[PATCH v2 4/7] drm/i915/guc: Refactoring preparation of the GUC_CTL_LOG_PARAMS parameter

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

 



At the moment, the preparation of GUC_CTL_LOG_PARAMS is disordered.
Additionally, in struct intel_guc_log we have an unnecessary field
'flags' which we use only to assign value to GuC parameter.
Lets move all GUC_CTL_LOG_PARAMS related operations to one place,
and lets remove field 'flags' from struct intel_guc_log.
