Arun Siluvery 6b332fa20f drm/i915/guc: reset GuC and retry on firmware load failure ... Due to timing issues in the HW, some of the status bits required for GuC authentication occasionally don't get set; when that happens, the GuC cannot be initialized and we will be left with a wedged GPU. The W/A suggested is to perform a soft reset of the GuC and attempt to reload the F/W again for few times before giving up. As the failure is dependent on timing, tests performed by triggering manual full gpu reset (i915_wedged) showed that we could sometimes hit this after several thousand iterations, but sometimes tests ran even longer without any issues. Reset and reload mechanism proved helpful when we indeed hit f/w load failure, so it is better to include this to improve driver stability.
