[SOLVED] Using amdgpu on southern island mullins card /wanna vulkan Overwatch

EDIT: DUH stupid me, it is a Sea Island card, Mullins is! So amdgpu.cik_support=1 works! I have amdgpu now! Jeesh.


I am trying to get amdgpu to work on my southern island GCN1.0 mullins card, but it wont load it at boot. I’ve followed these instructions:

ArchWiki on amdgpu for southern island

My specs are

CPU: A8 2.3ghz quadcore


Video: Radeon R5 M240 with 1gb "dedicated VRAM" AKA southern island "Mullins" GCN1.0

I am currently using the radeon driver, which works fine (actually very well - I have vdpau and most other relevant packages installed, and glxinfo tells me I have OpenGL core profile 4.5 working). I have the amdpgu driver installed as well. I use the stock ARCH kernel 4.18.

But when I add amdgpu.si_support=1 radeon.si_support=0 to kernel at boot in grub, it freaks out and dumps me in a terminal with some flickering. The dmesg from when that happens is in this pastebin:


I can’t really see where it rejects the amdgpu driver?

Edit: btw a friend noticed that there is a traceback if you have any ideas about that:
[ 9.946881] sysfs: cannot create duplicate filename ‘/class/power_supply/ACAD’
[ 9.946886] CPU: 0 PID: 258 Comm: systemd-udevd Not tainted 4.18.8-arch1-1-ARCH #1

[ 9.946889] Call Trace:
and then below that.

I read somehwere that I should remove 20-radeon.conf and/or replace it with 20-amdgpu.conf - should I try that?

Why do I want the amdgpu driver instead of the radeon, since radeon works fine? I want to use vulkan to play Overwatch in Lutris, since it does a fancy gpu-hang when I shoot rockets with D.Va and other sparkly effects play on radeon driver - and perhaps using amdgpu with DXVK will be better in that scenario. Using the radeon driver the video freezes when playing, and this is dmesg (pastebin) from tty2.

Do you currently have one of the above mentioned files?

You may have to blacklist the driver you don’t want to use to stop the kernel from loading it. You might also want to look into whether you want the catalyst driver, I’m not sure which is better of why, not much experience with AMD and linux drivers sorry.

Have you read through the following wiki page a few times? https://wiki.archlinux.org/index.php/AMDGPU

You can see from around line 900 of your dmesg output linked above that the radeon driver is being loaded and you likely need to either remove it, blacklist it, or follow the wiki on enabling KMS for early kernel mode setting on that module.

Hey thanks for your reply!

Sounds reasonable, feels scary to remove it totally, but I thought I did blacklist it by booting with radeon.si_support=0 amdgpu.si_support=1 but that might not be enough then.

Aha, I did this: MODULES=(amdgpu radeon) , but not this: # mkinitcpio -p linux <- so, that should help!

If it doesent, I’ll try blacklisting.

It said I need the very latest linux-firmware, but just normally keeping up with updates should mean I have that right?

EDIT: DUH stupid me, it is a Sea Island card, Mullins is! So amdgpu.cik_support=1 works! I have amdgpu now! Jeesh.
