Would you please kindly tell me the full name of '*via*'?
Thanks

Thanks. The implementation use 'via' as param name and 'a' as local
variable which makes me think `via` is an abbreviation of something. Seems
wrong.
int xen_set_callback_via(uint64_t via)
{
struct xen_hvm_param a;
a.domid = DOMID_SELF;
a.index = HVM_PARAM_CALLBACK_IRQ;
a.value = via;
return HYPE
crash leaving an incomplete log.
How can I make it flush log buffer more frequently or how can I get a full
log/backtrace before system crash?
I'm using serial ttyS2 to debug xen. dom0 earlyprink is xen.
Thanks!

confused about this because new PT also has same mapping. The only
difference is address of page table page and hypervisor should have no
knowledge of this.
Does anyone know this? Or what docs should I refer to?
Thanks
