Hi, with the rt-preempt patch the IRQs are all kernelthreads started with priority 50. Is there a way to change this priority from inside the driver, after I did the request_irq() call? I need a higher priority for one interrupt source but I do not want to change it with chrt from userspace. It should be done inside the driver.
