## M1 (T8103)

Devices based on the Apple M1 SoC, released in 2020.

### T8103 Common features

These features are common to all Apple Silicon devices with the M1 (T8103) SoC.

Note that: you can hard adjust the brightness in asahi by setting it in macos first.

## M1 Ultra (T6002)

The M1 Ultra consists of two M1 Max SoCs connected together
in an interleaved UMA configuration. Responsibility for whole-chip functions
is split between the two dice. Since none of the hardware is actually
new, hardware support is identical to the M1 Max. Only a device tree
is required to support this SoC. Machine-specific hardware will still
need to be evaluated on a per-machine basis.

| Feature | Support Level |
| ---------------- | ------------- |
| Device tree | unsupported |
| Internal speaker | unsupported |
| HDMI Out | unsupported |
| Ethernet | unsupported |
| Audio jack | unsupported |
