v3:
- Rework to avoid introducing conflicts with qemu.git hw/pci
- Drop capability lookup table
- Add back minimal device assignment PM, EXP, X, VPD, VNDR
capabilities
This version should do a much better job at not introducing new
differences between qemu-kvm.git and qemu.git hw/pci. The diff
between the pci files after this series is significantly
reduced. I added back the previous RFC patch that adds new
capabilities for assigned devices. I'm sure we'll want to add
passthrough for various fields, but that can come later (along
with figuring out whether we can consolidate emulation should
other drivers want it). Thanks,
Alex
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.
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.
