Unfortunately the IOMMU page fault is happened. So we need some codes for
protecting kernel.
Thank you~

Btw, what is the hw response to invalid input (ie. bottom>top, invalid
size, etc)?
Ie. if it will just ignore the blit or raise an error irq which can be
handled sanely, it could be ok to avoid the overhead of the cmdstream
checking in the kernel. The kernel part really just needs to ensure
that
