thermal: intel: hfi: Add syscore callbacks for system-wide PM

thermal: intel: hfi: Add syscore callbacks for system-wide PM

[ Upstream commit 97566d09fd02d2ab329774bb89a2cdf2267e86d9 ]

The kernel allocates a memory buffer and provides its location to the
hardware, which uses it to update the HFI table. This allocation occurs
during boot and remains constant throughout runtime.

When resuming from hibernation, the restore kernel allocates a second
memory buffer and reprograms the HFI hardware with the new location as
part of a normal boot. The location of the second memory buffer may
differ from the one allocated by the image kernel.

When the restore kernel transfers control to the image kernel, its HFI
buffer becomes invalid, potentially leading to memory corruption if the
hardware writes to it (the hardware continues to use the buffer from the
restore kernel).

It is also possible that the hardware "forgets" the address of the memory
buffer when resuming from "deep" suspend. Memory corruption may also occur
in such a scenario.

To prevent the described memory corruption, disable HFI when preparing to
suspend or hibernate. Enable it when resuming.

Add syscore callbacks to handle the package of the boot CPU (packages of
non-boot CPUs are handled via CPU offline). Syscore ops always run on the
boot CPU. Additionally, HFI only needs to be disabled during "deep" suspend
and hibernation. Syscore ops only run in these cases.

thermal: intel: hfi: Disable an HFI instance when all its CPUs go offline

[ Upstream commit 1c53081d773c2cb4461636559b0d55b46559ceec ]

In preparation to support hibernation, add functionality to disable an HFI
instance during CPU offline. The last CPU of an instance that goes offline
will disable such instance.

The Intel Software Development Manual states that the operating system must
wait for the hardware to set MSR_IA32_PACKAGE_THERM_STATUS[26] after
disabling an HFI instance to ensure that it will no longer write on the HFI
memory. Some processors, however, do not ever set such bit. Wait a minimum
of 2ms to give time hardware to complete any pending memory writes.

In preparation for the addition of a suspend notifier, wrap the logic to
enable HFI and program its memory buffer into helper functions. Both the
CPU hotplug callback and the suspend notifier will use them.

This refactoring does not introduce functional changes.

Merge tag 'thermal-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
"The majority of changes here are related to the general switch-over to
using arrays of generic trip point structures registered along with a
thermal zone instead of trip point callbacks (this has been done
mostly by Daniel Lezcano with some help from yours truly on the Intel
drivers front).

Apart from that and the related reorganization of code, there are some
enhancements of the existing driver and a new Mediatek Low Voltage
Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
rework so it will use the generic idle_inject facility for CPU idle
time injection going forward and it will take additional module
parameters for specifying the subset of CPUs to be affected by it
(work done by Srinivas Pandruvada).

Also included are assorted fixes and a whole bunch of cleanups.

Specifics:

- Rework a large bunch of drivers to use the generic thermal trip
structure and use the opportunity to do more cleanups by removing
unused functions from the OF code (Daniel Lezcano)

- Remove core header inclusion from drivers (Daniel Lezcano)

- Fix some locking issues related to the generic thermal trip rework
(Johan Hovold)

- Fix a crash when requesting the critical temperature on tegra,
which is related to the generic trip point work (Jon Hunter)

- Clean up thermal device unregistration code (Viresh Kumar)

- Fix and clean up thermal control core initialization error code
paths (Daniel Lezcano)

- Relocate the trip points handling code into a separate file (Daniel
Lezcano)

- Make the thermal core fail registration of thermal zones and
cooling devices if the thermal class has not been registered
(Rafael Wysocki)

- Add trip point initialization helper functions for ACPI-defined
trip points and modify two thermal drivers to use them (Rafael
Wysocki, Daniel Lezcano)

- Make the core thermal control code use sysfs_emit_at() instead of
scnprintf() where applicable (ye xingchen)

- Consolidate code accessing the Intel TCC (Thermal Control
Circuitry) MSRs by introducing library functions for that and
making the TCC-related code in thermal drivers use them (Zhang Rui)

- Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
changes (Zhang Rui)

- Address an "unsigned expression compared with zero" warning in the
intel_soc_dts_iosf thermal driver (Yang Li)

- Update comments regarding two functions in the Intel Menlow thermal
driver (Deming Wang)

- Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
driver (ye xingchen)

- Make the intel_pch thermal driver support the Wellsburg PCH (Tim
Zimmermann)

- Modify the intel_pch and processor_thermal_device_pci thermal
drivers use generic trip point tables instead of thermal zone trip
point callbacks (Daniel Lezcano)

- Add production mode attribute sysfs attribute to the int340x
thermal driver (Srinivas Pandruvada)

- Rework dynamic trip point updates handling and locking in the
int340x thermal driver (Rafael Wysocki)

- Make the int340x thermal driver use a generic trip points table
instead of thermal zone trip point callbacks (Rafael Wysocki,
Daniel Lezcano)

- Clean up and improve the int340x thermal driver (Rafael Wysocki)

- Simplify and clean up the intel_pch thermal driver (Rafael Wysocki)

- Fix the Intel powerclamp thermal driver and make it use the common
idle injection framework (Srinivas Pandruvada)

- Add two module parameters, cpumask and max_idle, to the Intel
powerclamp thermal driver to allow it to affect only a specific
subset of CPUs instead of all of them (Srinivas Pandruvada)

- Make the Intel quark_dts thermal driver Use generic trip point
objects instead of its own trip point representation (Daniel
Lezcano)

- Add toctree entry for thermal documents and fix two issues in the
Intel powerclamp driver documentation (Bagas Sanjaya)

- Use strscpy() to instead of strncpy() in the thermal core (Xu
Panda)

- Fix thermal_sampling_exit() (Vincent Guittot)

- Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam
Chihi)

- Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
Uytterhoeven)

- Fix useless call to set_trips() when resuming in the rcar_gen3
thermal control driver and add interrupt support detection at init
time to it (Niklas Söderlund)

- Fix memory corruption in the hi3660 thermal driver (Yongqin Liu)

- Fix include path for libnl3 in pkg-config file for libthermal
(Vibhav Pant)

- Remove syscfg-based driver for st as the platform is not supported
any more (Alain Volmat)"

thermal: Remove core header inclusion from drivers

As the name states "thermal_core.h" is the header file for the core
components of the thermal framework.

Too many drivers are including it. Hopefully the recent cleanups
helped to self encapsulate the code a bit more and prevented the
drivers to need this header.

Remove this inclusion in every place where it is possible.

Some other drivers did a confusion with the core header and the one
exported in linux/thermal.h. They include the former instead of the
latter. The changes also fix this.

The tegra/soctherm driver still remains as it uses an internal
function which need to be replaced.

The Intel HFI driver uses the netlink internal framework core and
should be changed to prevent to deal with the internals.

No functional changes intended.
