ISR Preemption IIC

Hi, 

 

Is it possible to use ISR preemption with the Interal Interrupt Controller (IIC) of the NIOS II processor with the Enhanced Interrupt API? 

 

With the old API (now Legacy Interrupt API) I could use the functions alt_irq_interruptible() and alt_irq_non_interruptible() to control ISR preemption of a higher priority ISR.  

With the new API this functions are deprecated and I did not find a way to enable the ISR preemption with the IIC.  

 

Thanks for your answers!
