Yes , this solved the problem for me.
I had to resolve some conflicts myself when reverting that
commit. Hard work :).
Here is a 10-seconds trace of the used frequencies when
in "desktop-idle":

I would like to try to reproduce the issue also.

Note that with Ubuntu 14.04, I had issues where my CPU
would lock at pstate 24 (not always 24, but usually),
regardless of load.
However, it was always after an S3 suspend, occurred 100%
of the time, and was independent of intel_pstate or
acpi-cpufreq CPU frequency scaling drivers.
Since changing my test server to Ubuntu server edition 16.04
(development version), I have not had those issues. While I have
no proof, I have assumed the issue elimination was somehow related
to the change to systemd.
It might be worth observing both what the intel_pstate is asking for
and what the processor is actually doing.
What is being asked for:
# rdmsr --bitfield 15:8 -d -a 0x199
What is being given:
# rdmsr --bitfield 15:8 -d -a 0x198
An old problematic example from an idle system (mine)
Note, my minimum pstate is 16:

To gain further insight, it might also be worth acquiring
some trace data. On an otherwise idle system, do:
# perf record -a --event=power:pstate_sample sleep 300
If pressed for time, your sleep time can be less than 5 minutes,
but try to get at least 100 seconds.
The resulting perf.data file will be too big to include as an
on-list attachment, but send it (or them) to me off-list for
post processing, and I'll report back.

If Jörg runs with
turbostat -i 1 --msr=0x199
We can tell whether if we requested or the same problem you had.
I tried on Ubuntu LTS 14.04 on same Haswell CPU model, I didn't see
this issue.

There seems to be something odd about the Jörg's setup, or we'd have
received more reports about this issue.
Question is what that is and what really makes the difference.

I think, somehow we entered performance mode from powersave by default
turbostat -i 1 --msr=0x199 will tell us.

Great, thanks!
To me, the only area where things are really different before and after the
revert is the initialization, so that likely is when the problem triggers.
And sure enough, there is an initialization problem in intel_pstate.
Please test the patch below instead of the revert and let me know if it
makes any difference.
It (or equivalent) will need to be applied anyway, so we'll work on top of it
going forward, but also it may just be sufficient to address the problem you're
seeing.

From: Rafael J. Wysocki <[email protected]>
Subject: [PATCH] intel_pstate: Do not set utilization update hook too early
The utilization update hook in the intel_pstate driver is set too
early, as it only should be set after the policy has been fully
initialized by the core. That may cause intel_pstate_update_util()
to use incorrect data and put the CPUs into incorrect P-states as
a result.
To prevent that from happening, make intel_pstate_set_policy() set
the utilization update hook instead of intel_pstate_init_cpu() so
intel_pstate_update_util() only runs when all things have been
initialized as appropriate.

Very Interesting.
I would still like to get a trace sample to post process.
Copied from a previous e-mail:
On an otherwise idle system, do:
# perf record -a --event=power:pstate_sample sleep 300
If pressed for time, your sleep time can be less than 5 minutes,
but try to get at least 100 seconds.
The resulting perf.data file will be too big to include as an
on-list attachment, but send it (or them) to me off-list for
post processing, and I'll report back.

Never mind. I had not seen some of the e-mails, in particular
the one where Rafael had figured out the issue.

Well, more work to do then.
I've just noticed a bug in this patch, which is not relevant for the results,
but below is a new version.

Please apply the patch below and take a (1s or so) trace from the pstate_sample
tracepoint (under /sys/kernel/debug/tracing/events/power/ on my systems).
Then please apply the revert instead of it and take a trace from that tracepoint
again and send both of the traces to me.

From: Rafael J. Wysocki <[email protected]>
Subject: [PATCH] intel_pstate: Do not set utilization update hook too early
The utilization update hook in the intel_pstate driver is set too
early, as it only should be set after the policy has been fully
initialized by the core. That may cause intel_pstate_update_util()
to use incorrect data and put the CPUs into incorrect P-states as
a result.
To prevent that from happening, make intel_pstate_set_policy() set
the utilization update hook instead of intel_pstate_init_cpu() so
intel_pstate_update_util() only runs when all things have been
initialized as appropriate.

OK, patch is applied.
After some configurations and compilations I'm there.
Under pstate_sample I see:
enable filter format id trigger
what to do now ? (never did tracing before)

Send us the trace file.
Also your kernel config doesn't have many modules, Is it a custom
configuration you do for your system?

Here's what I do, for completeness:
# echo 0 > /sys/kernel/debug/tracing/tracing_on
# echo global > /sys/kernel/debug/tracing/trace_clock
# echo nop > /sys/kernel/debug/tracing/current_tracer
# echo 1000 > /sys/kernel/debug/tracing/buffer_size_kb

# echo "" > /sys/kernel/debug/tracing/trace
# echo 1 > /sys/kernel/debug/tracing/tracing_on
Then, (after a while) make a copy of the trace file.

Yes, it proves that pstate was requested, but it does not disprove that
the processor is in the locked up state.

While there are other scenarios that would explain the
data, it is consistent with the processor locked pstate
scenario.
The suggestion is to limit what the intel_pstate driver will ask
for, and observe what is being given.
Example (using my computer, which is working fine):
1.) What is the minimum?
$ cat /sys/devices/system/cpu/intel_pstate/min_perf_pct
42
2.) Set the maximum the same as the minimum?
$ sudo su
root@s15:/home/doug/temp#
root@s15:/home/doug/temp# echo "42" > /sys/devices/system/cpu/intel_pstate/max_perf_pct
3.) check it:
root@s15:/home/doug/temp# cat /sys/devices/system/cpu/intel_pstate/max_perf_pct
42
3.) Observe what is being asked for and given:
root@s15:/home/doug/temp# modprobe msr
root@s15:/home/doug/temp# rdmsr --bitfield 15:8 -d -a 0x198

Jörg: As Srinivas mentioned, your kernel configuration is very
odd. You mentioned you are using Ubuntu 14.04.4. Could you try
the Ubuntu mainline kernel 4.6-rc1? You can get it here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc1-wily/
The reason I have been asking for trace data via a different
method than Rafael and Srinivas, is because I use a set
of post processing tools, originally created by the
original intel_pstate driver maintainer.

I compile a minimum kernel for my notebook. The hardware is fix and
will never change. So I don't need thousends of modules to compile.
Kbuild supports this with target "localmodconfig".
In the rare cases where I get new usb-hardware I add a new driver
and compile a new kernel which takes only a minute.

Thanks!
First of all, the sampling mechanics works as expected in the failing case,
which is the most important thing I wanted to know. However, there are anomalies
in the failing case trace. The core_busy column is clearly suspicious and it
looks like CPUs 2 and 3 never really go idle. I guess we'll need to find out
why they don't go idle to get to the bottom of this, but it firmly falls into
the weird stuff territory already.
In the meantime, below is one more patch to test, on top of the previous one
(that is, https://patchwork.kernel.org/patch/8714401/).
Again, this is a change I'd like to make regardless, so it would be good to
know if anything more has to be done before we go further.

Subject: [PATCH] intel_pstate: Avoid extra invocation of intel_pstate_sample()
The initialization of intel_pstate for a given CPU involves populating
the fields of its struct cpudata that represent the previous sample,
but currently that is done in a problematic way.
Namely, intel_pstate_init_cpu() makes an extra call to
intel_pstate_sample() so it reads the current register values that
will be used to populate the "previous sample" record during the
next invocation of intel_pstate_sample(). However, after commit
a4675fbc4a7a (cpufreq: intel_pstate: Replace timers with utilization
update callbacks) that doesn't work for last_sample_time, because
the time value is passed to intel_pstate_sample() as an argument now.
Passing 0 to it from intel_pstate_init_cpu() is problematic, because
that causes cpu->last_sample_time == 0 to be visible in
get_target_pstate_use_performance() (and hence the extra
cpu->last_sample_time > 0 check in there) and effectively allows
the first invocation of intel_pstate_sample() from
intel_pstate_update_util() to happen immediately after the
initialization which may lead to a significant "turn on"
effect in the governor algorithm.
To mitigate that issue, rework the initialization to avoid the
extra intel_pstate_sample() call from intel_pstate_init_cpu().
Instead, make intel_pstate_sample() return false if it has been
called with cpu->sample.time equal to zero, which will make
intel_pstate_update_util() skip the sample in that case, and
reset cpu->sample.time from intel_pstate_set_update_util_hook()
to make the algorithm start properly every time the hook is set.

For me it looks like the previous one of the failing case.

May be something odd in this config is triggering this issue, we are
not going to idle on some CPUs.

Yes, but that might be part of the problem, as for some CPUs
there is never a long duration, and thus the long duration
check never kicks in driving the target pstate down.

This has been observed several times before [1].
Due to beat frequencies between desktop type frame rates
and such, the worst manifestation of the issue seems to be
for 300 Hz kernels, but Ubuntu uses uses 250 Hz.
Oh look, Jörg is using 300 Hz!!
$ grep CONFIG_HZ .config_jorg
# CONFIG_HZ_PERIODIC is not set
# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
CONFIG_HZ_300=y
# CONFIG_HZ_1000 is not set
CONFIG_HZ=300

I'm compiling a 300 Hz kernel now, also with "# CONFIG_NO_HZ is not set",
but I have never been able to re-create these type of findings before.
I have also tried several other things in an attempt re-create Jörg's
Case, so far without success.

I use 300Hz because of:
"250 Hz is a good compromise choice allowing server performance
while also showing good interactive responsiveness even
on SMP and NUMA systems. If you are going to be using NTSC video
or multimedia, selected 300Hz instead." (from KBuild helptext)
-> I often use multimedia so according this text 300 Hz is the better
choice.

Again from KBuild helptext:
"CONFIG_NO_HZ:
This is the old config entry that enables dynticks idle.
We keep it around for a little while to enforce backward
compatibility with older config files."
-> NO_HZ outdated.

The traces show that idle task is constantly running without sleep. The
driver is processing samples for idle task for every 10ms and
aperf/mperf are showing that we are always in turbo mode for idle task.
Need to find out why idle task is not sleeping.

No, they (at least the first one, I didn't look at the next one yet)
show that CPUs 2 and 3 are spending around 99% of their time not in state
C0. That the sample rate is ending up at ~10 Milliseconds, indicates some
high frequency (>= 100Hz) events on those CPUs. Those events, apparently,
take very little CPU time to complete, hence a load of about 1% on average.
By the way, I can recreate the high sample rate with virtually no load
on my system easy, but so far have been unable to get the high CPU
frequencies observed by Jörg. I can get my system to about a target pstate of
20 where it should have remained at 16, but that is about it.

That column pretty much always says "idle" (or swapper for my way of doing
things). I have not found it to very useful as an indicator, and considerably
more so since the utilization changes.

I contend that is it.
I don't have enough reverted data, but so far this seems very much like
that bug report I referenced earlier.

I mean atleast on once CPU. I am not saying they are looping, but the
wakeup time is less than 10ms, so the driver will not scale the load
for idle time.

How do you figure that out if I may ask? It is not so obvious to me
to be honest.

You can use ./scripts/diffconfig (in the kernel source tree) to find
differences between your working config and the Jörg's one and try to
flip the bits that may matter in your config.

Well, that will require further investigation, so I have created a
kernel Bugzilla entry for the tracking of this issue:
https://bugzilla.kernel.org/show_bug.cgi?id=115771
I would like to communicate through it going forward if that's not a problem.

The trace was not in the form for the post processing tools, so I had
to manually import the trace into a spreadsheet and manually add new columns
calculated from the others.

Why?
Unless I misunderstood, because the trace data indicates that the those CPUs
are going into some deeper C stsate than C0 for most of their time.

OK
It could be C1 with relatively short periods spent in it.

But how long do they stay in those states every time?
Average residencies need to be well below 10 ms for the trace to be
produced every 10 ms, so the question seems to be what kicks the CPUs
out of idle states so often. On a completely idle system, that's
highly suspicious.
