Hi Stephen,
Here is the latest patch that supports interrupts. I am currently
working
on a broadcast mechanism that should be ready fairly soon.
http://patchwork.kernel.org/patch/22368/
I have some test scripts that can demonstrate how to use the memory
between
guest/host and guest/guest. Let me know if you would like me to
send them
to you.
Hi Cam,
Thanks for the pointer. That makes perfect sense, I'm familiar with
PCI drivers so that's fine.
Is there a corresponding qemu patch for the backend to the guest pci
driver?
Oops right. For some reason I can't my driver patch in patchwork.

I'm curious how the buffer memory is allocated and how BAR
accesses are handled from the host side.
The memory for the device allocated as a POSIX shared memory object
and then mmapped on to the allocated BAR region in Qemu's allocated
memory. That's actually one spot that needs a bit of fixing by
passing the already allocated memory object to qemu instead of
mmapping on to it.
