Hi, I think that the format you are using is not correct.
To profile event 0xXXX with unit mask YY, the format is rX0000YYXX, so in your case: r1000002e0. Also, beware that the unitmask in the documentation tells you the _bit(s)_ that need to be set. So : From Local Node to Node 0 = r1000001e0 From Local Node to Node 1 = r1000002e0 From Local Node to Node 2 = r1000004e0 From Local Node to Node 3 = r1000008e0 From Local Node to Node 4 = r1000010e0 From Local Node to Node 0 & 1 & 2 = r1000007e0 etc. Cheers, Baptiste. ----- Mail original ----- > De: "Martin Ichilevici de Oliveira" <martin.i.olive...@gmail.com> > À: linux-perf-users@vger.kernel.org > Envoyé: Mardi 18 Février 2014 17:51:46 > Objet: Event not supported > > Hello, > > I'm still learning perf, so I apologize in advance if my questions are > too simple and not suited here.
