[Profiling] Radeon iGPUs reported as not supported

[maxime-modulopi]

I have a Ryzen 7 9800X3D with "Radeon Graphics".

When trying to use the Profiling feature, the Radeon Developper Panel shows "The current hardware is not supported".
However, in the Radeon GPU Profiler documentation, "AMD Ryzen™ Processors with Radeon Graphics" is marked as supported.

@maxime-modulopi Were you able to figure this out? I've been having the same issue.

Sadly no

@marsfan @maxime-modulopi Radeon Developer Panel does not support RGP capture on devices with less than 3 CUs. It is likely that you are hitting this limitation.

@MattGuerrette That would explain it not working on my 9700x, but I also see the same issue on a laptop with a 5700u that has 8 CUs in it.

What's the reason for the 3 CU minimum?

That's unfortunate.
By the way, unless I missed it, this limitation is not written anywhere in the requirements for RGP, so you might want to add it there.

@marsfan Radeon Developer Panel only supports devices using AMD RDNA™ architecture. 5700u uses GCN

The CU count limitation is mainly due to firmware issues on these smaller devices that could impact the data collection and accuracy. For hardware that falls into this CU count category that does not have the same firmware issues, support may be considered on a case-by-case basis.

@MattGuerrette That's a pity. Do you know of an option for profiling GCN systems?
