Subject: [GIT PULL] ACPI support updates for v6.18-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-6.18-rc1
with top-most commit c87072064bd482930a021e88c11f438e780d36de
Merge branches 'acpi-apei', 'acpi-misc' and 'pnp'
on top of commit 07e27ad16399afcd693be20211b0dfae63e0615f
Linux 6.17-rc7
to receive ACPI updates for 6.18-rc1.
These include an ACPICA update (upstream revision 20250807 with a few
fixes on top), fixes and cleanups of the ACPI processor driver, fixes
and cleanups of the ACPI properties management code, one more ACPI IRQ
resource management quirk, one more ACPI backlight quirk, an ACPI
device enumeration quirk related to _DEP, a power resource quirk
related to WWAN modem for HP EliteBook 855 G7, ACPI SPCR table parser
extensions, an ACPI APEI EINJ driver update allowing it to handle
more address types, and several assorted cleanups of ACPI drivers and
PNP code.
Specifics:
- Add SoundWire File Table (SWFT) signature to ACPICA (Maciej Strozek)
- Rearrange local variable definition involving #ifdef in ACPICA to
avoid using uninitialized variables (Zhe Qiao)
- Allow ACPICA to skip Global Lock initialization (Huacai Chen)
- Apply ACPI_NONSTRING in more places in ACPICA and fix two regressions
related to incorrect ACPI_NONSTRING usage (Ahmed Salem)
- Fix printing CDAT table header when disassembling CDAT AML (Ahmed
Salem)
- Use acpi_ds_clear_operands() in acpi_ds_call_control_method() in
ACPICA (Hans de Goede)
- Update dsmethod.c in ACPICA to address unused variable warning (Saket
Dumbre)
- Print error messages in ACPICA for too few or too many control method
arguments (Saket Dumbre)
- Update ACPICA version to 20250807 (Saket Dumbre)
- Fix largest possible resource descriptor index in ACPICA (Dmitry
Antipov)
- Add Back-Invalidate restriction to CXL Window for CEDT in ACPICA
(Davidlohr Bueso).
- Add the package type to acceptable Arg3 types for _DSM in ACPICA
because ACPI_TYPE_ANY does not cover it (Saket Dumbre)
- Fix return values in ap_is_valid_checksum() in the acpidump utility
in ACPICA (Kaushlendra Kumar)
- Add Intel CVS ACPI HIDs to acpi_ignore_dep_ids[] so it is not
regarded as real dependency (Hans de Goede)
- Use ACPI_FREE() for freeing an ACPI object in description_show() in
the ACPI sysfs-related code (Kaushlendra Kumar)
- Fix memory leak in the ACPI processor idle driver registration error
code path and optimize ACPI idle driver registration (Huisong Li,
Rafael Wysocki)
- Add module import namespace to the ACPI processor idle driver (Rafael
Wysocki)
- Eliminate static variable flat_state_cnt from the ACPI processor idle
driver (Rafael Wysocki)
- Release cpufreq policy references using __free() in the ACPI
processor thermal driver (Zihuan Zhang)
- Remove unused empty stubs of some functions and rearrange function
declarations in a header file in the ACPI processor driver (Huisong
Li)
- Redefine two functions as void in the ACPI processor driver (Rafael
Wysocki)
- Stop exposing global variable acpi_idle_driver in the ACPI processor
driver (Huisong Li)
- Fix ACPI buffer properties extraction for data-only subnodes
represented as _DSD-equivalent packages (Rafael Wysocki)
- Fix handling of ACPI data-only subnodes represented as _DSD-equivalent
packages in the case when they are embedded in larger _DSD-equivalent
packages and clean up acpi_nondev_subnode_extract() (Rafael Wysocki)
- Skip ACPI IRQ override on ASUS Vivobook Pro N6506CU (Sam van Kampen)
- Add power resource init function and use it for introducing an HP
EliteBook 855 G7 WWAN modem power resource quirk (Maciej Szmigiero)
- Add support for DBG2 RISC-V SBI port subtype and Precise Baud Rate
field to the ACPI SPCR table parser (Chen Pei)
- Eliminate a dummy local variable from the ACPI thermal driver (Rafael
Wysocki)
- Fold two simple functions into their only caller in the ACPI fan
driver (Rafael Wysocki)
- Force native backlight on Lenovo 82K8 in the ACPI backlight (video)
driver (Mario Limonciello)
- Add missing sysfs_remove_group() for ACPI_TAD_RT (Daniel Tang)
- Skip PRM handlers with NULL handler_address or NULL VA in the ACPI
PRM driver (Shang song)
- Remove redundant assignments in erst_dbg_{ioctl|write}() in the ACPI
APEI driver (Thorsten Blum)
- Allow the ACPI APEI EINJ to handle more types of addresses than just
MMIO (Jiaqi Yan)
- Use str_low_high() helper in two places in the ACPI code (Chelsy
Ratnawat)
- Use str_plural() to simplify the PNP code (Xichao Zhao)
- Fix signedness issues in read/write helpers in the ACPI AML debugger
interface (Amir Mohammad)
Thanks!
