Thank you, Jiri, for your feedback. I've dropped this patch from DC v.3.2.297. We will follow-up on this separately and merge it after you do confirm the
issue you reported is fixed.
The patch is all fine and very welcome to be upstream as soon as possible. With this patch, it works as expected.
But the process is broken. Your and Fangzhi Zuo's send-email setup to the least.
BTW you write in the commit log: Fixes: 4b6564cb120c ("drm/amd/display: Fix MST BW calculation Regression")
But: $ git show 4b6564cb120c fatal: ambiguous argument '4b6564cb120c': unknown revision or path not in the working tree.
Instead, it is: commit 338567d17627064dba63cf063459605e782f71d2 Author: Fangzhi Zuo Jerry.Zuo@amd.com Date: Mon Jul 29 10:23:03 2024 -0400
drm/amd/display: Fix MST BW calculation RegressionSo apparently, someone in the process rebases the tree or something. Which is another breakage (non-reliable SHAs).
thanks,
