Indeed and also on irc.oftc.net on #kdevops too if you prefer IRC. But discord seems to be more happening for kdevops these days. > TESTING: > -------------- > The most challenging part of running fstests with kdevops is > establishing the baseline (which tests pass in current 6.1.y per xfs config), > but the baseline for that has already been established and committed > in kdevops repo. > > There is a little quirk, that the baseline is associated only with exact > kernel version, hence commits like: > * c4e3de1 bootlinux: add expunge link for v6.1.39 Indeed so our latest baseline is in workflows/fstests/expunges/6.1.39/xfs/unassigned/ > Make sure that you test your patches against one of those tags > or add new symlinks to other tags. > Start by running a sanity test without your patches, because different > running environments and kdevops configs may disagree on the baseline. You want to first run at least one loop to confirm your setup is fine and that you don't find any other failures other than the ones above. > You can use kdevops to either run local VMs with libvirt or launch > cloud VMs with terraform - you need to configure this and more > during the 'make menuconfig' step. > Attaching my kdevops config (for libvirt guests) as a reference. Please read: https://github.com/linux-kdevops/kdevops https://github.com/linux-kdevops/kdevops/blob/master/docs/requirements.md https://github.com/linux-kdevops/kdevops/blob/master/docs/kdevops-first-run.md https://github.com/linux-kdevops/kdevops/blob/master/docs/kdevops-mirror.md And the video demonstrations. Then I'm happy to schedule some time to cover anything the docs didn't cover, in particular to help you test new patches you wish to backport for a stable kernel and the testing criteria for that.
