It can be43 queried on macOS using the following command:44 45 $ ioreg -d2 -l | grep target-type46 47 <socid> is the lowercased SoC ID. Apple uses at least *five* different48 names for their SoCs:49 50 - Marketing name ("M1")51 - Internal name ("H13G")52 - Codename ("Tonga")53 - SoC ID ("T8103")54 - Package/IC part number ("APL1102")55 56 Devicetrees should use the lowercased SoC ID, to avoid confusion if57 multiple SoCs share the same marketing name. This can be obtained from58 the `compatible` property of the arm-io node of the Apple Device Tree,59 which can be queried as follows on macOS:60 61 $ ioreg -n arm-io | grep compatible62 63properties:64 $nodename:65 const: "/"66 compatible:67 oneOf:68 - description: Apple M1 SoC based platforms69 items:70 - enum:71 - apple,j274 # Mac mini (M1, 2020)72 - apple,j293 # MacBook Pro (13-inch, M1, 2020)73 - apple,j313 # MacBook Air (M1, 2020)74 - apple,j456 # iMac (24-inch, 4x USB-C, M1, 2021)75 - apple,j457 # iMac (24-inch, 2x USB-C, M1, 2021)76 - const: apple,t810377 - const: apple,arm-platform78 79 - description: Apple M2 SoC based platforms80 items:81 - enum:82 - apple,j413 # MacBook Air (M2, 2022)83 - apple,j473 # Mac mini (M2, 2023)84 - apple,j493 # MacBook Pro (13-inch, M2, 2022)85 - const: apple,t811286 - const: apple,arm-platform87 88 - description: Apple M1 Pro SoC based platforms89 items:90 - enum:91 - apple,j314s # MacBook Pro (14-inch, M1 Pro, 2021)92 - apple,j316s # MacBook Pro (16-inch, M1 Pro, 2021)93 - const: apple,t600094 - const: apple,arm-platform95 96 - description: Apple M1 Max SoC based platforms97 items:98 - enum:99 - apple,j314c # MacBook Pro (14-inch, M1 Max, 2021)100 - apple,j316c # MacBook Pro (16-inch, M1 Max, 2021)101 - apple,j375c # Mac Studio (M1 Max, 2022)102 - const: apple,t6001103 - const: apple,arm-platform104 105 - description: Apple M1 Ultra SoC based platforms106 items:107 - enum:108 - apple,j375d # Mac Studio (M1 Ultra, 2022)109 - const: apple,t6002110 - const: apple,arm-platform111 112additionalProperties: true113 114...115
