2851 5938 d 2 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  
2849 5938 d 3 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 5938 d 13 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2842 5939 d 6 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix and document verify_thread()  
2841 5939 d 6 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add verify_thread() to check that a thread is valid for debug ops  
2840 5939 d 6 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 5939 d 6 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2838 5939 d 9 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 5939 d 13 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 5939 d 14 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2835 5939 d 14 h svoboda /branches/tracing/ Improve UDEBUG_M_END handling, switch sctrace to async API  
2834 5940 d 2 h svoboda /branches/tracing/kernel/generic/src/udebug/ Handle UDEBUG_M_END call, fix check in udebug_syscall_event()  
2833 5940 d 2 h svoboda /branches/tracing/ Remove buffer size argument from ARGS_READ call.  
2827 5943 d 13 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 5943 d 14 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5943 d 14 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2824 5943 d 15 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use intermediate buffers for handling REGS_READ, REGS_WRITE and THREADS_READ  
2823 5943 d 16 h svoboda /branches/tracing/kernel/generic/src/udebug/ Improve locking in udebug.c and udebug_ipc.c  
2819 5944 d 5 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: crashed caused by missing return in switch statement  
2818 5944 d 5 h svoboda /branches/tracing/kernel/generic/ Add MEM_WRITE debug method for writing a task's memory  
2817 5944 d 6 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2816 5944 d 8 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use thread-struct pointer for identification within debug connection  
2815 5944 d 8 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 5944 d 12 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2812 5944 d 12 h svoboda /branches/tracing/ Group debug IPC calls under a single method number, differentiate by ARG1  
2810 5944 d 14 h svoboda /branches/tracing/kernel/generic/src/ipc/ fix bug in debug_args_read() that caused it to only copy 6 bytes  
2809 5944 d 14 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 5945 d 4 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2807 5945 d 15 h svoboda /branches/tracing/ initial support for debugging multithreaded tasks  
2805 5946 d 9 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 5946 d 10 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2803 5946 d 12 h svoboda /branches/tracing/kernel/generic/src/proc/ fix: initialize debug fields in task structure

2800 5946 d 15 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 5946 d 16 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5955 d 8 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2765 5973 d 5 h jermar /trunk/kernel/generic/src/proc/ tasklet.c needs to include config.h  
2746 5984 d 8 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)

the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
