This patch simply changes the default value of "enable_guc_submission" from 0 (never) to -1 (auto). This means that GuC submission will be used if the platform has a GuC, the GuC supports the request submission protocol, and any required GuC firmwware was successfully loaded. If any of these conditions are not met, the driver will fall back to using execlist mode.
