From: Linus Torvalds Date: Tue, 18 Aug 2026 15:29:30 +0000 (-0700) Subject: Merge tag 'acpi-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael... X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=0d508f1745b57272d4d4a3d50dc35aa2a3682238;p=thirdparty%2Flinux.git Merge tag 'acpi-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI support updates from Rafael Wysocki: "The most significant change here is the elimination of struct acpi_driver that has no more users in the tree now along with some documentation related to it, and a follow-up update to set the "no PM" flag for all ACPI devices that are now only going to play the role of other devices' "companions" (in analogy with DT nodes). There is also a significant update of irqchip code related to ACPI done in order to enable GICv5 IWB ACPI probe ordering detection on ARM, which involves RISC-V interrupt controller management code refactoring to extract generic code from it into the common ACPI IRQ code. The rest is mostly fixes, including some fallout of the _OSC handling rework in 7.0, ACPI CPPC library fixes, a workaround for registering ACPI platform devices with overlapping I/O or memory resources, an ACPI EC driver fix related to probe deferral on platforms using HW-reduced ACPI, two ACPI battery driver fixes and a workaround for handling model numbers with unprintable characters in it, probe error cleanup and driver unload code path fixes, hardware error reporting fixes, documentation fixes, and assorted code cleanups all over. Specifics: - Eliminate struct acpi_driver whose users have all been converted to bind to platform devices or auxiliary devices and set the "no power management" flag for all struct acpi_device objects (Rafael Wysocki) - Avoid complaints regarding missing _OSC features on platforms where OSC_CAPABILITIES_MASK_ERROR is set in _OSC error bits even though all of the requested features are actually acknowledged (Rafael Wysocki) - Avoid printing confusing _OSC messages for non-PCIe host bridges without _OSC which is a valid configuration (Kazuma Kondo) - Use correct region struct for BERT region size check and properly map BERT and CCEL data to their ACPI tables (Thomas Renninger) - Add acpi_device_clear_deps(), refactor RISC-V interrupt controller management code to extract generic code from it into the common ACPI IRQ code, and enable GICv5 IWB ACPI probe ordering detection on ARM on top of that (Lorenzo Pieralisi) - Stop using acpi_device_name() in the PNP core, stop setting acpi_device_name/class() in the Xen variant of the ACPI PAD (Processor Aggregator Device) driver, and make the Loongarch laptop driver stop setting acpi_device_class() (Rafael Wysocki) - Fix issues related to the desired_perf register access in the ACPI CPPC library and update it to avoid unnecessary overhead (Christian Loehle) - Simplify acpi_get_pci_dev() with the help of a mutex guard, introduce acpi_dev_get_pci_dev() for code that has a struct ACPI device for which it wants to get the struct pci_dev pointer of the associated PCI device, and use it in the ACPI video bus driver (Rafael Wysocki) - Avoid registering platform devices with resource overlaps in the ACPI core device enumeration code (Rafael Wysocki) - Clean up the list of included header files in the NHLT table parser and validate the table and record lengths in the FPDT parser (Andy Shevchenko and Pengpeng Hou) - Unregister the cpufreq notifier on init failure in the ACPI processor driver (Can Peng) - Validate MADT IOAPIC entry bounds during IOAPIC hotplug lookup in the ACPI processor driver (Pengpeng Hou) - Avoid _REG disconnect on probe deferrals related to GPIO IRQ in the ACPI EC driver (Zhu Ling) - Update kerneldoc comments of two structures in the ACPI bus type code to use correct struct member names to avoid warnings (Randy Dunlap) - Use a correct function parameter name in kernel-doc in the ACPI fan driver (Randy Dunlap) - Update ACPI fan IDs to follow modern style and clean up header file inclusions in the ACPI fan driver (Andy Shevchenko) - Use devm_acpi_install_notify_handler() to replace a custom open-coded devres-based management of an ACPI notify handler in the ACPI fan driver (Rafael Wysocki) - Adjust charging status validation check in the ACPI battery driver to avoid incorrect status reporting (Rafael Wysocki) - Merge consecutive battery notifications in the ACPI battery driver to reduce the pressure on STA, _BST and _BIX/_BIF ACPI control methods and make that driver use kstrtoul() instead of sscanf("%lu\n") (Rong Zhang) - Sanitise model_number in the ACPI battery driver by dropping unprintable characters (Kate Hsuan) - Remove a node_set() call that is redundant from acpi_parse_memory_affinity() (Sang-Heon Jeon) - Prevent kernel-doc warnings by converting 2 function description comments to kernel-doc format (Randy Dunlap) - Fix docs build error in the ACPI admin-guide documentation (Randy Dunlap) - Replace __get_free_page() with kmalloc() in the code handling ACPI NVS memory during system suspend/resume (Mike Rapoport) - Fix card device cleanup on registration failure in the core PNP code (Yuho Choi) - Drop an unused assignment of pnp_device_id driver data (Uwe Kleine-König) - Clear driver_data on all paths that free acpi_pci_root in acpi_pci_root_add() (Chen Pei) - Add locking around evaluation of ACPI control methods in the ACPI TAD driver to avoid race conditions (Rafael Wysocki) - Handle repeated SEA error storms in APEI (Junhao He) - Fix ERST timeout unit conversion in APEI (Nirmoy Das) - Fix ARM section length accounting after header in the ACPI APEI GHES driver (TanZheng) - Mark ghes_in_nmi_spool_from_list() as maybe unused (Rui Qi) - Introduce helper function acpi_dev_is_video_device() and use it in the core ACPI device enumeration code, in the ACPI video bus driver, in the ACPI support code for I2C, in the PCI VGA driver, and in the x86 platform thinkpad_acpi driver (Andy Shevchenko) - Add a quirk to use the native backlight on Acer Nitro AN515-46 to the ACPI video bus driver (Marcos Paulo Medeiros) - Release PCI device reference after lookup in video_detect_portege_r100() in the ACPI video bus driver (Yuho Choi)" * tag 'acpi-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (61 commits) ACPI: scan: Avoid registering platform devices with resource overlaps ACPI: APEI: Handle repeated SEA error storms ACPI: APEI: Fix ERST timeout unit conversion ACPI: APEI: GHES: fix ARM section length accounting after header ACPI: video: Release PCI device reference after lookup ACPI: PCI: Avoid misleading _OSC messages for non-PCIe host bridges without _OSC ACPI: TAD: Add locking around AML evaluations ACPI: video: force native backlight on Acer Nitro AN515-46 ACPI: CPPC: Evaluate performance-control PCC use once ACPI: CPPC: Avoid locking standalone full-width registers ACPI: CPPC: Avoid unnecessary reads for full-width writes ACPI: CPPC: Stop reading desired_perf in cppc_get_perf() ACPI: CPPC: Skip desired_perf read in cppc_get_perf() ACPI: CPPC: Reject desired_perf reads on _CPC revision 4+ ACPI: processor: Unregister cpufreq notifier on init failure ACPI: bus: Avoid confusing complaints regarding missing _OSC features ACPI: battery: Adjust charging status validation check ACPI: pmtmr: Convert to kernel-doc format ACPI: bus: Use correct struct member names ACPI: fan: Use correct function parameter name in kernel-doc ... --- 0d508f1745b57272d4d4a3d50dc35aa2a3682238
