I'm building a new server with 7.0 BETA4 (it will track stable) with
the following CPU
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ (2600.02-MHz K8-
class CPU)
Origin = "AuthenticAMD" Id = 0x60fb1 Stepping = 1
Features
=
0x178bfbff

,PSE
,TSC
,MSR
,PAE
,MCE
,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT>
Features2=0x2001<SSE3,CX16>
AMD Features=0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow!+,
3DNow!>
AMD Features2=0x11f<LAHF,CMP,SVM,ExtAPIC,CR8,Prefetch>
Cores per package: 2
What optimizations should I make in make.conf?
The example make.conf says
AMD64 architecture: opteron, athlon64, nocona, prescott, core2
But I don't know whether althon64 or core2 would be the safest and
most appropriate.
Also GENERIC for amd64 lists
cpu HAMMER
is that the best (only) choice? And if not, where can I find a list
of alternatives? I didn't find anything in the NOTES files telling me
what was available.
