Subject: [PATCH 5/6] drm/amdgpu/si: reduce dma ring size
Date: Fri, 20 May 2016 17:50:38 -0400 [thread overview]
Message-ID: <1463781039-722-5-git-send-email-alexander.deucher@amd.com> (raw)
In-Reply-To: <1463781039-722-1-git-send-email-alexander.deucher@amd.com>
This was already done for other asics. We don't need
a very big ring with the scheduler.
