An orthogonal (but losely related) question: Is PXP the only subsystem that has
the unique problem of: Uses a delayed worker to complete all dependencies for init..
but they take so long that by the time compositors-mesa-init comes up, creation
of PXP context blocks too long and may still likely failing and incorrectly
assuming PXP is not supported. (when we don't have a GET_PARAM for it).
I believe HuC has a similiar issue - but doesnt reflect in the UAPI but rather the cmd buffers.
We don't have other subsystems that have this problem? (dependency on other startups?)
