Feel free to do some benchmarking if you want.
The question is why this code at the end of the function didn't set one of =
the
flush flags:
r600_flag_resource_cache_flush(rctx, dst);
Constants are usually read with the shader cache and indirect addressing of=
the
constants goes through the vertex cache. Also some chips don't have the ver=
tex
cache, so they have to use the texture cache instead. That's why both VERTEX
and CONST work for some chips in this situation. The purpose of the flags i=
s to
express what type of buffer was changed. The flushing code will then figure=
out
which cache should be flushed.
