Date: Wed, 21 Apr 1999 18:01:37 +1000 X-Mailer: KMail [version 1.0.17] Content-Type: text/plain MIME-Version: 1.0 Message-Id: <99042118082205.43091@gurney.reilly.home> Content-Transfer-Encoding: 8bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi all, I've been meaning to ask this for a while, but it took the question about the K6-III to goad me into action: I'm currently running FreeBSD-3.1-STABLE on a P-III, and yes, it's damn fast, but it's really just a P-II at this stage, isn't it? Does anyone know of any efforts in the direction of a) tweaking as to understand the new (KNI SIMD float) instructions. b) tweaking cc (egcs) to emit those, if it can (much less likely, my guess) c) tweaking the kernel to save and restore the new state on task switches. I guess that as long as (a) doesn't exist, there won't be any programs using the new instructions or registers, so (c) doesn't matter (yet). Working up some KNI BLAS routines is on my agenda, though. -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
