All the patches except the PMON one seems fine, but I am unable to boot
a kernel. I had to add support for the missing Godson integer
instructions but the kernel (I tried a 2.6.33 one) goes into panic
during the boot:
[ 0.724000] Checking for the daddi bug... no.
[ 0.892000] Cache error exception:
[ 0.892000] cp0_errorepc == 0000000000000000
[ 0.892000] c0_cacheerr == 00000000
[ 0.892000] Decoded c0_cacheerr: primary cache fault in insn reference.
[ 0.892000] Error bits:
[ 0.892000] IDX: 0x00000000
[ 0.892000] Kernel panic - not syncing: Can't handle the cache error!
I got this problem both booting the kernel directly and via PMON. Is
there any other patches missing to be able to use the Fulong 2E
emulation?

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.

It indeed works, however I still think there is a problem. 64-bit
kernels should also boot when dropping -march=loongson2e. Also after
adding the Loongson-specific integer instructions, I am able to boot a
32-bit kernel built with -march=loongson2e, but not a 64-bit kernel.
