Help text

This option enables or disables the use of domain switching using the DACR (domain access control register) to protect memory domains from each other. In Linux we use three domains: kernel, user and IO. The domains are used to protect userspace from kernelspace and to handle IO-space as a special type of memory by assigning manager or client roles to running code (such as a process).
