Hello, I am working on powerPC board latest Xenomai stable version. I am communicating between two kernel(queue1.c and queue2.c)modules using Message queues.The queue descriptor is shared between the two kernel modules by using EXPORT_SYMBOL(queue_desc). The data is sent to the user space(read.c) through message pipes. This program runs fine somtimes but sometimes the task gets suspended while starting the task.
My questions are: Is it a valid thing to pass messages through queues between two kernel modules using EXPORT_SYMBOL(queue_desc)? What are the possibilities that a task gets suspending while starting a task? Thanks & Regards, Poornima
