AMD GPU baking issue

Hello. recantly I bought mobile device with new Ryzen AI MAX 395+ including 8060s iGPU. Unfortunately I encountered problem with GPU accelerated baking, CPU only baking is working perfectly fine. When I click bake, programs starts to proceed with baking although no progress is being shown. After a while baking finishes, but nothing changes in terms of viewport ouput and when I try to interact with it nothing changes ,viewport become static. I can freely interact with UI though like nothing ever happened. When I check the log file it says that baking has actually has been completed but few lines above there is fatal error saying:
[ ERR] <Qt> "[DBG ERROR][Main]" "[SALpp] [Level:FATAL] [Component:DeviceLost] GPU Device lost: driver crash or TDR"
I tried to increase Tdr value to as high as 180s for both keys, I also was testing it with different VRAM allocation values, up to 48gb (16/32/48gb, 48gb being max as my total system memory is 64gb of ram). That haven’t resolved the problem though.

I’ve done some  simple debugging, adding meshes one by one and found out that when total files size of all meshes exceeds ~1gb then the problem occurs. I tried it with different meshes combinations and it always happens somewhere above this threshold.

My specs:

Ryzen AI MAX 395+

Radeon 8060S

64GB RAM DDR5

4TB SSD Samsung 990 Evo Plus

    I already tried to set VRAM to fixed amount up to 48gb as stated above and it clearly shows this specified amount of VRAM is available to GPU. It’s even mentioned in the log that there are 16GB of VRAM available (which is short of maximum amount, but should be planty for this specific case):
    [INFO] <Qt> "[DBG INFO][RunTimeInfo]" glVendor:  "ATI Technologies Inc."
    [INFO] <Qt> "[DBG INFO][RunTimeInfo]" glRenderer:  "Radeon 8060S Graphics"
    [INFO] <Qt> "[DBG INFO][RunTimeInfo]" glVersion:  "4.5.0 Core Profile Context 26.1.1.251223"
    [INFO] <Qt> "[DBG INFO][RunTimeInfo]" glslVersion:  "4.60"
    [INFO] <Qt> "[DBG INFO][RunTimeInfo]" vram:  "16206 MB"

    However there might be something that I’m missing though. I’ll do some additional testing while waiting for the official fix. Thank you for your fast response, I really appreciate that.

    Hello ​@xenoox 

    I’m afraid this is due to your GPU. Considering this is a iGPU, it’s not officially supported by Painter. However, we should have a fix for the coming release.

    Basically when Painter will detect a iGPU, it will split the RAM. Half for CPU and other half for the GPU. Therefore, the software shouldn’t face issue at baking anymore.

     

    In the meantime, you can try this user’s workaround:
    “I set an arbitrary allocation in the machine's EFI to a fixed amount (32GB) and the problem went away on my machine (default setting was fully dynamic with only 512MB reserved for the GPU).”

     

    Hope it helps.
