2025-12-10drm/amdkfd: disable shader message vgpr deallocation on gc 12.1Jonathan Kim
Shader messages to deallocate VGPRs prior to shader end can prevent the trap handler from saving context, making debugging and core dumps unreliable.

2025-12-10drm/amdgpu/acpi: Reduce amdgpu_acpi_detect stack usageSrinivasan Shanmugam
amdgpu_acpi_detect() calls some helper functions it calls have large local structures. When the compiler inlines these helpers, their local data adds to the amdgpu_acpi_detect() stack frame. Mark the helpers with noinline_for_stack: - amdgpu_atif_verify_interface() - amdgpu_atif_get_notification_params() - amdgpu_atif_query_backlight_caps() - amdgpu_atcs_verify_interface() - amdgpu_acpi_enumerate_xcc() This keeps the large temporary objects inside the helper’s own stack frame instead of being inlined into the caller, preventing the caller from growing beyond the stack limit. Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c:1403:6: warning: stack frame size (1688) exceeds limit (1024) in 'amdgpu_acpi_detect' [-Wframe-larger-than] Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-12-08drm/amdgpu: introduce amdgpu_ttm_buffer_entityPierre-Eric Pelloux-Prayer
No functional change for now, but this struct will have more fields added in the next commit. This change would introduce synchronisation issue, because dependencies between successive jobs are not taken care of properly. For instance, amdgpu_ttm_clear_buffer uses amdgpu_ttm_map_buffer then amdgpu_ttm_fill_mem which should use different entities (default_entity then move/clear entity). To prevent failures for this commit, we limit ourselves to 2 entities: default_entity (which replaces high_pr usages) and clear_entity (which replaces low_pr usages). The next commits will deal with these dependencies correctly, and then we'll be able to use move_entity. --- v2: renamed amdgpu_ttm_buffer_entity v4: don't use move_entity in ttm yet --- Signed-off-by: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> (v3) Acked-by: Felix Kuehling <felix.kuehling@amd.com> (v3) Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
