Do we have checks when inserting guest TLB for PV dom? Seems not,
Yes, we do. See vcpu.c:check_xen_space_overlap
It's only for xen area (region 7). domU can use full 60 bit VA on
other region in spite of IMPL_VA_MSB = 50.
Eddie,
Ideally we should check it.
But current xen implementation requires full 64bit VA and there is no
such an Itanium2 with IMPL_VA_MSB <60. (except VTi)
So mis-using TLB cannot be. (i.e. unimplemented VA fault never be
happened)
If we support xen on xen, it should be fixed in order to prevent
a guest xen crashing. :)
Thanks,
Kouya
