during playing PlaneShift with Intel gfx.
I get the impression that Intel P-State driver turbo modes all of the cores
needlessly *and* permanently once this condition is triggered. Usually
temperature is just about 55-60 degree celsius. But not at maximum.
I see this:

Will reboot now to see whether it resets that condition. Didn´t happen during the whole
day.
But seems to happen after a while of playing PlaneShift.
Any hints?
Thanks,

Hi!
Added linux-pm to Cc. Also reboots seems to fix up the condition:

Still hot in here and after reboot and login into KDE session there is quite
some CPU activity for a while.
But way better than before.
I can test whether this also happens with ACPI cpufreq driver.
I think I didn´t see this with 3.14.

Way better with ACPI cpufreq driver and ondemand governor:
merkaba:~> grep . /sys/devices/system/cpu/cpu[0-3]/cpufreq/cpuinfo_cur_freq

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.
Thanks,

Hi Martin,
Can you send the output of:
turbostat sleep 10
and
for i in 0 1 2 3; do rdmsr -p $i -u -f15:8 0x198; done
For the normal and bad case please.

This is ondemand/acpi_cpufreq telling a well documented lie. 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.

That bug report is old, and made some sense at the time
it was entered.
Recent entries are all calling for it to be enabled by default again.
For my part of it, I was merely suggesting caution.

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.

It throttled just once so far.
Still 3.15 kernel. Only change: I upgraded from 8 GiB to 16 GiB of RAM.
This may lower CPU usage due to handling page scanning or swapping a bit,
as PlaneShift tends to take about 4 to 5 GiB RSS easily.
Should I hit throttling temperatures I will try to capture this output
once more.
Thanks,
Martin

Okay, here we have the bad, bad case – see other mail for good and
a bit bad case (was not yet fully throttling):

I had these with several hundred events... maybe be a bit lower due to
lowering Akonadi load by increasing innodb_buffer_poolsize from 80 to 512 MiB.
But just guess work.
I did have CPU throttling with ACPI and ondemand too. I don´t think as much
as with PState, but still.
Thanks,
Martin
