Getting AMDGPU to work on Ryzen 5 2400G + B350

[n00b]

Hi everyone,

For about a month I have been trying to get my workstation to boot with amdgpu without success. I am on Fedora 27/28. I am a bit desperate by now.

With amdgpu, the boot keeps hanging or boots with a corrupted display. So far I have been able to boot only with nomodeset. I tried several 4.15+ kernels without any success (up to 4.15.10). After learning 4.16 has more complete support, I upgraded to Fedora 28 beta release, but that hasn't helped either. Then I tried booting with amdgpu.dc=1, the only improvement was the screen corruption was reduced but was still unusable (it went from 1/4 of the screen to 1/2 of the screen being rendered correctly). The mouse pointer movement also seems sluggish.

I have filed a Fedora bug report (bug #1548961), but I'm unable to add any useful information other than my hardware configuration, and screenshots.

Hardware: Ryzen 5 2400G + Gigabyte AB350M Gaming 3
Distro: Fedora 28 (beta)
Kernels: 4.16.0-0.rc5.git0.2.fc28.x86_64, 4.16.0-0.rc4.git0.1.fc28.x86_64

If someone could suggest something, that would really great.

Make sure the following are set in the .config for your kernel:
CONFIG_DRM_AMD_DC=y
CONFIG_DRM_AMD_DC_DCN1_0=y

You can also try our latest staging kernel:

I hope that you dont mind that I am "hijacking" this thread but the OP is in a very similiar situation, maybe this can help him too.

I am in the same situation, apart that I am using Debian 9. B350 chipset on an Asus b350-prime board and a ryzen 3 2200G.
I am even unsure if I am picking the proper kernel source from ~agd5f/linux by using:
git clone -b amd-staging-drm-next git://people.freedesktop.org/~agd5f/linux
uanme states it is 4.16.0-rc1-custom

During boot, I get bunch of error messages regarding ACPI failures and the CPU getting into rcu_shed self-detected stall followed up by:
Fatal error during GPU init
Failed to load gpu_info firmware "amdgpu/raven_gpu_info.bin" though it resides in /lib/firmware/amdgpu and set int the kernel menuconfig.

Besides that I am using standard debian stable packages. It would be really helpful if someone could post a guide to make the new ryzens work with Debian, there is so much information out there very hard to cope with as a novice user.

@debianxfce:
Your distribution looks promising - is it usable like Debian stable - I mean does it use the debian mirrors for package updating ? I really consider giving it a try. But foremost, some howto would be really great.

I'm actually using this kernel. Most DC/DCN related patches have improved the perceived stability of the system.

I have a Ryzen 5 2400G + MSI B350 Tomahawk

Make sure the following are set in the .config for your kernel:
CONFIG_DRM_AMD_DC=y
CONFIG_DRM_AMD_DC_DCN1_0=y

I don't know how I can confirm that from a running system, so I looked up the F28 kernel package source repo. They seem to have those set: CONFIG_DRM_AMD_DC, CONFIG_DRM_AMD_DC_DCN1_0.

When I boot with amdgpu I can see DC is set to auto (thankfully I can get to a terminal despite the screen corruption):

# systool -v -m amdgpu | grep dc
    dc                  = "-1"
    dc_log              = "0"

So I turned on logging for DC with amdgpu.dc_log=1. After doing so, I see tracebacks from amdgpu in my journal:

You can find the more detailed journal (with unrelated messages deleted) on pastebin. Please note, Fedora released a newer kernel (rc6) in the testing repo, I'm running this now.

You can also try our latest staging kernel:
https://cgit.freedesktop.org/~agd5f/...aging-drm-next

I have never compiled upstream kernels, it will require a bit of effort on my part to try this route.

You can try my distribution: https://www.youtube.com/watch?v=fKJ-IatUfis

Looks interesting . But I have been a Fedora user for almost 10 years, switching distros on my primary workstation would be too disruptive for me. Thanks a lot for the response.

@debianxfce:
Is there a place to report bugs with your distribution, because I have run into 2 problems.
1) If running in non UEFI mode, the screen gets heavily distorted and is unusable after chosing graphical/install
2) In UEFI mode it seems to run fine, but it does not allow to manually run partitioning. If I chose manual, it just refreshes the page and does not load the partition program, so I get stuck there

[tw78]

The installer uses entire disk. You can install it to a fast usb stick.

I have installed it on an USB stick and then later moved the whole partition to a free space on my SSD. At first boot I had graphic glitches, but on the second boot after doing an apt-get dist-upgrade, it works like a charm. Impressive, thanks.

[tw78]

Maybe you could also consider including dm-crypt in the next kernel release you are doing. I still get a small CPU sleep due to rcu_shed during boot. Besides that, I can declare it working for my combination: Ryzen 3 2200G on an Asus Prime B350-Plus board.

[blisbell]

Any ideas how to fix this with kernel configuration? Ryzen 5 1600 needs it.

The kernel needs this patch and this line in grub GRUB_CMDLINE_LINUX_DEFAULT="rcu_nocbs=0-11 mem_encrypt=off"
This explains the rcu_nocbs comand https://lime-technology.com/forums/t...ryzen-freezes/

https://github.com/graysky2/kernel_gcc_patch

This is the patch needed just save as enable_additional_cpu_optimizations_for_gcc_v4.9%2 B_kernel_v4.13%2B.patch or change the extension. if you have ryzen 7 change the 11 to 15 ryzen 3 to 3,I have a ryzen 5 an this works for me.
