The publicly available data just says that the SoC reports "a temperature on its own scale" relative to a Tctl_max which "is specified in the power and thermal data sheet" (that I have been unable to locate). Everyone seems to assume that the step size is 0.125K but I haven't found that publicly documented anywhere. The AMD Product Brief states that the maximum temperature is 90=B0C but using that as Tctl_max gives me temperature readings that don't look right. >And on a fanless APU > ># sysctl -a dev.cpu.0.temperature >dev.cpu.0.temperature: 62.6C > ># sysctl -a dev.amdtemp.0.core0.sensor0 >dev.amdtemp.0.core0.sensor0: 63.1C At what ambient temperature? I see a similar value from my (idle) APU3 but don't believe the (implied) ~35K junction-to-ambient difference. --=20 Peter Jeremy --bCsyhTFzCvuiizWE Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE7rKYbDBnHnTmXCJ+FqWXoOSiCzQFAl5E+R1fFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEVF QjI5ODZDMzA2NzFFNzRFNjVDMjI3RTE2QTU5N0EwRTRBMjBCMzQACgkQFqWXoOSi CzQkqA//e/9S82+WCB/5JKfpL4Zpb7dcrLPDZGt4CNhq/+F5w8mAUklO8k+I7mH2 KuUi5W8Xx4BUpVXyYBPfJGj13kVCuosQcaTJndofY7NKaMDQTAnHGybijXKtbrYv cI0b6dFP0Txea7mMIDBJw0jLC/3E15jyCovP5RVDwJs3NBjY3vge7/Z5UikvMkhg UHZHLSi3hUCw0Z/LlM612imi5WnPcnTknPoF9l+dROWca2QPvg+3Yi6suQzj14cj 5UHa0V6FBh4pB/+RMaky7iY5XEwQ8ZVzPrNOX/EZ26UpBI3KptKtEHoFvUytwwPc 9sYYHpKR+tIkfLRlX6ObTI1IRm4T2pOFNB7clwRR5Y9OuHIPP1JNM2b3/OifGpSt eg104df5Xzkoe0XG18iED+fCv6xOU6JS1AiAHYVjLro8+ctHRKoYXpDOTWgdcXFc tu4nFAiQn0sgwbEoVTC01b0KMAvHH1uv8N/q8SbhX41WGW1YZjcgzrJdeg/cRQVy Xp6BylIzyF9Nuk7c9IIplCCQg6hqcxegTCaEtFbI++IIe9dV0/yzL8PxzdhG1xAh ItJQO4jrOxRJ7aC2a7oJ3qzgZEaFArwa0jCdiitap+hGFJONKTY6WvOijoq3QWTh WbQU+oxOUIi/jVmRu1hrjcmovsmNwHqk8jGGhpCUxDIg92+rV8A= =05YL -----END PGP SIGNATURE----- --bCsyhTFzCvuiizWE--
