Re: [Xen-devel] Porting linux network driver to Xen



Native Linux drivers should work as such in Dom0. You don't have to port them.

Hi All,

I am working on porting an existing network driver from Linux to Xen, I understand network drivers needs netback and netfront functionality in order to work in Xen but I am unable to nail down the details of changes required esp.

a. will the existing driver go into hypervisor or dom0?
b. what changes are required in TX/RX rings for DMA in existing driver and how to incorporate them into netback/netfront,
c. handling IRQs...

Any pointers to existing nic driver or pointer to a document would be really helpful.

Thanks
-RK
