To provide user-space a set of interfaces to: 1. pass in a ccw program to perform an I/O operation. 2. read back I/O results of the completed I/O operations. We introduce an MMIO region for the vfio-ccw device here. This region is defined to content: 1. areas to store arguments that an ssch required. 2. areas to store the I/O results. Using pwrite/pread to the device on this region, a user-space program could write/read data to/from the vfio-ccw device.
