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.
Features
- 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_lookupAPI). - Out-of-Line payload transmitting.
