Details
cchardev.ko is an AVM module for easy creation of char devices. It is used by some routing related modules from AVM.
These modules depend on cchardev.ko, see the Dependencies, and request the char devices from it they need on load.
cchardev.ko collects the list of wanted devices and provides them at a procfs interface at /proc/cchardevice.
This interface provides a variable amount of files to interact with it, which are listed in cprocfs. By default there are 3.
7520 fw 7.57:
root@fritz1:/var/mod/root# cat /proc/cchardevice/cprocfs cchardevice/ control (control) devices cprocfs root@fritz1:/var/mod/root# ls -l /proc/cchardevice/ -rw-r--r-- 1 root root 0 Dec 18 21:32 control -r--r--r-- 1 root root 0 Dec 18 21:32 cprocfs -r--r--r-- 1 root root 0 Dec 18 21:32 devices
devices provides the list of wanted devices, their major, and the module requesting it.
root@fritz1:/var/mod/root# cat /proc/cchardevice/devices kskbtracepoint 240 (kskbtrace) kdsld 239 (kdsldmod) kavmcounterd 238 (kdsldmod) kvpnd 237 (kdsldmod) kdsldptrace 233 0-33 (kdsldmod) knqos 232 (kdsldmod) avmtrackd 231 (kdsldmod) avmtrackdquery 230 (kdsldmod) userman_url 229 (kdsldmod) bridgeflt 228 (kdsldmod) krextd 227 (kdsldmod) krextd_wlan 226 (kdsldmod)
control is the control interface of the module and it's writable:
root@fritz1:/var/mod/root# cat /proc/cchardevice/control possible commands: addtest deltest
Writing addtest to control adds a test device to devices, deltest removes it.
root@fritz1:/var/mod/root# echo addtest > /proc/cchardevice/control root@fritz1:/var/mod/root# tail -n 1 /proc/cchardevice/devices cchardevice_test 222 0-2 (cchardev)
The collected wanted devices are not created by this module but in userspace by ewnw_devfiles.sh.
For this script two extra procfs files are created after all dependingd modulea are loaded.
mknod-parameterslists the name, type, major and minor of each device file to createremovelists the name of each device file to remove
Once ewnw_devfiles.sh added and removed all devices it sends cleanup to control to remove the .extra procfs files.
GPL-Browser
Daily updated index of all cchardev.ko code findings on the GPL-Browser. Last update: 2024-11-15 05:07 GMT.
The Files header attempts to list the files which belong to this module. Useful if a directory contains multiple modules.
The Browse column points to the Path of the Makefile referring this code on the gpl.boxmatrix.info service.
The SoC column lists the Chip-Codenames, the Model column lists the nicks of the Box-Models.
The Diff column links the comparison of the AVM Kernel to the pristine original from Kernel.org.
The Download column links the full tarball the respective directory content is extracted from.
The presence of the source does not mean it fits the respective model and architecture. See the Model-Matrix where it's used.
Note that this list matches module names with hyphen (-) and underscore (_) exchangeable, same as modprobe does.
