membank meminfo 初始化
转: Documentation/filesystems/proc.txt meminfo zh_cn: Provides information about distribution and utilization of memory. This varies by architecture and compile options. The following is from a 16GB PIII, which has highmem enabled. You may not have all of these fields. MemTotal: 所有可用RAM大小 （即物理内存减去一些预留位和内核的二进制代码大小） MemFree: LowFree与HighFree的总和 ...

/proc/meminfo This is one of the more commonly used files in the /proc/ directory, as it reports a large amount of valuable information about the systems RAM usage. The following sample /proc/meminfo virtual file is from a system with 256 MB of RAM and 512 MB of swap space: MemTotal: 255908 kB MemFree: 69936 kB Buffers: 15812 kB Cached: 115124 kB SwapCached: ...
我在/proc/meminfo下面看到了一些数据。[code]MemTotal: 2034284 kB MemFree: 474328 kB Buffers: 53728 kB Cached: 1178776 kB SwapCached: 460 kB Active: 747908 kB Inactive: 730640 kB Active(anon): 232864 kB Inactive(anon): 81168 kB Active(file): 515044 kB Inactive(file): 649472 kB Unevictable: 0 kB Mlocked: ...
看/proc/meminfo，有个问题不解。 就是MemTotal由/proc/meminfo里的哪些部分组成？ 我个人理解，Memtotal=Memfree+buffers+caches+Anonpages+Slab+Pagetables+VMallocused? 但是好多系统往往这个等号不成立，往往等号左边大于右边，而且有的机器相差还很大。 是否某些内存的使用没有统计在meminfo里面？ 请高手指点。谢谢！

上篇文章对meminfo里的信息做出简单的解释了那么内核怎么把meminfo信息动态反应到meminfo文件中呢在内核 linux/fs/proc/proc_misc.c中 static int meminfo_read_proc(char *page, char **start, off_t off, int count, int *eof, void *data) { struct sysinfo i; int len; unsigned long committed; unsigned long allowed; ...
主要参考内核文档和红帽文档对 > cat /proc/meminfo 读出的内核信息进行解释， 下篇文章会简单对读出该信息的代码进行简单的分析。MemTotal: 507480 kB MemFree: 10800 kB Buffers: 34728 kB Cached: 98852 kB SwapCached: 128 kB Active: 304248 kB Inactive: 46192 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 507480 kB LowFree: ...
