Linux updates improve Raspberry Pi performance and efficiency

Linux kernel updates boost Raspberry Pi efficiency with Suspend-To-Idle and NUMA emulation patches, enhancing performance and power savings.

: Recent Linux updates enhance the Raspberry Pi's performance and efficiency. Two new patches, including Suspend-To-Idle support and NUMA emulation for arm64, improve power savings and memory optimization. These changes result in notable performance gains, particularly for the Raspberry Pi 5.

Recent Linux kernel updates have enhanced the functionality and efficiency of Raspberry Pi devices. The first patch introduces Suspend-To-Idle (s2idle) support for the older ARM-based BCM2835 SoC, providing a minor energy saving that accumulates across millions of units.

The second patch implements NUMA emulation for arm64 platforms, specifically benefiting the Raspberry Pi 5. This patch allows for better memory access parallelism, resulting in a six percent increase in single-core performance and an 18 percent boost in multi-core performance according to Geekbench 6.

Developers Stefan Wahren and others have focused on these updates to improve the Raspberry Pi's compatibility with Linux-based operating systems. Although further steps are needed to fully unlock these performance enhancements, the patches offer a significant improvement in efficiency and power management.
