Thanks for the explanation. Yes sun4v and sun4u are different architecturally. I remember the additional testing we had to do in the Sustaining team when sun4v was originally introduced and the extent of debates we had with respect to the assumptions that were made in the original T-series processors. Some of the assumptions were proved too conservative and had to be changed in the later designs of the T-series procs. Very interesting stuff by itself. But I guess the question was from a general Sparc support point of view. T2+ is more interesting to most people I think.
