Author: marius Date: Thu Mar 19 15:32:16 2009 New Revision: 190067 URL: http://svn.freebsd.org/changeset/base/190067 Log: MFC: r185007 Use the spitfire VIS block copy/zero functions also with cheetah- class CPUs. In theory one could also use versions additionally taking advantage of the prefetch cache with cheetah-class CPUs, in my worldstone runs these either didn't provide extra speedup (USIII+) in comparison to the existing spitfire versions or were even slightly slower (USIIIi) though, so they aren't committed for now. The basic problem leading to the VIS-based copy/zero functions being initially disabled for cheetah-class CPUs was solved by letting cheetah_init() clear DCR_IFPOE.
