From 0c88a02ef6b7e29a811f0d56367cc2268c4ef433 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 2 Mar 2011 20:07:31 -0500 Subject: drm/radeon/kms: add support for CP setup on cayman asics Cayman asics have 3 ring buffers: ring 0 supports both gfx and compute rings 1 and 2 are compute only At the moment we only support ring 0.
