/proc/meminfo中的条目 [英] Entries in /proc/meminfo

问题描述

我可以理解/proc/meminfo 中包含的大多数信息，例如总内存，缓冲区，高速缓存等.您能告诉我那些不太明显的信息(例如以下所列内容)是什么意思吗? ?

I can make sense of most of the information contained in /proc/meminfo like total memory, buffers, cache etc. Could you tell me what do the less obvious ones like the ones listed below mean?

• AnonPages
• 映射
• 平板
• NFS_Unstable
• 弹跳
• VmallocTotal
• VmallocUsed
• VmallocChunk

如果有人想知道，我正在谈论linux命令的输出 cat/proc/meminfo

If anyone is wondering, I am talking about the output of the linux command cat /proc/meminfo

推荐答案

此信息的规范来源为

The canonical source of this information is /usr/src/linux/Documentation/filesystems/proc.txt. Specifically,

   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
