Fix TSS
Also change to .{} syntax where appropriate.
Added the SS segment
Fixed spelling
Refactoring GDT
Multitasking working for now
WIP scheduler
Refactored Bitmap a bit
WIP still
Task switching working
Handlers return the stack pointer that will be used to restore the tasks stack, normal handlers will return the same stack pointer it was called with where task switching will return the stack pointer of the next task and restore its state using the interrupt stub.
Initial scheduler done
Created a stage 2 init task
Change u32 to usize
Move Task to arch specific
WIP
WIP2
Removed esp from task, replaced with stack_pointer
Removed the debug logs
Fixed init task stack
Change pickNextTask to pointer manipulation
This allows less allocations so faster switching
Temporary enable interrupts for some runtime tests
PIT and RTC need interrupts enabled to run their runtime tests
Renamed schedule => pickNextTask, comptime bitmap for pids not task init
And some other stuff: No pub for the task anymore
Use the leak detector allocator
Fmt
Fix unit tests
And some other stuff :P
PR review
Moved Task out of arch and have the stack init in the arch file
Mocking clean up
Removed commented code
Renamed createTask to scheduleTask where the user will have to provide a task to schedule
Removed redundant pub in log runtime test
Removed global allocator for scheduler
Cleaner assembly in paging
Fmt
Added new Scheduler test mode
Added new test mode to CI
Removed one of the prints
Added doc comment, task test for i386
Removed test
WIP
Runtime tests work
Have a global set in one task and reacted to in another. Also test that local variables are preserved after a task switch.
Removed new lines
Increased line length
Move the allocation of the bool above the task creation
