| | * | | ACPI: NHLT: Streamline struct namingCezary Rojewski2024-03-272-34/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Few recently introduced structs are named 'nhlt2' instead of 'nhlt' to avoid naming conflicts.

Most of the operations involve iterating over elements of the table and filtering them. Simplify the process by implementing range of getters. While the acpi_nhlt_endpoint_mic_count() stands out a bit, it is a critical component for any AudioDSP driver to know how many digital microphones it is dealing with.

This task is important as same set of hardware registers can be used with different topologies and vice versa, same topology could be utilized with different set of hardware. As the hardware registers description is directly tied to specific platform, intention is to have such description part of low-level firmware e.g.: BIOS. The initial design has been provided in early Sky Lake (SKL) days. The audio architecture goes by the name cAVS. SKL is a representative of cAVS 1.5. The table helps describe endpoint capabilities ever since. While Raptor Lake (RPL) is the last of cAVS architecture - cAVS 2.5 to be precise - its successor, the ACE architecture which begun with Meteor Lake (MTL) inherited the design for all I2S and PDM configurations. These two configurations are the primary targets for NHLT table. Due to naming conflicts with existing code, several structs are named 'nhlt2' rather than 'nhlt'. Follow up changes clean this up once existing code has no users and is removed.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modules registering driver with acpi_bus_register_driver() often forget to set .owner field. The field is used by some of other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core ACPI bus code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register").

Fix this using _Generic(), which will allow NULL @uid2 argument for string types as well as _UID matching for all possible integer values.

This UART has a DELL0501 HID with CID set to PNP0501 so that the UART is still handled by 8250_pnp.c. Unfortunately there is no separate ACPI device with an UartSerialBusV2() resource to model the backlight-controller. The next patch in this series will use acpi_quirk_skip_serdev_enumeration() to still create a serdev for this for a backlight driver to bind to instead of creating a /dev/ttyS0. This new acpi_quirk_skip_serdev_enumeration() use is not limited to Android X86 tablets, so move it out of the ifdef CONFIG_X86_ANDROID_TABLETS block.

| * iommu: Retire bus opsRobin Murphy2023-11-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the rest of the API internals converted, it's time to finally tackle probe_device and how we bootstrap the per-device ops association to begin with. This ends up being disappointingly straightforward, since fwspec users are already doing it in order to find their of_xlate callback, and it works out that we can easily do the equivalent for other drivers too. Then shuffle the remaining awareness of iommu_ops into the couple of core headers that still need it, and breathe a sigh of relief. Ding dong the bus ops are gone! CC: Rafael J.

Also significant is the switch-over to threaded interrupt handlers for the ACPI SCI and the dedicated EC interrupt (on systems where the former is not used) which essentially allows all ACPI code to run with local interrupts enabled. That should improve responsiveness significantly on systems where multiple GPEs are enabled and the handling of one SCI involves many I/O address space accesses which previously had to be carried out in one go with disabled interrupts on the local CPU. Apart from the above, the ACPI thermal zone driver will use the Thermal fast Sampling Period (_TFP) object if available, which should allow temperature changes to be followed more accurately on some systems, the ACPI Notify () handlers can run on all CPUs (not just on CPU0), which should generally speed up the processing of events signaled through the ACPI SCI, and the ACPI power button driver will trigger wakeup key events via the input subsystem (on systems where it is a system wakeup device) In addition to that, there are the usual bunch of fixes and cleanups. Specifics: - Add CSI-2 and DisCo for Imaging support to the ACPI device enumeration code (Sakari Ailus, Rafael J. Wysocki) - Adjust the cpufreq thermal reduction algorithm in the ACPI processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd Bergmann) - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki) - Switch over ACPI to using a threaded interrupt handler for the SCI (Rafael J. Wysocki) - Allow ACPI Notify () handlers to run on all CPUs and clean up the ACPI interface for deferred events processing (Rafael J. Wysocki) - Switch over the ACPI EC driver to using a threaded handler for the dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki) - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock to keep local interrupts on (Rafael J. Wysocki) - Adjust the USB4 _OSC handshake to correctly handle cases in which certain types of OS control are denied by the platform (Mika Westerberg) - Correct and clean up the generic function for parsing ACPI data-only tables with array structure (Yuntao Wang) - Modify acpi_dev_uid_match() to support different types of its second argument and adjust its users accordingly (Raag Jadav) - Clean up code related to acpi_evaluate_reference() and ACPI device lists (Rafael J. Wysocki) - Use generic ACPI helpers for evaluating trip point temperature objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd Bergmann) - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal zone driver (Jeff Brasen) - Modify the ACPI LPIT table handling code to avoid u32 multiplication overflows in state residency computations (Nikita Kiryushin) - Drop an unused helper function from the ACPI backlight (video) driver and add a clarifying comment to it (Hans de Goede) - Update the ACPI backlight driver to avoid using uninitialized memory in some cases (Nikita Kiryushin) - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo Qiu) - Add support for vendor-defined error types to the ACPI APEI error injection code (Avadhut Naik) - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous memory failure events, so they are handled differently from the asynchronous ones (Shuai Xue) - Fix NULL pointer dereference check in the ACPI extlog driver (Prarit Bhargava) - Adjust the ACPI extlog driver to clear the Extended Error Log status when RAS_CEC handled the error (Tony Luck) - Add IRQ override quirks for some Infinity laptops and for TongFang GMxXGxx (David McFarland, Hans de Goede) - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is not the same as one of the real pxm values (Yuntao Wang) - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC) driver so as to prevent miscalculation of the values in the clock divider (Andy Shevchenko) - Adjust comments in the ACPI watchdog driver to prevent kernel-doc from complaining during documentation builds (Randy Dunlap) - Make the ACPI button driver send wakeup key events to user space in addition to power button events on systems that can be woken up by the power button (Ken Xue) - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full structure field (Dmitry Antipov)" * tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (56 commits) ACPI: resource: Add Infinity laptops to irq1_edge_low_force_override ACPI: button: trigger wakeup key events ACPI: resource: Add another DMI match for the TongFang GMxXGxx ACPI: EC: Use a spin lock without disabing interrupts ACPI: EC: Use a threaded handler for dedicated IRQ ACPI: OSL: Use spin locks without disabling interrupts ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on synchronous events ACPI: utils: Introduce helper for _DEP list lookup ACPI: utils: Fix white space in struct acpi_handle_list definition ACPI: utils: Refine acpi_handle_list_equal() slightly ACPI: utils: Return bool from acpi_evaluate_reference() ACPI: utils: Rearrange in acpi_evaluate_reference() ACPI: arm64: export acpi_arch_thermal_cpufreq_pctg() ACPI: extlog: Clear Extended Error Log status when RAS_CEC handled the error ACPI: LPSS: Fix the fractional clock divider flags ACPI: NUMA: Fix the logic of getting the fake_pxm value ACPI: NUMA: Optimize the check for the availability of node values ACPI: NUMA: Remove unnecessary check in acpi_parse_gi_affinity() ACPI: watchdog: fix kernel-doc warnings ACPI: extlog: fix NULL pointer dereference check ...

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Find ACPI CSI-2 resource descriptors defined since ACPI 6.4 (for CSI-2 and camera configuration) in _CRS for all device objects in the given scope of the ACPI namespace that have them, identify the corresponding "remote endpoint" device objects for them and allocate memory for software nodes needed to create a DT-like data structure representing the CSI-2 connection graph for drivers. The code needed to populate these software nodes will be added by subsequent change sets.

* | / cpufreq/cppc: Move and rename cppc_cpufreq_{perf_to_khz|khz_to_perf}()Vincent Guittot2023-12-231-0/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move and rename cppc_cpufreq_perf_to_khz() and cppc_cpufreq_khz_to_perf() to use them outside cppc_cpufreq in topology_init_cpu_capacity_cppc(). Modify the interface to use struct cppc_perf_caps *caps instead of struct cppc_cpudata *cpu_data as we only use the fields of cppc_perf_caps. cppc_cpufreq was converting the lowest and nominal freq from MHz to kHz before using them. We move this conversion inside cppc_perf_to_khz and cppc_khz_to_perf to make them generic and usable outside cppc_cpufreq.

|/ | | | | | | | | | In some cases it is necessary to fix-up the power-state of an ACPI device's children without touching the ACPI device itself add a new acpi_device_fix_up_power_children() function for this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add void *context arrgument to the list of arguments of acpi_dev_install_notify_handler() and modify it to pass that argument as context to acpi_install_notify_handler() instead of its first argument which is problematic in general (for example, if platform drivers used it, they would rather get struct platform_device pointers or pointers to their private data from the context arguments of their notify handlers). Make all of the current callers of acpi_dev_install_notify_handler() take this change into account so as to avoid altering the general functionality.
