The driver in these kernels works well for "old" 1080p monitors. It has been verified that it does not work with SAMSUNG, LG 2k, 4k resolution models. This problem is in the drivers You can set in the file /boot/armbianEnv.txt verbosity=10. The output of this command in a working and non-working version may possibly suggest which of the driver modules is failing. dmesg | grep -E 'hdmi|drm|gpu|edid|cec'

The possible problem is in the u-boot loader. In order to understand what the problem is, we need a boot log from the UART console.

Please be patient. We are working on it. First of all, it will be added to the EDGE core.

The pwm driver is present there. It is necessary to add the overlay correctly. Is your device an orange-pi-zero-3?

I wrote it in a private message.

This is an outdated core and will no longer be supported after this pull request. Try switching to the EDGE core (6.13). I will add the ability to apply overlays for PWM to the EDGE core. And we will check it together.

variant-1 I didn't check it. Use it at your own risk. P.S. This will not work in the Armbian core at the moment. Further development is required in the sound/soc/sunxi/sun4i-i2s.c driver, with a cursory reading of the source text.

Okay, let's go. First, please describe what you have connected and how. What actions were taken. Any details you deem necessary.

uname -r command. Two types of PWM can be available. Software and hardware. The hardware for h616-h618 processors is only available for these pins: PG19 - pwm1 PH0 - pwm3 PH1 - pwm4 PH2 - pwm2 PH3 - pwm1 PI11 - pwm1 PI12 - pwm2 PI13 - pwm3 PI14 - pwm4 Which pin do you want to use PWM for?

Which pin requires an overlay? Which core are you using?

The GPU issue has been resolved in kernel 6.12 and subsequent versions.

Unfortunately, there's nothing I can do to help you with this core. I suspect that for other monitors the HDMI output will work. Just try to change the monitor, change the OS image to understand where the problem is. Пожалуйста попробуйте работу любого образа Armbian с этой страницы загрузки. https://www.armbian.com/orange-pi-4-lts/ If working on this image will have problems, please create a new theme with a name reflecting the essence of the problem.

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.
