[Xen-ia64-devel] regarding dom_fw_setup

[jeet <jeet_sat12@xxxxxxxxxxx>]

Hi All

I am looking into code of construct_dom0()

which call dom_fw_setup() to setup the firmware related mapping in 
domain identity mapped virtual address space

But in dom_fw_setup() it there is a code as below

<snippet start>
  /* Create page for acpi tables.  */
       if (d != dom0) {
            void *imva;
 
             assign_new_domain_page_if_dom0(d, FW_ACPI_BASE_PADDR);
                 imva = doamin_mps_to_imva (d, FW_ACPI_BASE_PADDR);
                dom_fw_fake_acpi(d, (struct fake_acpi_tables *)imva);
        }
<snippet end>

here if it is not dom0 then it call 
assign_new_domain_page_if_dom0

but inside this it checking if dom=dom0 then it assign page otherwise return
So what is purpose of this code here?

or the check should be if (d == dom0) ?

jeet
