Re: [Qemu-devel] [PATCH v4 6/7] MIPS: Initial support of fulong mini pc (machine construction)

[chen huacai]

Loongson-specific instructions haven't implememted now. So, if want to
boot a linux kernel, we should built a 32bit one and drop
-march=loongson2e compiler flags. For simplification, please use the
kernel patch (for 2.6.33) in the attachment and then use
arch/mips/configs/fuloong2e_defconfig to compile a kernel. Besides,
the disk image I used is debian-lenny built by you which is available
at 
http://people.debian.org/~aurel32/qemu/mipsel/debian_lenny_mipsel_small.qcow2.
