I'm not sure to understand what you mean. When thread_sleep blocks, it calls thread_block, which calls thread_invoke, which calls switch_context, which does the low-level part. In the case of continuations (i.e. there is no context to return to, the thread just needs to call a function again), stack_handoff is called instead to just switch stacks. > and i made in boot_script_exec_cmd a kernel_thread for user_bootstrap instead > of thread_create+thread_start (no doswapin), because i have a kernel_stack=0, > and cant run user_bootstrap. i think its not corrent (my solution), should i > do > it on active_stack ? You are supposed to set the value of kernel_stack in stack_attach. That will get called by thread_invoke when the new thread is scheduled for the first time (see the "Check that the thread is swapped-in." part which calls stack_alloc_try(), which calls stack_attach to attached the allocated stack).
