This is correct, the GPU has an MMU. The reason I introduced this custom
CMA DTB entry is to allow creation of a standalone DMA heap whic

re required to construct a protected mode job in user space,
which can be submitted to the GPU.
Some of the changes may seems controversial and we would appreciate getting
opinion from the community.

- When a protected mode job is suspended as a result of
the CSGs rotation, the GPU will send an IRQ to the CPU
to notify that the protected mode job needs to resume.
This sequence will continue so long the user space is
submitting protected mode jobs.
