3536 5714 d 15 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3471 5752 d 19 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3433 5760 d 11 h svoboda /branches/tracing/kernel/ Move kbox handling code into a separate module.  
3431 5760 d 11 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5760 d 23 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5761 d 10 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3042 5866 d 19 h svoboda /branches/tracing/ Merged latest trunk changes to tracing.  
3036 5867 d 15 h svoboda /branches/tracing/kernel/generic/ Make sure area written by debugger is private and anonymous by copying it, if necessary. (Not atomic atm)  
3035 5868 d 20 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5868 d 22 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3026 5869 d 18 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 5871 d 15 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
3016 5871 d 20 h svoboda /branches/tracing/kernel/generic/ Synchronize debug ops on a task with a mutex instead of task->lock spinlock.  
3015 5871 d 21 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
3014 5871 d 23 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
3013 5872 d 0 h svoboda /branches/tracing/kernel/generic/ Bypass area write-protection for udebug memory writes.  
2925 5884 d 23 h svoboda /branches/tracing/ Merged latest trunk changes to tracing branch  
2921 5886 d 23 h svoboda /branches/tracing/kernel/ Add TRAP debug event. Support on ia32/amd64.  
2919 5887 d 0 h svoboda /branches/tracing/kernel/generic/ Simlify and fix REGS_READ and REGS_WRITE operations  
2918 5887 d 10 h svoboda /branches/tracing/ Add support for INT3 breakpoints on IA32 to kernel. UDEBUG_EVENT_BREAKPOINT  
2903 5887 d 22 h svoboda /branches/tracing/ Rename event NEW_THREAD to THREAD_B. Add THREAD_E event - thread exit  
2902 5887 d 23 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 5888 d 11 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 5888 d 12 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2898 5888 d 13 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()  
2897 5888 d 16 h svoboda /branches/tracing/kernel/generic/ Fix bad allocation with locks held in udebug_thread_read()  
2894 5888 d 17 h svoboda /branches/tracing/ Add missing copyright messages  
2887 5894 d 20 h svoboda /branches/tracing/kernel/ Split executive parts of udebug_ipc.c to udebug_ops.c  
2885 5894 d 23 h svoboda /branches/tracing/ Start moving debug method processing to kbox_thread. Start with BEGIN, END, THREAD_READ  
2870 5897 d 10 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2867 5897 d 16 h svoboda /branches/tracing/ Signal hash of new thread with a UDEBUG_EVENT_NEW_THREAD message  
2866 5897 d 22 h svoboda /branches/tracing/kernel/generic/ Verify that thread is waiting in syscall event when reading syscall args  
2848 5916 d 21 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2839 5917 d 14 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2838 5917 d 17 h svoboda /branches/tracing/ Respond to pending GO messages with UDEBUG_EVENT_FINISHED on terminating the debugging session. Set retval for DEBUG_END answer.  
2833 5918 d 10 h svoboda /branches/tracing/ Remove buffer size argument from ARGS_READ call.  
2827 5921 d 21 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 5921 d 22 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5921 d 22 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2818 5922 d 13 h svoboda /branches/tracing/kernel/generic/ Add MEM_WRITE debug method for writing a task's memory
