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:

}
