Testing using TuxSuite to build the Linux kernel with LLVM under CI.

All test parameters are encoded in generator.yml; new trees, architectures, configs, etc. should be added there.

Usage

The tuxsuite and github actions workflow configs should be updated when generator.yml changes. Ex.

$ BRANCH=next
$ ./generate_tuxsuite.py $BRANCH
$ ./generate_workflow.py $BRANCH

The generate.py script will run this for you based on the trees that are fed to it. Ex.

# Generate just next and mainline TuxSuite and GitHub Action workflows
$ ./generate.py next mainline

# Regenerate all of the current TuxSuite and GitHub Action workflows
$ ./generate.py

The CI the child workflows run can be rerun locally via:

$ ARCH=arm CONFIG=defconfig LLVM_VERSION=[12|11] [BOOT=0] [INSTALL_DEPS=1] \
  ./check_logs.py

Where ARCH and CONFIG are canonical names from the Linux kernel sources, but should be listed in generator.yml. LLVM_VERSION is which version of LLVM to test. BOOT=0 can be specified to skip the boot test (for instance, when boot failure is expected). INSTALL_DEPS=1 can be specified to install the child workflow dependcies (mostly QEMU) which the github actions workers need to do.

Requires that a TuxSuite secret token is configured.
