Subject: [PATCH v2 3/7] gpu: nova-core: firmware: fwsec: use dma::Coherent
Date: Fri, 27 Mar 2026 00:22:09 +0900 [thread overview]
Message-ID: <20260327-b4-nova-dma-removal-v2-3-616e1d0b5cb3@nvidia.com> (raw)
In-Reply-To: <20260327-b4-nova-dma-removal-v2-0-616e1d0b5cb3@nvidia.com>
Replace the nova-core local `DmaObject` with a `Coherent` that can
fulfill the same role.
