4605 6085 d 5 h decky /branches/snapshot/ add task snapshoting branch  
3983 6208 d 4 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3620 6306 d 8 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3566 6321 d 9 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3438 6373 d 7 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 6444 d 3 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3068 6479 d 4 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2504 6789 d 0 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 6847 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 6900 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6901 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6965 d 6 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 6969 d 6 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6969 d 23 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6970 d 1 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6970 d 2 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6970 d 3 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6971 d 2 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6971 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6981 d 22 h jermar /trunk/ (c) versus (C)
