you can use xc_translate_foreign_address to get a the mfn of a give virtual address

2008/7/9 吴佳民 <wujiamin_tyut@xxxxxxx>:

Hi:
    I wanna write code about sharing memory between dom0 and domU, and I decide to use void *xc_map_foreign_range(int xc_handle, unint32_t dom, int size, int port, unsigned long mfn) (this is a function in xenctl.h).
   My question is :
   If I wanna map a range of memory in dom0 to domU, how can I　get the value of mfn? and I do not know the port here.

   Can anybody help me ?
   Thanks .

                                                                Danius Wu
