Hmm I'm getting this when running a simple record command.

invalid or unsupported event: 'cpu/mem-loads/pp'

This only occurs with c2c, other subcommands work normally. It's as if
it were an old kernel, but it's Linus' latest. Is this an issue with the
patch or something I'm missing?

Furthermore, I see:
ls /sys/bus/event_source/devices/cpu/events
branch-instructions branch-misses cache-misses cache-references cpu-cycles instructions mem-loads

Thanks!
