I understand that sometimes with early hw enabling a lot of development
needs to happen behind closed doors because not yet approved for
publishing. SI isn't such a case, still some of these patches are at v6/7
already when they show. Also, you're not the author of any of these. And
they all have r-b tags already.

Everyone else here in the drm subsystem seems to have no problem at all
with developing in the open, why can't AMD?
