platform/x86: hp-wmi: Add support for Omen 16-wf1xxx (8C77)

The HP Omen 16-wf1xxx (board ID: 8C77) has the same WMI interface as other Victus S boards, but requires quirks for correctly switching thermal profile. Add the DMI board name to victus_s_thermal_profile_boards[] table and map it to omen_v1_thermal_params. Testing on board 8C77 confirmed that platform profile is registered successfully and fan RPMs are readable and controllable.

platform/x86: hp-wmi: Add support for OMEN MAX 16-ak0xxx (8D87)

2026-04-14T16:00:14+00:00

The HP OMEN MAX 16-ak0xxx (8D87) requires the same WMI queries as other Victus S devices, hence it has been added to the corresponding list. For this reason, platform_profile_victus_s_get_ec() will be called during thermal_profile_setup() and victus_s_powersource_event() to obtain hardware state (platform profile) by reading from the Embedded Controller, however, this particular board's EC does not seem to expose the platform profile value, unlike other boards. Hence EC readback is disabled. Testing on board 8D87 confirmed that platform profile is registered successfully and fan RPMs are readable and controllable.

platform/x86: hp-wmi: fix fan table parsing

2026-04-14T16:00:11+00:00

For Victus S devices, the BIOS fan table header was being incorrectly parsed as: struct { u8 unknown; u8 num_entries; } The first field should be num_fans and the second should be unknown. It is pure coincidence that interpreting an "unknown" field as "num_entries" worked on multiple device, however for board 8D87 (in an upcoming patch), this assumption fails, and the hp-wmi driver fails to load. We fix this by correcting the header definition and compensating for num_entries by parsing each entry of the fan table until an all-NULL row is obtained, mirroring the behavior of OMEN Gaming Hub on Windows.

Pull 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.

platform/x86: hp-wmi: add Omen 14-fb0xxx (board 8C58) support

2026-04-13T11:11:29+00:00

Board 8C58 (HP Omen Transcend Gaming Laptop 14-fb0xxx) appears to use the same thermal profile handling as other supported Omen systems, including board 8E41. Add it to omen_thermal_profile_boards so hp-wmi can expose the firmware thermal profiles through the platform_profile interface. Tested on Omen 14-fb0xxx: the profile handler exposes cool, balanced, and performance modes, and selecting performance increases sustained CPU package power under load.
