A question: I need to find out the pid of the irq process that handles a particular audio device from the information available from udev (to dynamically change its rt priority). AFAICT that is not really possible. I can find the irq number easily but if there is more than one device using that number then I'm sort of stuck. The naming of the irq processes for each card appear to be hardwired strings in the driver code that do not necessarily correspond to any other name in the driver itself. Is there a connection between the two somewhere in /sys, /proc or anywhere else that I'm missing? (ie: which interrupt process corresponds to which driver?) -- Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
