Xen devel - Apr 2010 - xc_domain_memory_populate_physmap | Number of hypercalls

Hi,

I am facing an issue. I am doing a xc_domain_memory_populate_physmap inside
the following function in xc_hvm_build.c (xen - 3.4.1)

" static void build_hvm_info(int xc_handle, uint32_t dom, void
*hvm_info_page, uint64_t mem_size, uint64_t e820rc)
{
.
.
.

                if (xc_domain_memory_populate_physmap(xc_handle, dom,
                                         (e820rc_size >> XC_PAGE_SHIFT),
/*nr_extents */
                                         0, /*extent_order */
                                         XENMEMF_raid_cache, /* mem_flags */
                                         &page_array[0x00]))
.
.
.
"

I need to know how many hypercalls will it generate ?
Or How many times will it hit the following Switch Case

"
long do_memory_op(unsigned long cmd, XEN_GUEST_HANDLE(void) arg)
{
.
.
    case XENMEM_populate_physmap:
.
.
}
