Bananymous 55bb0084aa Kernel: namespace and function renames
MMU moved to namespace kernel
Kernel::Memory::Heap moved to just Kernel

Bananymous dc0f8b383f Kernel: Usespace threads now have an interrupt stack 2023-04-25 14:49:18 +03:00
Bananymous 48445f12ac Kernel: More proper paging in Elf loading 2023-04-22 18:17:44 +03:00
Bananymous 7530482cc2 Kernel: Cleanup process creation for userspace 2023-04-22 16:51:50 +03:00
Bananymous d63716db96 Kernel: Process is not reference counted any more
This was not necessary and it made things needlessly complicated

Bananymous fdb4eb6042 Kernel: Move kmalloc and MMU to Memory directory 2023-04-18 10:18:15 +03:00
Bananymous 8ee63f8264 Kernel: We can create basic userspace processes
These are still allocated on the kernel memory

Bananymous 3201c3654e Kernel: Threads now use only 4 KiB stack :) 2023-04-12 00:22:08 +03:00
Bananymous dcee92a6bc Kernel: Thread is no longer RefCounted
This makes developement with Scheduler much easier against compiler
optimizations. I could now remove the pragma GCC optimize stuff.

Bananymous 1b7625581d Kernel: Add basic concept of Processes
We now create Shell as a process that has its own threads
2023-03-16 12:17:04 +02:00
Bananymous af854ec9e1 Kernel: Thread creation now takes void(*)() as entry and void* as data
This simplifies threading for the future and gets rid of (undefined?)
cast of member function pointer to address

Bananymous d90aba0963 Kernel: Create CriticalScope and fix kmalloc
This disables interrupts for the current scope and restores them
after the scope. This is used in kmalloc, since scheduler might
call into kmalloc/kfree, but deadlock if some thread is currently
trying to allocate. This allows us to use kmalloc in Scheduler.

Bananymous 23b3028e15 Kernel: Rename RefCounted -> RefPtr and implement RefCounted 2023-03-08 03:26:25 +02:00
Bananymous b8ee77eb78 Kernel: Initial work on new scheduler with queues
Sleeping is definately broken

Bananymous 1dd61e93b6 Kernel: Threads cannot take arguments anymore 2023-03-02 01:56:09 +02:00
Bananymous 1bd8b0fe5c Kernel: Sleep now actually sleeps and allows idling 2023-02-19 18:52:25 +02:00
Bananymous 5b5e620d8a Kernel: Improve multithreading support
We can now use arbitary BAN::function<void(...)> as the Thread.
I also implemented multithreading for i386 since it was not done
on the initial multithreading commit.

Bananymous 6a9d60a8fb Kernel: Implement somewhat functioning multithread support
This still uses only a single cpu, but we can now have 'parallelization'

This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.

I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D
