[SOLVED] How to creating sysfs directory ?

[cbalu]

Hi all,

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

My linux stack already has the directory structure

/sys/class/hwmon/

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

/sys/class/hwmon/xyz/

How can i do that.Can anyone help me with the kernel function call.

I know about a class_create_file call using which we can able to create a sysfs file.But, I don't know about a way to creating sysfs directory.

have you looked at kobjects?

If you create a kobject (and add it to the sysfs tree), it will end up as a directory, and if you provide the hwmon-kobject as parent, it will be placed as a subdir in /sys/class/hwmon.

To add files, you add attributes.
