X is doing a mmap of /dev/mem instead of /dev/fb ?

You can normally map the fb mapping /dev/fb and then map the

using /dev/fb at an offset beyond the framebuffer (fix->smem_len).

If X is using /dev/mem instead, then it's being stupid and needs to

fixed...

It's up to the driver, and again, the current radeon driver doesn't
use
radeonfb at all anymore...

Right. And I'm happy to go fix what remains, don't get me wrong here :-)
We all know how stupid legacy code can be !

I'll try to get some patches to expose a new version of the structure
sometimes in the upcoming week or two (we'll see what time permits) and
then see about fixing X drivers that need fixing, though hopefully with
pci-rework being upstream now, that shouldn't be many.

The main issue is directfb. I hope they'll catch up with the new ioctls.

Ben.
