Hi,

Bumping this again - it's been quite a while, what became of that KFD
bugfix and the userqueue stuff? It'd be nice to finally make progress
here, whether it's using the user queue interface you worked on or a
re-spin of this. Maybe it's possible to split this off from the rest of
the userqueue stuff and merge it beforehand if you're reasonably certain
about how the uapi should look? Let me know.
That is merged into amd-staging-drm-next for quite a while now, but we
only defined the interface and dropped all optimizations to initially
get it upstream.
@Alex IIRC we pushed the KFD part upstream already, but the userqueue
part is still waiting for the final firmware release, right?
Correct.
Right. Any rough timeline for when we can expect that firmware to release?
Thanks,
