[ Please keep me in the Cc; I'm not subscribed to -questions. ] I've recently acquired a new laptop with a Crusoe TM5800 CPU in it. I'm trying to determine the optimal kernel configuration for this machine and the docs appear to be lacking in this area. I initially built a kernel with all _CPU options but I686_CPU diked out. The kernel failed to boot so I went back to GENERIC and found out that it actually shows up in dmesg as an I586 class CPU. I've now got a kernel built which has all of the default _CPU options back in it and that's running fine. I also built a new world for the thing earlier today and both the current world and kernel running on it were built with CPUTYPE=i686 in /etc/make.conf. If I am to interpret the dmesg correctly then this CPU should not support the i686 instruction set but it doesn't seem to be suffering from any i686 specific optimizations. In fact, I just built the XFree86-4 port plus all dependencies using the -march=pentiumpro'd kernel and userland and it worked just fine. Does anyone know definitively whether this thing supports the i686 instruction set and if so why dmesg reports it as an i586 class CPU? dmesg snippet: CPU: Transmeta(tm) Crusoe(tm) Processor TM5800 (730.44MHz 586-class CPU) OS version: [bandix@taran ~]% uname -a FreeBSD taran 4.6-RELEASE-p2 FreeBSD 4.6-RELEASE-p2 #1: Wed Jul 17 16:07:22 CDT 2002 root@taran:/usr/obj/usr/src/sys/TARAN i386 Thanks, Brandon D.
