4691 5555 d 1 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
4344 5666 d 23 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5666 d 23 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
3674 5811 d 22 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3569 5839 d 9 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3448 5890 d 10 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3203 5964 d 8 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3190 5970 d 7 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3149 5984 d 7 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 6005 d 4 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 6006 d 5 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 6016 d 10 h decky /branches/dynload/ added dynload branch  
2746 6094 d 3 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2504 6307 d 1 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.		  
2502 6307 d 6 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.		  
2451 6362 d 0 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6365 d 4 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.		  
2440 6365 d 22 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().		  
2268 6409 d 1 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.		  
2227 6418 d 14 h decky /trunk/kernel/ start shutdown infrastructure
