Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-linux-mips@oss.sgi.com Precedence: bulk Return-Path: X-Orcpt: rfc822;linux-mips-outgoing Ralf, Is there is easy way to turn off caching entirely? I understand I need to set k0 bits in config register. What about those C bits in TLB entries? My CPU only has primary cache. I am running into some weired crashing problems, which makes me suspect about the cache code that I modified ... Thanks. (BTW, thanks for the info on strace files.) Jun
