Statics

CURRENT_THREAD	An Arc to the currently running thread.
SCHEDULE_QUEUE	The schedule queue

Functions

add_to_schedule_queue	Adds a thread at the end of the schedule queue, and changes its state to 'scheduled' Thread must be ready to be scheduled.
create_first_process⚠	Creates the very first process at boot. The created process has 1 thread, which is marked as the current thread, and added to the schedule queue.
find_next_thread_to_run	Parses the queue to find the first unlocked process. Returns the index of found process
get_current_process	Gets the ProcessStruct of the current thread, incrementing its refcount.
get_current_thread	Gets the current ThreadStruct, incrementing its refcount.
internal_schedule	Internal impl of the process switch, used by schedule and unschedule.
is_in_schedule_queue	Checks if a thread is already either in the schedule queue or currently running.
schedule	Performs a process switch.
scheduler_first_schedule⚠	The function called when a thread was scheduled for the first time, right after the arch-specific process switch was performed.
set_current_thread⚠	Sets the current ThreadStruct.
try_get_current_process	Gets the ProcessStruct of the current thread, incrementing its refcount. Will return None if we're in an early boot state, and it has not yet been initialized.
try_get_current_thread	Gets the current ThreadStruct, incrementing its refcount. Will return None if we're in an early boot state, and it has not yet been initialized.
unschedule	Removes the current thread from the schedule queue, and schedule.
