A little question

Hello, I have read your relevant paper, can I use femu to reproduce the relevant work without using openssd platform

It makes sense to port the functionalities of lambda-io to FEMU. You can try to port lambda-device (nvme-ctl and uebpf-rt) to FEMU and run lambda-kernel in the guest OS. Specifically, nvme-ctl contains the logic to parse, process, and complete an NVMe command. You should merge it into the FEMU NVMe controller. uebpf-rt provides the sBPF/eBPF runtime on both aarch64 and x86-64. Please pay attention to your machine's ISA. You should compile uebpf-rt to x86-64 if you run FEMU on an x86-64 machine and link it to FEMU.
