So our Android folks seem to routinely run out of ioctl numbers in
their product/downstream branches. But ime after some decent review of
the new interfaces and not just blindly creating interfaces because
that's easier we have rather slow ioctl number consumption in i915. So
presuming you do decent review and dont fork your driver for every
generation (which seems to be how every blob gfx driver team works) I
don't think you have a problem. Of course that's a massive change in
approach and in my experience with intel-internal discussion will
require a lot of training.
