From 6f71308ef529bfcecd54daaa309d1336ef0c6366 Mon Sep 17 00:00:00 2001 From: Grissiom Date: Fri, 11 Oct 2013 22:46:05 +0800 Subject: kernel: add RT_DEBUG_IN_THREAD_CONTEXT In thread context means: 1) the scheduler has been started; 2) not in interrupt context. It is more stronger than RT_DEBUG_NOT_IN_INTERRUPT. With this commit, you will catch the error on situations like taking mutex before scheduling instead of crashing on NULL pointer reference. --- include/rtdebug.h | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) (limited to 'include') diff --git a/include/rtdebug.h b/include/rtdebug.h index ebf85d6dba..5172778578 100644 --- a/include/rtdebug.h +++ b/include/rtdebug.h @@ -103,8 +103,29 @@ do \ rt_hw_interrupt_enable(level); \ } \ while (0) + +/* "In thread context" means: + * 1) the scheduler has been started + * 2) not in interrupt context. + */ +#define RT_DEBUG_IN_THREAD_CONTEXT \ +do \ +{ \ + rt_base_t level; \ + level = rt_hw_interrupt_disable(); \ + if (rt_thread_self() == RT_NULL) \ + { \ + rt_kprintf("Function[%s] shall not be used before scheduler start\n", \ + __FUNCTION__); \ + RT_ASSERT(0) \ + } \ + RT_DEBUG_NOT_IN_INTERRUPT; \ + rt_hw_interrupt_enable(level); \ +} \ +while (0) #else #define RT_DEBUG_NOT_IN_INTERRUPT +#define RT_DEBUG_IN_THREAD_CONTEXT #endif #else /* RT_DEBUG */ -- cgit v1.3.1
