This patch adds a driver for my shared memory PCI device using the uio_pci
interface. The driver has three memory regions. The first memory region is for
device registers for sending interrupts. The second BAR is for receiving MSI-X
interrupts and the third memory region maps the shared memory. The device only
exports the first and third memory regions to userspace.
This driver supports MSI-X and regular pin interrupts. Currently, the number of
MSI vectors is set to 4 which could be increased, but the driver will work with
fewer vectors. If MSI is not available, then regular interrupts will be used.
There is now a generic PCI 2.3 driver that can handle all PCI devices.
It doesn't support MSI, but if we add MSI support then it can be used
without the need for a specialized driver.
