Currently virtio-pci is specified so that configuration of the device is done through a PCI IO space (via BAR 0 of the virtual PCI device). However, Linux guests happen to use ioread/iowrite/iomap primitives for access, and these work uniformly across memory/io BARs. While PCI IO accesses are faster than MMIO on x86 kvm, MMIO might be helpful on other systems which don't implement PIO or

This adds support for new config, and is designed to work with the new layout code in Rusty's new layout branch. At the moment all fields are in the same memory BAR (bar 2). This will be used to test performance and compare memory, io and hypercall latency. Compiles but does not work yet. Migration isn't handled yet. It's not clear what do queue_enable/queue_disable fields do, not

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, This series adds a virtio_queue_valid() for use by virtio-pci code in order to prevent opreations upon uninitialized VQs, that is currently expected to occur during seabios setup of virtio-scsi. This also includes a vhost specific check for uninitialized VQs in vhost_verify_ring_mappings() to avoid this same case. Please review.
