CONFIG_FORCE_NR_CPUS: Set number of CPUs at compile time

General informations

The Linux kernel configuration item CONFIG_FORCE_NR_CPUS has multiple definitions:

Set number of CPUs at compile time found in lib/Kconfig

The configuration item CONFIG_FORCE_NR_CPUS:

• prompt: Set number of CPUs at compile time
• type: bool
• depends on: CONFIG_SMP && CONFIG_EXPERT && ! CONFIG_COMPILE_TEST
• defined in lib/Kconfig
• found in Linux kernels: 6.2–6.8, 6.9-rc+HEAD

Say Yes if you have NR_CPUS set to an actual number of possible CPUs in your system, not to a default value. This forces the core code to rely on compile-time value and optimize kernel routines better.
