What is the driver environment you are running in? I assume IOKit.
Are both drivers yours? Do you have a provider/client connection?
Can you include headers between the two kexts? Do they live in the
same binary? What is the memory going to be used for?
The message/messageClient code is mainly used to call a subroutine in
client driver from a provider.
Finally within the kernel every thing lives in the same address space
so you don't have to copy data you can just pass pointers.

What is the most efficient way of moving data between two kexts?
Are the IOService message/messageClient calls the recommended way to
do this? Do they involve memcpy?
