Hi All,
why there is no character device entry present in /sys/class? where as block and net device entries are present.
I see character devices there, but not the device nodes. I don't see block device nodes there either.
Not only in /sys/class, for that matter why there is no character device entries present in /sys file system.
What do you exactly mean by "character device entries"?
please help me to understand for what purpose char devices are kept away from / sys file system.
Have you read the driver model chapter in the Linux Device drivers book, or the in-kernel sysfs documentation? thanks, greg k-h
