There is an option to define how many samples to use with the definition of compile time macro "PROFILE_CALLS_SAMPLE" the default value is 10.
The code is guarded by a compile time macro "CONFIG_PROFILE_CALLS", to build execute "make CONFIG_PROFILE_CALLS=1".
When using the added option "-p" we can repeat it up to 3 times:
- "-p" -> Only update calls count and omit functions with 0 calls
- "-p -p" -> Update calls count and sampled time_spent and omit functions with 0 calls
- "-p -p -p" -> Like the above but showing functions with 0 calls.
The output format:
=[ code_line call_count acumulated_time_spent average_time_spent function_name ]
[454 2 1 6 xfillArr]
