[Qemu-devel] pciproxy status?

[Karsten N. Strand]

Hi,
First I must say that I'm extremely impressed with the development of 
qemu, and that I think it's currently one of the most technical 
interesting open source projects these days. Then the question..

What's the status of the pciproxy patch? Is it still work in progress, 
or have it stalled now? What about pci DMA support?

The reason I ask is because I want to try to reverse engineer my 
EMU-1820 pci soundcard, with the intention of getting it supported in 
linux. And qemu with pciproxy support seems like the perfect tool for 
this job.

My progress so far:

Got the newest qemu cvs to compile with the pciproxy 0.3 patch with a 
few modifications, installed Windows XP without any troubles at all (I'm 
impressed! :), and booted up qemu-softmmu with -pciproxy 02:06.2 (or 
something like that). The card was detected in the virtual machine, and 
I started installation of the driver. After accepting the unsigned 
driver, qemu hanged, and I couldn't get any response in the vm.

At that point I had to go to bed (3 hours sleep before work is a minimum 
:P), so I haven't had the chance to investigate the hang further yet. 
However I suspects that in any case it probably needs DMA support 
through the pci proxy, since soundcards usually do..

If anyone is interested I can post the updated patch later (right now 
I'm at work, and the code is at home). Any thoughts or comments on this  
would be very appreciated :)

Kind regards,
