[ Please cc me on answer, I'm not subscribed to the list, I tried to ask this question on the #linux-rt channel but got no answers so I try on the list ] Hello, with 2.6.33.2-rt13 the IRQ handler thread for serial devices is no longer persistent after its creation. Up to now I had a startup script opening the serial device in order to create the IRQ handler thread that would run chrt on $(pidof IRQ-4) and the setting would be persistent until next reboot. This is no longer possible, I would have to run chrt every time that I open the serial port and I would like to avoid modifying all my applications to do this. Is there any other alternative like making the thread persistent with some options (/sys or /proc tuning)? Or is there a kernel config option for this ? In case it was not clear, I want to run the IRQ handler of the serial ports at a higher priority than the other ones (like network, disk, etc.) to avoid buffer overruns.
