From: Bas Nieuwenhuizen Date: Sat, 3 Aug 2019 22:48:05 +0000 (+0200) Subject: radv: Put wave size in shader options/info. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=035406ecf78a07e2b05fd2bec29725f83187828c;p=mesa.git radv: Put wave size in shader options/info. Instead of having the three values everywhere. This is also more future proof if we want the driver to make those decisions eventually.
