Field Documentation

thread_t* nil_system::current

Pointer to the running thread.

Definition at line 658 of file ch.h.

Referenced by chEvtWaitAnyTimeout(), chSchDoReschedule(), chSchGoSleepTimeoutS(), chSchReadyI(), chSemWaitTimeoutS(), chSysInit(), chThdEnqueueTimeoutS(), and chThdSuspendTimeoutS().

thread_t* nil_system::next

Pointer to the next thread to be executed.

Note

This pointer must point at the same thread pointed by current or to an higher priority thread if a switch is required.

Referenced by chSchDoReschedule(), chSchGoSleepTimeoutS(), chSchReadyI(), and chSysInit().

volatile systime_t nil_system::systime

System time.

Definition at line 669 of file ch.h.

Referenced by chSysTimerHandlerI().

systime_t nil_system::lasttime

System time of the last tick event.

Definition at line 675 of file ch.h.

Referenced by chSchGoSleepTimeoutS(), and chSysTimerHandlerI().

systime_t nil_system::nexttime

Time of the next scheduled tick event.

Definition at line 679 of file ch.h.

Referenced by chSchGoSleepTimeoutS(), and chSysTimerHandlerI().

cnt_t nil_system::isr_cnt

ISR nesting level.

Definition at line 685 of file ch.h.

Referenced by _dbg_check_disable(), _dbg_check_enable(), _dbg_check_enter_isr(), _dbg_check_leave_isr(), _dbg_check_lock(), _dbg_check_lock_from_isr(), _dbg_check_suspend(), _dbg_check_unlock(), _dbg_check_unlock_from_isr(), chDbgCheckClassI(), chDbgCheckClassS(), and chSysInit().

cnt_t nil_system::lock_cnt

Lock nesting level.

Definition at line 689 of file ch.h.

Referenced by _dbg_check_disable(), _dbg_check_enable(), _dbg_check_enter_isr(), _dbg_check_leave_isr(), _dbg_check_lock(), _dbg_check_lock_from_isr(), _dbg_check_suspend(), _dbg_check_unlock(), _dbg_check_unlock_from_isr(), chDbgCheckClassI(), chDbgCheckClassS(), and chSysInit().

const char* volatile nil_system::dbg_panic_msg

Panic message.

Note

This field is only present if some debug options have been activated.

Accesses to this pointer must never be optimized out so the field itself is declared volatile.

Referenced by chSysHalt().

thread_t nil_system::threads[CH_CFG_NUM_THREADS+1]

Thread structures for all the defined threads.

Definition at line 704 of file ch.h.
