Does QNX support virtual memory?
Yes. Don’t confuse this with a swap file though. Virtual memory only refers to the mapping of real physical memory through a MMU. QNX operates in the protected mode of the Intel processors, and makes use of LDT and GDT selectors to provide memory mapping to physical memory. Use of virtual memory also allows QNX to provide shared memory on a per-process basis as well as memory protection between processes, and even the processes that make up the OS itself.
