Hi,

The folowing patch upgrades the perf with extended performance event description, as proposed in a separate RFC.
You can find it here: http://article.gmane.org/gmane.linux.ports.arm.kernel/72822

It has been tested on a ARMv7 Cortex-A8 incarnation.
Event names can be specified to -e switch, and are reported in the list command.

The perf-predefined commands take precedence (if a collision occurs) over the platform-specific ones.
A workaround for that is though - specify the raw event, as seen provided by the system.
Currently it resides in the sysfs, but I've already been pointed to a sysfs note disclaiming mixed types, multiple lines and fancy formatting. Might swith over to debugfs.


Thanks,
