/branches/tracing/kernel/generic/src/udebug/ |
Describe mutual exclusion with code executed in interrupt handler (No deadlocks can actually occur anymore) |

/branches/tracing/kernel/generic/src/udebug/ |
Add a preliminary check, so that performance of undebugged multithreaded tasks doesn't suffer on SMP |
|

/branches/tracing/kernel/generic/ |
Convert THREAD->udebug.lock to mutex. Protect against udebug_before_thread_runs() called from interrupt handler. Pending locking scheme change (multithreaded tasks may hang) |
