Functions
-
static void scheduler_timeout_callback(struct TimerListItem *it)
-
static int update_timer_list(GlobalContext *global)
-
Context *scheduler_wait(Context *ctx)
move a process to waiting queue and wait a ready one
move current process to the waiting queue, and schedule the next one or sleep until an event is received.
- Parameters:
c – the process context.
-
static Context *scheduler_run0(GlobalContext *global)
-
Context *scheduler_run(GlobalContext *global)
run the scheduler and return a process to be executed.
- Parameters:
global – the global context.
-
Context *scheduler_next(GlobalContext *global, Context *c)
gets next runnable process from the ready queue.
gets next runnable process from the ready queue, it may return current process if there isn’t any other runnable process.
- Parameters:
global – the global context.
c – the current process.
