Hi

As of Intel SDM (https://www.intel.com/sdm) version 076, there are 2 new
Intel PT features called Event Trace and TNT-Disable.

Event Trace exposes details about asynchronous events such as interrupts
and VM-Entry/Exit.

TNT-Disable disables TNT packets to reduce the tracing overhead, but with
the result that exact control flow information is lost.

Tools patches are being sent in a separate patch set, but can be found
here:

      perf/x86/intel/pt: Add a capability and config bit for event tracing
