current_tick = rt_tick_get(); 在软件定时器检测和硬件定时器检测中的调用顺序不同;按我理解没有差别,放入前面运行更为合适

    while (!rt_list_isempty(&timer_list[RT_TIMER_SKIP_LIST_LEVEL - 1]))
    {
        t = rt_list_entry(timer_list[RT_TIMER_SKIP_LIST_LEVEL - 1].next,
                          struct rt_timer, row[RT_TIMER_SKIP_LIST_LEVEL - 1]);

        /* re-get tick */
        current_tick = rt_tick_get();

• 在硬件定时器检测中的该段代码,我认为可以放入外部判断既可;但是没有实际环境测试;这个地方需要检测一下是否合理

#ifdef RT_USING_SMP
    /* Running on core 0 only */
    if (rt_hw_cpu_id() != 0)
    {
        rt_spin_unlock_irqrestore(&_htimer_lock, level);
        return;
    }
#endif
