<pre>if i keep using mesa git, xorg git, radeon git, drm git, kernel 3.17 and above
AND intel git1406031225.081488, everything works fine:
- VAAPI works (encoding/decoding)
easily tested by using:
mpv --vo=vaapi --hwdec=vaapi file.mp4 (low cpu usage)
mpv --vo=opengl --hwdec=vaapi file.mp4 (even lower cpu usage)
- OpenGL works fine
- KWin compositing works fine, same for Unity
- Chrome HW accel works fine
NOW, if i upgrade the i965 driver to any commit past git1406031225.081488,all
hell breaks loose:
- VAAPI crashes the GPU
- Chrome hangs with segfault, GPU hangs
- KWIN compositing works
- OpenGL works for a few minutes, then the GPU crashes
i have a DELL LATITUDE 3540 (HD4400, RADEON HD8850m) hybrid</pre>
