Not seeing this take effect in the staging run that's currently got jobs in my lab: https://lava.sirena.org.uk/scheduler/job/1283336/definition - not sure what's going on there? |

Let's try to test it again on staging. I remember last time i tried and failed, but we should try again. |

Currently the kselftest LAVA jobs that KernelCI generates have the test job download the kselftest tarball onto the device. This has a couple of disadvantages: - Any caching that is configured for the LAVA worker will be bypassed, increasing network traffic both for the lab and for the KernelCI storage server. - The entire kselftest tarball has to be downloaded onto the test system, and if (as is usual) it is a NFS filesystem then an uncompressed copy written over the network to the LAVA worker. The test-definitions integration for kselftest also supports running a copy that is already installed in the filesystem, and LAVA supports adding files onto the root filesystem via it's overlay mechanism, so we can avoid the overheads of downloading directly to the device by having LAVA apply the kselftest tarball to the root filesystem as an overlay instead. A commit was previously merged doing this for the legacy LAVA templates, this updates the Maestro ones. Signed-off-by: Mark Brown <broonie@kernel.org>

There was a problem hiding this comment.
as of now on base fastboot we are using buildroot ramdisk which don't have kselftest deps. That's why I push #2969.
