Intel engineers have been busy working on Linux support for the upcoming Lunar Lake processors. While most core functionality seems to be in good shape, there are some issues related to enabling Xe2 graphics and power management that are still being worked on. Recent patches have been released to enable features such as Digital Linear Voltage Regulator (DLVR) support, processor thermal kills, Workload Hints (WLT), and power floor support.
The DLVR patches aim to optimize energy conservation, while the processor thermal kills and other patches focus on improving power management for Lunar Lake processors. The patches also include revisions for thermal interrupt support and the use of MSI sources for workload type suggestions, DDR thermals, power floor, and package thermals. The patches also introduce Intel Workload Type Tips, which allow users to communicate the type of expected workload, from idle to battery life optimization, sustained performance, burst, or unknown.
These developments suggest that support for Lunar Lake processors is progressing well, with the hope that the int340x driver patches will be included in the upcoming Linux 6.11 kernel merge window. This aligns with the expected release of Intel Core Ultra laptops powered by Lunar Lake processors in the coming months.
Overall, Intel is making steady progress in ensuring that Linux support for Lunar Lake processors is in good shape, with ongoing efforts to address issues related to graphics enablement and power management. Keep an eye out for further updates as these patches are integrated into the Linux kernel.
