Hi Matt & John,
Can you please queue patches with the right Fixes: references to convert all the GuC tracepoints to be protected by the LOW_LEVEL_TRACEPOINTS protection for now. Please do so before next Wednesday so we get it queued in drm-intel-next-fixes.
There's the orthogonal track to discuss what would be the stable set of tracepoints we could expose. However, before that discussion is closed, let's keep a rather strict line to avoid potential maintenance burned.
We can then relax in the future as needed.
Regards, Joonas

As discussed in [1], [2] we are enabling GuC submission support in the i915. This is a subset of the patches in step 5 described in [1], basically it is absolute to enable CI with GuC submission on gen11+ platforms.
This series itself will likely be broken down into smaller patch sets to merge. Likely into CTBs changes, basic submission, virtual engines, and resets.
A following series will address the missing patches remaining from [1].
Locally tested on TGL machine and basic tests seem to be passing.
