What: /sys/module
|
Description:
|
The /sys/module tree consists of the following structure:
|
|
/sys/module/MODULENAME
|
The name of the module that is in the kernel. This
|
module name will always show up if the module is loaded as a
|
dynamic module. If it is built directly into the kernel, it
|
will only show up if it has a version or at least one
|
parameter.
|
|
Note: The conditions of creation in the built-in case are not
|
by design and may be removed in the future.
|
|
/sys/module/MODULENAME/parameters
|
This directory contains individual files that are each
|
individual parameters of the module that are able to be
|
changed at runtime. See the individual module
|
documentation as to the contents of these parameters and
|
what they accomplish.
|
|
Note: The individual parameter names and values are not
|
considered stable, only the fact that they will be
|
placed in this location within sysfs. See the
|
individual driver documentation for details as to the
|
stability of the different parameters.
|
|
/sys/module/MODULENAME/refcnt
|
If the module is able to be unloaded from the kernel, this file
|
will contain the current reference count of the module.
|
|
Note: If the module is built into the kernel, or if the
|
CONFIG_MODULE_UNLOAD kernel configuration value is not enabled,
|
this file will not be present.

Description: This read-only file will appear if modpost was supplied with an
|
SCM version for the module. It can be enabled with the config
|
MODULE_SCMVERSION. The SCM version is retrieved by
|
scripts/setlocalversion, which means that the presence of this
|
file depends on CONFIG_LOCALVERSION_AUTO=y. When read, the SCM
|
version that the module was compiled with is returned. The SCM
|
version is returned in the following format::
