They tell you what P state was requested not the frequency the core is running at. /sys/devices/system/cpu/cpu1/cpufreq/cpuinfo_cur_freq:2501000 is code for select the highest turbo P state in ACPI frequency table terms. With the HW coordination on the chip all the cores will actually be running at the frequency of the highest requested P state. intel_pstate returns the measured/actual frequency the core ran at during the most recent sample that the driver took. Something is convincing intel_pstate and ondemand that one(or more) cores is very busy. > merkaba:~> sensors > acpitz-virtual-0 > Adapter: Virtual device > temp1: +83.0°C (crit = +98.0°C) > > coretemp-isa-0000 > Adapter: ISA adapter > Physical id 0: +84.0°C (high = +86.0°C, crit = +100.0°C) > Core 0: +83.0°C (high = +86.0°C, crit = +100.0°C) > Core 1: +84.0°C (high = +86.0°C, crit = +100.0°C) > > thinkpad-isa-0000 > Adapter: ISA adapter > fan1: 3586 RPM > > > > Its still hot in this room, but this definately looks saner. > > Thanks, > Martin > >>> >>> >>> >>> Am Montag, 9.

Thing is: With intel_pstate after running PlaneShift *all* cores are in turbo mode. With ondemand acpi only some. At least due to what it requests. I expect one or maybe two cores busy while playing PS. One for PS, and one for other stuff. I will try to make the tests you requested. Quite busy here now. So will take some time.

If so, do they have this problem too? I think I saw this with 3.15-rc7 as well. Not so sure about 3.15-rc5. I now switched to acpi + ondemand governor which seems to work better, as I posted. I still hit cpu throttling, but well its hot inside here. And maybe the fan also needs some cleaning. Anyway, need to get some sleep now. I can test with rc7, rc5 and probably some older rc as I still have those available. Will take some time tough.

Well, my point really is whether or not there is a kernel where you didn't have this problem with intel_pstate (ie. there is a regression in intel_pstate).
