sysace device driver question

Hi all,

I would like to know in what manner the sysace device driver was implemented for

the xup Virtex II pro.

Does anyone know if the technique used to monitor the end of I/O operation is "polling mode" 

or "Interrupt mode".

 

I want to knkow this, because I need to measure time spent by a task reading  or writing data

to the compact flash.

 

Thanks a lot

Re: sysace device driver question

The newest driver uses interrupts, not sure on the older driver but there's no reason to use the older driver to my knowledge.  You can see it also at drivers/block/sysace.c.
