Debug log writing performance is extremely important when you are using
the log for debugging work rather than for panic display. I don't think
that is a show stopper because having a logger makes sense and someone
can write a better render engine if they care.

Supporting any target is also going to be useful but you do need to
support non linear framebuffers. A GMA500 with something like an X
display in use for example does not have a linear mapping of the
framebuffer memory. I don't believe its exactly unique in this.

What I am more dubious about is tying it to DRM. Yes it uses DRM
constants but it doesn't appear functionally to have a single tie to
either DRM or even framebuffer.

It's potentially useful in cases where neither framebuffer or DRM are
compiled into the system.
