Help reqd for device driver on sun-sparc 5's

Post by Mangesh Kasbeka » Thu, 08 Feb 1996 04:00:00



Hi !

        We are facing a problem writing a device driver for a FORE ATM
        card for Sun-Sparc 5. Does anybody know an answer to the
        following questions ?

        1. How to make a data segment noncacheable ?
        2. How to invalidate/discard a cache block corresponding to the
           given memory address ? ( Not flush )

        Any help in this regard will be highly appreciated.

Thanx,
Mangesh and Manjunath
