Subject: [PATCH v4 6/8] gpu: nova-core: gsp: shuffle boot code a bit to keep chipset-specific parts close
Date: Mon, 27 Apr 2026 15:57:03 +0900 [thread overview]
Message-ID: <20260427-nova-unload-v4-6-e145ccddae66@nvidia.com> (raw)
In-Reply-To: <20260427-nova-unload-v4-0-e145ccddae66@nvidia.com>
Some parts of the GSP boot process are chip-specific actions, whereas
others (like sending the initial post-boot messages) deal directly with
the working GSP.
Reorganize the boot code a bit so the chipset-specific parts are clumped
together, which will make their extraction into a HAL easier.
This has no effect on the GSP boot process.
