Hi Rinat,
2. You are correct. The root process should copy the relevant caps to the cspace of process 1 and/or process 2. Note that capability space and memory space are two different concepts. The problem is not that they don't share a memory space, the problem is that they don't share a capability space.
1. Generally, the root task is responsible for managing and distributing all capabilities. However, it is possible to instantiate an allocman for each process.

Hi all,
- Could you check if my thoughts are right?
The allocation manager is global object and there is only one instance for whole system. If I need in creation kernel objects I should create _one_ allocman above some array of memory.
- I have the first question because I work with processes now. In the
root process I create two different processes based on the elf image via allocman. Then I try to manage (suspend, change priority, etc.) process1 by process2. But I can't get process1 object from process2 because both of them belong to root process and belong to root process' memory space. As I understand it, I should copy cap which belongs to process1 to process2, then I will be able to manage them. Could you tell me if I am right?
