[ts-7000] SPI Interrupt Handler

["grady_sean" <>]

Hello all, I have been trying to compile a kernel with RTAI support
but am having issues. I am wondering if I am barking up the wrong tree.

All I need to do is write a SPI driver to recieve data and shove it
somewhere, like a flat text file, for later processing. 

I thought I would need to hook into the SPI RX interrupt to do this,
and that is how I found out about the RTAI API.

However, I wonder if I am over-complicating things?

In the files section, I found 'gps_pps.tgz' and it does not use the
RTAI API calls.

They include <linux/interrupt.h> among other things, and appear to
call 'request_irq()' among other things to manipulate.

Does anyone have any guidance or advice on which approach I should be
taking?
