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

2016-07-29T18:36:52Z

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

2016-07-07T19:02:06Z

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()

We don't need to use &amdgpu_crtc->base there as crtc is available in the function. Signed-off-by: Gustavo Padovan Reviewed-by: Michel Dänzer Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1465308482-15104-9-git-send-email-gustavo@padovan.org

drm: Remove unused drm_device from drm_gem_object_lookup()

2016-05-17T06:47:30Z

drm_gem_object_lookup() has never required the drm_device for its file local translation of the user handle to the GEM object. Let's remove the unused parameter and save some space.

drm/amdgpu: Support DRM_MODE_PAGE_FLIP_ASYNC (v2)

2016-05-11T16:31:25Z

When this flag is set, we program the hardware to execute the flip during horizontal blank (i.e. for the next scanline) instead of during vertical blank (i.e. for the next frame).

drm/amd: Mark some tables as const

2016-05-05T00:20:00Z

This patch marks some compile-time constant tables 'const'. The tables marked in this patch are the low hanging fruit where little other changes were necesary to avoid casting away constness etc. Also mark some tables that are private to a file as static.

drm/amdgpu: Set PFLIP_SUBMITTED for crtc after address update

2016-05-05T00:19:07Z

Also add some pflip debug prints. This change allows us to wait on pflip status until the new surface address is actually submitted to the register.

This moves the flip before status update which makes sense for the non-DAL code pathes as well.
