Public bug reported:
[ 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.
[ 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:
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.
