The GSP boot support [1][2] has now been fully merged into drm-rust-next,
which puts us in a good position to start discussing the requirements for
bringing up GSP with vGPU enabled.
Booting up GSP with vGPU enabled is a key short-term milestone for upstream
vGPU support, allowing us to validate the basic GSP boot flow with vGPU
enabled even before the remaining nova-core dependencies are ready.
This RFC series builds on top of the latest drm-rust-next with kernel
module param support from [3]. A tree can be found [4].
