CCed Mark, who is our CPU PM expert. Below is Mark's answer to your question, what CPU will be supported by CPUFreq.
"We define which CPUs we support by family and model. AMD Family >= 0x10. Intel Family 0xF - Models >=0x3 or Family 0x6 - Models >= E The list in your mail is correct except for the uni-processor Opteron. That would be the frkit support, not Solaris support." - Simon James Cornell wrote: > "10th or above" doesn't really help me, but I suspect it means > Barcelona or above (4 core) as TSC support is missing in all prior and > Sun doesn't want to put engineering efforts into "retrofitting" it on > prior.
