When we register a driver, the "name" parameter shows up in /proc/devices, yet we can write to the devices using the entry in /dev corresponding to the device. What are the core ideas behind /proc and /dev entries? Moving further, is sysfs supposed to be a replacement for procfs? How does it differ from procfs?


/proc/devices - List of device drivers configured into the currently running kernel (block and character)

/dev - This directory contains the special device files for all the devices

Difference between procfs vs sysfs
