Hi I develop template of Linux driver. It can be used as sample for Linux driver development beginners and starting point for development of new drivers. The driver uses following Linux facilities: module, platform driver, file operations (read/write, mmap, ioctl, blocking and non-blocking mode, polling), kfifo, completion, interrupt, tasklet, work, kthread, timer, misc device, proc fs, UART 0x3f8, HW loopback, SW loopback Readme and sources: https://github.com/makelinux/ldt/blob/master/README.md To run driver with test script just run: git clone git://github.com/makelinux/ldt.git && cd ldt && ./ldt-test You feedback, suggestions, discussions, recommendations patched will be greatly appreciated!
