What is Firmware Test Suite (FWTS)?

  • The recommended ACPI SCT
  • An open-source Linux tool that automates

firmware checking

  • A good choice if one wants to

implement new tests for specific features

Using FWTS – Command Line

  • Run a single test, ex. C states

– sudo fwts cpufreq

  • Run multiple tests, ex. C states + PCIe ASPM

– sudo fwts cpufreq aspm

  • Run all ACPI tests + all UEFI tests

– sudo fwts --acpitests --uefitests

  • View all tests

– fwts --show-tests-full

Submitting Patches

UEFI Plugfest – October 2017 www.uefi.org 25

Send patches by Git Generate patches by Git

Header Signed-off

(Implement fwts-test tests)

Check Coding Styles (Linux Kernel) Function brackets Spaces & tabs Line length(?)

Write Some Code

Add a new test Fix a bug

Why Contribute to FWTS?

  • Framework is easy to add new features,
  • ex. Device Tree
  • Existing code is available, ex. ARM’s

Server Base Boot Requirements (SBBR)

  • Example: an imaginary Linux-Only-Spec

that must exclude all Windows features

–No DBGP, DBG2, MSDM, and SLIC etc…

FWTS License & FWTS Community

UEFI Plugfest – October 2017 www.uefi.org 27

slide-28
SLIDE 28

License – GPLv2

  • FWTS uses GPLv2 license

– A “Copy-Left” license

  • Can-do & can’t-do
  • Should I upstream my code?

– It depends, but it is recommended

  • Must I open-source my code?

– Unless you release the binary, the answer is usually No – But maintenance gets difficult as FWTS grows
