[Xen-ia64-devel] use of imp_va_msb in VTi

[Tristan Gingold <Tristan.Gingold@xxxxxxxx>]

Hi,

unimplemented_gva use imp_va_msb field of domain.arch:

int unimplemented_gva(VCPU *vcpu,u64 vadr)
{
    int bit=vcpu->domain->arch.imp_va_msb;
    u64 ladr =(vadr<<3)>>(3+bit);
    if(!ladr||ladr==(1U<<(61-bit))-1){
        return 0;
    }else{
        return 1;
    }
}

But I didn't find where it is written.  Any hint ?

Thanks,
Tristan.
