2902 5920 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 5921 d 6 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 5930 d 5 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5950 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 5954 d 17 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5954 d 17 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5956 d 7 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5957 d 13 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5957 d 17 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5957 d 18 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5966 d 11 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6208 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 6266 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 6319 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6321 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6384 d 14 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 6388 d 14 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6389 d 7 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6389 d 9 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6389 d 10 h decky /trunk/kernel/ spinlock extern declaration macro
