the first time, the GPEs may have STS bits already set. Setting EN bits is not sufficient to trigger the GPEs again, so this patch polls GPEs after enabling them for the first time. This is a cleaner version on top of the "GPE clear" fix generated according to Mika's report and Rafael's original Linux based fix. Based on Linux commit originated from Rafael J. Wysocki, fixed by Lv Zheng. Signed-off-by: Lv Zheng Signed-off-by: Erik Schmauss Signed-off-by: Rafael J. Wysocki

ACPICA: Add option to disable Package object name resolution errors

2018-02-21T22:51:08Z

ACPICA commit a6c3c725c44dd44ad9d3f2b2a64351fdbe6e0014 For the kernel-resident ACPICA, optionally be silent about the NOT_FOUND case. Although this is potentially a serious problem, it can generate a lot of noise/errors on platforms whose firmware carries around a bunch of unused Package objects. To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header.

ACPICA: CLib: Add short multiply/shift support

2017-08-03T21:34:16Z

ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5 In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit multiply/shift supports are also required to be implemented. Otherwise, MSVC complains: acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr Note: 1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have different math64 supports. 2. Support of gcc math64 is not included in this patch. 3. Support of EDK2 arch independent math64 is done via linking to base_lib. This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng. For Linux kernel, this patch is a functional no-op.

Back port of "ACPICA: Use designated initializers"

ACPICA commit 47538f5f0773c0820d8f552e20f6e77104290c01 The following commit is not correctly linuxized by its ACPICA form (see link #1 for reference): Commit: 3d867f6c5fd6535cdeceef3170e5e84e5dd80fc1 Subject: ACPICA: Use designated initializers Thus breaks linuxize process. This patch is a linuxized back port result of the upstreamed ACPICA commit (see link #2 for reference).

ACPICA: Use designated initializers

2017-06-27T20:27:24Z

The struct layout randomization plugin detects and randomizes any structs that contain only function pointers. Once layout is randomized, all initialization must be designated or the compiler will misalign the assignments. This switches all the ACPICA function pointer struct to use designated initializers, using the proposed upstream ACPICA macro: https://github.com/acpica/acpica/pull/248/ Signed-off-by: Kees Cook Signed-off-by: Rafael J.

ACPICA: OSL: Add support to exclude stdarg.h

ACPICA commit e2df7455a9a4301b03668e4c9c02c7a564cc841c Some hosts may choose not to include stdarg.h, implementing a configurability in acgcc.h, allowing OSen like Solaris to exclude stdarg.h. This patch also fixes acintel.h accordingly without providing builtin support as Intel compiler is similar as GCC. Reported by Dana Myers, fixed by Lv Zheng.
