[Qemu-devel] Firewire/IEEE1394 OHCI for QEMU

[Peter McCormick <pete@blonos.com>]

Hello all,

I'm working to create an OHCI-compliant Firewire virtual device for 
QEMU. There is not a solid story on how to connect the guest device to 
the host operating systems' Firewire stack, but I might end up modifying 
the Linux ohci1394 kernel module to allow for a more generic passthru 
interface (for those familiar with krh's "nosy" sniffer, something in 
that direction, albeit with the OHCI no-snoop-mode limitations.)

http://github.com/pmccormick/qemu-firewire-ohci/tree/ohci1394
(it is forked from of git://repo.or.cz/qemu.git, which I periodically 
rebase off of)

At the moment I am still very early on in the implementation, not even 
DMA contexts for async/iso are functional yet. But I have been inching 
along getting Windows XP and Linux guests to recognize the presence of 
an OHCI device.

If anyone has experience with this stuff, or an interest to help, please 
get in touch!!

Cheers,
Peter
