Subject: nvc0: disable tessellation on maxwell
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d3e23f1ff915c01541f8df375b50b93b3da565a8;p=mesa.git

nvc0: disable tessellation on maxwell

The address calculations are all different (e.g. see GP), there appear
to be sync's in programs, and probably a bunch of other differences.
Just disable it for now.
