There are new_thread_handler and fork_handler in "arch/um/kernel/process.c". gprof catchs the new_thread_handler function, but there is no sign about fork_handler. Because the two functions are in the same file, so it is not kernel configuration issue. I'm sure the two functions have been executed. And new_thread_handler call a few functions, such as, kernel_init and kthreadd. gprof catch kthreadd but missing kernel_init. I traced the UML kernel with gdb, so I'm sure kernel_init called by new_thread_handler. I search with google, but failed to get useful information about gprof missing function issue. Is there any clue/suggestion how to make gprof catch all functions? thanks ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
