Hi Experts,
Is there in-built Performance Monitor Unit Driver available in the Linux kernel ?
Does it have the user space access to test the same ?

Hi Jerome,
I mean the Performance Counters in the ARM Cortex processors.

In most kernels and distros on ARM you have full access to the system counters and CPU counters. You have a few options for accessing them; obviously, system counters are available through the proc filesystem. Other counters are most easily monitored by perf or gator. The latest version of the gatord used with Streamline do not require a kernel module to read most of the counters. Are you attempting to use a specific performance monitoring tool?
