[PATCHv6 04/12] qemu/pci: check constant registers on load
Add "cmask" table of constant register masks: if a bit is not writeable and is set in cmask table, this bit is checked on load. An attempt to load an image that would change such a register causes load to fail. Use this table to make sure that load does not modify registers that guest can not change (directly or indirectly). Note: we can't just assume that read-only registers never

[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

Add functions implementing MSI-X support. First user will be virtio-pci.
