This is awaiting moderators' review, after the approval may be the CI would be triggered.

Subject: Re: [PATCH v2] tests/kms_bw: New test for bandwidth validation

For some reason, I don't see this patch in the patchwork and in the
igt-dev mailing list. Did the CI run in this patch? Any idea on what
happened here?

Thanks
Siqueira
