From 6d6003c4b613c93973e4e870d83f4bed2ad9ac34 Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Tue, 15 Nov 2016 23:37:08 +0900 Subject: drm/fence: add fence timeline to drm_crtc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Reviewed-by: Daniel Vetter (v5) Reviewed-by: Sean Paul (v5) Tested-by: Robert Foss (v5) Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1479220628-10204-1-git-send-email-gustavo@padovan.org --- drivers/gpu/drm/drm_crtc_internal.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/gpu/drm/drm_crtc_internal.h') diff --git a/drivers/gpu/drm/drm_crtc_internal.h b/drivers/gpu/drm/drm_crtc_internal.h index f78d5aaf7e91..33b17d0b127e 100644 --- a/drivers/gpu/drm/drm_crtc_internal.h +++ b/drivers/gpu/drm/drm_crtc_internal.h @@ -43,6 +43,8 @@ int drm_crtc_check_viewport(const struct drm_crtc *crtc, int drm_crtc_register_all(struct drm_device *dev); void drm_crtc_unregister_all(struct drm_device *dev); +extern const struct dma_fence_ops drm_crtc_fence_ops; + /* IOCTLs */ int drm_mode_getcrtc(struct drm_device *dev, void *data, struct drm_file *file_priv); -- cgit v1.2.3-59-g8ed1b
