hi all,
in input.c file in linux kernel 3.2, there is a function add_input_randomness(type, code, value) used when data is post by touchscreen driver ti_tsc.c (exemple : input_report_abs(input_dev, ABS_PRESSURE, z).
Do you know what it used to ?
thanks
Hi Gaudichon,
This question is a very narrowed one.
My suggestion for you is
1. To do a code walk through and understand what it does.
Use code browser.
It is defined in the following path.
drivers/char/random.c
"add_input_randomness()" uses the input layer interrupt timing as well as the event type information from the hardware.
By the way, which TI processor you use?
Regards,
Shankari
