Further investigation will be deferred > until after upcoming update to guc version and only if issue seen with > i915.enable_guc=2 (no submission via GuC) which is support model for Gen9. Of course it won't be seen with enable_guc=2, the issue is that preemption is broken via the guc! I take it we should just remove the unstable unsupported feature from the guc submission path?</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>
