It's similar, but there is still a bunch of DCE specific code. No one has written that DC code for DCE 6 yet. One could use the DC DCE8 code as a guide, but it still has to be done.
I have not checked the new code, but does it mean the atombios is gone for DCE programming?
It's still there. Even with atombios, there is still a bunch of DCE specific programming required (page flips, interrupts, hotplug, watermarks, LUTs, cursors, etc.). DC also adds support for a bunch of new features that are were not supported by either atombios or the old modesetting code (regamma/CTM, DP/HDMI audio, dchub programming for display buffers in system memory for APUs, etc.).
As far as I can remember, not for the new features ofc, DCE programming for GCN1 is very similar if not mostly the same than DCE programming for GCN1.1/2 which is supported by the new DC code.
Is this planned?
Right, as I said, you could definitely leverage the support for DCE8 in DC. The blocks are very similar. At the moment, we have no plans to implement DC support for DCE6.
