Subject: [PATCH v5 05/11] gpu: nova-core: add NV_PFALCON_FALCON_DMATRFCMD::with_falcon_mem()
Date: Fri, 2 Jan 2026 22:59:28 -0600	[thread overview]
Message-ID: <20260103045934.64521-6-ttabi@nvidia.com> (raw)
In-Reply-To: <20260103045934.64521-1-ttabi@nvidia.com>

The with_falcon_mem() method initializes the 'imem' and 'sec' fields of
the NV_PFALCON_FALCON_DMATRFCMD register based on the value of
the FalconMem type.
