Drew Galbraith 6986f534f8 Add a method for blocking threads on ports. 
Additionally add the first lock class since we are becoming more
concurrent.
 2023-06-12 20:56:25 -07:00
Drew Galbraith 81b925eea0 Add a basic IPC setup with Channel Object. 
Pass a process a channel endpoint on startup that it will use to
get it's initial capabilities.

Drew Galbraith 55340e2917 Make Capability RefCounted 2023-06-07 06:21:36 -07:00
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.
 2023-06-07 00:04:53 -07:00
Drew Galbraith 4e278a4664 Make a KernelObject base class for all Capabilities. 2023-06-06 20:13:07 -07:00
Drew Galbraith 2e1357255c Create a RefCounted type and use it for Thread. 
This should prevent me from actually creating 2 shared ptrs of
a single kernel object with their separate ref counts.
 2023-06-06 19:05:03 -07:00
Drew Galbraith c6921b5459 Add validity check in shared ptr 2023-05-30 01:05:50 -07:00
Drew Galbraith 3fee5ac9d7 Rework scheduler to store the current thread separately. 
This works better with the sleep thread and lets us check state
transitions more easily.
 2023-05-29 22:54:22 -07:00
Drew Galbraith 80d2bf1aaa Move Processes and Threads to be stored in SharedPtr 
Reference counting lets us pass these around a bit more easily.

SharedPtr was lightly tested using uint64_t in the main zion funcion.

Also add a sleep functionality instead of panicking. Functionally the
same right now since we don't preempt.
 2023-05-29 15:50:38 -07:00
Drew Galbraith 9f3ffbf5b4 Move Process to storing Threads in a linked list. 
This should really be a vector or hashmap of some sort but this is fine
for now.
 2023-05-29 15:08:02 -07:00
Drew Galbraith 5cab9f843e Move process list to a linked list. 
Add basic iteration ability to the linked list.
 2023-05-29 14:59:23 -07:00
Drew Galbraith 71196dc90f Move scheduler threads to a linked list implementation. 
Removes the internal next ptr from the Thread class.

We avoid doing a memory operation when scheduling on yield because we
simply cycle the item to the back of the list.
