2825 5912 d 22 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5914 d 12 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5915 d 18 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5915 d 22 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5916 d 0 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5924 d 16 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6166 d 13 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 6224 d 16 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 6278 d 2 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6279 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6342 d 19 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.		  
2105 6346 d 19 h decky /trunk/kernel/ move ipc structures to ipc.h
