[Qemu-devel] Cavium Networks' Octeon hardware gets simulated

[Dmitry Antipov]

Hello all,

I would like to announce the first successful emulation of Cavium Networks' Octeon
hardware (http://www.caviumnetworks.com/OCTEON_MIPS64.html). I'm using heavy modified
QEMU 0.12.2 and MontaVista's CGE 5.1 (http://www.mvista.com/product_detail_cge.php) as
the target Linux system. But I suppose it shouldn't be too hard to enable community-based
kernel and user space applications too.

Devices emulation is very limited (serial port, on-board flash and smc91 network card
instead of native and very sophisticated Octeon's network chip), but the whole system
is quite usable to run full-featured user space via NFS root.

My QEMU modifications are quite dirty (other MIPSes are broken with them), and most
probably needs some rewrites and/or massive cleanups before even making an attempt to
merge them into main tree. But if we have a few persons interesting with this work,
I'll be glad to announce the code and work with the maintainer(s) to get the code in.

Thanks in advance,
Dmitry
