Iddues with radeon graphics and radeontop

[mm3100]

Hello everyone,

Under Buster I used to have odd freezing of one standalone unity game. It would freeze for 1 or 2 seconds after each action. Looking at radeontop it would show how it works, and once it freezes all stats would go to 0.
After upgrading to Bullseye those freezes stopped, I was happy it got fixed, but then once I did clean installation of Bullseye those freezes started again as in Buster. I am at loss why.

I have Radeon HD 7450M and have installed necessary non-free firmware as before. And I have no clue where to even look as to possible issue, it is even more confusing to me that it worked great after upgrade. But not after clean installation. I have followed wiki on ATI card setup
https://wiki.debian.org/AtiHowTo

Firmware, is loaded, no issues such as warnings/error are shown in journal, no output in console when running unity game. I am have hybrid graphics so I run it using DRI_PRIME offloading, I have checked and it does run on radeon.

Another thing is that radeontop shows odd results, even when not in use I have wrong reading, example right now

Code: Select all

4457M / 1024M VRAM 435.27% │                                                                                  
2183M / 1018M GTT 214.43% │                                                                                  
0.90G / 0.00G Memory Clock    inf% │
0.75G / 0.75G Shader Clock 100.00% │  

Clearly those are wrong and not possible. Could it be some kind of bug or something on my end? I don't know where to even look for start of those issues. If anyone knows anything please say.

Nothing yet?

I have checked and it does run on radeon.

You're sure the new install isn't using amdgpu? I think a 7450 could use either?

Sadly my card is just a generation too old, using TeraScale 2 architecture. So I can't use experimental amdgpu.

If your graphics card is built on GCN 1.0 or GCN 1.1 (also known as being from the "Southern Islands" or "Sea Islands" card families), you may enable experimental AMDGPU support in order to see potentially better performance and Vulkan support.

And yeah, uses radeon drivers
