Current Status

The sun4v (UltraSPARC-T1) code was removed from -HEAD in May 2011. The reason was due to lack of stability somewhere in the VM system, combined with lack of interest from other developers once the initial developer ceased working on it. Because of the latter, the codebase was not keeping up with changes in -HEAD, leading to bitrot.

If someone wishes to pick up sun4v, there are still machines available for them to access [contact MarkLinimon], and the code is still in the repository.
