Hardware frequency scaling is turned off in BIOS, or it is turned off as much as possible, although I guess that some resigual scaling, to avoid a burndown cannot be turned off through the stock BIOS interface.
I want to compile ATLAS from SBo. No matter how I try (cpufreq-set, powersave governor, etc), ATLAS detects cpu scaling and doesn't compile.
I have an intel cpu:
Code:
root@delllaptop:/opt/anaconda3# cat /proc/cpuinfo
model name : Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz
Any suggestions on how to compile ATLAS?
Would rebooting with 'init=/bin/sh' help?

The scaling driver for your CPU must be intel_pstate. It can be disabled by passing intel_pstate=disable to the kernel.
