* [https://github.com/makelinux/ldt/ LDT - Linux Driver Template] - sample template of Linux device driver for learning and starting source for a custom driver. Implements UART char device driver for example. 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, misc device, proc fs, UART 0x3f8, HW loopback, SW loopback, ftracer. The code is in working condition and runs with test script.
