** 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 + [SRU] patch 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. ** Patch added: "thermald_2.5.6-2ubuntu0.24.04.1.debdiff" https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/2087816/+attachment/5836525/+files/thermald_2.5.6-2ubuntu0.24.04.1.debdiff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2087816 Title: [SRU] patch thermald in noble to support Intel Lunar Lake and Arrow Lake CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/2087816/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
