From 7bd4d7be5c8c35a401b1589201e5d43a64d3f05b Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Thu, 19 Nov 2009 10:50:22 -0800 Subject: drm: use page flip event to signal flip completion MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We don't actually know which frame number the flip will complete on, so userspace needs a specific flip notification to tell it when the last flip completed.
