platform/x86: hp-bioscfg: Support allocations of larger data

2026-02-27T11:10:16Z

Some systems have much larger amounts of enumeration attributes than have been previously encountered. This can lead to page allocation failures when using kcalloc(). Switch over to using kvcalloc() to allow larger allocations.

platform/x86: hp-wmi: add Omen 14-fb1xxx (board 8E41) support

2026-02-23T16:01:22Z

Reverse engineering of the HP Omen Windows utility shows that for performance mode it uses the same codes listed in hp_thermal_profile_omen_v1. Therefore it seems sufficient to add the board model name to omen_thermal_profile_boards. Tested on Omen 14-fb1xxx: CPU power in performance profile reaches the Windows limit (65W), instead of 45W in automatic BIOS mode. Max fan speed was reached as well.

platform/x86: hp-wmi: Add Victus 16-d0xxx support

2026-02-23T15:55:11Z

This patch enables Victus thermal profile support for the HP Victus 16-d0xxx. It does so by adding model's DMI board name 88F8 to victus_thermal_profile_boards. Tested on a Victus 16-d0xxx: - Victus thermal profile choices available (quiet, balanced, performance) instead of the default ones (cool, quiet, balanced, performance); - Profile switching works correctly; - About 4% increase in FPS using benchmark Cyberpunk 2077 on performance profile; - No noticeable regressions.

platform/x86: hp-wmi: Add Omen 16-wf0xxx fan and thermal support

2026-02-23T14:28:06Z

The HP Omen 16-wf0xxx (board ID: 8BAB) has the same WMI interface as other Victus S boards, but requires quirks for correctly switching thermal profile (similar to HP Omen 16-wf1xxx, board ID: 8C78). Add the DMI board name to victus_s_thermal_profile_boards[] table and map it to omen_v1_thermal_params. Testing on HP Omen 16-wf0xxx confirmed that platform profile is registered successfully and fan RPMs are readable and controllable.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
