Subject: anv: Drop URB entry output read handling in 3DSTATE_XS.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=49d3c004f17bcbff0a4822b49268fcde412b38e2;p=mesa.git

anv: Drop URB entry output read handling in 3DSTATE_XS.

Commit 566a0c43f0b9fbf5106161471dd5061c7275f761 started setting the
3DSTATE_SBE bit to override these values with the one calculated there.

So, they're dead.  Stop setting them.
