Subject: [PATCH 2/2] drm/amdgpu: use GTT for uvd_get_create/destory_msg
Date: Mon, 21 Dec 2020 17:05:11 +0800 [thread overview]
Message-ID: <87pn33y1fc.wl-chenli@uniontech.com> (raw)
In-Reply-To: <87r1njy1s7.wl-chenli@uniontech.com>
On modern gpus, GTT (system memory) works as well here, and this may
also be a workaround for platforms which cannot map vram correctly.
