LDT project is useful for Linux driver development beginners and as starting point for a new drivers. The driver uses following Linux facilities: module, platform driver, file operations (read/write, mmap, ioctl, blocking and nonblocking mode, polling), kfifo, completion, interrupt, tasklet, work, kthread, timer, simple misc device, multiple char devices, Device Model, configfs, UART 0x3f8, HW loopback, SW loopback, ftracer.

Usage:

Just run

git clone git://github.com/makelinux/ldt.git && cd ldt && make && ./ldt-test && sudo ./misc_loop_drv_test

and explore sources.

Files:

Main source file of LDT: ldt.c

Test script, run it: ldt-test

Generic testing utility for Device I/O: dio.c

Simple misc driver with read, write, fifo, tasklet and IRQ: misc_loop_drv.c
