ACPICA: ACPI 6.4: PPTT: include all fields in subtable type1

2026-01-15T17:17:48+00:00

In PPTT version 3 an extra field, Cache ID, was added to the Cache Type Structure. The struct, struct acpi_pptt_cache_v1, contains only this field. This differs from the treatment of other versioned structures and is unexpected for linux which reuses the actbl2.h header file. Include all the fields of the new Cache Type Structure in struct acpi_pptt_cache_v1 and fix up all uses.

ACPICA: Add SoundWire File Table (SWFT) signature

2025-08-25T14:44:36+00:00

The File Download (FDL) process of SoundWire Class Audio (SDCA) driver, which provides code/data which may be required by an SDCA device, utilizes SWFT to obtain that code/data. There is a single SWFT for the system, and SWFT can contain multiple files (information about the file as well as its binary contents). The SWFT has a standard ACPI Descriptor Table Header, followed by SoundWire File definitions as described in Discovery and Configuration (DisCo) Specification for SoundWire® Link: https://github.com/acpica/acpica/commit/18c96022 Signed-off-by: Maciej Strozek Reviewed-by: Charles Keepax Link: https://patch.msgid.link/20250811134505.1162661-1-mstrozek@opensource.cirrus.com Signed-off-by: Rafael J.
