How can a thread map memory to itself
Hi All, I want to do cap/mem mapping without IPC to another thread. In particular, I want a thread to map its own memory or capability to itself. How can I achieve this? Thank you. Yuxin

You need a capability to the respective task for this. You can always obtain a capability to your own task object using L4Re::This_task. With this task capability you can then use the task::map() operation to map capabilities or memory pages to the respective task.
