make.conf CPUTYPE Xeon Conroe?
I'm running FreeBSD 7.0 on a server with an Intel Xeon Dual-Core 3060 Conroe (2.4GHz) CPU. I'm wondering what I should set CPUTYPE to in my /etc/make.conf. The file /usr/share/examples/etc/make.conf has this information: # (Intel CPUs)core2 core nocona pentium4m pentium4 prescott # pentium3m pentium3 pentium-m pentium2 # pentiumpro pentium-mmx pentium i486 i386 I guess those are the possibilities. Which one should I choose for my processor? Also, by accident, I had CPUTYPE=p4 in my make.conf when I compiled world, kernel, and ports. p4 is a flag from older FreeBSD distributions I think. Will this (this meaning both that p4 may be unrecognized and/or it's not my processor type) cause any problems, or should I recompile everything with the correct CPUTYPE flag? Installing world is a hassle because it's not easy for me to do it from single user mode.

If you're heart is set on it though, your CPU is a core2. -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB signature.asc Description: This is a digitally signed message part.

I ask because I've had CPUTYPE? = p4 on this machine for five years - dozens of buildworlds and possibly thousands of port builds - and never had anything attributable to that go wrong.

Re: make.conf CPUTYPE Xeon Conroe?
Alike other users how can you compare the benefits pros/cons of setting the CPU type? Documentation reads otherwise and it only mentions possible cons in one section? # CFLAGS controls the compiler settings used when compiling C code. # Note that optimization settings other than -O and -O2 are not recommended # or supported for compiling the world or the kernel - please revert any # nonstandard optimization settings to -O or -O2 -fno-strict-aliasing # before submitting bug reports without patches to the developers.
