Here's a new version of MSI-X support patchset. I have completed save/load support, and added a global option to disable MSI-X.
This is on top of qemu-kvm.git/queue Todo: split patch up, support configurations without kernel irqchip, apply to upstream qemu.git. Anthony, please take a look at capability bit support that I added in pci save/load. Does it look sane? Simple version number is not sufficient for msi, because user has an option to turn off msi even in new qemu. Signed-off-by: Michael S. Tsirkin <[email protected]> Michael S.
