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
