From: Michał Winiarski <[email protected]> The information about platform/driver/user view of GuC firmware usage currently requires user to either go through kernel log or parse the combination of "enable_guc" modparam and various debugfs entries. Let's keep things simple and add a "supported/used/wanted" matrix (already used internally by i915) in guc_info debugfs.
