Tue, 14 Apr 2026 04:25:07 +0200

Merge tag 'acpi-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pmPull ACPI support updates from Rafael Wysocki: "These include an update of the CMOS RTC driver and the related ACPI and x86 code that, among other things, switches it over to using the platform device interface for device binding on x86 instead of the PNP device driver interface (which allows the code in question to be simplified quite a bit), a major update of the ACPI Time and Alarm Device (TAD) driver adding an RTC class device interface to it, and updates of core ACPI drivers that remove some unnecessary and not really useful code from them. Apart from that, two drivers are converted to using the platform driver interface for device binding instead of the ACPI driver one, which is slated for removal, support for the Performance Limited register is added to the ACPI CPPC library and there are some janitorial updates of it and the related cpufreq CPPC driver, the ACPI processor driver is fixed and cleaned up, and NVIDIA vendor CPER record handler is added to the APEI GHES code. Also, the interface for obtaining a CPU UID from ACPI is consolidated across architectures and used for fixing a problem with the PCI TPH Steering Tag on ARM64, there are two updates related to ACPICA, a minor ACPI OS Services Layer (OSL) update, and a few assorted updates related to ACPI tables parsing. Specifics: - Update maintainers information regarding ACPICA (Rafael Wysocki) - Replace strncpy() with strscpy_pad() in acpi_ut_safe_strncpy() (Kees Cook) - Trigger an ordered system power off after encountering a fatal error operator in AML (Armin Wolf) - Enable ACPI FPDT parsing on LoongArch (Xi Ruoyao) - Remove the temporary stop-gap acpi_pptt_cache_v1_full structure from the ACPI PPTT parser (Ben Horgan) - Add support for exposing ACPI FPDT subtables FBPT and S3PT (Nate DeSimone) - Address multiple assorted issues and clean up the code in the ACPI processor idle driver (Huisong Li) - Replace strlcat() in the ACPI processor idle drive with a better alternative (Andy Shevchenko) - Rearrange and clean up acpi_processor_errata_piix4() (Rafael Wysocki) - Move reference performance to capabilities and fix an uninitialized variable in the ACPI CPPC library (Pengjie Zhang) - Add support for the Performance Limited Register to the ACPI CPPC library (Sumit Gupta) - Add cppc_get_perf() API to read performance controls, extend cppc_set_epp_perf() for FFH/SystemMemory, and make the ACPI CPPC library warn on missing mandatory DESIRED_PERF register (Sumit Gupta) - Modify the cpufreq CPPC driver to update MIN_PERF/MAX_PERF in target callbacks to allow it to control performance bounds via standard scaling_min_freq and scaling_max_freq sysfs attributes and add sysfs documentation for the Performance Limited Register to it (Sumit Gupta) - Add ACPI support to the platform device interface in the CMOS RTC driver, make the ACPI core device enumeration code create a platform device for the CMOS RTC, and drop CMOS RTC PNP device support (Rafael Wysocki) - Consolidate the x86-specific CMOS RTC handling with the ACPI TAD driver and clean up the CMOS RTC ACPI address space handler (Rafael Wysocki) - Enable ACPI alarm in the CMOS RTC driver if advertised in ACPI FADT and allow that driver to work without a dedicated IRQ if the ACPI alarm is used (Rafael Wysocki) - Clean up the ACPI TAD driver in various ways and add an RTC class device interface, including both the RTC setting/reading and alarm timer support, to it (Rafael Wysocki) - Clean up the ACPI AC and ACPI PAD (processor aggregator device) drivers (Rafael Wysocki) - Rework checking for duplicate video bus devices and consolidate pnp.bus_id workarounds handling in the ACPI video bus driver (Rafael Wysocki) - Update the ACPI core device drivers to stop setting acpi_device_name() unnecessarily (Rafael Wysocki) - Rearrange code using acpi_device_class() in the ACPI core device drivers and update them to stop setting acpi_device_class() unnecessarily (Rafael Wysocki) - Define ACPI_AC_CLASS in one place (Rafael Wysocki) - Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver to bind to platform devices instead of ACPI devices (Rafael Wysocki) - Add devm_ghes_register_vendor_record_notifier(), use it in the PCI hisi driver, and Add NVIDIA vendor CPER record handler (Kai-Heng Feng) - Consolidate the interface for obtaining a CPU UID from ACPI across architectures and use it to address incorrect PCI TPH Steering Tag on ARM64 resulting from the invalid assumption that the ACPI Processor UID would always be the same as the corresponding logical CPU ID in Linux (Chengwen Feng)"* tag 'acpi-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (73 commits) ACPICA: Update maintainers information watchdog: ni903x_wdt: Convert to a platform driver ACPI: PAD: xen: Convert to a platform driver ACPI: processor: idle: Reset cpuidle on C-state list changes cpuidle: Extract and export no-lock variants of cpuidle_unregister_device() PCI/TPH: Pass ACPI Processor UID to Cache Locality _DSM ACPI: PPTT: Use acpi_get_cpu_uid() and remove get_acpi_id_for_cpu() perf: arm_cspmu: Switch to acpi_get_cpu_uid() from get_acpi_id_for_cpu() ACPI: Centralize acpi_get_cpu_uid() declaration in include/linux/acpi.h x86/acpi: Add acpi_get_cpu_uid() for unified ACPI CPU UID retrieval RISC-V: ACPI: Add acpi_get_cpu_uid() for unified ACPI CPU UID retrieval LoongArch: Add acpi_get_cpu_uid() for unified ACPI CPU UID retrieval arm64: acpi: Add acpi_get_cpu_uid() for unified ACPI CPU UID retrieval ACPI: APEI: GHES: Add NVIDIA vendor CPER record handler PCI: hisi: Use devm_ghes_register_vendor_record_notifier() ACPI: APEI: GHES: Add devm_ghes_register_vendor_record_notifier() ACPI: tables: Enable FPDT on LoongArch ACPI: processor: idle: Fix NULL pointer dereference in hotplug path ACPI: processor: idle: Reset power_setup_done flag on initialization failure ACPI: TAD: Add alarm support to the RTC class device interface ...

Wed, 01 Apr 2026 15:53:12 +0200

ACPI: tables: Enable FPDT on LoongArchFPDT provides system- and application-readable performance statistics,useful for profiling and analyzing boot-time performance. FPDT tablesupport is now available as a pending patch at the EDK II upstream [1]and has been tested on real hardware such as Loongson XA61200_V1.1 andXB612B0_V1.2 with patched firmware.We have also cross checked systemd-analyze(1) against a stop watch andthe `dp' command in EFI Shell to see that the timing information arecorrect.Now that the functionality of FPDT is verified on LoongArch hardware,list LOONGARCH as a possible dependency, allowing it to be enabled.Link: https://github.com/tianocore/edk2/pull/12378 [1]Signed-off-by: Xi Ruoyao [ rjw: Subject tweak ]Link: https://patch.msgid.link/20260401135311.1737958-2-xry111@xry111.siteSigned-off-by: Rafael J.
