4605 5612 d 13 h decky /branches/snapshot/ add task snapshoting branch  
4490 5641 d 8 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
3983 5735 d 12 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3896 5750 d 3 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3620 5833 d 16 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3566 5848 d 17 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5849 d 4 h svoboda /trunk/ Fix sys_thread_create(): could fail when passed name was at end of mapping, could crash if provided name was not null-terminated.  
3438 5900 d 15 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5971 d 11 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3068 6006 d 12 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2926 6025 d 17 h decky /trunk/kernel/generic/include/proc/ cs change  
2746 6103 d 10 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2504 6316 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.		  
2502 6316 d 13 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.		  
2451 6371 d 7 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6374 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.		  
2440 6375 d 6 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().		  
2268 6418 d 8 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.		  
2227 6427 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6429 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
