Subject: [GIT PULL] ACPI updates for v6.16-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-6.16-rc1
with top-most commit db0e4d5429c909db9c252be59bd872ab628c78c6
Merge branches 'acpi-resource', 'acpi-pm', 'acpi-platform-profile'
and 'acpi-docs'
on top of commit a5806cd506af5a7c19bcd596e4708b5c464bfd21
Linux 6.15-rc7
to receive ACPI updates for 6.16-rc1.
The most significant part of these changes is an ACPICA update covering
two upstream ACPICA releases, 20241212 and 20250404, that have not been
included into the kernel code base yet. Among other things, it adds
definitions needed to address GCC 15's -Wunterminated-string-initialization
warnings, adds support for three new tables (MRRM, ERDT, RIMT), extends
support for two tables (RAS2, DMAR), and fixes some issues.
On top of the above, there is a new parser for the MRRM table, more
changes related to GCC 15's -Wunterminated-string-initialization
warnings, a CPPC library update including functions related to
autonomous CPU performance state selection, a couple of new quirks,
some assorted fixes and some code cleanups.
Specifics:
- Fix two ACPICA SLAB cache leaks (Seunghun Han).
- Add EINJv2 get error type action and define Error Injection Actions
in hex values to avoid inconsistencies between the specification and
the code (Zaid Alali).
- Fix typo in comments for SRAT structures (Adam Lackorzynski).
- Prevent possible loss of data in ACPICA because of u32 to u8
conversions (Saket Dumbre).
- Fix reading FFixedHW operation regions in ACPICA (Daniil Tatianin).
- Add support for printing AML arguments when the ACPICA debug level is
ACPI_LV_TRACE_POINT (Mario Limonciello).
- Drop a stale comment about the file content from actbl2.h (Sudeep
Holla).
- Apply pack(1) to union aml_resource (Tamir Duberstein).
- Fix overflow check in the ACPICA version of vsnprintf() (gldrk).
- Interpret SIDP structures in DMAR added revision 3.4 of the VT-d
specification (Alexey Neyman).
- Add typedef and other definitions related to MRRM to ACPICA (Tony
Luck).
- Add definitions for RIMT to ACPICA (Sunil V L).
- Fix spelling mistake "Incremement" -> "Increment" in the ACPICA
utilities code (Colin Ian King).
- Add typedef and other definitions for ERDT to ACPICA (Tony Luck).
- Introduce ACPI_NONSTRING and use it (Kees Cook, Ahmed Salem).
- Rename structure and field names of the RAS2 table in actbl2.h (Shiju
Jose).
- Fix up whitespace in acpica/utcache.c (Zhe Qiao).
- Avoid sequence overread in a call to strncmp() in ap_get_table_length()
and replace strncpy() with memcpy() in ACPICA in some places (Ahmed
Salem).
- Update copyright year in all ACPICA files (Saket Dumbre).
- Add __nonstring annotations for unterminated strings in the static
ACPI tables parsing code (Kees Cook).
- Add support for parsing the MRRM ACPI table and sysfs files to
describe memory regions listed in it (Tony Luck, Anil Keshavamurthy).
- Remove an (explicitly) unused header file include from the VIOT ACPI
table parser file (Andy Shevchenko).
- Improve logging around acpi_initialize_tables() (Bartosz Szczepanek).
- Clean up the initialization of CPU data structures in the ACPI
processor driver (Zhang Rui).
- Remove an obsolete comment regarding the C-states handling in the
ACPI processor driver (Giovanni Gherdovich).
- Simplify PCC shared memory region handling (Sudeep Holla).
- Rework and extend functions for reading CPPC register values and for
updating CPPC registers (Lifeng Zheng).
- Add three functions related to autonomous CPU performance state
selection to the CPPC library (Lifeng Zheng).
- Turn the acpi_pci_root_remap_iospace() fwnode_handle parameter into a
const pointer (Pei Xiao).
- Round battery capacity percengate in the ACPI battery driver to the
closest integer to avoid user confusion (shitao).
- Make the ACPI battery driver report the current as a negative number
to the power supply framework when the battery is discharging as
documented (Peter Marheine).
- Add TUXEDO InfinityBook Pro AMD Gen9 to the acpi_ec_no_wakeup[] list
to prevent spurious wakeups from suspend-to-idle (Werner Sembach).
- Convert the APEI EINJ driver to a faux device one (Sudeep Holla, Jon
Hunter).
- Remove redundant calls to einj_get_available_error_type() from the
APEI EINJ driver (Zaid Alali).
- Fix a typo for MECHREVO in irq1_edge_low_force_override[] (Mingcong
Bai).
- Add an LPS0 check() callback to the AMD pinctrl driver and fix up
config symbol dependencies in it (Mario Limonciello, Rafael Wysocki).
- Avoid initializing the ACPI platform profile driver on non-ACPI
platforms (Alexandre Ghiti).
- Document that references to ACPI data (non-device) nodes should use
string-only references in hierarchical data node packages (Sakari
Ailus).
- Fail the ACPI bus registration if acpi_kobj registration fails (Armin
Wolf).
Thanks!
