It looks like Maarten now merged Matt's series to IGT.

There is a series on IGT trybot with pending work to have some igt tests 
support relocations,

https://patchwork.freedesktop.org/series/92043/

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.

Also the following series:

https://patchwork.freedesktop.org/series/93455/

tries a bit harder to get some more tests running, squashing the above 
series on top of latest IGT.

Thanks,
