Merge ACPI IRQ management fix for 6.6-rc7 (Sunil V L). * acpi-irq: ACPI: irq: Fix incorrect return value in acpi_register_gsi()
2023-10-18ACPI: bus: Move acpi_arm_init() to the place of after acpi_ghes_init()Hanjun Guo1-1/+1
acpi_agdi_init() in acpi_arm_init() will register a SDEI event, so it needs the SDEI subsystem to be initialized (which is done in acpi_ghes_init()) before the AGDI driver probing. In commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific initialisation into acpi_arm_init()"), the acpi_agdi_init() was called before acpi_ghes_init() and it causes following failure: | [ 0.515864] sdei: Failed to create event 1073741825: -5 | [ 0.515866] agdi agdi.0: Failed to register for SDEI event 1073741825 | [ 0.515867] agdi: probe of agdi.0 failed with error -5 | ... | [ 0.516022] sdei: SDEIv1.0 (0x0) detected in firmware.

2023-10-18ACPI: irq: Fix incorrect return value in acpi_register_gsi()Sunil V L1-1/+6
acpi_register_gsi() should return a negative value in case of failure. Currently, it returns the return value from irq_create_fwspec_mapping(). However, irq_create_fwspec_mapping() returns 0 for failure. Fix the issue by returning -EINVAL if irq_create_fwspec_mapping() returns zero.

2023-10-11cpu-hotplug: Provide prototypes for arch CPU registrationRussell King (Oracle)1-0/+1
Provide common prototypes for arch_register_cpu() and arch_unregister_cpu(). These are called by acpi_processor.c, with weak versions, so the prototype for this is already set. It is generally not necessary for function prototypes to be conditional on preprocessor macros. Some architectures (e.g. Loongarch) are missing the prototype for this, and rather than add it to Loongarch's asm/cpu.h, do the job once for everyone. Since this covers everyone, remove the now unnecessary prototypes in asm/cpu.h, and therefore remove the 'static' from one of ia64's arch_register_cpu() definitions.

irq1_edge_low_force_override[] The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang barebone design which is sold under various brand names. The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen laptops in order for the IRQ to work. Adjust the pcspecialist_laptop[] DMI match table for this: 1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16 entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match the laptop when sold by other vendors such as hyperbook.pl. 2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060) models. Note the .ident values of the dmi_system_id structs are left unset since these are not used.

2023-10-04cpuidle, ACPI: Evaluate LPI arch_flags for broadcast timerOza Pawandeep1-2/+1
Arm® Functional Fixed Hardware Specification defines LPI states, which provide an architectural context loss flags field that can be used to describe the context that might be lost when an LPI state is entered. - Core context Lost - General purpose registers. - Floating point and SIMD registers. - System registers, include the System register based - generic timer for the core. - Debug register in the core power domain. - PMU registers in the core power domain. - Trace register in the core power domain. - Trace context loss - GICR - GICD Qualcomm's custom CPUs preserves the architectural state, including keeping the power domain for local timers active. when core is power gated, the local timers are sufficient to wake the core up without needing broadcast timer. The patch fixes the evaluation of cpuidle arch_flags, and moves only to broadcast timer if core context lost is defined in ACPI LPI.

acpi_video_bus_add_notify_handler() could free video->input and set it to NULL on failure, but this failure would be missed in its caller acpi_video_bus_add(). As a result, when an error happens in acpi_dev_install_notify_handler(), acpi_video_bus_add() would call acpi_video_bus_remove_notify_handler(), where a potential NULL pointer video->input is dereferenced in input_unregister_device().

2023-08-29thermal: core: Rework .get_trend() thermal zone callbackRafael J. Wysocki1-23/+18
Passing a struct thermal_trip pointer instead of a trip index to the .get_trend() thermal zone callback allows one of its 2 implementations, the thermal_get_trend() function in the ACPI thermal driver, to be simplified quite a bit, and the other implementation of it in the ti-soc-thermal driver does not even use the relevant callback argument. For this reason, change the .get_trend() thermal zone callback definition and adjust the related code accordingly. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

This means these calls can no longer occur concurrently with EFI runtime calls, and will be made from the EFI runtime workqueue. It also means any page faults occurring during PRM handling will be identified correctly as originating in firmware code. Acked-by: Rafael J.

2023-08-22efi/runtime-wrappers: Remove duplicated macro for service returning voidArd Biesheuvel1-1/+1
__efi_call_virt() exists as an alternative for efi_call_virt() for the sole reason that ResetSystem() returns void, and so we cannot use a call to it in the RHS of an assignment. Given that there is only a single user, let's drop the macro, and expand it into the caller. That way, the remaining macro can be tightened somewhat in terms of type safety too. Note that the use of typeof() on the runtime service invocation does not result in an actual call being made, but it does require a few pointer types to be fixed up and converted into the proper function pointer prototypes.

But there are platforms with SystemCMOS Operetion Region defined under the ACPI Time and Alarm Device (ACPI000E), which is used by the ACPI pre-defined control methods like _GRT (Get the Real time) and _SRT (Set the Real time). When accessing these control methods via the acpi_tad sysfs interface, missing SystemCMOS address space handler causes errors like below [ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130) [ 478.255458] ACPI Error: Region SystemCMOS (ID=5) has no handler (20230331/exfldio-261) [ 478.255461] Initialized Local Variables for Method [_GRT]: [ 478.255461] Local1: 00000000f182542c <Obj> Integer 0000000000000000 [ 478.255464] No Arguments are initialized for method [_GRT] [ 478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous error (AE_NOT_EXIST) (20230331/psparse-529) Export two APIs for SystemCMOS address space handler from acpi_cmos_rtc scan handler and install the handler for the ACPI Time and Alarm Device from the ACPI TAD driver.

2023-08-17ACPI: video: Put ACPI video and its child devices into D0 on bootKai-Heng Feng1-0/+6
Screen brightness can only be changed once on HP ZBook Fury 16 G10. The vendor reports that the issue is related to the fact that Linux doesn't invoke _PS0 at boot for all ACPI devices, as expected by the platform firmware: Scope (\_SB.PC00.GFX0) { Scope (DD1F) { Method (_PS0, 0, Serialized) // _PS0: Power State 0 { If (CondRefOf (\_SB.PC00.LPCB.EC0.SSBC)) { \_SB.PC00.LPCB.EC0.SSBC () } } ... } ... } The \_SB.PC00.GFX0.DD1F is the panel device, and its _PS0 needs to be executed at the initialization time to make the brightness control work properly. _PS0 is not evaluated for this device, because _PSC is missing, which violates the ACPI specification (ACPI 6.5, section 7.3.6). Commit b3785492268f ("ACPI / PM: Do not power manage devices in unknown initial states") tried to work around missing _PSC on platforms with defective firmware, but got reverted due to a regression. So the safest approach is to use acpi_device_fix_up_power_extended() to put ACPI video and its child devices to D0 to address the issue at hand.

2023-08-17ACPI: processor: LoongArch: Get physical ID from MADTBibo Mao1-0/+29
With ACPI Spec 6.5 chapter 5.2.12.20, each processor in LoongArch systems has a Core Programmable Interrupt Controller in MADT. The value of its type is 0x11 in the spec and defined as enum variable ACPI_MADT_TYPE_CORE_PIC in the Linux kernel. Physical IDs can be retrieved from MADT for LoongArch systems during initialization and they can be retrieved from the _MAT output for hotplug CPUs. Add physical CPU ID enumeration for LoongArch systems. Signed-off-by: Bibo Mao <maobibo@loongson.cn> [ rjw: Subject and changelog edits ] Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2023-08-17ACPI: scan: Defer enumeration of devices with a _DEP pointing to IVSC deviceWentong Wu1-0/+3
Inside IVSC, switching ownership requires an interface with two different hardware modules, ACE and CSI. The software interface to these modules is based on Intel MEI framework. Usually mei client devices are dynamically created, so the info of consumers depending on mei client devices is not present in the firmware tables. This causes problems with the probe ordering with respect to drivers for consumers of these MEI client devices. But on these camera sensor devices, the ACPI nodes describing the sensors all have a _DEP dependency on the matching MEI bus ACPI device, so adding IVSC MEI bus ACPI device to acpi_honor_dep_ids allows solving the probe-ordering problem by deferring the enumeration of ACPI-devices which have a _DEP dependency on an IVSC mei bus ACPI device. On TGL platform, the HID of IVSC MEI bus ACPI device is INTC1059, and on ADL platform, the HID is INTC1095. So add both of them to acpi_honor_dep_ids.

2023-08-17ACPI: thermal: Eliminate code duplication from acpi_thermal_notify()Rafael J. Wysocki1-10/+10
Move the acpi_bus_generate_netlink_event() invocation into acpi_thermal_trips_update() which allows the code duplication in acpi_thermal_notify() to be cleaned up, but for this purpose the event value needs to be passed to acpi_thermal_trips_update() and from there to acpi_thermal_adjust_thermal_zone() which has to determine the flag value for __acpi_thermal_trips_update() by itself.
