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
David:
It looks like you're running on an older Intel processor, which is missing
necessary events for C2C to work.
As Don noted in his patch 00/19, this was primarily developed and tested on
Intel's Ivy Bridge platform.
If you rerun this on an Ivy Bridge, it should work fine.
We should add a runtime check for supported platforms.

Thanks!
