3031 6002 d 7 h svoboda /branches/tracing/kernel/generic/src/udebug/ Describe mutual exclusion with code executed in interrupt handler (No deadlocks can actually occur anymore)  
3030 6002 d 7 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add a preliminary check, so that performance of undebugged multithreaded tasks doesn't suffer on SMP  
3026 6002 d 12 h svoboda /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)  
3018 6004 d 9 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
3016 6004 d 14 h svoboda /branches/tracing/kernel/generic/ Synchronize debug ops on a task with a mutex instead of task->lock spinlock.  
3015 6004 d 15 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
3014 6004 d 17 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
2921 6019 d 18 h svoboda /branches/tracing/kernel/ Add TRAP debug event. Support on ia32/amd64.  
2918 6020 d 4 h svoboda /branches/tracing/ Add support for INT3 breakpoints on IA32 to kernel. UDEBUG_EVENT_BREAKPOINT  
2917 6020 d 4 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: Must drop missed wakeups when waiting for go  
2913 6020 d 9 h svoboda /branches/tracing/kernel/generic/src/ Print less debugging messages to make things go faster  
2908 6020 d 10 h svoboda /branches/tracing/kernel/generic/src/udebug/ Don't wait for another GO in THREAD_E event, terminate debugging of this thread instead  
2903 6020 d 16 h svoboda /branches/tracing/ Rename event NEW_THREAD to THREAD_B. Add THREAD_E event - thread exit  
2902 6020 d 17 h svoboda /branches/tracing/kernel/generic/ Implement proper kbox thread shutdown, with all bells and whistles. Use THREAD->debug_active in udebug_stoppable_xx() and friends  
2901 6021 d 5 h svoboda /branches/tracing/ Split SYSCALL event into SYSCALL_B and SYSCALL_E, the extra event allows seeing long-running syscalls immediately, as well as calls with invalid syscall id  
2899 6021 d 6 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2898 6021 d 7 h svoboda /branches/tracing/ Implement operation UDEBUG_M_STOP that stops a thread. Can be used for stopping program by hitting a key in debugger. Somewhat jittery demo in sctrace. Fix missing lock of THREAD->debug_lock in udebug_stoppable_end()  
2894 6021 d 11 h svoboda /branches/tracing/ Add missing copyright messages  
2870 6030 d 4 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2867 6030 d 10 h svoboda /branches/tracing/ Signal hash of new thread with a UDEBUG_EVENT_NEW_THREAD message
