My #CI hack can do kernel CI in any possible runner: https://gitlab.com/jarkkojs/linux-tpmdd-test
It builds #BuildRoot environment and runs tests inside it. Probably this something more infrastructural, dunno have not checked :-)
I.e.
git clone https://gitlab.com/jarkkojs/linux-tpmdd-test.git
cd linux-tpmdd-test
cmake -Bbuild && make -Cbuild buildroot-prepare
make -Cbuild/buildroot/build
build/buildroot/build/images/run-tests.sh
It uses TCL’s (in)famous expect to check the output and uses socat and UNIX socket for communications with appropriate QEMU options. And yeah it supports also TPM chips so can be made to boot up modern #systemd installation (have not done so but might in future).
Runner’s ISA does not matter as everything is built up from ground, including toolchain so supports both x86 and ARM although the build itself is x86 ATM. Essentially it can run tests exactly how I would run them on desktop.
