tuxmake 1.40.0

Thin wrapper to build Linux kernels

Documentation - Repository - Issues

TuxMake, by Linaro, is a command line tool and Python library that provides portable and repeatable Linux kernel builds across a variety of architectures, toolchains, kernel configurations, and make targets. TuxMake is a part of TuxSuite, a suite of tools and services to help with Linux kernel development.

About TuxMake

Building Linux is easy, right? You just run "make defconfig; make"!

It gets complicated when you want to support the following combinations:

• Architectures (arc, arm, arm64, i386, mips, parisc, powerpc, riscv, s390, sh, sparc, x86_64, etc)
• Toolchains (gcc-8, gcc-9, gcc-10, clang-10, clang-11, clang-nightly, etc)
• Configurations (defconfig, distro configs, allmodconfigs, randconfig, etc)
• Targets (kernel image, documentation, selftests, perf, cpupower, etc)
• Build-time validation (coccinelle, sparse checker, etc)

Each of those items requires specific configuration, and supporting all combinations is difficult. TuxMake seeks to simplify Linux kernel building by providing a consistent command line interface to each of those combinations listed above. You specify what to build at the command line, and TuxMake drives the build for you, doing the same steps the same way every time.

The real power comes from using TuxMake's curated, portable build environments distributed as Docker/Podman container images. When using these versioned and hermetic filesystem images, your team can use the same exact toolchain(s) across different workstation platforms. Reporting and reproducing build failures is trivial by sharing TuxMake command lines with others.

Installing TuxMake

There are several options for installing TuxMake:

• From PyPI
• Debian packages
• RPM packages
• Run uninstalled

Using TuxMake

To use TuxMake, navigate to a Linux source tree (where you might usually run make), and run tuxmake. By default, it will perform a defconfig build on your native architecture, using a default compiler (gcc).

The behavior of the build can be modified with command-line arguments. Run tuxmake --help to see all command-line arguments.

Examples

Build from current directory:

$ tuxmake

Build using Podman:

$ tuxmake --runtime podman

Build from specific directory:

$ tuxmake --directory /path/to/linux

Build an arm64 kernel:

$ tuxmake --target-arch=arm64

Build an arm64 kernel with gcc-10:

$ tuxmake --target-arch=arm64 --toolchain=gcc-10

Build an arm64 kernel with clang-10:

$ tuxmake --target-arch=arm64 --toolchain=clang-10

Build tinyconfig on arm64 with gcc-9:

$ tuxmake -a arm64 -t gcc-9 -k tinyconfig

Build defconfig with additional config from file:

$ tuxmake --kconfig-add /path/to/my.config

Build defconfig with additional config from URL:

$ tuxmake --kconfig-add https://foo.com/my.config

Build defconfig with additional in-tree config:

$ tuxmake --kconfig-add kvm_guest.config

Build defconfig with additional inline config:

$ tuxmake --kconfig-add CONFIG_KVM_GUEST=y

Build tinyconfig on arm64 with gcc-9 using docker:

$ tuxmake -r docker -a arm64 -t gcc-9 -k tinyconfig

Build DTBs on arm64 using podman:

$ tuxmake -r podman -a arm64 -t gcc-9 dtbs

Incremental builds can be done by reusing a build directory:

$ tuxmake --build-dir=/path/to/output
# hack on source ...
$ tuxmake --build-dir=/path/to/output
# only rebuilds what is needed

Using configuration files:

# reads command line options from ~/.config/tuxmake/myconfig
$ tuxmake @myconfig
# reads command line options from /tmp/myconfig
$ tuxmake @/tmp/myconfig

Display all options:

$ tuxmake --help
