From 1f6b92b47652e7f48f03ef6a4228a19537022d23 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 27 Dec 2018 14:26:49 +1000 Subject: [PATCH] gallium: use put image shm2 path (v2) This fixes the drisw paths to use the new shm2 interface, so that we don't trigger the X server overflow checks when the x offset is non-zero. This just hides the versioning in drisw, and either passes the src_x or adds the offset fixup for the fallback path.
