Subject: [PATCH 3/7] drm/amdgpu: use allowed_domains for exported DMA-bufs
Date: Wed, 19 Feb 2020 13:59:06 +0100 [thread overview]
Message-ID: <20200219125910.89147-3-christian.koenig@amd.com> (raw)
In-Reply-To: <20200219125910.89147-1-christian.koenig@amd.com>
Avoid that we ping/pong the buffers when we stop to pin DMA-buf
exports by using the allowed domains for exported buffers.
