No, we don't change NCPU at a platform level on sun4v. We're trying to stay away from platform specific changes like that. One of the things I want to change in sun4v, however, is all these arrays whose size is NCPU. It wastes memory and possibly in some cases processing time on the older sun4v systems like T1000/T2000 (32 "cpus" max) or even T5120/T5220 (64 "cpus" max). See CR 6685223 for one of these issues. -- Dave Marquardt Sun Microsystems, Inc.
