Subject: i965: Be a bit more conservative about certain resolves
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0607ca42da5fdb79b64445e34c642925e94354de;p=mesa.git

i965: Be a bit more conservative about certain resolves

There are several places where we were resolving the entire miptree
when we really only needed to resolve a single slice.  Let's avoid the
unneeded resolving.
