 Two new module parameters: enable_guc_submission which will turn
 on submission of batchbuffers via the GuC (when implemented), and
 guc_log_level which controls the level of debugging logged by the
 GuC and captured by the host.

[Intel-gfx] [PATCH 02/13 v4] drm/i915: Add GuC-related module parameters

2015-07-09 Thread Dave Gordon 
From: Alex Dai yu@intel.com

Two new module parameters: enable_guc_submission which will turn
on submission of batchbuffers via the GuC (when implemented), and
guc_log_level which controls the level of debugging logged by the
GuC and captured by the host.
