4220 5612 d 8 h decky /trunk/kernel/ update for string changes  
4013 5643 d 17 h svoboda /trunk/kernel/generic/ Didn't need strrcpy() afterall. Also remove strcpy() since strncpy() is better.  
4011 5643 d 19 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3988 5644 d 18 h svoboda /trunk/kernel/generic/src/proc/ Fix misaligned columns (whoops).  
3987 5644 d 19 h svoboda /trunk/kernel/ Read command line for multiboot modules on ia32 and copy it to task name. Other arches will need to initialize task names in the init structure to an empty string.  
3983 5645 d 1 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3908 5657 d 21 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3896 5659 d 16 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3875 5661 d 20 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3790 5697 d 4 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3734 5712 d 2 h decky /trunk/kernel/generic/src/proc/ coding style  
3620 5743 d 5 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3617 5743 d 23 h svoboda /trunk/kernel/generic/ Fix race that allowed Udebug to report THREAD_B events for threads already reported with THREAD_READ.  
3581 5754 d 17 h jermar /trunk/kernel/ Some cstyle.  
3578 5755 d 8 h vana /trunk/ Alfa of SMP support on IA64  
3566 5758 d 6 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5758 d 17 h svoboda /trunk/ Fix sys_thread_create(): could fail when passed name was at end of mapping, could crash if provided name was not null-terminated.  
3438 5810 d 4 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3359 5834 d 5 h jermar /trunk/kernel/generic/src/proc/ Improve comments in task.c  
3222 5881 d 0 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3186 5895 d 21 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.		  
3181 5898 d 5 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3137 5905 d 4 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3104 5913 d 8 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3063 5916 d 1 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created		  
3062 5916 d 1 h decky /trunk/kernel/generic/src/proc/ proper printf formatting  
2907 5938 d 0 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2802 5975 d 5 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2790 5981 d 6 h jermar /trunk/kernel/generic/src/proc/ Fix typo ALV tree vs. AVL tree.  
2765 6001 d 20 h jermar /trunk/kernel/generic/src/proc/ tasklet.c needs to include config.h  
2746 6012 d 23 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 6013 d 4 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2712 6039 d 2 h decky /trunk/kernel/ prettyprint output  
2632 6100 d 15 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6225 d 21 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 6226 d 2 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.		  
2487 6252 d 21 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6271 d 18 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().		  
2451 6280 d 20 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6284 d 0 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.
