I hate to sound like a broken record here, but, again, what's the 
rationalization for not using libpfm4 here?

Is it simply NIH or is there some sort of technical reason?  It seems a 
lot of wasted effort to create all these tables one chip at a time when 
libpfm4 already has well-tested and debugged event tables for most CPUs 
with perf_event support.
