The user-guide.txt says: bios_limit : If the BIOS tells the OS to limit a CPU to lower frequencies, the user can read out the maximum available frequency from this file. This typically can happen through (often not intended) BIOS settings, restrictions triggered through a service processor or other BIOS/HW based implementations. This does not cover thermal ACPI limitations which can be detected through the generic thermal driver. But there appears to be no way to ignore the limit. I have tried ondemand. Nothing moves. I will reboot and examine the BIOS in detail. At first glance my look into the kernel sources appears to verify that the cpufreq.c driver does pay attention to the bios_limit. At line 707 of cpufreq.c: ** * show_bios_limit - show the current cpufreq HW/BIOS limitation */ static ssize_t show_bios_limit(struct cpufreq_policy *policy, char *buf) { unsigned int limit; int ret; if (cpufreq_driver->bios_limit) { ret = cpufreq_driver->bios_limit(policy->cpu, &limit); if (!ret) return sprintf(buf, "%u\n", limit); } return sprintf(buf, "%u\n", policy->cpuinfo.max_freq); } It is an AMD processor that uses the powernow-k8 module. There is a cpufreq_driver struct that contains .bios_limit, but it never puts touches this entry, as far as I can tell. This is going to take a long study. Been a long while since I have been in the kernel. It might be easier to just buy new computer:-) Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
