hi, never tried on AMD, but AFAIK it exports the event format terms in sysfs like Intel does: [root@krava format]# pwd /sys/bus/event_source/devices/cpu/format [root@krava format]# ls any cmask edge event in_tx in_tx_cp inv ldlat offcore_rsp pc umask and you can use those terms to specify your event more user friendly that using the r* style, like: perf record -e 'cpu/event=0x3c,umask=.../uk' .. jirka > > > 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.
