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

Note: Download GUEST.patch from the following link:

• 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:

Octeon ebh5610# bootoctlinux
