There are a lot userspace approaches to detect the usage of the platform (laptop, workstation, server, ...) and adjust kernel tunables accordingly (io/process scheduler, power management, ...). These approaches need constant maintaining and are ugly to implement (detect PCMCIA controller -> laptop, does not work on recent systems anymore, ...) On ACPI systems there is an easy and reliable way (if implemented in BIOS and most recent platforms have this value set). -> export it to userspace.

The sysfs interface allowing user space to disable/enable GPEs doesn't work correctly, because a GPE disabled this way will be re-enabled shortly by acpi_ev_asynch_enable_gpe() if it was previosuly enabled by acpi_enable_gpe() (in which case the corresponding bit in its enable register's enable_for_run mask is set). To address this issue make the sysfs GPE interface use acpi_enable_gpe() and acpi_disable_gpe() instead of acpi_set_gpe() so that GPE reference counters are modified by it along with the values of GPE enable registers.

We have ported Rafael's major GPE changes (ACPI: Use GPE reference counting to support shared GPEs) into ACPICA code base. But the port and Rafael's original patch have some differences, so we made below patch to make linux GPE code consistent with ACPICA code base. Most changes are about comments and coding styles. Other noticeable changes are based on: Rafael: Reduce code duplication related to GPE lookup https://patchwork.kernel.org/patch/86237/ Rafael: Always use the same lock for GPE locking https://patchwork.kernel.org/patch/90471/ A new field gpe_count in struct acpi_gpe_block_info to record the number of individual GPEs in block.

由 Tejun Heo 提交于
include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

ACPI GPEs may map to multiple devices. The current GPE interface only provides a mechanism for enabling and disabling GPEs, making it difficult to change the state of GPEs at runtime without extensive cooperation between devices. Add an API to allow devices to indicate whether or not they want their device's GPE to be enabled for both runtime and wakeup events. Remove the old GPE type handling entirely, which gets rid of various quirks, like the implicit disabling with GPE type setting. This requires a small amount of rework in order to ensure that non-wake GPEs are enabled by default to preserve existing behaviour. Based on patches from Matthew Garrett <mjg@redhat.com>.

Impact: cleanup Rather than overriding MODULE_PARAM_PREFIX, build via acpi.o so KBUILD_MODNAME is set to "acpi".

Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set, it's "wake_enabled".

Tejun's commit 7b595756 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'.
