我可以理解 /proc/meminfo 中包含的大部分信息,例如总内存、缓冲区、缓存等。你能告诉我下面列出的那些不太明显的信息是什么意思吗?

  • 匿名页面
  • 映射
  • 楼板
  • NFS_不稳定
  • 弹跳
  • VmallocTotal
  • VmallocUsed
  • VmallocChunk

如果有人想知道,我说的是 linux 命令 cat/proc/meminfo

的输出

最佳答案

此信息的规范来源是 /usr/src/linux/Documentation/filesystems/proc.txt .具体来说,

   AnonPages: Non-file backed pages mapped into userspace page tables
Mapped: files which have been mmaped, such as libraries
Slab: in-kernel data structures cache
NFS_Unstable: NFS pages sent to the server, but not yet committed to stable
storage
Bounce: Memory used for block device "bounce buffers"
VmallocTotal: total size of vmalloc memory area
VmallocUsed: amount of vmalloc area which is used
VmallocChunk: largest contigious block of vmalloc area which is free
