>Description:
Running on a PC Engines APU 1C board with the following CPU:
CPU: AMD G-T40E Processor (1000.02-MHz K8-class CPU)
Origin = "AuthenticAMD" Id = 0x500f20 Family = 0x14 Model = 0x2 Stepping = 0
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=0x802209<SSE3,MON,SSSE3,CX16,POPCNT>
AMD Features=0x2e500800<SYSCALL,NX,MMX+,FFXSR,Page1GB,RDTSCP,LM>
AMD Features2=0x35ff<LAHF,CMP,SVM,ExtAPIC,CR8,ABM,SSE4A,MAS,Prefetch,IBS,SKINIT,WDT>
TSC: P-state invariant, performance statistics
The kernel doesn't attach the powernow driver, but according to x86info the CPU would be capable of using it:
