** 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. [ 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 one of Alder Lake, one of Raptor Lake, one of Lunar Lake, one of - Arrow Lake systems and run the following tests: + 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.
