假设传入的cpu编号为65,get_cpu_mask()函数处理如下: /* 初始值还是cpu_bit_bitmap[2] */constunsignedlong*p=cpu_bit_bitmap[1+1];/* 因指针p指向的数据类型为unsigned long型,所以此处p指向的地址* 需减去1*sizeof(unsigned long),64为系统中即为8*/p-=1;returnto_cpumask(p); 返回的cpumask如图...
cpumask: powerpc: Introduce cpumask_of_{node,pcibus} to replace {node,pcibus}_to_cpumask Impact: New APIs The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack. (Also replaces powerpc int...

A thread affinity mask must be a proper subset of the process affinity mask for the containing process of a thread. A thread is only allowed to run on the processors its process is allowed to run on.通过调用SetThreadAffinityMask，就能为各个线程设置亲缘性屏蔽：DWORD_PTR SetThread...
例如,使用C++代码对任意线程进行绑定,使用的参数依次是目标线程ID和目标CPU ID。 cpp int bindThreadToCPU(const int threadId, const int cpuNumber) { cpu_set_t mask; CPU_ZERO(&mask); CPU_SET(cpuNumber, &mask); return sched_setaffinity(threadId, sizeof(mask), &mask); }...
