Code for a Polling Linux Device Driver
 

Hi all,

I am in the process of writing a polling device driver for a WinTV-Pro 150 TV card. I have source code for an interrupt driver for this code but am trying to implement a polling driver as part of an analysis between these two types of drivers (interrupt and polling).
I have been searching forums and sites looking for information regarding the polling aspect but have found nothing except small paragraphs discussing the the theory behind polling (no sample source code or polling driver functions).
Can anyone point me in the direction of a good site for learning more about how to write polling drivers or have any opinions themselves?

Thanks,
John.
