Build Flow Tutorials


This tutorial uses both Vitis and PetaLinux tools. It is recommended to use separate shells for each of the tools.

Perfapm-server Application

perfapm-server
perfapm-server


The performance monitor server application perfapm-server is a bare-metal application that executes on RPU-1. The firmware binary is loaded by the APU master at the end of the Linux boot process. RPU-1 and APU establish a communication channel using the OpenAMP framework. RPU-1 gathers performance data like memory throughput from the PS AXI performance monitor (APM) units and sends it across to the APU where the data is received by the perfapm-client library and then visualized on a plotted graph.
  • Create a new Vitis workspace.

    Code Block
    languagebash
    themeMidnight
    % cd $TRD_HOME/workspaces/ws_perfapm-server
    % vitis -workspace . &


  • Click 'Import Project' from the welcome screen, Choose 'Eclipse workspace' and select next.

  • Uncheck 'copy projects into workspace', browse to the current working directory and make sure the perfapm, perfapm-server, and perfapm-server_system are selected. Click 'Finish'.
  • Double click on 'perfapm-server_system.sprj' and close the dialog box for platform.

  • Choose 'Create from hardware specification (XSA)' and browse to the xsa file in the 'hwfile' directory of 'ws_heartbeat workspace',
  • Select operating system as 'standalone' and processor as 'psu_cortexr5_1' and click Finish.

  • Copy the generated perfapm-server executable to the dm4 SD card directory.

    Code Block
    themeMidnight
    % mkdir -p $TRD_HOME/sd_card/dm4
    % cp perfapm-server/Debug/perfapm-server.elf $TRD_HOME/sd_card/dm4/


Perfapm-client-test Application (optional step)


The perfapm-client-test application receives performance counter values from RPU-1 and prints them to UART-0. It is by default built as part of the meta-user layer of the PetaLinux BSP. The corresponding yocto recipe and source files are located at $TRD_HOME/petalinux/bsp/project-spec/meta-user/recipes-apps/perfapm-client and the generated binary is located at /usr/bin/perfapm-client-test on the target rootfs.
