| help |
| The thread analysis takes quite a long time. |
| Every thread it finds is analyzed word by word to find any that |
| does not match the magic number. |
| Normally while thread are analyzed the k_thread_foreach function |
| is used. |
| While this is a safe run from the thread list perspective it may lock |
| the interrupts for a long time - long enough to disconnect when |
| Bluetooth communication is used. |
| Setting this flag will force thread analyzer to use |
| the k_thread_foreach_unlocked function. |
| This will allow the interrupts to be processed while the thread is |
| analyzed. |
| For the limitation of such configuration see the k_thread_foreach |
| documentation. |
