Hi everybody,
I am writing device driver for fingerprint sensor.
I have written almost all the driver.
But I encountered a problem :
whenever I perform read on my device like this:
fread(buff,20,1,fp); /* in user space */
Read routine of my device driver is called 20 times.
I dont want it this way, as in a single call I
can pass the whole image buffer to it.
As the image buffer is 76800 bytes , my driver
doesnt responds for minutes.
Please suggest the solution.
Thanks in advance.
