[Intel-gfx] [PATCH v2] drm/i915: Taint (TAINT_DIE) the kernel if the GPU reset fails

2017-11-29 Thread Chris Wilson
History tells us that if we cannot reset the GPU now, we never will. This then impacts everything that is run subsequently. On failing the reset, we mark the driver as wedged, trying to prevent further execution on the GPU, forcing userspace to fallback to using the CPU to update its framebuffers
