Your BIOS does not export _PSS mothods and that's why it's failing. If you can find SSDT dump with _PSS methods for the *exact* CPU model from "somewhere", you can insert it into your DSDT and override. There are many possible causes. Some BIOS do not care about workstation/server class CPUs. Some BIOS only exports _PSS methods when it "thinks" the OS supports it. Some (broken) BIOS dynamically constructs/loads/unloads _PSS methods during cold boot to limit boot-time frequency (usually for mobile processors), then acpi_perf misses it. Some times calibrated frequency at boot-time is too wild and it does not match any frequency from probed _PSS. Newer models are more complicated because of dynamic FSB switching, Turbo Boost, etc. It goes on and on... Intel did not publish vital information to support any CPUs beyond Pentium M family but you may find some clues from Intel BITS source. http://biosbits.org/ Also, Linux ACPI validation test may help, too. http://www.lesswatts.org/projects/acpi/validation.php Some time ago, I have written an ugly patch to support newer processors without _PSS: http://people.freebsd.org/~jkim/est-20110608.diff It worked for my Xeon processors but it may damage your CPU severely, cause fire, etc, etc... Now you're warned. ;-) Note this patch will never be committed, at least in current form, because it has full of guess work from me. > - Arnaud > > > It feels strange that the latest FreeBSD do not support est(4) on > > a 3 years old CPU... Yeah, tell it to the CPU/BIOS/motherboard vendors. :-( Jung-uk Kim
