Subject: [PATCH v10 04/10] gpu: nova-core: falcon: remove FalconFirmware's dependency on FalconDmaLoadable
Date: Sun, 01 Mar 2026 23:03:47 +0900	[thread overview]
Message-ID: <20260301-turing_prep-v10-4-dde5ee437c60@nvidia.com> (raw)
In-Reply-To: <20260301-turing_prep-v10-0-dde5ee437c60@nvidia.com>

Not all firmware is necessarily loaded by DMA. Remove the requirement
for `FalconFirmware` to implement `FalconDmaLoadable`, and adapt
`Falcon`'s methods constraints accordingly.
