Hi Christoph,
Thank you for quick reply.
If we want to add this in vfio then I think we need to do the same in uio case also.
As I mentioned in previous mail, in the current implementation resource information (address and size) is gathering from resource named file created in /sys directory. So I expect it would be better to have similar method as existing in sysfs.
Regards, Srinath.
