2902 5943 d 9 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 5943 d 22 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 5952 d 21 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5973 d 0 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 5977 d 8 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5977 d 9 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5978 d 22 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5980 d 4 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5980 d 9 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5980 d 10 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5989 d 2 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6230 d 23 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 6289 d 3 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 6342 d 12 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6343 d 22 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6407 d 5 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 6411 d 6 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6411 d 23 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6412 d 1 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6412 d 1 h decky /trunk/kernel/ spinlock extern declaration macro
