然后我想着不是还有一个定时器没有开启吗,我就在void secondary_cpu_c_start(void)
{
int timer_irq_number;

timer_irq_number = 92;

rt_hw_vector_init();

rt_hw_spin_lock(&_cpus_lock);

arm_gic_cpu_init(0, platform_get_gic_cpu_base());

// arm_gic_set_cpu(0, timer_irq_number, 0x2); // timer1

// timer1_init();
//rt_hw_interrupt_install(timer_irq_number, rt_hw_timer1_isr, RT_NULL, "tick1");
//rt_hw_interrupt_umask(timer_irq_number);

rt_system_scheduler_start();

}
这里把定时器2也开启了,现在发现之前开启的那个定时器1中断不进去了,进去的都是定时器2的中断,gui的任务夜跑不起来了,也就是说我在second cpu里面在开启一个定时器就不正常了,找了资料说smp需要开启2个定时器,为什么我这里开启2个定时器之后,前面那个定时器中断进不去了呢,然后我把second cpu的定时器关闭,性能上也达到了双核的提升了呀,因为我如果禁止smp,那么性能比较差的明显的,我现在迷糊了,定时器到底要不要开启2个,能否讲解一下这方面的疑惑,非常感谢

因为一直在纠结用f133还是t113,在两者之间徘徊,所以才想测试一下性能,以便决定以后用哪个

MemoryPerf 不知道能不能在RV上跑，没测试

rtt里面建立任务的时候会自动分配cpu还是需要人为去指定
或者能不能一个任务两个核一起来用,

默认会自动分配吧，也可以绑定。你这跑分，可以改下代码，同时跑2份core_mark看看部分。
