tsprof (by John Reiser, jreiser@BitWagon.com)
http://www.BitWagon.com/tsprof/tsprof.html
A profiling application which uses the facilities provided
by the perfctr driver.
lperfex (by Troy Baer, troy@osc.edu)
http://www.osc.edu/~troy/lperfex/

msr-patch-2.3.1 (by Richard Gooch, http://www.atnf.csiro.au/~rgooch/linux/)
Adds /dev/<cpu>/perfmon with access to per-CPU PMCs.
Does not implement virtual-mode PMCs.
Does not handle counter overflow.
Part of bigger package (MSRs, requires devfs).
pperf/libpperf (by M. Patrick Goda, http://qso.lanl.gov/~mpg/pperf.html)
Based on Stephan Meyer's msr patch, and shares its limitations.
Emphasis on user-space tools.
pcl (by Rudolf Berrendorf and Heinz Ziegler,
http://www.fz-juelich.de/zam/PCL/)
User-space tools, based on libpperf.
PAPI (http://icl.cs.utk.edu/projects/papi/)
"Portable Interface to Hardware Performance Counters"
Common interface to the perfctr facilities on several
operating systems and processor architectures.
On Linux, uses Hendriks' "perf" patch for Intel P6 processor.
User-space tools. Implements both overflow signals and
event multiplexing.
pmc-1.02 (by Don Heller, dheller@scl.ameslab.gov)
http://www.scl.ameslab.gov/Projects/Rabbit/index.html
Derived from pperf by M. Patrick Goda and Michael S. Warren.
