Дмитрий, пожалуйста предоставьте дополнительную информацию. uname -r dmesg | grep -E 'hdmi|gpu|drm|codec' What brand of monitor and its resolution are used? My samsung 2k monitor cannot be detected by some linux kernels, for example. Although other users noted good performance at 1920x1080 resolution.

@robertoj Please check the kernel configuration on the working version. And which modules are present. Then compare with the non-working option.

Do we need this one?

There are no changes in the driver between kernel versions 6.10 and 6.12. I think this patch can be added to the current (6.12) kernel. In your opinion, what else can be added or which parts should I pay special attention to?

patch/kernel/archive/sunxi-6.1 It will be deleted tomorrow. patch/kernel/archive/sunxi-6.6 This is frozen on version v6.6.75 as stable. It will be moved to LEGACY tomorrow and will no longer be supported.

@Stephen Craig For kernel 6.13, I had to make these changes:

This indicates that the hardware decoding is not working properly. It is very strange that this driver is writing a message. There is no compatible sun50i-h616 line in it. That's my doubt.

But will the system installed from the package work? I can't verify it. The internet is not working on my board. In other words. If you just install the necessary packages.

It seems to me that everything is more complicated. I found this option: https://patchwork.kernel.org/project/linux-clk/patch/20241023075917.186835-6-ryan@testtoast.com/ I'll try to use it. It is marked as not applicable and sent to the archive. I meant the video codec. [ 11.669847] sunxi_cedrus: module is from the staging directory, the quality is unknown, you have been warned. [ 11.672804] cedrus 1c0e000.video-codec: Device registered as /dev/video0 If you try to watch a movie in a video player.

Maybe that's the problem: sound/soc/sunxi/sun4i-i2s.c#L1647

GNOME also works well. XFCE is lame at scaling the screen. For a 1:1 ratio, the letters are large, as if the resolution is set to be less than the actual 2560х1440. Violation of the synchronization frequency. The driver is doing something wrong. Is video hardware decoding working on your device?

The driver is present. You can test this by downloading the packages from the link above.
