我很难弄清楚 Android 4.0.3 的 lsmod 输出。所有这些“实时地址”条目是什么意思？

我问这个是因为我使用完全相同的内核来启动 Ubuntu，这是 lsmod 在 Ubuntu 上的输出

HDMI、Camera 等无法在 Ubuntu 上运行，尽管在两个操​​作系统上都加载了相同的模块。这就是我询问 Live 和 ADDR 列的原因。我想知道这是否与 Ubuntu 缺乏功能有关。

lsmod只是从文件中读取/proc/modules（它实际上调用 cat /proc/modules）

这对于许多类似 UNIX 的操作系统来说都是一样的：

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.
