This file displays a list of all modules loaded into the kernel. Its contents vary based on the configuration and use of your system, but it should be organized in a similar manner to this sample /proc/modules file output:

~$cat /proc/modules rfcomm 53664 8 - Live 0x00000000bnep 18895 2 - Live 0x00000000uvcvideo 71309 0 - Live 0x00000000videobuf2_vmalloc 13048 1 uvcvideo, Live 0x00000000videobuf2_memops 13170 1 videobuf2_vmalloc, Live 0x00000000videobuf2_core 39258 1 uvcvideo, Live 0x00000000videodev 108503 2 uvcvideo,videobuf2_core, Live 0x00000000

The first column contains the name of the module.

The second column refers to the memory size of the module, in bytes.

The third column lists how many instances of the module are currently loaded. A value of zero represents an unloaded module.

The fourth column states if the module depends upon another module to be present in order to function, and lists those other modules.

The fifth column lists what load state the module is in:

Live,

Loading, or

Unloading are the only possible values.

The sixth column lists the current kernel memory offset for the loaded module. This information can be useful for debugging purposes, or for profiling tools such as

oprofile.

• 第一列： 模块的名字
• 第二列： 模块的内存大小，单位是bytes
• 第三列： 被load的次数，0以为着没有被load过
• 第四列： 是否依赖第三方moudle，列出这些module
• 第五列： 模块的状态，有Live， Loading， Unloading三种状态
• 第六列： 模块当前的内核内存偏移位置。这些信息，debug的时候会非常有用。例如一些诊断工具 oprofile。

/proc/modules :模块加载列表,insmod（加载模块）后在此添加一行。
