Hi!

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

merkaba:~> grep . /sys/devices/system/cpu/cpu[0-3]/cpufreq/cpuinfo_cur_freq

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.

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.

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.

Did you test the 3.15-rc kernels?  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.

Thanks,

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).

Or is that just you have tried intel_pstate for the first time?

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.

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
