hello all,

i am  new to xen-development and currently trying to understand memory mgmt in hvm mode
I am writing a hypercall which takes input of virtual address of domu. hypercall translate this address to machine and return 4kb page from thereafter.
Inside hypercall, i m using  paging_gva_to_gfn function but it returns -1 instead of returning valid gfn.

what wrong with my approach.
