Subject: anv/cmd_buffer: Emit gen9 style SF state for CHV
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=89ec36f221099cf47ade0b90d09c7731460ab381;p=mesa.git

anv/cmd_buffer: Emit gen9 style SF state for CHV

The state for line width changes on Cherryview to use the GEN9 bits (for extra
precision).
