Problem: {Unknown Timer} in the Platform Power Analysis Viewpoint

Platform Power Analysis viewpoint displays an
{Unknown Timer}
with a blank process name and
{Unknown}
PID/TID.

Cause

The kernel configuration prevents the
VTune
Profiler
from collecting the required data: it cannot identify the PID/TID/module or process name for the timer.

Solution

You may set the CONFIG_TIMER_STAT =Y in the boot configuration file and recompile the kernel.
