[Xen-devel] obtaining machine frame number

Hi list,
I am trying to allocate a page at a Linux guest and and obtain the
machine frame number for that page. Then I want to pass the mfn to
dom0 (I need to use xen store since I have my own mechanism to
communicate between guests and dom0) and obtain a struct page for it
(how?) and then dma map it to a pci device. Can some say if/how can
this be done?
