Daniel Lezcano 8097db407a thermal: Move default governor config option to the internal header
The default governor set at compilation time is a thermal internal
business, no need to export to the global thermal header.

Move the config options to the internal header.

Matthias Kaehlcke 04fa9c804b thermal: devfreq_cooling: Use PM QoS to set frequency limits
Now that devfreq supports limiting the frequency range of a device
through PM QoS make use of it instead of disabling OPPs that should
not be used.

The switch from disabling OPPs to PM QoS introduces a subtle behavioral
change in case of conflicting requests (min > max): PM QoS gives
precedence to the MIN_FREQUENCY request, while higher OPPs disabled
with dev_pm_opp_disable() would override MIN_FREQUENCY.

Daniel Lezcano 44fc73223e thermal: core: Remove pointless debug traces
The last temperature and the current temperature are show via a
dev_debug. The line before, those temperature are also traced.

It is pointless to duplicate the traces for the temperatures,
remove the dev_dbg traces.

Pull scheduler updates from Ingo Molnar:
 "The main changes in this cycle are:

   - Various NUMA scheduling updates: harmonize the load-balancer and
     NUMA placement logic to not work against each other. The intended
     result is better locality, better utilization and fewer migrations.

   - Introduce Thermal Pressure tracking and optimizations, to improve
     task placement on thermally overloaded systems.

   - Implement frequency invariant scheduler accounting on (some) x86
     CPUs. This is done by observing and sampling the 'recent' CPU
     frequency average at ~tick boundaries. The CPU provides this data
     via the APERF/MPERF MSRs. This hopefully makes our capacity
     estimates more precise and keeps tasks on the same CPU better even
     if it might seem overloaded at a lower momentary frequency. (As
     usual, turbo mode is a complication that we resolve by observing
     the maximum frequency and renormalizing to it.)

   - Add asymmetric CPU capacity wakeup scan to improve capacity
     utilization on asymmetric topologies. (big.LITTLE systems)

   - PSI fixes and optimizations.

   - RT scheduling capacity awareness fixes & improvements.

   - Optimize the CONFIG_RT_GROUP_SCHED constraints code.

   - Misc fixes, cleanups and optimizations - see the changelog for
     details"

Daniel Lezcano 40ea568593 thermal/drivers/cpufreq_cooling: Remove abusing WARN_ON
The WARN_ON macros are used at the entry functions state2power() and
set_cur_state().

state2power() is called with the max_state retrieved from
get_max_state which returns cpufreq_cdev->max_level, then it check if
max_state is > cpufreq_cdev->max_level. The test does not really makes
sense but let's assume we want to make sure to catch an error if the
code evolves. However the WARN_ON is overkill.

set_cur_state() is also called from userspace if we write to the
sysfs. It is easy to see a stack dumped by just writing to sysfs
/sys/class/thermal/cooling_device0/cur_state a value greater than
"max_level". A bit scary. Returing -EINVAL is enough.

Remove these WARN_ON.

When setting the cooling device current state from userspace via sysfs,
the operation fails by returning an -EINVAL.

It appears the recent changes with the per-policy frequency QoS
introduced a regression as reported by:

 https://lkml.org/lkml/2020/3/20/599

The function freq_qos_update_request returns 0 or 1 describing update
effectiveness, and a negative error code on failure. However,
cpufreq_set_cur_state returns 0 on success or an error code otherwise.

Consider the QoS update as successful if the function does not return
an error.

Gustavo A. R. Silva 0a8cdc8b14 thermal: qcom: tsens.h: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Anson Huang e20db70dba thermal: imx_sc: add i.MX system controller thermal support
i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller
inside, the system controller is in charge of controlling power,
clock and thermal sensors etc..

This patch adds i.MX system controller thermal driver support,
Linux kernel has to communicate with system controller via MU
(message unit) IPC to get each thermal sensor's temperature,
it supports multiple sensors which are passed from device tree,
please see the binding doc for details.

Niklas Söderlund 267c4d8d13 thermal: rcar_gen3_thermal: Generate interrupt when temperature changes
The desired behavior of the driver is to generate an interrupt and call
thermal_zone_device_update() as soon as the temperature have changed
more then one degree.

When the set_trips operation was implemented it was believed that the
trip window set by the framework would move around the current
temperature and the hysteresis value described in devicetree. The
behavior of the framework is however to set a window based on the trip
points described in devicetree.

Remove the set_trips operation which was not used correctly and update
the temperatures that triggers interrupts directly from the interrupt
handler.

Thara Gopinath f12e4f66ab thermal/cpu-cooling: Update thermal pressure in case of a maximum frequency capping
Thermal governors can request for a CPU's maximum supported frequency to
be capped in case of an overheat event. This in turn means that the
maximum capacity available for tasks to run on the particular CPU is
reduced. Delta between the original maximum capacity and capped maximum
capacity is known as thermal pressure. Enable cpufreq cooling device to
update the thermal pressure in event of a capped maximum frequency.

Pascal Paillet 2f23e319b1 thermal: stm32: Fix low threshold interrupt flood
With the STM32 thermal peripheral, it is not possible to dump the
temperature that has caused the interrupt.
When the temperature reaches the low threshold, we generally read
a temperature that is a little bit higher than the low threshold.
This maybe due to sampling precision, and also because the CPU becomes
hotter when it quits WFI mode.
In that case, the framework does not change the trip points. This leads
to a lot of low threshold interrupts.

The fix is to set the low threshold value 0.5 degrees Celsius
below the actual request.

The problem is not so frequent with the high threshold and it would
no be a good idea to set the threshold value higher than the request.

Peter Mamonov 370f995d58 thermal: of: Make thermal_zone_of_sensor_register return -ENODEV if a sensor OF node is missing
When devm_thermal_zone_of_sensor_register() is called from
hwmon_thermal_add_sensor() it is possible that the relevant sensor is
missing an OF node. In this case thermal_zone_of_sensor_register() returns
-EINVAL which causes hwmon_thermal_add_sensor() to fail as well. This patch
changes relevant return code of thermal_zone_of_sensor_register() to
-ENODEV, which is tolerated by hwmon_thermal_add_sensor().

Here is a particular case of such behaviour: the Marvell ethernet PHYs
driver registers hwmon device for the built-in temperature sensor (see
drivers/net/phy/marvell.c). Since the sensor doesn't have associated OF
node devm_hwmon_device_register() returns error which ultimately causes
failure of the PHY driver's probe function.

The hardware manual states that the operation of the sensor is not
guaranteed outside the range of -45°C to 125°C, not that the readings
are invalid. Remove the bound check and try to deliver temperature

Florian Fainelli e1ff6fc22f thermal: brcmstb_thermal: Do not use DT coefficients
At the time the brcmstb_thermal driver and its binding were merged, the
DT binding did not make the coefficients properties a mandatory one,
therefore all users of the brcmstb_thermal driver out there have a non
functional implementation with zero coefficients. Even if these
properties were provided, the formula used for computation is incorrect.

The coefficients are entirely process specific (right now, only 28nm is
supported) and not board or SoC specific, it is therefore appropriate to
hard code them in the driver given the compatibility string we are
probed with which has to be updated whenever a new process is
introduced.

We remove the existing coefficients definition since subsequent patches
are going to add support for a new process and will introduce new
coefficients as well.

Daniel Lezcano a4c428e523 thermal/drivers/cpu_cooling: Introduce the cpu idle cooling driver
The cpu idle cooling device offers a new method to cool down a CPU by
injecting idle cycles at runtime.

It has some similarities with the intel power clamp driver but it is
actually designed to be more generic and relying on the idle injection
powercap framework.

The idle injection duration is fixed while the running duration is
variable. That allows to have control on the device reactivity for the
user experience.

An idle state powering down the CPU or the cluster will allow to drop
the static leakage, thus restoring the heat capacity of the SoC. It
can be set with a trip point between the hot and the critical points,
giving the opportunity to prevent a hard reset of the system when the
cpufreq cooling fails to cool down the CPU.

With more sophisticated boards having a per core sensor, the idle
cooling device allows to cool down a single core without throttling
the compute capacity of several cpus belonging to the same clock line,
so it could be used in collaboration with the cpufreq cooling device.

Andrey Smirnov 4316237bd6 thermal: qoriq: Convert driver to use regmap API
Convert driver to use regmap API, drop custom LE/BE IO helpers and
simplify bit manipulation using regmap_update_bits(). This also allows
us to convert some register initialization to use loops and adds
convenient debug access to TMU registers via debugfs.

Andrey Smirnov 8e1cda35c3 thermal: qoriq: Pass data to qoriq_tmu_calibration() directly
We can simplify error cleanup code if instead of passing a "struct
platform_device *" to qoriq_tmu_calibration() and deriving a bunch of
pointers from it, we pass those pointers directly. This way we won't
be force to call platform_set_drvdata() as early in qoriq_tmu_probe()
and need to have "platform_set_drvdata(pdev, NULL);" in error path.

must not return an error if interrupts are not defined. Don't return an
error in case of -ENXIO.

YueHaibing 5026061424 thermal: power_allocator: Fix Kconfig warning
When do randbuiding, we got this:

WARNING: unmet direct dependencies detected for THERMAL_GOV_POWER_ALLOCATOR
  Depends on [n]: THERMAL [=y] && ENERGY_MODEL [=n]
  Selected by [y]:
  - THERMAL_DEFAULT_GOV_POWER_ALLOCATOR [=y] && <choice>

The Kconfig option THERMAL_DEFAULT_GOV_POWER_ALLOCATOR selects the
THERMAL_GOV_POWER_ALLOCATOR but this one depends on the ENERGY_MODEL
which is not enabled.

Make THERMAL_DEFAULT_GOV_POWER_ALLOCATOR depend on THERMAL_GOV_POWER_ALLOCATOR
to fix this warning.

Quentin Perret a4e893e802 thermal: cpu_cooling: Migrate to using the EM framework
The newly introduced Energy Model framework manages power cost tables in
a generic way. Moreover, it supports several types of models since the
tables can come from DT or firmware (through SCMI) for example. On the
other hand, the cpu_cooling subsystem manages its own power cost tables
using only DT data.

In order to avoid the duplication of data in the kernel, and in order to
enable IPA with EMs coming from more than just DT, remove the private
tables from cpu_cooling.c and migrate it to using the centralized EM
framework. Doing so should have no visible functional impact for
existing users of IPA since:

 - recent extenstions to the the PM_OPP infrastructure enable the
   registration of EMs in PM_EM using the DT property used by IPA;

 - the existing upstream cpufreq drivers marked with the
   'CPUFREQ_IS_COOLING_DEV' flag all use the aforementioned PM_OPP
   infrastructure, which means they all support PM_EM. The only two
   exceptions are qoriq-cpufreq which doesn't in fact use an EM and
   scmi-cpufreq which doesn't use DT for power costs.

For existing users of cpu_cooling, PM_EM tables will contain the exact
same power values that IPA used to compute on its own until now. The
only new dependency for them is to compile in CONFIG_ENERGY_MODEL.

The case where the thermal subsystem is used without an Energy Model
(cpufreq_cooling_ops) is handled by looking directly at CPUFreq's
frequency table which is already a dependency for cpu_cooling.c anyway.
Since the thermal framework expects the cooling states in a particular
order, bail out whenever the CPUFreq table is unsorted, since that is
fairly uncommon in general, and there are currently no users of
cpu_cooling for this use-case.

Quentin Perret 5a4e5b7895 thermal: cpu_cooling: Make the power-related code depend on IPA
The core CPU cooling infrastructure has power-related functions
that have only one client: IPA. Since there can be no user of those
functions if IPA is not compiled in, make sure to guard them with
checks on CONFIG_THERMAL_GOV_POWER_ALLOCATOR to not waste space
unnecessarily.

Colin Ian King f0a353b4d1 drivers: thermal: tsens: fix potential integer overflow on multiply
Currently a multiply operation is being performed on two int values
and the result is being assigned to a u64, presumably because the
end result is expected to be probably larger than an int. However,
because the multiply is an int multiply one can get overflow. Avoid
the overflow by casting degc to a u64 to force a u64 multiply.

Also use div_u64 for the divide as suggested by Daniel Lezcano.

Guillaume La Roque 421eda108e thermal: amlogic: Add thermal driver to support G12 SoCs
Amlogic G12A and G12B SoCs integrate two thermal sensors
with the same design. One is located close to the DDR controller
and the other one is located close to the PLLs (between the CPU and GPU).

The calibration data for each of the thermal sensors instance is stored
in a different location within the AO region.

Implement reading the temperature from each thermal sensor.

The IP block has more functionality, which may be added to this driver
in the future:
- chip reset when the temperature exceeds a configurable threshold
- up to four interrupts when the temperature has risen above a
configurable threshold
- up to four interrupts when the temperature has fallen below a
configurable threshold

Depending on the IP version, TSENS supports upper, lower and critical
threshold interrupts. We only add support for upper and lower threshold
interrupts for now.

TSENSv2 has an irq [status|clear|mask] bit tuple for each sensor while
earlier versions only have a single bit per sensor to denote status and
clear. These differences are handled transparently by the interrupt
handler. At each interrupt, we reprogram the new upper and lower threshold
in the .set_trip callback.

Amit Kucheria 8b71bce407 drivers: thermal: tsens: Get rid of id field in tsens_sensor
There are two fields - id and hw_id - to track what sensor an action was
to performed on. This was because the sensors connected to a TSENS IP
might not be contiguous i.e. 1, 2, 4, 5 with 3 being skipped.

This causes confusion in the code which uses hw_id sometimes and id
other times (tsens_get_temp, tsens_get_trend).

Switch to only using the hw_id field to track the physical ID of the
sensor. When we iterate through all the sensors connected to an IP
block, we use an index i to loop through the list of sensors, and then
return the actual hw_id that is registered on that index.

Rafael J. Wysocki 3000ce3c52 cpufreq: Use per-policy frequency QoS
Replace the CPU device PM QoS used for the management of min and max
frequency constraints in cpufreq (and its users) with per-policy
frequency QoS to avoid problems with cpufreq policies covering
more then one CPU.

Namely, a cpufreq driver is registered with the subsys interface
which calls cpufreq_add_dev() for each CPU, starting from CPU0, so
currently the PM QoS notifiers are added to the first CPU in the
policy (i.e. CPU0 in the majority of cases).

In turn, when the cpufreq driver is unregistered, the subsys interface
doing that calls cpufreq_remove_dev() for each CPU, starting from CPU0,
and the PM QoS notifiers are only removed when cpufreq_remove_dev() is
called for the last CPU in the policy, say CPUx, which as a rule is
not CPU0 if the policy covers more than one CPU.  Then, the PM QoS
notifiers cannot be removed, because CPUx does not have them, and
they are still there in the device PM QoS notifiers list of CPU0,
which prevents new PM QoS notifiers from being registered for CPU0
on the next attempt to register the cpufreq driver.

The same issue occurs when the first CPU in the policy goes offline
before unregistering the driver.

After this change it does not matter which CPU is the policy CPU at
the driver registration time and whether or not it is online all the
time, because the frequency QoS is per policy and not per CPU.

Linus Walleij 6c375eccde thermal: db8500: Rewrite to be a pure OF sensor
This patch rewrites the DB8500 thermal sensor to be a
pure OF sensor, so that it can be used with thermal zones
defined in the device tree.

This driver was initially merged before we had generic
thermal zone device tree bindings, and now it gets
modernized to the way we do things these days.

The old driver depended on a set of trigger points
provided in the device tree or platform data to
interpolate the current temperature between trigger
points depending on whether the trend was rising or
falling. This was bad because the trigger points should
be used for defining temperature zone policies and
bind to cooling devices.

As the PRCMU (power reset control management unit) can
only issue IRQs when we pass temperature trigger points
upward or downward We instead define a number of
temperature points inside the driver ranging from
15 to 100 degrees celsius. The effect is that when
we register the device we quickly trigger 15, 20 ... up
to the room temperature in succession and then we
get continous event IRQs also under normal operating
conditions, and the temperature of the system is now
reported more accurately (+/- 2.5 degrees celsius)
while in the past the first trigger point was at 70
degrees and the average temperature was simply reported
as 35 degrees celsius (between 70 degrees and 0) until
we passed 70 degrees which didn't accurately represent
the temperature of the system.

As a result of dropping all the trigger points from the
driver and reusing the core DT thermal zone management
code we reduce the code footprint quite a bit.

Ido Schimmel 1851799e1d thermal: Fix use-after-free when unregistering thermal zone device
thermal_zone_device_unregister() cancels the delayed work that polls the
thermal zone, but it does not wait for it to finish. This is racy with
respect to the freeing of the thermal zone device, which can result in a
use-after-free [1].

Fix this by waiting for the delayed work to finish before freeing the
thermal zone device. Note that thermal_zone_device_set_polling() is
never invoked from an atomic context, so it is safe to call
cancel_delayed_work_sync() that can block.

Stefan Mavrodiev 8c7aa18428 thermal_hwmon: Sanitize thermal_zone type
When calling thermal_add_hwmon_sysfs(), the device type is sanitized by
replacing '-' with '_'. However tz->type remains unsanitized. Thus
calling thermal_hwmon_lookup_by_type() returns no device. And if there is
no device, thermal_remove_hwmon_sysfs() fails with "hwmon device lookup
failed!".

The result is unregisted hwmon devices in the sysfs.

Daniel Lezcano 82e430a6df cpuidle: play_idle: Increase the resolution to usec
The play_idle resolution is 1ms. The intel_powerclamp bases the idle
duration on jiffies. The idle injection API is also using msec based
duration but has no user yet.

Unfortunately, msec based time does not fit well when we want to
inject idle cycle precisely with shallow idle state.

In order to set the scene for the incoming idle injection user, move
the precision up to usec when calling play_idle.

Linus Torvalds f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

Daniel Lezcano 57c5b2ec90 thermal/drivers/core: Use governor table to initialize
Now that the governor table is in place and the macro allows to browse the
table, declare the governor so the entry is added in the governor table
in the init section.

The [un]register_thermal_governors function does no longer need to use the
exported [un]register thermal governor's specific function which in turn
call the [un]register_thermal_governor. The governors are fully
self-encapsulated.

The cyclic dependency is no longer needed, remove it.

Daniel Lezcano 980af75ede thermal/drivers/core: Add init section table for self-encapsulation
Currently the governors are declared in their respective files but they
export their [un]register functions which in turn call the [un]register
governors core's functions. That implies a cyclic dependency which is
not desirable. There is a way to self-encapsulate the governors by letting
them to declare themselves in a __init section table.

Define the table in the asm generic linker description like the other
tables and provide the specific macros to deal with.
