drm/fence: add fence timeline to drm_crtc
Create one timeline context for each CRTC to be able to handle out-fences and signal them. It adds a few members to struct drm_crtc: fence_context, where we store the context we get from fence_context_alloc(), the fence seqno and the fence lock, that we pass in fence_init() to be used by the fence. v2: Comment by Daniel Stone: - add BUG_ON() to fence_to_crtc() macro v3: Comment by Ville Syrjälä - Use more meaningful name as crtc timeline name v4: Comments by Brian Starkey - Use even more meaninful name for the crtc timeline - add doc for timeline_name Comment by Daniel Vetter - use in-line style for comments - rebase after fence -> dma_fence rename v5: Comment by Daniel Vetter - Add doc for drm_crtc_fence_ops v6: Comment by Chris Wilson - Move fence_to_crtc to drm_crtc.c - Move export of drm_crtc_fence_ops to drm_crtc_internal.h - rebase against latest drm-misc Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> (v5) Reviewed-by: Sean Paul <seanpaul@chromium.org> (v5) Tested-by: Robert Foss <robert.foss@collabora.com> (v5) Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1479220628-10204-1-git-send-email-gustavo@padovan.org
