From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Introduce frequency QoS, based on the "raw" low-level PM QoS, to
represent min and max frequency requests and aggregate constraints.

The min and max frequency requests are to be represented by
struct freq_qos_request objects and the aggregate constraints are to
be represented by struct freq_constraints objects.  The latter are
expected to be initialized with the help of freq_constraints_init().

The freq_qos_read_value() helper is defined to retrieve the aggregate
constraints values from a given struct freq_constraints object and
there are the freq_qos_add_request(), freq_qos_update_request() and
freq_qos_remove_request() helpers to manipulate the min and max
frequency requests.  It is assumed that the the helpers will not
run concurrently with each other for the same struct freq_qos_request
object, so if that may be the case, their uses must ensure proper
synchronization between them (e.g. through locking).

In addition, freq_qos_add_notifier() and freq_qos_remove_notifier()
are provided to add and remove notifiers that will trigger on aggregate
constraint changes to and from a given struct freq_constraints object,
respectively.

No, it shouldn't.

For the min frequency, the effective constraint needs to be the
maximum of all requests, because that satisfies all of them (each
request means "the frequency cannot be less than this").

Likewise, for the max frequency, the effective constraint needs to be
the minimum of all requests, as each of them means "the frequency
cannot be more than this").

[Also note that the current code in device PM QoS uses MIN and MAX
here in the same way. :-)]

These min/max_freq_notifiers fields seem unused? They're initialized but 
the freq_qos_add/remove_notifier calls use min/max_freq.notifiers directly.

Should probably just be dropped.

Never mind, I see now that pm_qos_constraints.notifiers is actually a 
pointer to notifier block provided by somebody else.

Hi Rafael,

Not sure, but I think it is this one that
causes complaining when I try to set the
intel_pstate driver to passive mode.
I started from active mode, powersave governor,
no HWP.

Kernel: 5.4-rc7

I did not go back and try previous 5.4 RCs.
I did try kernel 5.3-rc8, because I already had
it installed, and it worked fine.

I use a script (for years), run as sudo:

doug@s15:~/temp$ cat set_cpu_passive
#! /bin/bash
cat /sys/devices/system/cpu/intel_pstate/status
echo passive > /sys/devices/system/cpu/intel_pstate/status
cat /sys/devices/system/cpu/intel_pstate/status

And I get this (very small excerpt):

freq_qos_add_request() called for active request
WARNING: CPU: 1 PID: 2758 at kernel/power/qos.c:763 freq_qos_add_request+0x4c/0xa0

...

I'll attach the whole thing, but it will likely get removed
from the general list e-mails.

Apologies if people are getting this e-mail twice.
Because it had an attachment, I think it got deleted
from list distribution.

I forgot to mention, other than the error messages,
things seems to work fine.

After looking at the git tags for this patch,
I tried kernel 5.4-rc2, which was the closest
Kernel I had to before the patch set was added.
It worked fine, as expected.

Updated summary of previous emails:
This patch or patch set breaks the after boot
ability to change CPU frequency scaling drivers.

Using a workaround of booting with
"intel_pstate=passive" seems to prevent the errors.

Changing between the intel_pstate and intel_cpufreq drivers
(i.e. between active and passive modes)
after boot, either way, causes the errors. i.e.

Failed to add freq constraint for CPU7 (-22)
(2 per CPU per attempt)

This is 100% repeatable.

> I forgot to mention, other than the error messages,
> things seems to work fine.

Correction: It is actually quite bad. Eventually,
there will be a "Segmentation fault (core dumped)",
and then even re-boot gets stuck and the only
recourse seems to be the reset button.

This is not 100% repeatable.

I did this (kernel 5.4-rc8):

Sometimes I get this:

grep . /sys/devices/system/cpu/intel_pstate/*
/sys/devices/system/cpu/intel_pstate/max_perf_pct:100
/sys/devices/system/cpu/intel_pstate/min_perf_pct:42

Instead of this:

grep . /sys/devices/system/cpu/intel_pstate/*
/sys/devices/system/cpu/intel_pstate/max_perf_pct:100
/sys/devices/system/cpu/intel_pstate/min_perf_pct:42
/sys/devices/system/cpu/intel_pstate/no_turbo:0
/sys/devices/system/cpu/intel_pstate/num_pstates:23
/sys/devices/system/cpu/intel_pstate/status:active
/sys/devices/system/cpu/intel_pstate/turbo_pct:18

But do not yet know the exact way to reliably
create it.

This is as far as I got so far.

These messages come from acpi_processor_ppc_init() and
acpi_thermal_cpufreq_init(), AFAICS, which are invoked by
acpi_processor_notifier() and that is invoked by the
blocking_notifier_call_chain() in cpufreq_online() which tirggers for
new policies after adding the max freq QoS request to
policy->constraints.

The requests added by them should be removed by
acpi_processor_ppc_exit() and acpi_thermal_cpufreq_exit(),
respectively, invoked by the blocking_notifier_call_chain() in
cpufreq_policy_free(), but it looks like that doesn't happen.

However, I now also see that freq_qos_remove_request() doesn't clear
the qos field in req which is should do, so freq_qos_add_request()
will complain and fail if the object pointed to by req is passed to it
again.

I'll send a patch to test for this later today.

Yes the patch fixes the problem. Thanks.

I tested several hundred times switching between
passive and active modes with the intel_pstate driver,
including with various CPUs disabled and re-enabled.
