Subject: iris: BIG OL' HACK for UBO updates
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f3dd70182d0da93812efcc79a9e6854aceb594f5;p=mesa.git

iris: BIG OL' HACK for UBO updates

We need to re-push data when UBO changes.  This will need to be replaced
with a usage history based flushing system later.
