We suspect the DG1 in CI is an early stepping and we may be missing workarounds. Have a possible fix, just need to try it out. We also might just want to replace the DG1 part in CI with a newer stepping so we don't have to upstream WAs for non-shipping parts. > One of the tests that have WIP fixes is gem_exec_whisper, and that > particular test has historically shown occasional hangs with GuC submission > on DG1 so it would be very desirable if we could make that test in > particular work (I haven't verified that that's the case) reliably. > I just ran gem_exec_whisper on DG1, with GuC submission, and kernel hacked to allow relocs. It passed for me. Only 1 run though so it is possible there are still intermittent issues. We really need to get CI up and running ASAP on all platforms where GuC submission is POR. Perhaps on all gen11+ platforms as well because GuC submission is supported and the more coverage we can get, the better. > Also the following series: > > https://patchwork.freedesktop.org/series/93455/ I'll check this series out too.
