[Feature]: support gfx902 and gfx90c #145

Open rainhenry opened 3 months ago

Suggestion Description

Will it be possible to support gfx902 and gfx90c in the future? Do you have a table showing the correspondence between these device code and specific retail chip models? For example, gfx902 is Ryzen 3 2200G. gfx90c is Ryzen 7 5800U.

Will it be possible to support gfx902 and gfx90c in the future?

Perhaps, I've seen some commotion on the LLVM repository about adding support for a 'generic' HIP target that is not GPU-specific. I don't know a lot about it, though. For now our focus is still on the GPUs that are officially enabled for ROCm by AMD (see here). If you have any specific issue with those GPUs you mentioned, I don't mind investigating a fix. I've personally had mixed results with gfx90c and I've heard about issues with APUs in general. It seems that a decent portion of rocPRIM tests does actually work on my own gfx90c, but i haven't tested the examples yet. Of course, some pre-compiled libraries like rocBLAS etc will not work as they will not have those APU targets enabled by default. In theory the HIP-Basic, rocPRIM and hipCUB examples should work fine.

Do you have a table showing the correspondence between these device code and specific retail chip models? For example, gfx902 is Ryzen 3 2200G. gfx90c is Ryzen 7 5800U.

The only such list I know of for non-ROCm supported GPUs is in the LLVM documentation: https://llvm.org/docs/AMDGPUUsage.html#processors
