  • Thread-topic: PIO from domU

We’re looking on sharing iWARP adapter by multiple guest domains, and having a direct adapter access.

 

Does Xen/dom0 have a mechanism to map a page from adapter PCI address space to the domU memory space, and make it accessible by kernel/user space consumers running in domU?

 

Thanks,

Vadim Makhervaks

Sr. Architect, NetEffect
