From: Jason Ekstrand Date: Thu, 22 Jun 2017 03:19:54 +0000 (-0700) Subject: i965/miptree: Rework prepare/finish_render to be in terms of aux_usage X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=baa9e059659ed834d084ee4faf6271a8dd508494;p=mesa.git i965/miptree: Rework prepare/finish_render to be in terms of aux_usage We keep the old and possibly broken method of determining aux usage intact for now. Therefore, the only functional change here is that we may call finish_render a bit more accurately.
