I am trying to use PAPI with PCL to profile an application using Atom. Ideally I would like to use Ubuntu 9.10 or 10.04 that has kernel version >= 2.6.31 so I don't have to patch the kernel.
But in the readme file it says that support for PCL is still experimental (pre-release sort of) and that not all processors are supported. Does anyone know whether I can reliably use PAPI with PCL without kernel patches or whether I will have to patch the kernel with the PerfCtr patches for it to work on Atom?
I don't want to be dealing with bad data.
Thanks for reading,
