Subject: Cache Enabling.
Date: Mon, 11 Nov 2002 15:06:58 +0530 (IST) [thread overview]
Message-ID: <Pine.LNX.4.21.0211111454430.16030-100000@deepesh.india.tejasnetworks.com> (raw)
Dear All,
I am using Power PC. The system which I am using takes 2 minutes more than
usual for the software in the system to come up without cache
enabling. These 2 minutes are really crucial.
But there are problems when I enabled cache. The devices which I am using
are mmapped. I do not want cache to be enabled for the memory mapped
devices. When cache is enabled, none of the mmapped devices work in the
usual way. How do I selectively disable the cache for the mmapped devices?
Thank you,
Deepesh
