I don't see that as much of a problem. The mess arises from some simple
lacks in the objects in kernel and the methods required to co-ordinate.
Lots of drivers are written by a lot of people in the kernel and they
work just fine. The ext3 authors don't spend their lives co-ordinating
with SCSI driver authors, they just get the API right.




Sorry, but I think that's (Possibly?) a really really bad & misleading example... Apples & Apples vs Chocolate & Milkshakes... The dual screen problem with DRM & fb is two drivers accessing (Sometimes) the same hardware. The ext3 vs SCSI is a filesystem, that sits on-top of a disk device that may just be SCSI.. Or IDE..

The fs -> SCSI interface is a logical one.

Unless you can have fb sitting on top of DRM of course... (I discount DRM on-top of fb, because of the D == Direct... No other reason :)...

Does it make sens to have fb ontop of DRM at all? Anyone?
