My question is: is the particular IRQ (not other IRQs) that is handled by this ISR re-enabled after the *RT* ISR finished or is it re-enabled after the *Linux* ISR has finished. In my understanding the interrupt cannot be enabled after the RT-ISR because then the RT-ISR handler would be called again and the Linux ISR would never have a chance to run. Thanks.
