[Xen-devel] support for sharing huge pages with grant table?

[Tim Wood <timwood@xxxxxxx>]

Hi,

I am curious if Xen currently supports sharing hugepages between domains (specifically ones originally allocated in Dom-0 and shared with a guest r/w). I've seen some references to huge pages in the archives of this list, but not in relation to the grant mechanism.

Also, can someone confirm that "superpages" are another term for "huge pages" in Xen?

This would be helpful for some work we are doing on high speed networking to VMs---DPDK stores packets into huge pages and we'd like to get those to VMs as quickly as possible.

thanks!
Tim
