Bottom half of your driver code is the were you can take advantage of the SMP feature.You can use either workqueue(which is a simpler interface which will create number threads based on the cpu count ),but if U want finer control you can use Kthread(which does'nt inherits parents sigmask and VM) or kernel_thread, depending on your need.

(but you failed to provide a URL to even your Makefile but also to your code so it's hard to give you a detailed recommendation) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ ------------------------------------------------------------------------- Using Tomcat but need to do more?
