The idea behind the virto platform driver is to have a reusable layer
that handles common virtio and vring functionality. Regular virtio
drivers for console, network and disk and interfacing to the virtio
platform driver, so these paravirtualized drivers can with this virtio
platform driver easily be reused by embedded platforms.
Vendor specific code is abstracted away from the virtio platform
driver and interfaced to using regular interrupts and SoC-specific
callbacks. So with this patch virtio can be interfaced as any regular
platform driver. This version of the driver is simply reusing the
configuration method from lguest.
If you want to see all code involved (including extremely experimental
backing drivers) then have a look at:
