I don't think r100b is a valid event on Westmere.
Thanks for the replies.
As Harald Servat and others pointed I am now trying "perf mem record"
[root@rafa cms]# ./perf mem record /bin/ls
invalid or unsupported event: 'cpu/mem-loads/pp'
Is this a issue with the (old) kernel version I am on or the CPU version or
both.

I'm using
Linux laptop 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC
2013 x86_64 x86_64 x86_64 GNU/Linux
so I imagine that you're ok with respect to OS. Now I remember I had
to install some microcode module for my OS, though [2]. WRT hardware,
I'm running on top of a
vendor_id : GenuineIntel
cpu family : 6
model : 42
model name : Intel(R) Core(TM) i7-2760QM CPU @ 2.40GHz
stepping : 7
Besides of that, the Intel Manual [1] says in section 18.7.1.1 that
Nehalem (and I'd would guess Westmere, as it is a Nehalem successor)
supports PEBS, so it should work.
Best regards.
