Both the FSP boot path and the upcomingGSP RPC message queue share this protocol layer.Signed-off-by: John Hubbard <jhubbard@nvidia.com>Reviewed-by: Eliot Courtney <ecourtney@nvidia.com>Link: https://patch.msgid.link/20260603-b4-blackwell-v13-3-d9f3a06939e0@nvidia.comSigned-off-by: Alexandre Courbot <acourbot@nvidia.com> List of files: /linux/drivers/gpu/nova-core/mctp.rs Wed, 03 Jun 2026 09:30:20 +0200 John Hubbard <jhubbard@nvidia.com>
