Hia everyone! I am currently working on S0i3 support for FreeBSD, and I have prepared a sleep testing image to make it easier to test this on a wide variety of different hardware. You can find these images here: https://people.freebsd.org/~obiwac/s0ix/ They are expected to successfully enter S0i3 on 7040 series AMD processors, and may work on a wider variety of (AMD) machines (I do not expect this to work out of the box on Intel, but I have never tried this out). Instructions about how to read the S0i3 entry metrics are available in the /root/README file or on that page. You can also of course build the kernel yourself instead: https://github.com/obiwac/freebsd-s0ix/tree/everything If you are interested in trying this out for yourself, it would be great if you could send me the ACPI dump of your machine (acpidump -dt) as well as the SMU metrics sysctl tree on AMD (sysctl dev.amdsmu.0). Thanks! Aymeric
