So, batches should be executed instantaneous, much less than 100ms. Actually I would like to point out 2 issues here: 1. Media fails on the key use case 2. i915 driver hides GPU hang and does not provide a way to get the error dump The first one is critical for TGL program. The second one is critical in a longer term - how we are supposed to debug hangs? I strongly suggest to either change/fix the behavior and allow dumps or introduce special i915 module parameter to again allow dumps. In case of a parameter I would suggest to print message into dmesg log to suggest user rerun workload with this parameter and capture dump.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
