Power, Voltage, Current readings

Power:

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

Voltage:

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

Current:

• anything older than Vega 10 except Hawaii, Bonaire, Fiji, Tonga
• 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.

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))
