3620 5705 d 5 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3566 5720 d 6 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3438 5772 d 3 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5843 d 0 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3068 5878 d 1 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2504 6187 d 20 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 6246 d 0 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 6299 d 10 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6300 d 20 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6364 d 2 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 6368 d 3 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6368 d 20 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6368 d 22 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6368 d 22 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6368 d 23 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6369 d 23 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6370 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6380 d 19 h jermar /trunk/ (c) versus (C)  
2039 6415 d 3 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6505 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
