gem5 support for MI450, MI455x, MI500 and fabric interfaces

Hi. Is anybody aware of any ongoing or planned work on AMD instinct series of GPUs (newer than MI300x, such as MI450 , 455, etc) in gem5?

Hi @af-scalemem , we (@abmerop and myself) have not started working on MI4** configurations yet, but in the long term we hope to try and add this. No ETA on when that might be, and of course if you are willing to contribute such a model that would be wonderful!
