Yes I'm not sure how we should do indirects, the si docs mention
that their compiler does all or nothing (at least it did when the docs were
written, look for Flat Table Mode).
My current thinking is still make 0,1 point to a buffer of global ptrs,
so s[0:1] point to a buffer with ->
0, 1 spill ring uint64_t ptr
2,3,4,5 ring descriptor[0]
6,7,8,9 ring descriptor[1]
where the ring descriptors are the es/gs/vs/tess rings.
Then I'd probably leave indirects for the descriptor set cases
where we have more than 1 set bound (AMD recommend using
a single set), and leave vertex buffers on their own as well.
I suppose it might be worth optimising push constants but it could
be very hit and miss what would be optimal for what application I'd say.
I'll do some more testing on this series but I've seen no regressions with yet,
and my initial shader-db shows some improvements (not that I can trust my
shader-db is doing anything sane yet).
