Just to update:
I have been busy with a lot of things, and still now I can’t work on it.
I didn’t forget tho.
Gonna follow those instructions as soon as I can.
@leorize , I’ve managed to run the commands yesterday, but for personal reasons I am making this message just now.
So, here’s the before values:

Here’s a screenshot of the “after alone” of VKcube.
Nothing changed, so uploading the different one is a waste of internet.
Still, for Vulkan it says “LLVMPIPE” and also renders it in Software for games (Quake Remaster goes max 15fps in the menu’s demo and 5 to 7 when in the HUB).
For OpenGL games like Portal_1 it says “KAVERI” and runs at decent, even if poor, performance.
At least, instead of sudo grubby --args=radeon.cik_support=0 --args=amdgpu.cik_support=1 --update-kernel=ALL
please give a try to sudo grubby --args="radeon.si_support=0 amdgpu.si_support=1 radeon.cik_support=0 amdgpu.cik_support=1" --update-kernel=ALL,
it works for me.
After reboot, verify with sudo grubby --info=ALL
The grubby man page confirms that --args accepts a space-separated list of kernel parameters, and using quotes ensures the shell passes them as a single argument.
Quotes: The command uses quotes around the --args value, which is critical to prevent shell misparsing. Without quotes, the shell would interpret the space-separated parameters as separate arguments, causing grubby to fail or apply only the first parameter.
Multiple --args options are not guaranteed to merge correctly in all grubby versions. The man page suggests parameters are combined, but in practice, later --args may overwrite earlier ones or cause parsing issues, depending on the grubby implementation or user error (e.g., running as separate commands).
Looks like I was late to the party and the paste expired already 
If you have a GitHub account, can you post the content as a GitHub Gist instead? That would last forever instead.
Re: inxi -Fzxx values after applying the command, it is interesting that the “Graphics” section disappeared. There might be an issue with your installation, but I can’t diagnose further without the (now expired) logs.
Really funny busyness here.
Does the website even warn that the link expires the third day?
Whatever.
I will try running a Fedora 42 install USB to see if it can run VKcube with Vulkan, but then again, it shouldn’t.
This guy says that “he can just run the R9 390 without issue”.
@leorize , I am gonna open this comment with a recap of the issue from the beginning:
It was Fedora 39; Mesa was 24. Vulkan worked.
Mesa 25 came and Vulkan didn’t work, Software Rendering was so bad that even the desktop would render at 20fps if above 800x600.
A small update came out, stuff seemed fixed, then it either broke again or was never truly fixed.
We come to now. For almost 40 days I was “busy” so just lately I managed to answer back.
Here are the datapoints needed.
I also ran a Live USB of Fedora 42.
Altho MangoHUD’s way to show data seems to be inconsistent on this PC alone (here[1] it literally just says “FPS” instead of “VULKAN” or “VK”, never have I seen that anywhere else) I believe it just means “Vulkan rendered through LLVMPIPE”, which means “Software rendered Vulkan”.
Since I want to avoid doing THIS and I want to understand why and how this stuff isn’t working, I wanna try fix this before doing ^that^.
I love character limits.

Here you can see “Vulkan” is the name given to “what is rendering it”.
[It was just VULKAN with the default MangoHUD settings, but by selecting more stuff I can see it still using LLVMPIPE here, even if everything else seems to at least recognize KAVERI…]
Thanks for the logs.
So from this line:
[ 0.000000] Command line: BOOT_IMAGE=(hd0,gpt2)/vmlinuz-6.16.3-200.fc42.x86_64 root=UUID=7f057b81-3dff-433a-8a84-acceb76fd6b3 ro rootflags=subvol=root rhgb quiet amdgpu.cik_support=1
It appears that radeon.cik_support=0 is missing from the kernel command line, which meant the legacy radeon driver is still controlling your GPU instead of amdgpu.
I’d say to give @josevillani instructions a try and see if the required kernel arguments show up:
Please send logs again after you tried this, thanks!
I’ll try tomorrow.
Still, I don’t like to run things I don’t understand like this for the reasons I gave above.
Regardless, might as well at least try, since nothing important is on that PC.

I’ve been busy today, and right now I am TIRED.
I can’t articulate very well what I want to say, so I’m just gonna drop this here:
Thank you people for the hands given, even if I’d’ve liked a little more info about what these magic spells do.
Now my Kaveri/Godavari iGPU seems to work somewhat better AND to use Vulkan without LLVMPIPE (meaning that it’s not Software Mode).
After using a lot of > " < and wording the sentence appropiately I got Wikipedia’d into a very barebone page which would have been useless without what I barely learn’t here because these things are just not spelled out anywhere.
tl;dr it seems that my hardware is “partially supported” by a software which has been in development for the last 11 years.
I have no reason to close the thread right now. If anything I have a very good reason I should not:
I am very TIRED and should stop think about things right now. It’s 19 hours since I got out of bed.
I have been trying to benchmark some games these last two weeks, but due to poor health and “issues with the computer” it’s not going as smooth as it should.
I just don’t want to not post any update at all on this page, evenmore because W10 support died yesterday, literally.
tl;dr
Both W10 and Fedora KDE are not good-to-perfect experiences because of bugs and strange lacks of support for the monitors’ resolutions.
On W10 it’s WAY easier to set up a custom resolution compared to Wayland[1] but, I am going to be honest, this APU is almost 10 years old and will die soon if anyone were to seriously use this as a daily driver.
When I will be done, I’ll upload the results of the benchmark and the updated data, but for now I can not set this issue as “solved” because I can’t actually test everything right now.
The “fix” up there “works”, but other than “working” I can’t say anything else for certain…
X11 is and will remain dead. It can obviously still be used, evenmore for the non-modern, non-gaming distros, it may even be a better option, but mainstream Distros are and will be on Wayland now. ↩︎
I have to close this as “fixed” even if “the fix can’t be perfect”…
Long story short:
The “ATI (radeon)” driver doesn’t support Vulkan.
The “amdgpu” driver doesn’t work well with GCN 1, 2 and 3 cards, and therefore is off by default.
In this issue my PC had problems turning ATI off.
I can’t say stuff for GCN 4 and 5 because I have no personal experience with them, and heard nobody really having any issues.
This comment down here
shows that stuff “works” thanks to this
action.
I made a new page on this Forum (about this problem) which is somewhat of a basic guide, which contains the problems I have been having throughout these last years with this iGPU.
If I will need to open a new issue about this CPU+iGPU in particular then I will, but if I wont then this issue and that “guide” will be everything that’s needed to know and/or necessary to solve your problems.
