3149 5871 d 0 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 5891 d 21 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5892 d 22 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5903 d 3 h decky /branches/dynload/ added dynload branch  
2504 6193 d 18 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 6251 d 21 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 6305 d 7 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6306 d 17 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6370 d 0 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 6374 d 0 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6374 d 17 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6374 d 19 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6374 d 20 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6374 d 21 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6375 d 20 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6375 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6386 d 16 h jermar /trunk/ (c) versus (C)  
2039 6421 d 0 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6511 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1820 6559 d 13 h decky /trunk/kernel/generic/ initial security context support
