Hi List! I have a some trouble with the task creation in l4ka. What I want/should do, is creating a task within the root task without using the rmgr. That means, I have to copy the text area of the new task in some memory region and I also have to allocate some memory for the stack. After this, I want to create the new task with the `l4_new_task` call. The problem now is, that I only have pointers dependent on the local address space of root task which I can give as input. Since the newly created task has its own address space these pointers are not useful. Anyhow, if I use them, the new task is created and running but while executing its code a page fault occurs, founded in the fact, that the new task is trying to get a page allocated by the root task.
Am I barking up the wrong tree? Are there any simple solutions for that?
If you have a look at some of the code in Kenge (http://www.l4hq.org/projects/env/kenge), you should see some example code on how to do this kind of thing. If the code there isn't clear please let me know and I can help you.
