When it does happen, +not much can be done besides waiting it out, or cancel it. + +Due to limited resources, we currently do not run the CI automatically +on every push; instead, we only run it automatically once the MR has +been assigned to ``Marge``, our merge bot. + +If you're interested in the details, the main configuration file is ``.gitlab-ci.yml``, +and it references a number of other files in ``.gitlab-ci/``. + +If the GitLab CI doesn't seem to be running on your fork (or MRs, as they run +in the context of your fork), you should check the "Settings" of your fork. +Under "CI / CD" → "General pipelines", make sure "Custom CI config path" is +empty (or set to the default ``.gitlab-ci.yml``), and that the +"Public pipelines" box is checked. + +If you're having issues with the GitLab CI, your best bet is to ask +about it on ``#freedesktop`` on Freenode and tag `Daniel Stone +`__ (``daniels`` on IRC) or +`Eric Anholt `__ (``anholt`` on +IRC). + + +Intel CI +-------- + +The Intel CI is not yet integrated into the GitLab CI. +For now, special access must be manually given (file a issue in +`the Intel CI configuration repo `__ +if you think you or Mesa would benefit from you having access to the Intel CI). +Results can be seen on `mesa-ci.01.org `__ +if you are *not* an Intel employee, but if you are you +can access a better interface on +`mesa-ci-results.jf.intel.com `__. + +The Intel CI runs a much larger array of tests, on a number of generations +of Intel hardware and on multiple platforms (x11, wayland, drm & android), +with the purpose of detecting regressions. +Tests include +`Crucible `__, +`VK-GL-CTS `__, +`dEQP `__, +`Piglit `__, +`Skia `__, +`VkRunner `__, +`WebGL `__, +and a few other tools. +A typical run takes between 30 minutes and an hour. + +If you're having issues with the Intel CI, your best bet is to ask about +it on ``#dri-devel`` on Freenode and tag `Clayton Craft +`__ (``craftyguy`` on IRC) or +`Nico Cortes `__ (``ngcortes`` +on IRC). diff --git a/docs/contents.rst b/docs/contents.rst index 0e42f50780b..c1cedf56fed 100644 --- a/docs/contents.rst +++ b/docs/contents.rst @@ -63,6 +63,7 @@ devinfo codingstyle submittingpatches + ci releasing release-calendar sourcedocs
