NetBSD and SpeedStep on the Atom N450
My Dell Inspiron Mini 10 ships with an Intel Atom N450. Right now, TuM’Fatig is running on an USB disk plugged in the XPS M1330. So the Mini is in testing mode. Today was the day when I checked the status of NetBSD’s SpeedStep implementation on N450. Sadly, NetBSD 5.1_STABLE still does not support it ; NetBSD 5.99.55 knows about it though.
SpeedStep on NetBSD/xen
When you boot NetBSD/xen, you don’t get SpeedStep anymore. At least, on NetBSD 5.1, as of 2011-07-14. Some job have been done in 2009 but wasn’t kept in the sources. Check Add Intel SpeedStep and AMD PowerNow! support in Xen dom0 for more informations.
