Disable acceleration if we detect a hardware error.
This is wildly optimistic, but it should work in a surprising number of error situations and some output in those cases will be hopefully be better than none... If we submit a batchbuffer and the kernel reports the GPU is hung (which will be caused by an earlier execbuffer, and so the kernel should have had enough time to determine whether or not it could reset the GPU) then disable any further attempt to accelerate gfx and force fallbacks to map the buffers and use the CPU. We cannot normally map any more buffers if the GPU is hung, so only those already mapped prior to the hang can be written to, or those allocated in system memory. However, we can expect that the framebuffer is already mapped, and so have a reasonable expectation to continue to see the display update. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
