Configurable Perf metrics

The Perf metrics use the Linux kernel perf_event_open() system call to provide additional CPU related metrics available for Linaro MAP.

They can be used on any system supported by the Linux perf command (also called perf_event). These cannot be tracked on typical virtual machines.

Note

This feature is available to use in Linaro Forge Ultimate edition. Contact Linaro Sales for details about how to upgrade.
