Hello hackers@ On a 13/stable system built today with generic kernel, there are these lines for each cpu in the dmesg:- ### est0: <Enhanced SpeedStep Frequency Control> numa-domain 0 on cpu0 est: CPU supports Enhanced Speedstep, but is not recognized. est: cpu_vendor GenuineIntel, msr 231100002100 device_attach: est0 attach returned 6 ### and then, later ### interface hwpstate_intel.1 already present in the KLD 'kernel'! linker_load_file: /boot/kernel/cpufreq.ko - unsupported file type ### The system is a HP ProLiant dual Xeon E5-2690 v2, so there are 40 "cpus" ie 20 if hyperthreading is turned off, in total. I was kind of surprised this didn't work out-of-the-box considering the age of the cpu, its use-context and how widely it was/is used in that context. Clearly I'm doing something wrong or missing something. Should it work? Do I need to build a custom kernel? How can I debug this? I tried using powerd but I understand from later reading that powerd is incompatible with hwpstate_intel, so it's deactivated at the moment. --
