3431 5770 d 6 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5770 d 17 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5771 d 5 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3035 5878 d 15 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5878 d 17 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3014 5881 d 18 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
2902 5897 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  
2899 5898 d 6 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 5907 d 5 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5927 d 9 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 5931 d 17 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5931 d 17 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5933 d 7 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5934 d 13 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5934 d 17 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5934 d 18 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5943 d 11 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6185 d 8 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.		  
2446 6243 d 11 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.		  
2227 6296 d 21 h decky /trunk/kernel/ start shutdown infrastructure
