TuxSuite, by Linaro, is a suite of tools and services to help with Linux kernel development. The TuxSuite CLI (this repo) is the supported interface to TuxBuild and TuxTest.

tuxsuite screencast

To request access, email us at or fill out our access request form.


The TuxSuite CLI supports two services: TuxBuild and TuxTest.


TuxBuild Logo

TuxBuild is an on demand API for building massive quantities of Linux kernels in parallel. It is used at scale in production by LKFT and ClangBuiltLinux as well as many individual Linux kernel engineers.

TuxBuild is accessed by running tuxsuite build and tuxsuite build-set.


TuxTest Logo

TuxTest is an on demand API for testing Linux kernels reliably and quickly. It is currently in Beta phase and is already available to TuxBuild users.

Install and Configure

Install using pip

TuxSuite requires Python version 3.6 or greater, and is available using pip.

To install tuxsuite on your system globally:

sudo pip3 install -U tuxsuite

To install tuxsuite to your home directory at ~/.local/bin:

pip3 install -U --user tuxsuite

To upgrade tuxsuite to the latest version, run the same command you ran to install it.

Install using docker

tuxsuite is also available as a docker container at tuxsuite/tuxsuite.

For example, to run tuxsuite via docker:

docker run tuxsuite/tuxsuite tuxsuite build --help

Setup Config

The Authentication token needs to be stored in ~/.config/tuxsuite/config.ini. The minimal format of the ini file is given below:

$ cat ~/.config/tuxsuite/config.ini

Alternatively, the TUXSUITE_TOKEN environment variable may be provided.

If you do not have a tuxsuite token, please reach out to us at


tuxsuite build

Submit a build request using the tuxsuite command line interface. This will wait for the build to complete before returning by default.

tuxsuite build --git-repo '' --git-ref master --target-arch arm64 --kconfig defconfig --toolchain gcc-9

tuxsuite build-set

Create a tuxsuite config file with a basic set of build combinations defined.

cat <<EOF > basic.yaml
  - name: basic
      - {target_arch: arm,    toolchain: gcc-9,    kconfig: multi_v7_defconfig}
      - {target_arch: arm,    toolchain: gcc-10,   kconfig: multi_v7_defconfig}
      - {target_arch: arm,    toolchain: clang-10, kconfig: multi_v7_defconfig}
      - {target_arch: arm64,  toolchain: gcc-9,    kconfig: defconfig}
      - {target_arch: arm64,  toolchain: gcc-10,   kconfig: defconfig}
      - {target_arch: arm64,  toolchain: clang-10, kconfig: defconfig}
      - {target_arch: i386,   toolchain: gcc-9,    kconfig: defconfig}
      - {target_arch: i386,   toolchain: gcc-10,   kconfig: defconfig}
      - {target_arch: x86_64, toolchain: gcc-9,    kconfig: defconfig}
      - {target_arch: x86_64, toolchain: gcc-10,   kconfig: defconfig}
      - {target_arch: x86_64, toolchain: clang-10, kconfig: defconfig}
      - {target_arch: arc,    toolchain: gcc-10,   kconfig: hsdk_defconfig}
      - {target_arch: riscv,  toolchain: gcc-10,   kconfig: defconfig}
      - {target_arch: mips,   toolchain: gcc-10,   kconfig: ci20_defconfig}
# Build the build set defined in the config file named 'basic.yaml'
tuxsuite build-set --git-repo '' --git-ref master --tux-config basic.yaml --set-name basic

All the parameters can be specified in the build-set itself and invoke tuxsuite tuxsuite build-set --tux-config <basic>.yaml --set-name <set-name>

tuxsuite plan

Submit a plan request using the tuxsuite command line interface. The plan file describes the list of builds along with the tests to run for each successful build. When one build is finished, the corresponding test is automatically started.

Create a plan configuration file:

version: 1
name: kernel validation
description: Build and test linux kernel with every toolchains

  - {toolchain: gcc-8, target_arch: arm64, kconfig: defconfig}

  - {toolchain: gcc-10, target_arch: arm64, kconfig: defconfig}
  - {toolchain: clang-10, target_arch: arm64, kconfig: defconfig}
  - {toolchain: clang-11, target_arch: arm64, kconfig: defconfig}
  - {toolchain: clang-12, target_arch: arm64, kconfig: defconfig}
  - {toolchain: clang-13, target_arch: arm64, kconfig: defconfig}

- builds:
  - {toolchain: gcc-8, target_arch: x86_64, kconfig: defconfig}
  - {toolchain: gcc-9, target_arch: x86_64, kconfig: defconfig}
  - {toolchain: gcc-10, target_arch: x86_64, kconfig: defconfig}

  test: {device: qemu-x86_64, tests: [ltp-smoke]}

Submit the plan with:

tuxsuite plan --git-repo --git-ref master plan.yaml

tuxsuite test

Submit a test request using the tuxsuite command line interface. This will wait for the test to complete before returning.

tuxsuite test --device qemu-x86_64 --kernel --tests ltp-smoke

tuxsuite results

The results sub-command provide a way to get the status of a build/test/plan that has been previously submitted.

The results sub-command when invoked without any arguments shows the latest builds, tests, and plans that have been previously submitted by the user.

tuxsuite results

The build option fetches the results of the build based on the given uid

tuxsuite results --build 1t26TJROt6zoxIw3YS2OlMXMGzK

The test option fetches the results of the test based on the given uid

tuxsuite results --test 1s20dnMkE94e3BHW8pEbOWuyL6z

tuxsuite results --plan 1t2UxTeU15WDwvhloPFUqjmr3CX

Projects and Developers using tuxsuite

  • LKFT - Linaro's Linux Kernel Functional Testing uses tuxsuite with gitlab-ci to continuously build upstream Linux kernels. The kernels are then functionally tested on a variety of hardware using LAVA.
  • ClangBuiltLinux uses TuxBuild to validate hundreds of combinations of Linux kernels and LLVM environments.
  • Lee Jones uses a GitLab CI pipeline to validate his 3.18 kernel maintainership. The gitlab pipeline, tuxsuite config, and documenting its setup are defined in the kernel-pipeline repository.

Community and Support

The TuxSuite team may be engaged through chat, email, or gitlab issues.

To chat with us, join our public Discord, or our IRC channels #tuxsuite and #tuxmake on Libera Chat.
