QEMU-Octeon-MIPS64 Patch

Patch for the emulation of Octeon MIPS64 in QEMU

Preparing HOST

Download qemu-1.0.1 tar
cd and run export CFLAGS='-lm -lrt' ./configure --target-list=mips64-softmmu make
copy patch to qemu-1.0.1 top directory patch -p1 > host.patch make
modified Qemu binary "qemu-system-mips64" is found in qemu-1.0.1/mips64-softmmu

Preapring GUEST

OCTEON-SDK-2.0.0
extarct & apply the guest.patch
make the kernel

To Run single Core version:

./qemu-system-mips64 -m 256 -M octeon -nographic -bios /u-boot-octeon_ebh5610.bin -kernel /vmlinux.64 -append 'coremask=0xfff mem=0 root=/dev/sda2'

when uboot command promt occur:
