3665 6401 d 20 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 6416 d 20 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3492 6451 d 0 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3343 6507 d 2 h decky /branches/sparc/ add sparc branch  
3222 6549 d 3 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3068 6584 d 4 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2504 6894 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 6952 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 7005 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2216 7006 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 7070 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 7074 d 6 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 7074 d 23 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 7075 d 1 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 7075 d 2 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 7075 d 3 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 7076 d 2 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 7076 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 7086 d 23 h jermar /trunk/ (c) versus (C)  
2039 7121 d 7 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task
