Author: avg Date: Sun Apr 8 19:58:38 2012 New Revision: 234040 URL: http://svn.freebsd.org/changeset/base/234040 Log: intpm: reflect the fact that SB800 and later AMD chipsets are not supported They do not have compatible configuration registers in PCI configuration space. Instead their configuration resides in AMD "PM I/O" space (accessed via a pair of I/O space registers).
