Re: [PATCH] compilation fix of ia64 hypervisor.c, utils.c (was Re:[Xen-i
Hi.
Maybe I understand the cause.
It's side effect of CONFIG_VIRTUAL_FRAME_TABLE.
If CONFIG_VIRTUAL_FRAME_TABLE is defined, there is no page_info's
corresponding to ACPI table pages.
Thus set_gpfn_from_mfn() in assign_domain_page() causes dtlb fault
and xen dtlb miss handler falls to frame_table_fault and then
dispatch_to_fault_handler().
This is fixed by the patch balloon_driver_xen.patch
which I will post soon.
BTW
ia64_fault()
case 4:
printk("Alt ITLB.\n");
break;
Should This be "Alt DTLB"?
Thanks.
