Tracking Linux kworker threads

-
How to find out which part of kernel/module has created this workqueue. How to track a kworker-thread named for example ''kworker/0:3 to its origin in kernel-space? I found  this thread on lkml  that answers your question a little. (It seems even Linus himself was puzzled as to how to find out the origin of those threads.) Basically, there are two ways of doing this: $ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event $ cat /sys/kernel/debug/tracing/trace_pipe > out.txt (wait a few secs) For this you will need  ftrace  to be compiled in your kernel, and to enable it with: mount -t debugfs nodev /sys/kernel/debug More information on the function tracer facilities of Linux is available in the  ftrace.txt documentation . This will output what threads are all doing, and is useful for tracing multiple small jobs. cat /proc/THE_OFFENDING_KWORKER/stack This will output the stack of a single thread doing a lot of work. It may allow you

Asynchronus I/O (AIO) in vxworks and Linux

-
In generic Asynchronus I/O (AIO) can be designed using User lavel or in Kernel level. In user level 1) Process needs async callback/notification create another thread and process which goes to sleep on blocking calls (read/write/ioctls/select) 2) One Async master handler (process/thread) keeps track.All the process needs the service submit job to them.The master handler handles the async fd in Blocking mode and reply to requesting processes (or call the callback function) using some async notificatin like signal. In Kernel Level 1) Call some system call and submit some job to kernel workQ .After work is complete kernel notify using signal to user space.   In VxWorks :  aioPxLib provide the POSIX 1003.1b standard.Which is task implementation of aio service. functions available: 1) aio_read() - initiate an asyn. read. 2) aio_write() - initiate an syn write 3) aio_listio() - Initiate a aio list upto LIO_MAX 4) aio_error() - Get an aio error status. 5) aio_return() - Get a
