ARM Hotplug

ARM hotplug refers to the ability to dynamically add or remove processing cores from an ARM-based system-on-chip (SoC) without the need for a system reboot. This feature can help improve power efficiency and performance by allowing the system to allocate resources only when needed.

Hotplugging can be done at the hardware or software level. Hardware hotplugging involves physically adding or removing a processing core from the SoC, while software hotplugging involves activating or deactivating a core through software commands.

ARM hotplugging is commonly used in mobile devices, such as smartphones and tablets. It can also be used in high-performance computing and server environments to optimize resource utilization.
