Summary|GPU hang on kernel 3.13.0 |[ivb] hang on pageflip
--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
It appears to have hung trying to execute a pageflip.
0x00007eb0: 0x0a000001: MI_DISPLAY_BUFFER_INFO
0x00007eb4: 0x00001e01: dword 1
0x00007eb8: 0x06446000: dword 2
0x00007ebc: 0x00000000: MI_NOOP
which looks consistent with
fence[14] = 6c3d03b06446001
valid, x-tiled, pitch: 7680, start: 0x06446000, size: 8355840
and
Pinned [33]:
...
06446000 8355840 41 00 0 0 P X dirty uncached (name: 49) (fence: 14)
Can you please attach the full dmesg leading to the hang? Does this happen
frequently or was this a one-off event?
