Re: qemu direct kernel boot on LoongArch

Jason, With the latest qemu 9.1 version, elf format booting is supported. Qemu 9.0 does not support it still, here is example command line. ./qemu-system-loongarch64 -m 4G -smp 2 --cpu la464 --machine virt -serial stdio -monitor telnet:localhost:4495,server,nowait -kernel /root/linux_larc

Re: qemu direct kernel boot on LoongArch

Thomas, Thanks for reporting this issue. It is the problem of QEMU for LoongArch system, QEMU does not support booting vmlinux with elf format without UEFI bios now. We will add support to boot vmlinux directly on QEMU LoongArch side. Regards Bibo Mao 在 2023/10/10 上午4:13, Thomas Weißschuh 写
