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

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We have a repo but it's outdated.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.

@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.

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

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:

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.
