If the amount of data required is large you could try setting up a
block of pageable memory inside the kernel. I believe the
IOBufferMemoryDescriptor has a pageable option. This may be a good
solution for your problem.
Also note that the kernel virtual address space is limited (3 GB on
10.3 and later, 1 GB on earlier systems). So, it's not a good idea
to allocate too much memory in the kernel, even if it is pageable.
