Finally, I can use cycles renderer of blender3 on the gfx803.
But I cannot find the reason of problem, I just changed all of __noinline__ to __inline__, and compile cycles for gfx803.
At the same time, ROCm-5.2.3 always report a mem fault error, then ROCm-5.3 released, everything is ok.
I am afraid the next version of ROCm may cause cycles break again, but right now, it can run successfully.

Install ROCm First https://docs.amd.com/bundle/ROCm-Installation-Guide-v5.3/page/Introduction_to_ROCm_Installation_Guide_for_Linux.html

- Install ROCm-5.3.0
sudo dpkg -i hsa-rocr_1.7.0.50300-63.20.04_amd64.deb7z x blender331-gfx803.7z
The kernel_gfx803.fatbin is on the blender331-gfx803/3.3/scripts/addons/cycles/lib/.
My modification is very simple.
- modify
intern/cycles/kernel/device/hip/compat.h, change all of__noinline__to__inline__ - modify
intern/cycles/device/hip/util.h, change9to8, then cycles can use gfx803.
I test cube_diorama successfully.
But I cannot guaruntee we won't meet other problems. You could have a try with your own risk.
My suggestion is just buy a ROCm offically supported card, like Vega64, RadeonVII, RDNA.
| OS | linux | Python | ROCm | GPU | Blender |
|---|---|---|---|---|---|
| Ubuntu-20.04.6 | 5.15 | 3.8.10 | 5.4.1 | RX580 | 3.4.1 |
I tried blender-3.4.1 with ROCm-5.4.1, at least cube demo can render properly. The modification is just same.
