ACPI: TAD: Install SystemCMOS address space handler for ACPI000E

2023-08-17T18:01:24Z

Currently, the SystemCMOS address space handler is installed for the ACPI RTC devices (PNP0B00/PNP0B01/PNP0B02) only. But there are platforms with SystemCMOS Operetion Region defined under the ACPI Time and Alarm Device (ACPI000E), which is used by the ACPI pre-defined control methods like _GRT (Get the Real time) and _SRT (Set the Real time). When accessing these control methods via the acpi_tad sysfs interface, missing SystemCMOS address space handler causes errors like below [ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130) [ 478.255458] ACPI Error: Region SystemCMOS (ID=5) has no handler (20230331/exfldio-261) [ 478.255461] Initialized Local Variables for Method [_GRT]: [ 478.255461] Local1: 00000000f182542c Integer 0000000000000000 [ 478.255464] No Arguments are initialized for method [_GRT] [ 478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous error (AE_NOT_EXIST) (20230331/psparse-529) Export two APIs for SystemCMOS address space handler from acpi_cmos_rtc scan handler and install the handler for the ACPI Time and Alarm Device from the ACPI TAD driver.

ACPI: Remove assorted unused declarations of functions

2023-08-17T17:51:44Z

acpi_create_dir()/acpi_remove_dir() are never implemented since the beginning of git history. Commit f8d31489629c ("ACPICA: Debugger: Convert some mechanisms to OSPM specific") declared but never implemented acpi_run_debugger(). Commit 781d737c7466 ("ACPI: Drop power resources driver") removed acpi_power_init() but not its declaration. Signed-off-by: Yue Haibing [ rjw: Subject edits ] Signed-off-by: Rafael J. Wysocki

ACPI: bus: Introduce wrappers for ACPICA notify handler install/remove

2023-07-14T16:58:34Z

Introduce new functions acpi_dev_install_notify_handler() and acpi_dev_remove_notify_handler(), to install and remove, respectively, a handler for AML Notify() operations targeted at a given ACPI device object. They will allow drivers to install Notify() handlers directly instead of providing an ACPI driver .notify() callback to be invoked in the context of a Notify() handler installed by the ACPI bus type code. In particular, this will help platform drivers to provide Notify() handlers for the ACPI companions of the platform devices they bind to. These functions are replacements for acpi_device_install_notify_handler() and acpi_device_remove_notify_handler(), respectively, and after all drivers switch over to using them, the old ones will be dropped.

ACPI: processor: Introduce acpi_processor_osc()

2023-07-14T15:59:40Z

The processor _OSC method is already used for a workaround introduced in commit a21211672c9a ("ACPI / processor: Request native thermal interrupt handling via _OSC"), but in accordance with ACPI 6.5 (and earlier), it should be used for negotiating all of the processor capabilities instead of _PDC (which has been deprecated since ACPI 3.0 and got removed from ACPI 6.5 entirely). Create a new callback function called acpi_processor_osc() to be invoked for every processor object and processor device in the ACPI namespace, in analogy with the already existing acpi_hwp_native_thermal_lvt_osc(). Make this function implement the workaround mentioned above and convey all of the OSPM processor support information to the platform firmware by setting all of the appropriate processor capabilities bits before evaluating _OSC for the given processor. For this purpose, make it call arch_acpi_set_proc_cap_bits() and modify the latter to set ACPI_PROC_CAP_COLLAB_PROC_PERF along with the other processor capabilities bits. Suggested-by: Rafael J.

ACPI: processor: Rename ACPI_PDC symbols

2023-07-14T15:59:40Z

The prefix in the names of the ACPI_PDC symbols suggests that they are only relevant for _PDC, but in fact they can also be used in the _OSC. Change that prefix to a more generic ACPI_PROC_CAP that will better reflect the purpose of those symbols as they represent bits in a general processor capabilities buffer. Rename pdc_intel.h to proc_cap_intel.h to follow the change of the symbol name prefix. No intentional functional impact. Suggested-by: Rafael J.
