Subject: i965: Disable HiZ on Broadwell for now.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=01ae16a0e7d95f408016ff5b07bc647ad5608841;p=mesa.git

i965: Disable HiZ on Broadwell for now.

HiZ is difficult to implement, and while it's essential for performance,
we don't need it right away for purposes of hardware enabling.
