Subj : How to debug pthread in Linux 2.4? To : comp.programming.threads From : SteveCheng Date : Wed Feb 23 2005 08:22 pm We have an embedded Linux kernel 2.4.17 with Linuxthreads library. We have a user space thread pending a select() function call which should be activated by an event from a kernel space driver. The problem is that it never got activated even driver did send out an event via wake_up_interruptible() functin call. If we changed the thread to a process, then everything works fine. So it'll be very helpful to dump more information about the thread such as how many threads are running, their status, and so on. We can't make the GDB work on this target yet. Is there any thread information we can get from the kernel? Thanks a lot, Steve .
