+## 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.

+| ---------------- | ------------- |
+| Device tree | unsupported |
+| Internal speaker | unsupported |
+| HDMI Out | unsupported |
+| Ethernet | unsupported |
+| Audio jack | unsupported |
