Summary

This patch is the first in the series of patches that add a new provider in DTrace called vmm. It is meant to hold all of the bhyve-related kernel probes. In this particular patch, only VMX probes for the VMexit interface were added.

The purpose of these probes is to aid in debugging VMexit-related problems directly in the VMX interface without having to enable KTR (and in turn wait a very long time to get a trace).

Event Timeline

Should I make any more changes for this to land? As an aside note: I've tried to make the interface as simple as possible to use with the args[0-2] being consistent.

I think this should be fine. Can always be tweaked later.
