Why does doing this in fixture help? I noticed that pipe B was failing with other platforms as well, not just with HSW. Bandwidth calculation within fixture fixed the other platforms that was failing as well as my local HSW machine. I think it is unnecessary to calculate bandwidth for older platforms. We have seen these issues only with gen11+. -- Petri Latvala _______________________________________________ igt-dev mailing list igt-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/igt-dev
