Hi Arvind,

Would you mind to test your patchset with drm-ci ? There is a amdgpu
test there and I would love to get your feedback of the ci.

You basically just need to apply the ci patch which is available on
https://cgit.freedesktop.org/drm/drm/log/?h=topic/drm-ci

There are instruction on the docs, but in short: to configure it, you push
your branch to gitlab.freedesktop.org, go to the settings and change the
CI/CD configuration file from .gitlab-ci.yml to drivers/gpu/drm/ci/gitlab-ci.yml,
and you can trigger a pipeline on your branch to get tests running.

(by the time of this writing, gitlab.fdo is under maintenance but should
be up soonish).

Thank you!
Helen
