* crosvm: add vhost_net virtio deviceStephen Barber2017-07-20
| | | | | | | | | | | | | | | | | vhost_net is an in-kernel implementation of a virtio_net device. This device implementation is responsible only for negotiating features and setting up vhost_net to point to the virtqueues in the guest.

* crosvm: mmio register and queue check fixesZach Reizner2017-07-20
| | | | | | | | | | | | | | | | | | | According to the Virtio specification, all MMIO register access must be 32-bit wide and aligned. However, this restriction is not true in general for the config space. This change relaxes the restriction for accesses to config space. This change also checks that each queue is valid before activating a device.

| | | | | | | | | | | | | | | | | | | | Not all types are safe to read from guest memory. Any type with a reference or pointer will be initialized to random bits that don't refer to a valid address.

Provide implementations of `DataInit` for intrinsic types that are obviously safe to initialize with random data.

* crosvm: add virtio MMIO transport moduleZach Reizner2017-06-01
| | | | | | | | | | | | | | | The MMIO transport, along with PCI, is a standard transport for discovering and configuring virtio devices and their associated queues. MMIO is by far easier and simpler and so gets implemented first.
