[PATCH RFC 0/2] virtio-pci: polling mode support
MSIX spec requires that device can be operated with
all vectors masked, by polling.
So the following patchset (lightly tested) adds this
ability: when driver reads ISR, the device
recalls a pending notification, and returns
pending status in the ISR register.
The polling driver can operate as follows:
- map all VQs and config to the same vector
- poll ISR to get status - this also flushes VQ

[PATCHv6 05/12] qemu/pci: MSI-X support functions
Add functions implementing MSI-X support. First user will be virtio-pci.
Note that platform must set a flag to declare MSI supported: this
is a safety measure to avoid breaking platforms which should support
MSI-X but currently lack this in the interrupt controller emulation.
For PC this will be set by APIC.

[PATCHv2 RFC] qemu/msix: remove msix_supported safety flag

emulation.

This patch on top of my msix series v6 is a bit tongue in cheek: it
shows what can be done and Paul seems to think it's a good idea. So even
though I don't necessarily agree,
