Functions

static void scheduler_timeout_callback(struct TimerListItem *it)

static void scheduler_make_ready(Context *ctx)

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 void scheduler_process_native_signal_messages(Context *ctx)

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.

Returns:

runnable process.

void scheduler_init_ready(Context *c)

Init a process in the ready state, moving it to the scheduler queue.

Parameters:

• c – the process context.

void scheduler_signal_message(Context *c)

Signal a process that a message was inserted in the mailbox.

Parameters:

• c – the process context.

void scheduler_terminate(Context *ctx)

removes a process and terminates it from the scheduling queue

removes a process from the scheduling ready queue and destroys it if its not a leader process.

Parameters:

• c – the process that is going to be terminated.

void scheduler_stop_all(GlobalContext *global)

Terminate all schedulers. Every process is terminated gracefully at next scheduling point.

Parameters:

• global – the global context.

void scheduler_set_timeout(Context *ctx, avm_int64_t timeout)

sets context timeout

set context timeout timestamp, move context to wait queue and update global next timeout timestamp.

Parameters:

• ctx – the context that will be put on sleep

• timeout – amount of time to be waited in milliseconds.

void scheduler_cancel_timeout(Context *ctx)
