linux-conf-perf

This is tool for automatic performance analysis. It calculates impact on performance per symbol.

TOOL IS IN DEVELOPMENT AND NOT WORKING PROPERLY

Folders

• scripts In this folder are all python scripts
  • pase_kconfig Contains program for extracting dependences from Kconfig files to format for PicoSAT.
  • write_config Fixes configuration and compares it against generated one.
  • permute_conf Interactive program for setting measure base.
  • shared Shared files
  • novaboot Script Novaboot
  • picosat-959 Program PicoSAT
• jobfiles In this folder are placed files generated with local scripts.
• output Contains output of executed boots.
• result In this folder are expected to be files with values from benchmarks.
• log To this folder are logged all program outputs.
• linux Submodule of linux kernel
• buildroot Submodule of Buildroot

Configuration files

Main configuration is in file conf.py and has python syntax. Important settings are commented inside file. Configuration must be done before executing make run or make init.

Usage

Before any other steps, create Linux configuration and setup boot target with benchmark. You can run make test for testing if setup is correct.

For configuration of measured symbols, run make mpermute_conf.

To execute tests, run make run.

Output of benchmarks must be analyzed after execution of all different configurations. Files in folder output contains benchmark outputs. You should ensure, that values for benchmark are extracted and saved to folder result to file with same name as source.

Final evaluation is done by make evaluate.
