NR_CPUS是与多处理相关的宏定义，表示CPU的个数。如果定义了CONFIG_SMP那么取CONFIG_NR_CPUS，否则取1。

Hardcoding the number of CPUs at compile time does improve code generation, but if you get it wrong the result will be confusion. We already limited this earlier to only "experts" (see commit fe5759d "cpumask: limit visibility of FORCE_NR_CPUS"), but with distro kernel configs often hav...

Network management in new realms: wireless sensor networks Wireless sensor networks (WSNs) have emerged as a new computing paradigm within the past 6-7 years, spearheading the advent of pervasive computing. The miniaturization of the size and the cost of electronics has allowed visions of multip....
grep NR_CPUS /boot/config-`uname -r` 这个命令会给出内核支持的最大处理器数量,可以通过内核命令行参数nr_cpus进行修改。 要查找在线CPU数量,可以使用num_online_cpus()函数。 那么nr_cpu_ids是什么? #include <linux/kernel.h> #include <linux/module.h> ...
