Subject: GEM: Remove already-disabled PIPE_CONTROL command.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ead798eb103e4cfe801704bc15eb4fe8df078fa8;p=mesa.git

GEM: Remove already-disabled PIPE_CONTROL command.

This existed to get the icache flushed.  However, GEM handles this for us
now for sure, and we had disabled it prematurely anyway.
