Subject: iris: Don't whack SO dirty bits when finishing a BLORP op
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3bcb1a7fcd09e60dcd134e925e7a139e0e9691f3;p=mesa.git

iris: Don't whack SO dirty bits when finishing a BLORP op

Re-emitting 3DSTATE_SO_BUFFERS can be hazardous, as it could zero
offsets.  Plus, it's just not necessary - BLORP doesn't change these.
