This series removes the Sun Cassini, LDOM vswitch and sunvnet drivers. In a recent patch series that touched these drivers [1], it was suggested that these drivers should be removed completely. git logs suggest that there hasn't been any significant feature addition, improvement or fixes to user-visible bugs in a while. A web search didn't indicate any recent discussions or any evidence that there are users out there who care about these drivers. The idea behind putting out this series is to either establish that these drivers are used and should be maintained, or remove them.Anirudh, The Sun LDOM vswitch and sunvnet drivers are still in use, please do not remove them or the event tracing. We use them internally and you don't see any discussions because they generally work fine (AFAIK).Hello Karl, Thanks for chiming in. Are there recent platforms where these drivers are used? If yes, do you know which ones? Or are these drivers useful in old/legacy platforms that are still around but perhaps no longer in production?
These drivers work on older T4, T5, etc to the latest T7, T8 Sun servers (e.g. T8-2, T8-4, note, T7/T8 are still in production). They may also work on T2/T3 (but I don't use those anymore, though Adrian (John Paul Adrian Glaubitz [off-list ref]) might). You might have missed a lot of the linux SPARC developers since they are on the debian-sparc@lists.debian.org list, hence I'd ask there also.

I think you are also going to break things by removing Sun Cassini support, but I am not using it personally.You suspect there are users for this driver as well?
Yes, they may not have seen this yet or recognized the servers this card goes in (post on debian-sparc@lists.debian.org list).

What user visible bugs are you referring to here?I was saying I don't see any evidence of recent bug fixes, which would make sense if these drivers "just work".
ok, no worries. Cheers Karl
