Hi,
It happens on several machines and this only seem to happen if there
was a wrap around in the log buffer (it's a first observation on a
limited number of sample so it might be a coincidence)
I think the culprit is print_time and has nothing to do with wrap
around, just the uptime.

sg_virt() on highmem pages won't work. This WARN_ON() should catch some
that still try.

What I propose is to move the client registration code that is currently

not end up in drivers/gpu/host1x.
Ok.

The problem that this solves is that the DRM driver needs to be bound to
a specific platform device. None of the DRM subdevices are suitable
because they are only part of the whole DRM device. I think that host1x
