From: Alex Deucher Date: Tue, 29 Jan 2013 19:10:56 +0000 (-0500) Subject: drm/radeon: use callbacks for ring pointer handling (v3) X-Git-Tag: v3.11-rc1~65^2~60^2~117 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f93bdefe6269067afc85688d45c646cde350e0d8;p=karo-tx-linux.git drm/radeon: use callbacks for ring pointer handling (v3) Add callbacks to the radeon_asic struct to handle rptr/wptr fetchs and wptr updates. We currently use one version for all rings, but this allows us to override with a ring specific versions. Needed for compute rings on CIK. v2: udpate as per Christian's comments v3: fix some rebase cruft Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/radeon/radeon.h
