drm/amdgpu: fix ref count leak in amdgpu_display_crtc_set_config

2020-09-03T09:21:16+00:00

[ Upstream commit e008fa6fb41544b63973a529b704ef342f47cc65 ] in amdgpu_display_crtc_set_config, the call to pm_runtime_get_sync increments the counter even in case of failure, leading to incorrect ref count. In case of failure, decrement the ref count before returning. Signed-off-by: Navid Emamdoost Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amdgpu: Fail fb creation from imported dma-bufs. (v2)

2018-03-22T08:17:49+00:00

[ Upstream commit 1769152ac64b0b07583f696b621624df2ca4c840 ] Any use of the framebuffer will migrate it to VRAM, which is not sensible for an imported dma-buf. v2: Use DRM_DEBUG_KMS to prevent userspace accidentally spamming dmesg.

drm/amdgpu: Provide page_flip_target hook

2016-08-10T18:28:06+00:00

Now we can program a flip during a vertical blank period, if it's the one targeted by the flip (or a later one). This allows simplifying amdgpu_flip_work_func considerably. agd: update dce_virtual.c as well. Acked-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amdgpu: Delete an unnecessary check before drm_gem_object_unreference_unlocked()

2016-07-29T18:36:52+00:00

The drm_gem_object_unreference_unlocked() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Reviewed-by: Christian König Signed-off-by: Markus Elfring Signed-off-by: Alex Deucher

drm/amdgpu: Unpin BO if we can't get fences in amdgpu_crtc_page_flip

2016-07-07T19:02:06+00:00

If reservation_object_get_fences_rcu failed, we'd previously go directly to the cleanup label, so we'd leave the BO pinned. While we're at it, remove two amdgpu_bo_unreserve calls in favour of two new labels. Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amdgpu: use crtc directly in drm_crtc_vblank_put()
