This is not the correct parameter. The parameter for guc log verbosity control is i915.guc_log_level. Valid values are -1,0,1,2,3. I see log content immediately after boot with i915.guc_log_level=1. Note that GuC submission *must* be enabled for logging to be enabled. GuC loading alone is not enough. Also please cat the i915.guc_log_level after boot. There may be conditions where driver will override the value back to -1 (disabled).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
