Power readings

[VisualEhrmanntraut]

• [x] anything older than Vega 10 except Hawaii, Bonaire, Fiji, Tonga
• [x] Vega 10
• [ ] Vega 12 (Requires metrics table)
• [ ] Vega 2x (Requires metrics table)
• [ ] Renoir (Requires metrics table)
• [ ] RDNA (Requires metrics table)

SMU/SMC metric table transfer requires allocating GPU memory. No idea how it could be done in this kext.

Raven-based iGPUs don't support power readings as far as I can tell.

[VisualEhrmanntraut]

current/voltage readings not possible (GPU doesn't expose such readings afaict)

[VisualEhrmanntraut]

voltage readings seem to exist actually, but not current. current can be inferred using power and voltage (Power (W) / Voltage (V) = Current (I))
