Subject: [GIT PULL] ACPI support updates for v6.19-rc1
Hi Linus,
I am sending this in advance because I am not expecting to make any changes
to it before next week.
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-6.19-rc1
with top-most commit af47d98064e900f279c98bb3bb57445a1e7a8f6b
Merge branches 'acpi-misc' and 'pnp'
on top of commit fbf04215d9966da61feee3f4ec24dbf4544cfd0f
Revert "ACPI: processor: Update cpuidle driver check in
__acpi_processor_start()"
to receive ACPI support updates for 6.19-rc1.
These add Microsoft fan extensions support to the ACPI fan driver,
fix a bug in ACPICA, update other ACPI drivers (processor, time and
alarm device), update ACPI power management code and ACPI device
properties management, and fix an ACPI utility:
- Avoid walking the ACPI namespace in the AML interpreter if the
starting node cannot be determined (Cryolitia PukNgae)
- Use min() instead of min_t() in the ACPI device properties handling
code to avoid discarding significant bits (David Laight)
- Fix potential fwnode refcount leak in acpi_fwnode_graph_parse_endpoint()
that may prevent the parent fwnode from being released (Haotian Zhang)
- Rework acpi_graph_get_next_endpoint() to use ACPI functions only, remove
unnecessary conditionals from it to make it easier to follow, and make
acpi_get_next_subnode() static (Sakari Ailus)
- Drop unused function acpi_get_lps0_constraint(), make some Low-Power
S0 callback functions for suspend-to-idle static, and rearrange the
code retrieving Low-Power S0 constraints so it only runs when the
constraints are actually used (Rafael Wysocki)
- Drop redundant locking from the ACPI battery driver (Rafael Wysocki)
- Improve runtime PM in the ACPI time and alarm device (TAD) driver
using guard macros and rearrange code related to runtime PM in
acpi_tad_remove() (Rafael Wysocki)
- Add support for Microsoft fan extensions to the ACPI fan driver along
with notification support and work around a 64-bit firmware bug in
that driver (Armin Wolf)
- Use ACPI_FREE() to free ACPI buffer in the ACPI DPTF code (Kaushlendra
Kumar)
- Fix a memory leak and a resource leak in the ACPI pfrut utility (Malaya
Kumar Rout)
- Replace `core::mem::zeroed` with `pin_init::zeroed` in the ACPI Rust
code (Siyuan Huang)
- Update the ACPI code to use the new style of allocating workqueues
and new global workqueues (Marco Crivellari)
- Fix two spelling mistakes in the ACPI code (Chu Guangqing)
- Fix ISAPNP to generate uevents to auto-load modules (René Rebe)
- Relocate the state flags initialization in the ACPI processor idle
driver and drop redundant C-state count checks from it (Huisong Li)
- Fix map_x2apic_id() in the ACPI processor core driver for amd-pstate
on am4 (René Rebe)
Thanks!
