This one has been a real problem for me. I will provide a brief summary, and more specifics if requested. I have a couple of older laptops (AMD based Dell 1721) that I would like to use for reading documents etc. It took hours to install openSuse on them because the CPU speed is kept at the lowest level. If I do a cpupower frequency-info, it provides a range of valid values from 0.8GHz to 2.2GHz. When I examine entries in /sys/devices/system/cpu/cpufreq I find: cpuinfo_max_freq 2200000 cpuinfo_min_freq 800000 cpuinfo_cur_freq 800000 scaling_max_freq 800000 scaling_min_freq 800000 bios_limit 800000 I am worried about the "bios_limit" being set so low, and where does that setting come from. I did a grep on /etc, /usr/lib, /usr/lib64 and /usr/share and could find no file referencing bios_limit. When I searched /lib I found three modules, including the powernow-k8 module that included that reference. This bios_limit entry is also not present on my other, faster, machine, which does limit overclocking. And I see no place in the 1721 BIOS setup that allows setting a limit on CPU speed. The list of available governors is userspace, ondemand and performance (currently set to userspace, probably because I tried manually the cpupower frequency-set -f 1800000 command, which had no effect. I am back on my faster machine now, and plan to unroll the kernel source and see what I can discover there. I do not know if powernow-k8 sets, or just reads that entry. Any help would be appreciated. I just do not understand why the cpuinfo_max_freq entry can be set to 2.2GHz, while a limit is also set to 0.8GHz.
