Subject: Cache coherency and snooping
Date: Tue, 13 Aug 2002 16:22:31 -0700	[thread overview]
Message-ID: <0a9a01c24320$4c936de0$9e10a8c0@IMRANPC> (raw)

Hi,

How can I define a certain region of memory so that it is never cached? I
want to use non-cached region of memory to communicate to my PCI device to
avoid system overhead in cache snooping.

Thanks,
Imran.
