Using a quad-core - Desktop - I need it - Normally the cores runs at 45C - under freebsd it more like 51-55C and its giving me heat burns on my feet ;= =2D) All the Core Micro architecture uses TM2 approach and ODCM as secondary. The Xeon's systems seems as a rule to have reasonable APCI implementations= =20 =2D however quite a lot of Desktop systems does not really and depends upon= OSPM to give the information - Judging from the Linux implementation that is the= approach they have taken - eg. cstate.c etc -=20 A quad core system are in idle wait quite a lot due to the way that portupg= rade etc. works but I don't think that the system enters "C1 Auto Halt Stop Grant" which in= it self would half the power used.=20 =46rom a linux presentation it looks like the Power Usage swings between 31= Watt - down to 1.8Watt in DC4 state so there a lot of heat and power to be saved ;-) So I think there are good reasons to look at TM2 and Mwait etc=20 >=20 > -- > Rui Paulo > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" >=20
