[Qemu-devel] [PATCH v2 0/9] PCI capability and device assignment improvements

[Alex Williamson]

v2:

 - Fixed the function name in 1/8 per Michael's suggestion.
 - Removed capability specific config read/write registration
 - Added more checks to add_capability
 - Added capability lookup table to PCIDevice

I've dropped the RFC patch to add more capabilities to device
assignment while I do some more work on it.  Please feel free
to comment on the v1 version though.  Patches still against
qemu-kvm, but I hope some of this makes it easier to bring
qemu & qemu-kvm closer here.  Thanks,

Alex

v1:

This series attempts to clean up capability support between common
code and device assignment.  In doing so, we can move existing MSI &
MSI-X capabilities to offsets matching real hardware, and further
enable more capabilities to be exposed.

The last patch is only for RFC, I'd like some input on what we should
pass directly and where we should only provide read-only/emulated
access.  Patches 1-7 are submitted for commit.  Thanks,

Alex
