[Xen-devel] Vm_event memory introspection helpers

[Razvan Cojocaru <rcojocaru@xxxxxxxxxxxxxxx>]

Hello,

Since the first version of the series, which consisted of five patches,
the following major changes have happened:

1. The first patch in the previous series has already been accepted,
under the name "xen/vm_event: Clean up control-register-write vm_events
and add XCR0 event". The patch was "xen/vm_event: Added support for
XSETBV events" - the XCR0 is the previously-named XSETBV event.

2. It has been decided that having a single DENY vm_event flag that
applies to both CR and MSR writes is not an outlandish idea, and as
such the last patch (patch 5) from the previous series has been
removed, and the CR0, CR3 and CR4 write events are now being sent
as pre-write events, to be denied the same way as the MSR writes
are, in patch #3.

So the current version now went from 5 patches to 3:

[PATCH V2 1/3] xen/vm_access: Support for memory-content hiding
[PATCH V2 2/3] xen/vm_event: Support for guest-requested events
[PATCH V2 3/3] xen/vm_event: Deny register writes if refused by
vm_event reply.


Thanks,
Razvan Cojocaru
