[Intel-gfx] [PATCH 00/47] GuC submission support

Fri Oct 22 09:35:04 UTC 2021

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
