Pull thermal control updates from Rafael Wysocki:
 "These further rework the ACPI thermal driver, after the changes made
  to it in the previous cycle, to make it easier to grasp, get rid of
  redundant pieces of internal data structures and eliminate its
  reliance on a specific ordering of trip point objects in the thermal
  core, make thermal core adjustments needed for the ACPI thermal driver
  rework, modify the thermal governor interface so as to use trip
  pointers for representing trip points in it, switch over multiple
  thermal drivers to using void platform driver remove callbacks, add
  support for 2 hardware features to the Intel int340x thermal driver,
  add support for new hardware on ARM platforms, update documentation,
  fix problems, clean up code and update the MAINTAINERS record for
  thermal control.

It is not necessary to include thermal_core.h into thermal_acpi.c,
because none of the code in there depends on anything in the former,
except for the linux/thermal.h, but it is better to include that one
directly instead of including the entire thermal_core.h, so make that
change.

No functional impact.

thermal: core: Don't update trip points inside the hysteresis range 2023-10-20T17:26:37+00:00 Nícolas F. R. A. Prado nfraprado@collabora.com 2023-09-22T18:44:03+00:00 cf3986f8c01d355490d0ac6024391b989a9d1e9d When searching for the trip points that need to be set, the nearest higher trip point's temperature is used for the high trip, while the nearest lower trip point's temperature minus the hysteresis is used for the low trip. The issue with this logic is that when the current temperature is inside a trip point's hysteresis range, both high and low trips will come from the same trip point. As a consequence instability can still occur like this: * the temperature rises slightly and enters the hysteresis range of a trip point * polling happens and updates the trip points to the hysteresis range * the temperature falls slightly, exiting the hysteresis range, crossing the trip point and triggering an IRQ, the trip points are updated * repeat So even though the current hysteresis implementation prevents instability from happening due to IRQs triggering on the same temperature value, both ways, it doesn't prevent it from happening due to an IRQ on one way and polling on the other. To properly implement a hysteresis behavior, when inside the hysteresis range, don't update the trip points. This way, the previously set trip points will stay in effect, which will in a way remember the previous state (if the temperature signal came from above or below the range) and therefore have the right trip point already set. The exception is if there was no previous trip point set, in which case a previous state doesn't exist, and so it's sensible to allow the hysteresis range as trip points.

When searching for the trip points that need to be set, the nearest
higher trip point's temperature is used for the high trip, while the
nearest lower trip point's temperature minus the hysteresis is used for
the low trip. The issue with this logic is that when the current
temperature is inside a trip point's hysteresis range, both high and low
trips will come from the same trip point. As a consequence instability
can still occur like this:
* the temperature rises slightly and enters the hysteresis range of a
  trip point
* polling happens and updates the trip points to the hysteresis range
* the temperature falls slightly, exiting the hysteresis range, crossing
  the trip point and triggering an IRQ, the trip points are updated
* repeat

So even though the current hysteresis implementation prevents
instability from happening due to IRQs triggering on the same
temperature value, both ways, it doesn't prevent it from happening due
to an IRQ on one way and polling on the other.

To properly implement a hysteresis behavior, when inside the hysteresis
range, don't update the trip points. This way, the previously set trip
points will stay in effect, which will in a way remember the previous
state (if the temperature signal came from above or below the range) and
therefore have the right trip point already set.

The exception is if there was no previous trip point set, in which case
a previous state doesn't exist, and so it's sensible to allow the
hysteresis range as trip points.
