6.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alex Deucher <alexander.deucher@xxxxxxx> commit 4de34b04783628f14614badb0a1aa67ce3fcef5d upstream. This adds allocation latency, but aligns better with user expectations. The latency should improve with the drm buddy clearing patches that Arun has been working on. In addition this fixes the high CPU spikes seen when doing wipe on release. v2: always set AMDGPU_GEM_CREATE_VRAM_CLEARED (Christian) Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3528 Fixes: a68c7eaa7a8f ("drm/amdgpu: Enable clear page functionality") Acked-by: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@xxxxxxx> Reviewed-by: Michel Dänzer <mdaenzer@xxxxxxxxxx> (v1) Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@xxxxxxx> Cc: Christian König <christian.koenig@xxxxxxx> (cherry picked from commit 6c0a7c3c693ac84f8b50269a9088af8f37446863) Cc: stable@xxxxxxxxxxxxxxx # 6.10.x Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c | 3 +++ 1 file changed, 3 insertions(+) --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c @@ -347,6 +347,9 @@ int amdgpu_gem_create_ioctl(struct drm_d return -EINVAL; } + /* always clear VRAM */ + flags |= AMDGPU_GEM_CREATE_VRAM_CLEARED; + /* create a gem object to contain this object in */ if (args->in.domains & (AMDGPU_GEM_DOMAIN_GDS | AMDGPU_GEM_DOMAIN_GWS | AMDGPU_GEM_DOMAIN_OA)) {
