3149 5958 d 9 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 5979 d 6 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5980 d 7 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5990 d 12 h decky /branches/dynload/ added dynload branch  
2504 6281 d 3 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 6339 d 6 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 6392 d 16 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6394 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6457 d 8 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 6461 d 9 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6462 d 2 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6462 d 4 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6462 d 5 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6462 d 6 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6463 d 5 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6463 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6474 d 1 h jermar /trunk/ (c) versus (C)  
2039 6508 d 9 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6599 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1820 6646 d 22 h decky /trunk/kernel/generic/ initial security context support
