The pm-tools also provide scriptĭirectories to hook-in other software when switching power (saving) The package pm-utils provides the pm-action, pm-hibernate, pm-suspendĪnd pm-suspend-hybrid commands. To display more details such as temperature and power, use the -debug option. etc/acpi that deal with handling special acpi buttons on laptops. Lastly, it can indicate a potential for tuning the virtual memory manager. The package acpi-support provides a set of such scripts under The time it takes to switch the CPUs belonging to this policy from one P-state to another, in. cpuinfominfreq Minimum possible operating frequency the CPUs belonging to this policy can run at (in kHz). Xen DomUs can see 8 cores but still see 0000. cpuinfomaxfreq Maximum possible operating frequency the CPUs belonging to this policy can run at (in kHz). Run the scripts they find in their config directory tree under power management: Clearly there are 2 problems here: 1) It is only showing 2 cores on an octal core machine, 2) The CPU model number is 'CPU 0000' and not 'Xeon 5506 2.13GHz'. They provide means to execute commands on these external events. Then there are event manager daemons apmd and acpid Now make that file executable: chmod 0755 /etc/pm/sleep.d/000cancel-hibernate-suspend The content of this file should be: #!/bin/sh sudoedit /etc/pm/sleep.d/000cancel-hibernate-suspend Here is the dmidecode output: dmidecode -t 4 dmidecode 2.9 SMBIOS 2.7 present. We have to create an executable script in /etc/pm/sleep.d/ that will cancel any hibernate or suspend actions. It has 4 cores and each core has 2 threads.

Is is possible to implement driver support for AMD CPUs I'm not a good C programmer to do it myself, but maybe I can help with investigation. One important part of a laptop is the ability to use it on the road. They are not user documentation and should not be treated as such.ĭocumentation is available here.You can disable those power management features at various level. Looks like that power-profiles-daemon only supports Intel CPU power management. Most of them are outdated, but provide historical design context. Feature pages are design documents that developers have created while collaborating on oVirt.
