Calling svcBreak on retail will only terminate the process which called this SVC. Only ControlMemory and MapMemoryBlock can be used to map memory pages, these SVCs only support mapping execute-never R/W pages.
DebugActiveProcess is used to attach to a process for debugging. This SVC can only be used when the target process' ARM11 descriptors stored in the exheader have the kernel flag for "Enable debug" set. Otherwise when that flag is clear, the kernel flags for the process using this SVC must have the "Force debug" flag set.
