> [Impact]
>
> Monitors black out when an external one connects via thunderbolt3 on AMD Ryzen
> 9 PRO 7940HS w/ Radeon 780M Graphics.
>
> [Fix]
>
> This can be fixed by upstream linux-firmware commit 253cc179d849 ("amdgpu:
> Update DMCUB for DCN314 & Yellow Carp").
>
> However, in linux-firmware/lunar and jammy, the commit history related to the
> files to be updated often associated with many other more, they're now updated
> with overwrites without cherry-pick ancestor commits along the history.
>
> For linux-firmware/mantic, a simple cherry-pick would do.
>
> [Test Case]
>
> Connect an tbt3 featured external monitor (ASUS PA27AC) after boot to GUI.
> Check if both the built-in and external monitors lights up as usual.
>
> [Where problems could occur]
>
> Update amdgpu firmware are error prone, verified on targeting series as
> possible.
>
> [Other Info]
>
> While this affects linux-oem-6.1/jammy, as well as linux/lunar kernels, Jammy
> and Lunar are nominated for fix.
