tuxbuild (https://gitlab.com/Linaro/tuxbuild) is a new microservice from Linaro for building Linux kernel images. We can build clang kernel images with it via: $ tuxbuild build \ --git-repo https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git \ --git-ref master --target-arch arm64 --kconfig defconfig --toolchain clang-9 to build mainline ARCH=arm64 defconfig with Clang 9. This requires a tuxbuild client installed, and an API key. For example, I have requested 2 API keys; one is in my ~/.config/tuxbuild/config.ini, one is stored in an environmental variable TUXBUILD_TOKEN in https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/settings. See https://gitlab.com/Linaro/tuxbuild#setup-config for more information. This change allows driver.sh to use tuxbuild rather than fetching and building kernel images locally. The above command with driver.sh would look like: $ TUX_BUILD=1 ARCH=arm64 REPO=linux LLVM_VERSION=9 ./driver.sh This change turns on 3 daily builds with tuxbuild; all mainline defconfigs with clang-9, one arm64, one arm32_v7, and on x86_64.
for testing TUX_BUILD=1 builds on travisci.

I am fairly certain Travis will timeout here because there will not be any output for ten minutes. I am not sure how to get around that, we'll have to brain storm (or maybe reach out to Travis support and see if there is any way for that restriction to be waved).

Last time I contacted Travis CI support, they told me there is no way to change the 10-minute silence timeout. The easiest way to get around that restriction is to just print something every 10 minutes.

This should be an array:
cmd=( tuxbuild build --git-repo ${url} --git-ref ${branch:=master} --target-arch ${tux_arch} --kconfig ${config} --toolchain clang-${LLVM_VERSION} )
...

This can be runtime=$((end - start))

I expect the first run to fail; we need to figure out how to ship the
tuxbuildclient in our docker image. Once that's sorted, we can:
