Just to add that not just the UVD v6 of GCN4-based cards is supported, but since Enhancer v2.2 and RadeonHD v5 in August/September 2022 also the UVD v3/v4 of GCN1-based cards (but not with 4k support, of course, because that only starts with UVD v5).

MorphOS also supports:
- HD7xxx up to HD7670
- HD8xxx up to HD8490
- R5 up to R5 235X (probably also R5 310)
...which are all TeraScale 2 (...and doesn't support HD69xx, which is TeraScale 3).
> which is some generations before GCN4.
Yes, but TeraScale 2 to GCN1 is just two generations :-)
Edit: added R5 310
