3433 5733 d 17 h svoboda /branches/tracing/kernel/ Move kbox handling code into a separate module.  
3431 5733 d 18 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3428 5734 d 5 h svoboda /branches/tracing/ sctrace: pass task ID as a command-line argument  
3426 5734 d 5 h svoboda /branches/tracing/kernel/generic/src/ Fix compile errors.  
3425 5734 d 5 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5734 d 17 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3127 5831 d 17 h svoboda /branches/tracing/kernel/generic/src/ Fix rounding error in as_debug_write() - prevent panic when writing on page boundary  
3108 5836 d 5 h svoboda /branches/tracing/ Split part of mips32 debugging into a genarch/idec directory for use with other trap-flag-less arches.  
3042 5840 d 1 h svoboda /branches/tracing/ Merged latest trunk changes to tracing.  
3037 5840 d 6 h svoboda /branches/tracing/kernel/generic/src/ipc/ Detach kb_thread after joining it.  
3036 5840 d 22 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 5842 d 3 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5842 d 5 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3033 5842 d 18 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix tasks_lock being released too soon in ipc_connect_kbox()  
3032 5842 d 18 h svoboda /branches/tracing/kernel/generic/src/udebug/ Move ipc_answer()s into THREAD->udebug.lock mutexes, slightly simplifying udebug_stoppable_begin()  
3031 5842 d 19 h svoboda /branches/tracing/kernel/generic/src/udebug/ Describe mutual exclusion with code executed in interrupt handler (No deadlocks can actually occur anymore)  
3030 5842 d 20 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 5843 d 1 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 5844 d 22 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
3016 5845 d 2 h svoboda /branches/tracing/kernel/generic/ Synchronize debug ops on a task with a mutex instead of task->lock spinlock.  
3015 5845 d 4 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
3014 5845 d 6 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
3013 5845 d 6 h svoboda /branches/tracing/kernel/generic/ Bypass area write-protection for udebug memory writes.  
3011 5846 d 17 h svoboda /branches/tracing/ Merged latest trunk changes to tracing  
2925 5858 d 6 h svoboda /branches/tracing/ Merged latest trunk changes to tracing branch  
2921 5860 d 6 h svoboda /branches/tracing/kernel/ Add TRAP debug event. Support on ia32/amd64.  
2919 5860 d 6 h svoboda /branches/tracing/kernel/generic/ Simlify and fix REGS_READ and REGS_WRITE operations  
2918 5860 d 17 h svoboda /branches/tracing/ Add support for INT3 breakpoints on IA32 to kernel. UDEBUG_EVENT_BREAKPOINT  
2917 5860 d 17 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: Must drop missed wakeups when waiting for go  
2913 5860 d 21 h svoboda /branches/tracing/kernel/generic/src/ Print less debugging messages to make things go faster  
2908 5860 d 23 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 5861 d 4 h svoboda /branches/tracing/ Rename event NEW_THREAD to THREAD_B. Add THREAD_E event - thread exit  
2902 5861 d 5 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 5861 d 18 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  
2900 5861 d 18 h svoboda /branches/tracing/kernel/generic/src/udebug/ Remove superfluous malloc return value checks  
2899 5861 d 18 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2898 5861 d 20 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 5861 d 22 h svoboda /branches/tracing/kernel/generic/ Fix bad allocation with locks held in udebug_thread_read()  
2896 5861 d 23 h svoboda /branches/tracing/kernel/generic/src/udebug/ Handle malloc return values properly  
2894 5862 d 0 h svoboda /branches/tracing/ Add missing copyright messages
