Here's an updated vesion. I'm alternating between updating the spec and the driver, spec update to follow. Compiled only. Posting here for early feedback, and to allow Sasha to proceed with his "kvm tool" work. Changes from v2: address comments by Rusty bugfixes by Sasha Changes from v1: Updated to match v3 of the spec, see: todo: split core changes out Signed-off-by:

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. Michael S Tsirkin (1): pci: add pci_iomap_range

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.
