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].
