Subject: [PATCH] drm/radeon: properly set vm fragment size for TN/RL
Date: Fri, 30 Jan 2015 09:54:04 -0500	[thread overview]
Message-ID: <1422629644-4766-2-git-send-email-alexander.deucher@amd.com> (raw)
In-Reply-To: <1422629644-4766-1-git-send-email-alexander.deucher@amd.com>

Should be the same as cayman.  We don't use VM by default
on NI parts so this isn't critical.
