I just tried running it and got a failure with an exit status of 255:
# perfquery -x
ibwarn: [30842] dump_perfcounters: PerfMgt ClassPortInfo 0x0; No extended
counter support indicated
perfquery: iberror: failed: perfextquery
This is on RHEL5 with infiniband-diags-1.5.12-2.el5
Let me know if you need me to test out anything else.
