task_* APIs are unavailable in kernel build mode, replacing with posix_spawn or pthread_* API to pass the case. But posix_spawn requires some dependency, for example CONFIG_BUILTIN and CONFIG_LIBC_EXECFUNCS, so pthread_* APIs are used in most scenarios. Some tests should be re-visited because the intent is to user another task (in this case another process) to e.g. receive signals. That will require quite a bit of extra work. Tests that had to be disabled: - restart: task_restart() does not work at all with kernel mode so it is disabled entirely - fpu: make sure the FPU test is not even attempted, because it will cause ASSERT() and stop the test - vfork: vfork() does not work for some reason in CONFIG_BUILD_KERNEL, there is something missing on the kernel side, so just disable the test for now Tests that should be re-visited: - The signal tests, now they signal the process itself while before the signal was sent to another task. This will require building the part that receives the signal as a separate process - waitpid: Like stated above, waitpid does not work for pthreads - suspend: kill to send signal does not work for pthreads Signed-off-by: fangxinyong <fangxinyong@xiaomi.com> Co-authored-by: Ville Juven <ville.juven@unikie.com>
