Hello, I see that it is possible to have 1 thread with multiple stacks, using alloc_secondary_stack() call. But if I want to switch stack From one OS thread to another one for setcontext()?
Stack do contain hidden data related to Stack structure and to the native UCB (completely opaque). If I try to use it, it try to find stored structure which contains thread reference, which point to old thread. I need to point it to the new thread
In particular , it interfere with thread local storage TLS data, it use wrong content from old thread because it use stack content for thread identification , and fail…
How to do this, any ideas? I can’t re-create it - it contains state of the thread , not the best idea to copy content of stack during every context switch …
