X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 27 Jan 2007 01:34:41 -0000 ...or when will FreeBSD support Pentium features? I want to apologize in advance if this should be on the kern@ But it seemed apropriate for this list too and I'm already on it. I've noticed building kernels, that since v. >= 5 that during the phase 2/3 all the lines echoed to the screen contain: -mno-mmx -mno-3dnow -mno-sse -mno-sse2 ... As Pentium have been the "norm" for many years now, why aren't these /assumed/? I'm building on several SMP PIII's and a build is in process now on a PIV Athalon running 6.2 the source and ports tree were cvsupped 01-25 @02:03:00 -0800. Yet this current kernel build is echoing these same -mno- lines. I have machine i386 cpu I686_CPU device apic uncommented and I386_CPU, I486_CPU & I586_CPU commented. I have grepped the /src/sys/conf/NOTES as well as the /src/sys/i386/conf/NOTES Yet the only case I find relating to this is on line: 130 in: /src/sys/i386/conf/NOTES which reads: # CPU_ENABLE_SSE enables SSE/MMX2 instructions support. This is default # on I686_CPU and above. Default? hmmm... not as far as I can tell. Anyway, I would *greatly* appreciate any insight on this issue. Do I need to pollute my make.conf file to achive a Pentium kernel? Thank you very much for all your time and consideration. --Chris -- panic: kernel trap (ignored) ----------------------------------------------------------------- FreeBSD 5.4-RELEASE-p12 (SMP - 900x2) Tue Mar 7 19:37:23 PST 2006 /////////////////////////////////////////////////////////////////
