keyboard按键中断驱动
########## # README # ########## Purpose ------- To help understand which is the most commonly 'pressed' and 'released' key in the keyboard. Holding a key down will generate 'pressed' events more so, count of pressing need not be equal to release count. (This code works only for ps/2 keyboards, not usb which generates interrupt in different IRQ line.) How To Use ---------- Please don't proceed if you see any error in the below steps. 0. 0rth Law (as in thermodynamics) cat LICENSE 1. compile a. create the header files $ make header ( sometimes the above may not work, as it won't be able to get file descriptor. please run as sudo $ sudo make header ) b. compile the source $ make 2. Insert the module into kernel and setup the system $ keyboard_stats_load 3. Read the statistics $ cat /dev/keyboard_stats 4. Remove the module and system $ keyboard_stats_unload 5. Cleaning the dir $ make clean DEBUGGING --------- Mail the author or read /var/log/messages and try your luck by setting the scancodes etc. Misc ---- I wrote this code because few of my keys are more shiny than others and i had to find out why!! :-) Bugs ---- In my MAC VM, some keys were not working, like arrow keys!
