Hey,

Two full days i am tring to understand how to use the Linux Performance Monitoring Unit on my Sabre Lite.

 

I have the LXDE Trusty Ubuntu Linux 3.14.28 from Boundary Devices.

 

I am tring to install : GitHub - thoughtpolice/enable_arm_pmu: Enable user-mode access to ARMv7/Linux performance counters

 

but i always have his error : Compilation error : Syntax error · Issue #4 · thoughtpolice/enable_arm_pmu · GitHub

 

I am pretty sur the thing a want to do is possible : linux-imx6/pmu.txt at master · samnazarko/linux-imx6 · GitHub

 

but I don't understand what i am doing wrong ...

 

I also try to look into the kernel option, and i have this option selected in the kernel menuconfig: “Kernel performance events and counters” which is found under “General setup" then under "Kernel Performance Events and Counters” .

(ref . Using the ARM Performance Monitor Unit (PMU) Linux Driver  )

 

 

does't someone success to did it?
