[perfmon2] multiplex.c

[Pradeep R. <pra...@is...>]

Hello,

I have some trouble getting the multiplex.c example to run on my platform: 
kernel 2.6.25, Opteron model 254

Any idea what I'm missing ? (systemwide monitoring using pfmon works though;)


$ multiplex --verbose --system-wide -k -- ../../pfmon/tests/noploop
