3203 5778 d 15 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3191 5784 d 13 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3190 5784 d 14 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3155 5798 d 10 h svoboda /branches/dynload/ Make loader less chatty and let init use it, instead of loading binaries itself.

3004 5819 d 12 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5820 d 12 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5830 d 17 h decky /branches/dynload/ added dynload branch  
2802 5870 d 16 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.
 
2745 5908 d 15 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2712 5934 d 13 h decky /trunk/kernel/ prettyprint output  
2632 5996 d 2 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6121 d 8 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 6179 d 11 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.
 
2436 6181 d 7 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
