Drew Galbraith 46ae5de30a [Zion] Free paging structures after process exit. 2023-11-24 17:19:32 -08:00
Drew Galbraith 2dd69f5844 [Zion] Map user stacks in as regular MemoryObjects.
This allows us to easily track the physical memory so it
can be freed when the thread exits. It also simplifies the page fault
handler as it just needs to check regular mappings to find a user stack.

Drew Galbraith a47bac9966 [zion] Dynamically check Capability type.
Instead of passing an enum with the capability when creating it, relying
on polymorphism and a template struct tag to determine the object type
at runtime.

This is cleaner and avoids errors where we pass the wrong capability
type with the cap and do a bad cast at runtime.

Drew Galbraith 23895b5c6c Spawn Processes using memory primitives rather than and elf loader.
This allows us to remove the temporary syscall for that style of process
spawn.
