We're working on implementing a virtual NVMe controller based on SPDK and a multiprocess-qemu branch that uses the vfio-user. We're facing a problem where the existing API doesn't allow us to tell QEMU from which NVMe namespace we'd like SeaBIOS to boot from.
How can we solve this problem? Can we add a parameter to the '-boot' option, e.g. '-boot path=/devices/pciblah/...@namespace0'? AFAIK VFIO should have the same problem. The corresponding SeaBIOS patch can be found in https://mail.coreboot.org/hyperkitty/list/seab...@seabios.org/thread/2Q7NPH7TJNHK6JGPHQL7755HILO23ISN/
