x86/acpi: Add support for CPU offlining for ACPI MADT wakeup method

2024-06-17T15:46:25+00:00

MADT Multiprocessor Wakeup structure version 1 brings support for CPU offlining: BIOS provides a reset vector where the CPU has to jump to for offlining itself. The new TEST mailbox command can be used to test whether the CPU offlined itself which means the BIOS has control over the CPU and can online it again via the ACPI MADT wakeup method. Add CPU offlining support for the ACPI MADT wakeup method by implementing custom cpu_die(), play_dead() and stop_this_cpu() SMP operations. CPU offlining makes it possible to hand over secondary CPUs over kexec, not limiting the second kernel to a single CPU. The change conforms to the approved ACPI spec change proposal. See the Link.

x86/acpi: Rename fields in the acpi_madt_multiproc_wakeup structure

2024-06-17T15:46:15+00:00

In order to support MADT wakeup structure version 1, provide more appropriate names for the fields in the structure. Rename 'mailbox_version' to 'version'. This field signifies the version of the structure and the related protocols, rather than the version of the mailbox. This field has not been utilized in the code thus far. Rename 'base_address' to 'mailbox_address' to clarify the kind of address it represents. In version 1, the structure includes the reset vector address. Clear and distinct naming helps to prevent any confusion. Signed-off-by: Kirill A.

Merge branches 'acpi-scan' and 'acpi-tables'

Merge ACPI device enumeration changes and ACPI data-only tables support updates for 6.10: - Rearrange fields in several structures to effectively eliminate computations from container_of() in some cases (Andy Shevchenko). - Do some assorted cleanups of the ACPI device enumeration code (Andy Shevchenko). - Make the ACPI device enumeration code skip devices with _STA values clearly identified by the specification as invalid (Rafael Wysocki). - Rework the handling of the NHLT table to simplify and clarify it and drop some obsolete pieces (Cezary Rojewski). * acpi-scan: ACPI: scan: Avoid enumerating devices with clearly invalid _STA values ACPI: scan: Introduce typedef:s for struct acpi_hotplug_context members ACPI: scan: Use standard error checking pattern ACPI: scan: Move misleading comment to acpi_dma_configure_id() ACPI: scan: Use list_first_entry_or_null() in acpi_device_hid() ACPI: bus: Don't use "proxy" headers ACPI: bus: Make container_of() no-op where it makes sense * acpi-tables: ACPI: NHLT: Streamline struct naming ACPI: NHLT: Drop redundant types ACPI: NHLT: Introduce API for the table ACPI: NHLT: Reintroduce types the table consists of

ACPICA: ACPI 6.5: RAS2: Add support for RAS2 table

2024-04-12T13:11:24+00:00

ACPICA commit c581606cf49b7574d29c02b1a3bc144650375e32 Add support for ACPI RAS2 feature table(RAS2) defined in the ACPI 6.5 Specification & upwards revision, section 5.2.21. The RAS2 table provides interfaces for platform RAS features. RAS2 offers the same services as RASF, but is more scalable than the latter. RAS2 supports independent RAS controls and capabilities for a given RAS feature for multiple instances of the same component in a given system. The platform can support either RAS2 or RASF but not both. Link: https://github.com/acpica/acpica/commit/c581606c Signed-off-by: Shiju Jose Signed-off-by: Rafael J. Wysocki

ACPI: NHLT: Reintroduce types the table consists of

2024-03-27T15:36:45+00:00

ACPICA commit 32260f5ce519e854546ce907fc0cc449e1fe51fe Non HDAudio Link Table (NHLT) is designed to separate hardware-related description (registers) from AudioDSP firmware-related one i.e.: pipelines and modules that together make up the audio stream on Intel DSPs. This task is important as same set of hardware registers can be used with different topologies and vice versa, same topology could be utilized with different set of hardware. As the hardware registers description is directly tied to specific platform, intention is to have such description part of low-level firmware e.g.: BIOS. The initial design has been provided in early Sky Lake (SKL) days. The audio architecture goes by the name cAVS. SKL is a representative of cAVS 1.5. The table helps describe endpoint capabilities ever since. While Raptor Lake (RPL) is the last of cAVS architecture - cAVS 2.5 to be precise - its successor, the ACE architecture which begun with Meteor Lake (MTL) inherited the design for all I2S and PDM configurations. These two configurations are the primary targets for NHLT table. Due to naming conflicts with existing code, several structs are named 'nhlt2' rather than 'nhlt'. Follow up changes clean this up once existing code has no users and is removed. Link: https://github.com/acpica/acpica/pull/912 Signed-off-by: Cezary Rojewski Signed-off-by: Rafael J. Wysocki
