From: Grazvydas Ignotas Date: Tue, 22 Dec 2015 02:12:07 +0000 (+0200) Subject: r600: fix constant buffer size programming X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=da0e216e069bd064199ed04b52de6fb23d810806;p=mesa.git r600: fix constant buffer size programming When buffer size is less than 16, zero ends up being programmed as size, which prevents the hardware from fetching the correct values. Fix it by combining shift and align so that the value is always rounded up.
