Just to clarify a bit - my point was not to suggest that port is irrelevant, or that the FreeBSD should not go there. In fact I believe on contrary from what I know sun4v is good as a testbed for the future of multi-processor architectures today - definitely we will see ever increasing number of cores in commodity Intel/AMD servers in few years from now. So that in that sense sun4v work is very important if the FreeBSD project wants to keep ahead of things, not catching-up later. However, realistically immaturity of the port as well as scarcity of hardware limits number of users severely. Therefore, absence of PRs should not be surprising to anyone. -Maxim
