Subject: [PATCH v10 05/10] gpu: nova-core: falcon: remove unwarranted safety check in dma_load
Date: Sun, 01 Mar 2026 23:03:48 +0900 [thread overview]
Message-ID: <20260301-turing_prep-v10-5-dde5ee437c60@nvidia.com> (raw)
In-Reply-To: <20260301-turing_prep-v10-0-dde5ee437c60@nvidia.com>
This safety check was an assumption based on the firmwares we work with
- it is not based on an actual hardware limitation. Thus, remove it.
