Casper, So, I was thinking this morning about the powernow driver issue for AMD X2 machines. According to Tom de Waal, families 15 and older use C-states and families 16 and newer use P-states. It is my understanding that the newer powernow driver uses this P-state information to handle the frequency scaling of the cpu, thereby throttling it down during periods of low activity.
This being the case, is it correct to assume that the older powernow driver (the one for the single core cpus) uses C-state information to throttle the cpu down? Also, if it works for the older single core cpus (however it works), is it possible to make it work for older dual core cpus? If so, how? Michael. -- This message posted from opensolaris.org
