Great.

It is the common api for all accelerator drivers that you must use if
you wish to have a Linux driver for this type of hardware.  There should
be documentation in the kernel subsystem to read, and of course, there
are existing drivers using the api already.  If you have specific
questions about the api, please ask on that mailing list.
