Message-ID: <20010501191111.A93807@pepcross.demon.co.uk> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Noting the new(ish) CPUTYPE option in make.conf I see that k7 defaults to setting options for k6 in gcc. (just made world for 4.3-Release using CPUTYPE=k7) I assume this was carefully thought out and that it possibly shouldn't default to optimising for pentiumpro instead. (or should it, frankly I don't understand why the choice was k6 opts instead of ppro opts, I assume k6 opts work better, but I've not tested it in depth yet.) However.. in the kernel config file I've always specified the athlon as a 686 class CPU. This seems inconsistent. Would anyone care to explain why the difference in how Athlons are treated, between kernel config and make.conf. Or should my kernel config have I586_CPU instead of I686_CPU. (I assume it wouldn't boot that way, but I've not tried it.) Thanks, Steve Roome To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
