Chris Wilson 9df30794f6 drm/i915: Record batch buffer following GPU error ... In order to improve our diagnostic capabilities following a GPU hang and subsequent reset, we need to record the batch buffer that triggered the error. We assume that the current batch buffer, plus a few details about what else is on the active list, will be sufficient -- at the very least an improvement over nothing. The extra information is stored in /debug/dri/.../i915_error_state following an error, and may be decoded using intel_gpu_tools/tools/intel_error_decode. v2: Avoid excessive work under spinlocks. v3: Include ringbuffer for later analysis. v4: Use kunmap correctly and record more buffer state. v5: Search ringbuffer for current batch buffer v6: Use a work fn for the impossible IRQ error case. v7: Avoid non-atomic paths whilst in IRQ context.
