Virtual Memory Manager (vm)

The virtual memory manager, called vm, is responsible for allocating physical memory pages and managing tasks (as a pager task), etc.

Once the kernel initializes itself, it loads and starts vm as the first task.


  • Allocating and mapping physical memory pages. In other words, the kernel does not allocate memory pages at all. The responsibility is delegated to vm.
  • Launching tasks and handling their exceptions (e.g. page faults) as their pager task.
  • Service discovery (ipc_lookup API).
  • Out-of-Line payload transmitting.
