A goal will be to squeeze out maximum performance and/or minimum-size. so I'm wondering would a BSP layer deliver any benefit? The Firecracker VM has a very small device list, with support for Intel x86_64 and ARM64 CPU's. The devices are: "only 5 emulated devices are available: virtio-net, virtio-block, virtio-vsock, serial console, and a minimal keyboard controller used only to stop the microVM"
In that case a tuned kernel build in a dedicated BSP would make sense, yes.
