When Intel launched the 12th generation Core processor at the end of last year, it stressed that it was necessary to upgrade Microsoft's latest Win11 system, the reason is that the 12th generation Core first used the heterogeneous design of the performance core + energy efficiency core, which is commonly known as the size of the core, only the Win11 system has been optimized accordingly.
Two different CPU cores involve a responsible scheduling system, for which Intel has specially designed intel thread director (thread scheduler), and deeply integrated with Windows 11, to ensure that different loads are distributed to the most appropriate core under different conditions.
The 12th generation Core hardware integrates a microcontroller to monitor the runtime instructions of each thread with nanosecond accuracy, feedback to the operating system in real time for the most appropriate dispatch scheduling, and dynamically adapt to the thermal design, operating environment, power consumption settings, etc., all without user intervention.
The problem is that now only the Win11 system supports the 12th generation of Core thread scheduler, the Linux system does not support, fortunately Intel has noticed this problem, from the end of last year also cooperated with the Linux community to let the Linux kernel support the thread scheduler, it is expected to add size kernel optimization features in the 5.18 kernel.
The Linux 5.18 kernel is still in development and is expected to be released in the spring of 2022, waiting for the Linux community to announce it.
