Performance Counter Tools?

Hello,

Can anyone point me to tools that run on DragonFly which access CPU
performance counters? Tools like likwid run only on Linux, requiring the
"msr" kernel module (arch/x86/kernel/msr.c), or others use some
Linux-specific APIs, such as perf_events (the Perf tool).

If there are none, what would be required to support one of the common
tools? Could we port the MSR API from Linux (even as a hack, initially)?

Thanks!
Alex
