From: Kristian Høgsberg Date: Fri, 3 Aug 2012 15:30:18 +0000 (-0400) Subject: compositor: Accumulate damage per plane X-Git-Tag: submit/trunk/20120814.155504~99 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65a11e1039e7ea429ff26bdd0058bdf0efd1df2d;p=profile%2Fivi%2Fweston.git compositor: Accumulate damage per plane When we analyze and accumulate damage prior to repainting, we need to accumulate damage per plane, so that whatever damage a surface contributes is accumulated in the plane that it's assigned to. Before, we would always accumulate damge in the primary plane, which caused repaints in the primary plane whenever a surface in a sprite or framebuffer was damaged. Eliminating this repaint is a big win for cases where we pageflip to a client surface or use a sprite overlay. This also prepares for fixing the missing cursor updates, since we now track damage to the cursor surface in a dedicated sprite plane. --- diff --git a/src/compositor-drm.c b/src/compositor-drm.c index 8616527..afed9fe 100644 --- a/src/compositor-drm.c +++ b/src/compositor-drm.c @@ -65,12 +65,6 @@ struct drm_configured_output { struct wl_list link;
