Hi, Apologies for this unfriendly series, in the end squashing everything into a single commit didn't look too good. We went through quite a few iterations to figure all the instability issues on Gen8+. This has finally reached a state where you can run the tests on a machine with other applications using the GPU in parallel. This gives us confidence that we now have a pretty good understanding of how the filtering of reports should be done as well as things that might affect periodic report timings. Most of Rob's patches are already reviewed or co-authored. I'm not really expecting a someone to thoroughly review all of these changes as it takes a fair amount of time to get into all of the fiddly details, but if someone could look at the end result and quickly read through to check there isn't something terribly wrong, that would be helpful.
