problem with qemu-system-loongarch64

[Waldemar Brodkorb]

Hi Qemu developers,

I am trying to bootup a loongarch64 Linux kernel in Qemu 7.1.0-rc2.
The problem is I get no output when using following command:
qemu-system-loongarch64 -M virt -nographic -kernel vmlinux

You can find my vmlinux initramfs here:
https://debug.openadk.org/vmlinux

It is cross-compiled with binutils 2.39, gcc 12.1, glibc 2.36 and
Linux 5.19. I use the provided defconfig loongson3_defconfig for the
kernel build.

Any hint what I can do to get a bootable Linux image?

best regards
 Waldemar
