The TuxRun project (www.tuxrun.org) uses QEMU to run tests on a wide variety of kernel configurations on wide range of our emulated platforms. They publish a known good set of images at: https://storage.tuxboot.com/ to help with bisecting regressions in either the kernel, firmware or QEMU itself. The tests are pretty lightweight as they contain just a kernel with a minimal rootfs which boots a lot faster than most of the distros. In time they might be persuaded to version their known good baselines and we can then enable proper checksums. For a couple of tests we currently skip: - mips64, a regression against previous stable release - sh4, very unstable with intermittent oops Total run time: 340s (default) -> 890s (debug) Overall coverage rate (tested targets + disabled tests): lines......: 16.1% (126894 of 789848 lines) functions..: 20.6% (15954 of 77489 functions) branches...: 9.3% (40727 of 439365 branches) Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Cc: Anders Roxell <anders.roxell@linaro.org> Acked-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20230228190653.1602033-11-alex.bennee@linaro.org>
