Hi,
what exactly does this module do?
I have got about 1 million after calling this function for a domain with 1
Gigabyte ram and page size 4K. If the output of the function is the whole
gfns in a domain, shouldn't it be equal with (ram-size)/(page-size) ?
Is there any API to get the memory range of the domain to search through
its pages ?

The function xc_domain_maximum_gpfn returns the highest frame that has
ever been mapped in the p2m.
