--- Begin Message ---Hell. I try to port a Mach microkernel on arm9 architecture. and i have a one problem - i dont understand a process of context switch in this kernel. in 2 place - when context switch acquire from thread_sleep, and next, when binary part of module loaded and this thread/task should workl. 1. when thread_call in bootstrap.c called, context switch acquire. and im looked on x86 sources, and dont see when CPU should switch in different mode for correct context switching. 2. i made small chit, and call user_bootstrap from load_context and send global thread and task information, but after loading binary part of module (exec_load) and then build_args_and_stack (), i still have in thread_stack PC point on swap_function. how module should proper load, and how and thread information change to point on this executive code? Thanks a lot.
