Linux 6.12 To Enhance The Hybrid P/E Core Experience On Intel Lunar Lake
The work written about earlier this year on New Intel Linux Patches Continue Working To Improve Hybrid CPU Task Placement looks like it will be merged for the upcoming Linux 6.12 cycle as the patches have now been queued into the power management subsystem's '-next' branch
Intel engineer and Linux power management subsystem maintainer Rafael Wysocki explains there:"In order be able to compute the sizes of tasks consistently across all CPUs in a hybrid system, it is necessary to provide CPU capacity scaling information to the scheduler via arch_scale_cpu_capacity(). In order to avoid adding measurable overhead for non-hybrid x86 systems, which are the vast majority in the field, whether or not the new hybrid CPU capacity scaling will be in effect is controlled by a static key. With these hybrid improvements plus Lunar Lake Xe2 graphics enabled by default with the upcoming v6.12 cycle, it's looking like Linux 6.12 will be the baseline for these next-gen Intel laptops.
