Is pre RDNA GPU works with Kernel 6.7?

English Hardware
1

I just updated from old 6.2 kernel to current latest 6.7.4-1-default

I have Vega8 integrated GPU to Ryzen.
Before and in kernel 6.2 it was working - I had GPU acceleration and Wayland was working on this integrated GPU.

Now - I can not even load to Wayland, x11 start in “software acceleration”-CPU rendering - even watching video on youtube use 100% CPU, no hardware acceleration.

lspci -k | grep -A 3 -E “(VGA|3D)”

07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Picasso/Raven 2 [Radeon Vega Series / Radeon Vega Mobile Series] (rev c9)
	Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Picasso/Raven 2 [Radeon Vega Series / Radeon Vega Mobile Series]
	Kernel driver in use: amdgpu
	Kernel modules: amdgpu

it show - it use amdgpu driver, but where hardware acceleration?

Update:
Reason is - Nvidia driver.
I installed to clean disk, anyway it was 4+years old system - boot with no nvidia drivers - AMD gpu works.
But after installing Nvidia drivers - something wrong.

I did check blacklist - there only nouveau, so idk, maybe il deal with it latter.

You do not appear to have an NVIDIA GPU. Why Install the driver???

Why would you expect drivers for an NVIDIA card to work for your AMD Graphics?

To use 100% of GPU memory in CUDA-compute-ML you do need to not have desktop running on that GPU.
And obvious option - use integrated GPU as main, and in my case integrated is AMD GPU.

AMD driver in kernel were working fine with Nvidia GPU driver installed in kernel 6.2
Now - kernel 6.7 there some config being not correct or something - after installing Nvidia driver AMD wont work “out of box” like in next reboot after installing nvidia.
Yes now I have to use Nvidia GPU as main.
I will look how to fix it some time latter.

You are very unclear, and the information given so far in your posts implies there is only the AMD Graphics built into your APU.

Is there a discrete NVIDIA Graphics card installed in your machine, in addition to the Integrated AMD Graphics on your APU?

Update after deleting/moving xorg conf created by Nvidia driver:
mv /etc/X11/xorg.conf /etc/X11/xorg_MV.conf

AMD integrated again works… but works only in X11 session, Wayland just return to login screen.
In kernel 6.2 I had Wayland working on this integrated GPU.
