Dynamic circular Queue with IOctl calls support.

Building

$ make

to build the kernel module (mydriver.c)

$ gcc config.c -o config

$ gcc fill.c -o fill

$ gcc read.c -o read

to build userspace programs.

Usage

After building the Kernel module and userspace programs

Load the Kernel module:

$ sudo insmod mydriver.ko

Run the configuration program, it initialises the dynamic circular queue in the Kernel space with specified capacity:

$ ./config

Push some data on to the queue:

$ ./fill

Running this program multiple times adds more elements to the queue, and fails on overflow.

Pop data from the queue:

$ ./read

Running this program should print the data popped from the queue. It fails in case of underflow.

Tested on Linux Kernel 6.10.7
