2851 6048 d 5 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix locking order in udebug_rp_end (to the somewhat unintuitive threads_lock => t->debug_lock => t->lock  
2850 6048 d 6 h svoboda /branches/tracing/uspace/app/ Initial support for multithreaded tasks in sctrace. Replace debug1 test.  
2849 6048 d 6 h svoboda /branches/tracing/kernel/generic/src/udebug/ Move code for verifying and locking down a thread for a debugging op to _thread_op_begin()/_thread_op_end(). Rewritten to prevent case of mistaken task identity  
2848 6048 d 15 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2842 6049 d 9 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix and document verify_thread()  
2841 6049 d 9 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add verify_thread() to check that a thread is valid for debug ops  
2840 6049 d 9 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 6049 d 9 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2838 6049 d 12 h svoboda /branches/tracing/ Respond to pending GO messages with UDEBUG_EVENT_FINISHED on terminating the debugging session. Set retval for DEBUG_END answer.  
2837 6049 d 15 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 6049 d 17 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2835 6049 d 17 h svoboda /branches/tracing/ Improve UDEBUG_M_END handling, switch sctrace to async API  
2834 6050 d 4 h svoboda /branches/tracing/kernel/generic/src/udebug/ Handle UDEBUG_M_END call, fix check in udebug_syscall_event()  
2833 6050 d 5 h svoboda /branches/tracing/ Remove buffer size argument from ARGS_READ call.  
2832 6050 d 8 h svoboda /branches/tracing/ Add separate syscall tracing program (sctrace), displaying correct number of arguments and return value decoding  
2827 6053 d 16 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 6053 d 17 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 6053 d 17 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2824 6053 d 18 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use intermediate buffers for handling REGS_READ, REGS_WRITE and THREADS_READ  
2823 6053 d 19 h svoboda /branches/tracing/kernel/generic/src/udebug/ Improve locking in udebug.c and udebug_ipc.c
