The priority of the irq thread can be configured. If necessary, it needs to
be used together with other strategies to prevent priority inversion.
Here is a simple example of usage
static int isrhandle(int irq, void *regs, void *arg)
{
up_disabled_irq(irq);
return IRQ_WAKE_THREAD;
}
static int isrthread(int irq, void *regs, void *arg)
{
//irq process
...
//clear irq pending bit
...
up_enabled_irq(irq);
return OK;
}
irq_attach_thread(IRQ, isrhandle, isrthread, arg, 253, 2048);
