Subject: [PATCH] perfc_defn.h - increase VMX reason size array
Date: Wed, 08 Mar 2006 21:14:01 -0500	[thread overview]
Message-ID: <440F8F69.7060507@virtualiron.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 655 bytes --]

If I'm reading the spec correctly, the April 2005 Intel Virtualization
Technology Specification (Appendix A1) indicates that there are 44
potential exit reason codes.  Based upon this, increase the size of
the PERFCOUNTER_ARRAY for vmexits.
