Hi Pau,
It’s probably not possible without a lot of set up, but I have found that GPUs that are “not supported” sometimes still work anyway with certain compute stacks. You would probably need to:
- Find a BIOS for a GCN3 GPU or rip it from a real GPU – This is so the driver loads so at least this is required
- The GPU must be a dGPU or you would need to write an IOMMU model in gem5 to use an APU
- You may need to use an older software stack – These could be hard to find pre-packaged anymore and might require building from source
- May need to rewrite applications with older software stack API – Dependent on previous step
This will certainly not be easy, even if possible. Out of curiosity, which parts of GCN3 are you interested in that are different from Vega or Vega does not have?

Hi,
Is it possible to use GCN3 model to run FS mode? I've done it with VEGA but I'm interested in GCN3 architecture.
In case it is what would it require?
Thank you.
Regards,
Pau
