Calculating time taken in uefi application.

[ayushdas2000]

Hi Kostr. Thanks for the lessons first.I want to calculate how much time does my application take to run. I am trying to use ticks to calculate time elapsed. Basically this using the PerformanceLib and TimerLib :
Frequency = GetPerformanceCounterProperties(NULL, NULL);
StartTick = GetPerformanceCounter();
EndTick = GetPerformanceCounter();
ElapsedTicks = EndTick > StartTick ? EndTick - StartTick : StartTick - EndTick;
TimeInSeconds = (double)ElapsedTicks / Frequency;
I am getting 0 seconds everytime. Any leads for this ? Thanks in advance.

Tried a lot of things like printing in nanosecs and as string but always getting 0. Any other approach would also help. Thanks

    Could you look at this error please. Thanks

Is the module where you try to use these library functions a PEI module?

No module type is UEFI application
