A first iteration of the series has already been posted as "Vm_event
memory introspection helpers", consisting of five patches:
[PATCH 1/5] xen/vm_event: Added support for XSETBV events
[PATCH 2/5] xen/vm_access: Support for memory-content hiding
[PATCH 3/5] xen/vm_event: Support for guest-requested events
[PATCH 4/5] xen/vm_event: Deny MSR writes if refused by vm_event
[PATCH 5/5] xen: Write CR0, CR3 and CR4 in arch_set_info_guest()
It has also been fairly discussed, and the first patched morphed into
the "[PATCH V10] xen/vm_event: Clean up control-register-write vm_events
and add XCR0 event" that I've posted today, and acked by Jan Beulich,
Kevin Tian, Ian Campbell and Tim Deegan. The XSETBV event in question is
the new XCR0 event.
As soon as this patch goes in, I'll see what can be whipped into shape
from the remaining patches (they depend on it) and submit V2 of the series.
Thanks,
Razvan
