From: Marek Olšák Date: Mon, 15 May 2017 21:45:57 +0000 (+0200) Subject: radeonsi: do only 1 big CE dump at end of IBs and one reload in the preamble X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edb59ef2dc8085631e14153d2b7838b63961f2f0;p=mesa.git radeonsi: do only 1 big CE dump at end of IBs and one reload in the preamble A later commit will only upload descriptors used by shaders, so we won't do full dumps anymore, so the only way to have a complete mirror of CE RAM in memory is to do a separate dump after the last draw call.
