[PATCH] drm/i915/guc: Don't store runtime GuC log level in modparam

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Piotr Piórkowski <piotr.piorkowski@xxxxxxxxx>

Currently we are using modparam as placeholder for GuC log level.
Stop doing this and keep runtime GuC level in intel_guc_log struct.
