三大Linux command查看CPU和Memory的使用情况 1. top command :是linux下常用的性能分析工具,能够实时显示系统中各个进程的资源占用状况。 2. free command : free -m查看内存占用情况 free -S不间断地监控有多少内存在使用 --- For example : total used free shared buffers cached Mem: 128 119 8 0 1 22...
On linux, there are commands for almost everything, because the gui might not be always available. When working on servers only shell access is available and everything has to be done from these commands. So today we shall be checking the commands that can be used to check memory usage on...

CMA区域的创建有两种方法,一种是通过dts的reserved memory,另外一种是通过command line参数和内核配置参数。 dts方式: reserved-memory { /* global autoconfigured region for contiguous allocations */ linux,cma { compatible = "shared-dma-pool";
