From: Axel Davy Date: Mon, 4 Jan 2016 15:15:18 +0000 (+0100) Subject: st/nine: Use fast clears more often for MRTs X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ee31f0fed4bd97e3c9a0c4547ad908d55607f532;p=mesa.git st/nine: Use fast clears more often for MRTs This enables to use fast clears in the following case: pixel shader renders to 1 RT 4 RT bound clear new pixel shader bound that renders to 4 RTs Previously the fast clear path wouldn't be hit, because when trying the fast clear path, the framebuffer state would be configured for 1 RT, instead of 4.
