Subject: nv20: disable depth writes in hw init
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=767f72c1087ff253288c3e62a4f0d8b4d8257c9c;p=mesa.git

nv20: disable depth writes in hw init

Probably not necessary, but just in case. Depth registers point to the
color buffer, when there is no depth buffer.
