From be8802a9414e85ba07ae257fccadd245fcf7c7b6 Mon Sep 17 00:00:00 2001 From: Ilija Hadzic Date: Thu, 24 Mar 2011 13:24:28 -0400 Subject: [PATCH] libdrm: (revised) vblank wait on crtc > 1 Hi Alex, Enclosed is a revised version of the patch sent on Mar 18, against the master branch of the drm userspace (i.e. libdrm). Details summarised in this thread: http://lists.freedesktop.org/archives/dri-devel/2011-March/009499.html This patch reconciles libdrm with the the kernel change that Dave pushed this morning. It *supersedes* the previously sent patch (i.e. apply it to the master branch as it exists at the time of this writing, not as an incremental patch to the one sent previously).
