2902 5897 d 16 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 5 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 5907 d 3 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5927 d 7 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 15 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5931 d 15 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5933 d 5 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5934 d 11 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5934 d 16 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5934 d 17 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5943 d 9 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6185 d 6 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 9 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 19 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6298 d 5 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6361 d 12 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 6365 d 12 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6366 d 5 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6366 d 7 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6366 d 8 h decky /trunk/kernel/ spinlock extern declaration macro
