Hopefully soon (in five years? =) we can say that omapdrm supports all

I'd love to send a patch to remove omapfb, but I'll let you do the
honours :-)
Not before we add DSI support to omapdrm...
Hmm do your mean RFBI? The DSI support we already have :)
Oh, I didn't even remember RFBI... But it is not supported in omapfb either, so it's not blocking
removal of omapfb.
We are still missing DSI command mode support, and moving it to the common DRM model.
This is probably known, but for devices that would like use PowerVR SGX,
there sometimes is only userspace available that works with omap(l)fb,
and not with DRM. The Nokia N900 is such an example.
There might be a newer release of (closed) userspace coming for the
aging device(s), but as it stands, I don't think it's possible to do 3D
with PowerVR SGX on omapdrm currently.
But I might be wrong...
Yes SGX is a bottleneck currently for omap3 users. And I think
RFBI is blocking n8x0 from moving to omapdrm and finally leaving
drivers/video/fbdev/omap2 behind.
With those blockers fixed, I'd also be happy to just get rid of
drivers/video/fbdev/omap2 as there should be no reason to
keep using it.
I don't know what to do about SGX, but if someone sends patches to omapdrm to allow using SGX, I'll
review =).
