Coming from the almost ps5 land. The bc250 it used to be a dirt cheap crypto mining bord that uses discarded ps5 apus cut to 6 cores and 24cu. Well the cores can oc to 4ghz for most and recently someone found a way to enable more cu some line mine get all 40 =) anyway with kernel parameters you can increase gtt memory so you can access more than 5.5 gb. As i understand it the limit is there to not cause problems with suspend and resume
Add to kernel parameters amdgpu.gttsize=14750 ttm.pages_limit=3959290 ttm.page_pool_size=3959290

Re: PlayStation 5 Linux Tested: Steam PC vs Native PS5 Games
Can add that enabling cu have been verified working in Linux for the ps5 but really is not a big bump to go from 36 cu to 40
