Re: [Xen-users] xc_memory_op not found in Xen 4.1

["S. Shary" <justsshary@xxxxxxxxxxx>]

What will be the alternate for the following two situations of xc_memory_op?

1. /* Get the size of the P2M table */
    //p2m_size = xc_memory_op(xc_handle, XENMEM_maximum_gpfn, &dom) + 1;


2.  if ( xc_memory_op(xc_handle, XENMEM_machphys_mfn_list, &xmml) ||
               (xmml.nr_extents != m2p_chunks) )
    {
        ERROR("xc_get_m2p_mfns");
        goto err1;
    }


If i just substitute with xc_maximum_ram_page(xc_handle), would that be correct? I could not find xc_maximum_ram_page with more than one arguments to substitute over here.

Thanks,
Regards,
Shary
