--- Comment #18 from Thomas Renninger <tr...@suse.de> 2010-11-10 20:12:35 --- Ok, there is CPPC function wich probably means "Change" PPC in CPU0IST table. But this one is only called via _PCT which is only called at cpufreq driver load time. So I have no idea how _PPC gets modified when this magic button is hit, when switching to battery or anywhen after boot up. Can you verify that when the CPU is limited, that you see this limit here: cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit Do you know about any Clevo or related platform specific driver you may have running? I may miss something..., I looked at drivers/platform/x86/* whether a driver directly modifies VPPC or calls CPPC func, but couldn't find anything. I am stuck here. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
