Now I use Imx53 gpio2-14 to be a interrupt source ,but I found its priority so lower .
So I use tzic_set_irq_prio(int irq, int hi)
.................................
.............................
MY_GPIO2_14=(1*32+14)+128;
irq=irq_ to_gpio( MY_GPIO2_14);
mxc_tzic_init_irq(IMX53_TZIC_BASE_ADDR);
tzic_set_irq_prio(irq,20);//chang the priority to #30
.................................
......................................
Is it right？

How is that? All the gpio irqs have the same priority.

No. tzic_set_irq_prio is an internal function to be used by Xenomai. You
do not need to use it.

Again, you can not change the priority, all gpio irqs have the same
priority.

And you did not answer my question, what makes you think that one gpio
interrupt priority interrupt is lower than another?
