This is a new driver to enable userspace networking on VMBus. It is based largely on the similar driver that already exists for PCI, and earlier work done by Brocade to support DPDK.

Enable this to allow the userspace driver core code to be

built. This code allows userspace programs easy access to

kernel interrupts and memory locations, allowing some drivers

to be written in userspace. Note that a small kernel driver
|

is also required for interrupt handling to work properly.

Platform driver for Userspace I/O devices, including generic

This kernel driver requires that the matching userspace driver

handles interrupts in a special way. Userspace is responsible
|

for acknowledging the hardware device if needed, and re-enabling

interrupts in the interrupt controller using the write() syscall.

Memory regions can be specified with the same platform device

resources as the UIO_PDRV drivers, but dynamic regions can also

be specified.

The number and size of these regions is static,

the associated device file is opened. The

memory is freed once the uio device is closed.
