From b409524fef1b02c717b4cc1fef70d5710781f824 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sun, 6 Sep 2015 15:41:35 +0200 Subject: gallium/radeon: handle PIPE_TRANSFER_FLUSH_EXPLICIT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Basically, do the same thing as for buffer_unmap, but use the explicit range instead. It's for apps which want to map a whole buffer and mark touched ranges explicitly.
