3983 5731 d 14 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3620 5829 d 18 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3566 5844 d 19 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3438 5896 d 17 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5967 d 13 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3068 6002 d 14 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2504 6312 d 10 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 6370 d 13 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 6423 d 23 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6425 d 9 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6488 d 16 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 6492 d 16 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6493 d 9 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6493 d 11 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6493 d 12 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6493 d 13 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6494 d 12 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6494 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6505 d 8 h jermar /trunk/ (c) versus (C)  
2039 6539 d 16 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task
