Snapshot 2.99.917 (2014-12-21) ============================== 3 months drifted by whilst I looked elsewhere for bugs.. The highlight of bugs fixed here are a couple of workarounds required for Broadwell and making sure that the rasterisation code is symmetric under inversions. However, as a couple of crashers slipped through into 2.99.916 (though not actual regressions in 2.99.916 per se) and 3 months have passed, we should make one more snapshot before an imminent release. * Beware of recomputing the clear hint in the middle of MI recursion https://bugs.freedesktop.org/show_bug.cgi?id=77074 * Fix crash from rendering an empty Glyph string under PRIME as the secondary driver * Restore application of default monitor options to the first output, a regression in 2.99.915 and the MST support https://bugs.gentoo.org/show_bug.cgi?id=522500 * Finally fix ZaphodHeads blocking on waiting for flip completion events. Before kernel 3.19, O_NONBLOCK support is broken and so we must avoid reading if we are not expecting an event. * Backwards compatibilty fix for fake triple buffering with PRIME and Xorg-1.15 https://bugs.freedesktop.org/show_bug.cgi?id=85144#c12 * Fix a rendering issue with output rotation and software fallbacks. https://bugs.freedesktop.org/show_bug.cgi?id=84653 * Enable MST discovery even without udev support https://bugs.freedesktop.org/show_bug.cgi?id=84718 * Fix TearFree operation after the GPU is wedged https://bugs.freedesktop.org/show_bug.cgi?id=85058 * Fix projective sampling on gen6+. * Fix rendering and corruption with gen8. https://bugs.freedesktop.org/show_bug.cgi?id=84958 https://bugs.freedesktop.org/show_bug.cgi?id=83207 https://bugs.freedesktop.org/show_bug.cgi?id=79053 https://bugs.freedesktop.org/show_bug.cgi?id=81583 * Fix crash when using Xinerama. https://bugs.freedesktop.org/show_bug.cgi?id=87207 * Fix
