This patch series adds support and enablement of the pause filtering threshold. Once there's pause filtering threshold amount of cycles between pauses, the pause filtering counter resets to what was in the VMCB. This allows the pause filtering count to "reset" between pauses and keeps the guset from getting intercepted by the hypervisor. See AMD APM vol 2 section 15.14.4 for more details.
In reply to this will be an email with graphs showing some benchmark results of why the values of the counter and threshold were picked.
