Are you trying to make driver layers here and each virtio device driver can hook up into this platform driver. Is that correct ? 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: http://www.spinics.net/lists/linux-sh/msg07188.html Cheers, / magnus _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
