From ec301497b87e915924240173ac2854d835446cc6 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 26 Apr 2017 00:36:12 +0200 Subject: [PATCH] radeonsi: use unsynchronized transfers for shader binary uploads MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Because the buffer is new, it can't be referenced by any CS. This can save few CPU cycles by skipping the whole PIPE_TRANSFER_UNSYNCHRONIZED if in amdgpu_bo_map().
