Subject: i965: Always set MaxViewports and related limits
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=90c51ccf82e04d06aa63aea49121165b7f2e8991;p=mesa.git

i965: Always set MaxViewports and related limits

Since 9d6ca7c3, there should be no performance hit for having
MaxViewports > 1.  Always set this context state.  This eliminates the
need to update this conditional as we add support for OES_viewport_array
on older GPUs.
