drm/amdgpu: Delete soft reset code from legacy display driver

2026-07-01T15:11:48+00:00

This was basically dead code, not used or called from anywhere. Now that DC is the default display driver for all ASICs, it is unlikely that anyone wants to develop this further. Display hang related work should be focused on DC. Reviewed-by: Alex Deucher Signed-off-by: Timur Kristóf Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu/amdgpu_connectors: use struct drm_edid instead of struct edid

2026-03-06T21:32:27+00:00

Some amdgpu code is still using deprecated edid functions. Switch to the newer functions and update the amdgpu_connector struct's edid type to the drm_edid type. At the same time, use the raw EDID when we need to for speaker allocations and for determining if the input is digital. Signed-off-by: Joshua Peisach Signed-off-by: Alex Deucher

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
