Missing information about exact kernel patches for Stoneyridge devices.

[GamePlayer-8]

Good evening,

I've got a problem with getting an exact information about what patches should be applied on the Linux kernel 6.1+ for Stoneyridge Chromebook devices.

The documentation of Known issues in the Stoneyridge devices section says:

Needs kernel compiled with AMDGPU=Y instead of =M and firmware built-in to get working audio

eMMC is only detected on a cold boot unless you have a patched kernel

although not linking any source to the patches for the Linux kernel as mentioned.

What patches should I use?

---

Additionally while reading dmesg for anything related to the problem of eMMC I've got:

[    0.000000] efi: EFI v2.7 by EDK II
[    0.000000] efi: SMBIOS=0xbf41a000 SMBIOS 3.0=0xbf418000 ACPI=0xbf533000 ACPI 2.0=0xbf533014 MEMATTR=0xbbf16c18 
[    0.000000] efi: Remove mem97: MMIO range=[0xffbc0000-0xffbfffff] (0MB) from e820 map

[WeirdTreeThing]

I can add detailed info about stoney. The emmc issue is due to an update in the driver, which we have a patch for.

[GamePlayer-8]

Thank you. By the way, is there a gist / repo of the patch already? I'm configuring the PKGBUILD for the kernel right now.

[WeirdTreeThing]

We have a repo but it's outdated. The person that is working on updating it will push the changes and make a pr sometime soon.

[GamePlayer-8]

link?

@WeirdTreeThing I've patched the kernel for my system (source code).

Although CONFIG_DRM_AMDGPU=y causes the kernel to freeze the screen, on the Stoneyridge device.
The rest of the system components (NetworkManager, sddm) is being loaded like nothing happened.

[WeirdTreeThing]

You also need to build the AMDGPU firmware into the kernel.

[GamePlayer-8]

After a lot of troubleshooting, I have embeded the /lib/firmware/amdgpu/stoney* firmware into my kernel.

Although even if speakers / jack output is being recognized, there's no sound being played. A microphone is being shown, but there's a loud noise.

Camera isn't being recognized too. What might be the issue?

aplay error when trying to play sound to the soundcard provided by stoney* firmware:

[WeirdTreeThing]

6.5 is known to have issues, I just kinda reverted a few things until it worked.

[GamePlayer-8]

Should I recompile under 6.1 kernel?

[WeirdTreeThing]

Try that, afaik it should work until we figure out what broke 6.5.

[GamePlayer-8]

Your emmc.patch file works only under 6.4+ kernel versions. I'll try to compile under 6.4.16.

[GamePlayer-8]

Under 6.4.16 audio output works. Still Camera is unrecognized by the kernel and built-in microphone isn't working.

[WeirdTreeThing]

The camera is just usb so it's likely to be a hardware issue.

[GamePlayer-8]

What to do about microphone?

dmesg reports:

[ 4754.381512] acp3x-alc5682-max98357 AMDI5682:00: DMIC gpio failed err=-2

[GamePlayer-8]

Problem with the webcam was reported before to the MrChromebox, but the issue got refused.

[WeirdTreeThing]

That is not a real issue, that's a separate driver that loads automatically even though it isn't used on this platform.

[GamePlayer-8]

How to deal with it?

[WeirdTreeThing]

Ignore it or blacklist the module.

[GamePlayer-8]

Which one should I blacklist exactly?

[WeirdTreeThing]

I don't remember off the top of my head, look for acp3x in lsmod.

[WeirdTreeThing]

MrChromebox 4.21.1 firmware has released today, which fixes emmc on warm reboots on the firmware side. The kernel patch is no longer needed.

[GamePlayer-8]

I don't remember off the top of my head, look for acp3x in lsmod.

lsmod doesn't show any type of acp3x module loaded. The nearest one might be snd_soc_acp_rt5682_mach what's being used for the audio ports / speakers.

[WeirdTreeThing]

I just checked on my careena and yeah that's the one you need to blacklist.

[GamePlayer-8]

I've blacklisted and still no change in the Webcam detection.

modprobe loaded snd_soc_acp_da7219mx98357_mach - even after blacklisting this one too, there's no audio device detected.

[WeirdTreeThing]

snd_soc_acp_da7219mx98357_mach is the one that's supposed to load. Blacklisting snd_soc_acp_rt5682_mach on my careena didn't break audio.

[GamePlayer-8]

Yeah, I meant, on both modules camera doesn't work

[WeirdTreeThing]

Camera is not part of audio. Check for your camera in lsusb.

The usb device for your camera is missing. Either something in coreboot is broken or the physical cable is damaged. You can rule out coreboot by testing stock. I can say that on my careena, the camera cable was damaged and only worked at certain angles.

[GamePlayer-8]

Nothing bad happened to my camera when I was using ChromeOS so probably a firmware issue. Will try to compile the original kernel and see the difference.

[WeirdTreeThing]

The kernel isn't gonna prevent usb devices from being detected. You will need to flash stock and verify the camera works there.

[GamePlayer-8]

Works on stock firmware, but only under ChromeOS.

[WeirdTreeThing]

but only under ChromeOS

As in you tried to boot a mainline distro on stock firmware?

[GamePlayer-8]

yes

[WeirdTreeThing]

I've never seen anything like this.

[ellyq]

snd_soc_acp_da7219mx98357_mach

This is the correct module for Stoney.

What to do about microphone?

dmesg reports:

[ 4754.381512] acp3x-alc5682-max98357 AMDI5682:00: DMIC gpio failed err=-2

ACP3x == Picasso (Ryzen 3000).

[GamePlayer-8]

ACP3x == Picasso (Ryzen 3000).

What should I do about it?
