Therefore, it won’t really help you to determine which process is using too much CPU time or memory. 您已经学会了如何使用ps命令在2.16节“列出和操作进程”中列出系统上运行的进程。 ps命令列出当前进程,但它很少告诉您进程如何随时间变化。 因此,它无法真正帮助您确定哪个进程使用了过多的CPU时间或内存...
外围设备的寄存器通常被连续地编址,处理器对外围设备寄存编址方式分为两种:I/O映射方式( l/O-mapped),内存映射方式(memory-mapped)。 应用程序只能通过虚拟地址访问外设寄存器,内核提供API函数来把外设寄存器的物理地址映射到虚拟地址空间。ARM64 架构(物理地址宽度最大支持48位)分为两种内存类型:...
