Not obvious why this is needed. According to Deniel Vetter this is most likely a historic artefact dating back to the days where drm drivers exposed hardware registers as mmap'able gem objects, to avoid dumping touching those registers.
Clearly a NAK.
We still have that and really don't want to try dumping any CPU inaccessible VRAM content even if it is mapped into the address space somewhere.
Thanks for the clarification, I'll drop the patch.
cheers, Gerd
