Subject: [PATCH v5 07/14] media: mediatek: vcodec: support 36bit iova address
Date: Wed, 3 Jun 2026 16:40:37 +0800 [thread overview]
Message-ID: <20260603084045.17488-8-kyrie.wu@mediatek.com> (raw)
In-Reply-To: <20260603084045.17488-1-kyrie.wu@mediatek.com>
From: Yunfei Dong <yunfei.dong@mediatek•com>
Need to set dma mask to support 36bit iova address for decoder
hardware can use 36bit address to decode for mt8196.
