Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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

drm/amdgpu: Do not implement mode_set_base_atomic callback

2025-12-02T08:20:22+00:00

Remove all implementations of the CRTC helper mode_set_base_atomic from amdgpu. It pretends to provide mode setting for kdb debugging, but has been broken for some time. Kdb output has been supported only for non-atomic mode setting since commit 9c79e0b1d096 ("drm/fb-helper: Give up on kgdb for atomic drivers") from 2017. While amdgpu provides non-atomic mode setting for some devices, kdb assumes that the GEM buffer object is at a fixed location in video memory. This has not been the case since commit 087451f372bf ("drm/amdgpu: use generic fb helpers instead of setting up AMD own's.") from 2021. Fbdev-ttm helpers use a shadow buffer with a movable GEM buffer object. Triggering kdb does not update the display. Hence remove the whole kdb support from amdgpu.

drm/amd/pm: Remove wm_low and wm_high fields from amdgpu_crtc (v2)

2025-09-02T19:57:01+00:00

These fields were only used by si_dpm and are not necessary anymore. They also may have been incorrect because: - wm_high was set to the LOW_WATERMARK field of watermark A. - wm_low was not set on DCE 6 and was always zero.

drm/amdgpu: use "irq" in place of "interrupt" in DCE6/8 as in DCE10/11

2025-04-08T20:48:13+00:00

"interrupt" becomes "irq" in: dce_vX_0_set_hpd_interrupt_state() dce_vX_0_set_crtc_interrupt_state() dce_vX_0_set_pageflip_interrupt_state() It is easier when going through the code to just change the DCE number in the functions' name to find and compare them across DCE versions. Also, it standardizes function mapping inside a given structure where .set and .process are both set to functions with a "_irq" suffix. Signed-off-by: Alexandre Demers Signed-off-by: Alex Deucher
