On Wed, Feb 12, 2014 at 02:23:48PM -0500 I heard the voice of John Baldwin, and lo! it spake thus: > > Assuming you do have 10h CPUs, it would be nice to see what cpuid > flags are set for your processors. If it's any help, CPU: AMD Phenom(tm) II X4 980 Processor (3712.47-MHz K8-class CPU) Origin="AuthenticAMD" Id=0x100f43 Family=0x10 Model=0x4 Stepping=3 Features=0x178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT> Features2=0x802009<SSE3,MON,CX16,POPCNT> AMD Features=0xee500800<SYSCALL,NX,MMX+,FFXSR,Page1GB,RDTSCP,LM,3DNow!+,3DNow!> AMD Features2=0x837ff<LAHF,CMP,SVM,ExtAPIC,CR8,ABM,SSE4A,MAS,Prefetch,OSVW,IBS,SKINIT,WDT,NodeId> Though I'd naively think it would make more sense to check the Family directly rather than guessing from flags. But my assumption that's practical could be total hogwash... -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
