[PATCH 0/11] RFC: PCI using capabilitities
Here's the patch series I ended up with. I haven't coded up the QEMU
side yet, so no idea if the new driver works.
Questions:
(1) Do we win from separating ISR, NOTIFY and COMMON?
(2) I used a "u8 bar"; should I use a bir and pack it instead? BIR
seems a little obscure (noone else in the kernel source seems to
refer to it).
Cheers,
Rusty.

[PATCH 00/22] New virtio PCI layout
I've renewed this again, with some comments from HPA. I've tried to
keep the new patches separate, so you can see the changes since we
last discussed this (and so it's easy to back it out if we decide it's
insane).
I haven't even looked at the QEMU side so this is completely untested.
Comments gratefully received!
Rusty.
