I encountered a page-fault-of-doom, due to i915_gem_fault() spinning on a flush. i915_gem_reset() should fixup the buffers to prevent that. However, I thought the EIO checks served as nice documentation along paths that simply did not care why the GPU was no longer accessing the buffer only that it wasn't. -Chris -- Chris Wilson, Intel Open Source Technology Centre
