> Subject: [PATCH v2 1/2] trace: select TIMER_EARLY to avoid infinite recursion
>
> When tracing functions is enabled this adds calls to
> __cyg_profile_func_enter() and __cyg_profile_func_exit() to the traced
> functions.
>
> __cyg_profile_func_enter() and __cyg_profile_func_exit() invoke
> timer_get_us() to record the entry and exit time.
>
> initr_dm() will make gd->dm_root = NULL and gd->timer = NULL, so
> timer_get_us() -> get_ticks() -> dm_timer_init() will lead to an
> indefinite recursion.
>
> So select TIMER_EARLY when tracing got enabled.
