Detailed Description
Each device may have one or more disjoint regions of address space. This can be in I/O space or memory space.
Constructor & Destructor Documentation
| Device::Address::Address | ( | const String & | n, |
| uintptr_t | a, | ||
| size_t | s, | ||
| bool | io, | ||
| size_t | pad = 1 |
||
| ) |
Constructor, takes arguments and assigns them blindly to member variables, then creates the IoPort or MemoryMappedIO instance.
