ACPI / osi: Collect _OSI handling into one single file

2016-05-04T22:13:53+00:00

_OSI handling code grows giant and it's time to move them into one file. This patch collects all _OSI handling code into one single file. So that we only have the following functions to be used externally: early_acpi_osi_init(): Used by DMI detections; acpi_osi_init(): Used to initialize OSI command line settings and install Linux specific _OSI handler; acpi_osi_setup(): The API that should be used by the external quirks. acpi_osi_is_win8(): The API is used by the external drivers to determine if BIOS supports Win8. CONFIG_DMI is not useful as stub dmi_check_system() can make everything stub because of strip. No functional changes.

ACPI: implement Generic Event Device

2016-04-09T00:09:26+00:00

Generic Event Device described in ACPI 6.1 allows platforms to handle platform interrupts in ACPI ASL statements. It borrows constructs like _EVT from GPIO events. All interrupts are listed in _CRS and the handler is written in _EVT method. Here is an example. Device (GED0) { Name (_HID, "ACPI0013") Name (_UID, 0) Name(_CRS, ResourceTemplate () { Interrupt(ResourceConsumer, Edge, ActiveHigh, Shared, , , ) {123} }) Method (_EVT, 1) { if (Lequal(123, Arg0)) { } } } Wake capability has not been implemented yet.

ACPI / scan: AMBA bus probing support

2016-02-16T18:58:25+00:00

On ARM64 some devices use the AMBA device and not the platform bus for probing so add support for this. Uses a dummy clock for apb_pclk as ACPI does not have a suitable clock representation and to keep the core AMBA bus code unchanged between probing methods.

ACPI / debugger: Add module support for ACPI debugger

2015-12-14T23:17:44+00:00

This patch converts AML debugger into a loadable module. Note that, it implements driver unloading at the level dependent on the module reference count. Which means if ACPI debugger is being used by a userspace program, "rmmod acpi_dbg" should result in failure. Signed-off-by: Lv Zheng Signed-off-by: Rafael J. Wysocki

ACPI / debugger: Add IO interface to access debugger functionalities

2015-12-14T23:17:44+00:00

This patch adds /sys/kernel/debug/acpi/acpidbg, which can be used by userspace programs to access ACPICA debugger functionalities. Known issue: 1. IO flush support acpi_os_notify_command_complete() and acpi_os_wait_command_ready() can be used by acpi_dbg module to implement .flush() filesystem operation. While this patch doesn't go that far. It then becomes userspace tool's duty now to flush old commands before executing new batch mode commands. Signed-off-by: Lv Zheng Signed-off-by: Rafael J. Wysocki

ACPI: Fix build errors due objects compiled unconditionally

2015-12-09T22:40:41+00:00

If the CONFIG_ACPI Kconfig symbol is not enabled and a partial build is attempted, compile errors will happen due missing types and identifiers. This can be easily reproduced with the following commands: $ export CROSS_COMPILE="arm-linux-gnueabihf-" ARCH=arm $ make allmodconfig $ make M=drivers/acpi/ CC drivers/acpi//tables.o drivers/acpi//tables.c:235:3: warning: 'struct acpi_subtable_proc' declared inside parameter list unsigned int max_entries) ^ drivers/acpi//tables.c:235:3: warning: its scope is only this definition or declaration, which is probably not what you want drivers/acpi//tables.c: In function 'acpi_parse_entries_array': drivers/acpi//tables.c:269:4: error: invalid use of undefined type 'struct acpi_subtable_proc' ... scripts/Makefile.build:258: recipe for target 'drivers/acpi//tables.o' failed make[1]: *** [drivers/acpi//tables.o] Error 1 Makefile:1401: recipe for target '_module_drivers/acpi/' failed make: *** [_module_drivers/acpi/] Error 2 This is because objects are tried to be built unconditionally even when CONFIG_ACPI is not enabled. This is usually not a problem since arches' Kconfig sources drivers/acpi/Kconfig directly and also selects ACPI but the Makefile should conditionally build the objects as well to prevent these build errors.

ACPI: Introduce CPU performance controls using CPPC

2015-10-12T20:49:55+00:00

CPPC stands for Collaborative Processor Performance Controls and is defined in the ACPI v5.0+ spec. It describes CPU performance controls on an abstract and continuous scale allowing the platform (e.g. remote power processor) to flexibly optimize CPU performance with its knowledge of power budgets and other architecture specific knowledge. This patch adds a shim which exports commonly used functions to get and set CPPC specific controls for each CPU. This enables CPUFreq drivers to gather per CPU performance data and use with exisiting governors or even allows for customized governors which are implemented inside CPUFreq drivers.
