It is more useful to show sysctl dev.cpu. I suspect your bios reports C-states in a way which we do not parse properly. I am not aware of AMD-specific analog for the Intel' document 'Processor Vendor-Specific ACPI Interface Specification'. If somebody has a pointer to AMD version and wants to test, I am willing to code that. _______________________________________________ freebsd-acpi@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscr...@freebsd.org"
