CPU & Memory Query about creating sysfs directory under device driver

Hi all,

Currently i am involved in developing a device driver for a custom hardware.

My linux stack already has the sysfs directory structure

/sys/class/hwmon/

My need is that, while loading my device driver i need to create a "xyz" sysfs directory inside hwmon sysfs directory as shown below

/sys/class/hwmon/xyz/

I came across a function called class_create_file call using which we can able to create a sysfs file. But, I don't know about a way to create sysfs directory. Smilie

systool - view system device information by bus, class, and topology SYNOPSIS
systool [options [device]] DESCRIPTION
Calling systool without parameters will present all available bus types, device classes, and root devices. When device is supplied, the information reqested by options is shown only for the specified device, otherwise all present devices are dis- played. systool uses APIs provided by libsysfs to gather information. systool runs only on Linux systems running kernels 2.5 or later, with the sysfs filesystem mounted. OPTIONS
-a Show attributes of the requested resource -b bus Show information for a specific bus -c class Show information for a specific class -d Show only devices -h Show usage -m module_name Show information for a specific module -p Show absolute sysfs path to the resource -v Show all attributes with values -A attribute Show attribute value for the requested resource -D Show only drivers -P Show device's parent SEE ALSO
