** Summary changed:

- Backport thermald 2.5.8 to noble to support Intel Lunar Lake and Arrow Lake 
CPUs
+ Update thermald in noble to support Intel Lunar Lake and Arrow Lake CPUs

** Summary changed:

- Update thermald in noble to support Intel Lunar Lake and Arrow Lake CPUs

** Description changed:

  [ Impact ]
  
-  * This is a version bump of thermald to 2.5.8, that can support Intel
- Core Ultra Processors (Series 2), aka Lunar Lake and Arrow Lake
- 
-  * This version bump also removes modem support for Intel Atom x3, aka
- SoFIA 3G R, and the power control support of the AMD GPU part of Intel
- 8xxxG, aka Kaby Lake G.
+  * This is an update of thermald in noble to support Intel Core Ultra
+ Processors (Series 2), aka Lunar Lake and Arrow Lake
  
  [ Test Plan ]
  
- (as far as we know, we have no Kaby Lake G nor SoFIA 3G R units in our
- labs. it could be tricky if we also need to handle such case.  We
- received confirmation from upstream (Intel) that the code removal should
- not affect Kaby Lake G units currently on the market including Intel NUC
- and laptops/convertibles.  As for SoFIA 3G R, these SoCs are sold as
- Android phones/tablets from 2015.)
- 
- Pick each of the Kaby Lake, Coffee Lake, Comet Lake, Tiger Lake, Alder
- Lake, Raptor Lake, Lunar Lake, and Arrow Lake systems and run the
- following tests:
+ Pick each of the Alder Lake, Raptor Lake, Lunar Lake, and Arrow Lake
+ systems and run the following tests:
  
  1. Run stress-ng, and observe the temperature/frequency/power with s-tui
    - Temperatures should stay just below trip values
    - Power/performance profiles should stay roughly the same between old 
thermald and new thermald (unless specifically expected eg: to fix 
premature/insufficient throttling)
  2. check if thermald could read rules from /dev/acpi_thermal_rel and generate 
the xml file on /etc/thermald/ correctly.
    - this depends on if acpi_thermal_rel exist.
    - if the machine suppots acpi_thermal_rel, the "thermal-conf.xml.auto"
   could be landed in etc/thermald/.
    - if not, the user-defined xml could be created, then jump to (3).
    - run thermald with --loglevel=debug, and compare the log with xml.auto 
file. check if the configuration could be parsed correctly.
  3. check if thermal-conf.xml and thermal-cpu-cdev-order.xml can be loaded 
correctly.
    - run thermald with --loglevel=debug, and compare the log with xml files.
    - if parsed correctly, the configurations from XML files would appear in 
the log.
  
  [ Where problems could occur ]
  
   * The above test failed, which means the support for Lunar Lake and
- Arrow Lake are incomplete, or regression happened on the supported units
- 
-  * Removing support for Kaby Lake G and SoFIA 3G R actually caused
- issues that upstream did not consider
- 
-  * Other issues caused by bugfix, feature and refactor commits in
- between.
+ Arrow Lake are incomplete, or regression happened on the supported
+ units.
