4013	5579 d 9 h	svoboda	/trunk/kernel/generic/	Didn't need strrcpy() afterall. Also remove strcpy() since strncpy() is better.
4011	5579 d 10 h	svoboda	/trunk/kernel/	String functions should be declared in string.h (and implemented in string.c) in the kernel.
3988	5580 d 10 h	svoboda	/trunk/kernel/generic/src/proc/	Fix misaligned columns (whoops).
3987	5580 d 11 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	5580 d 17 h	svoboda	/trunk/	task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.
3908	5593 d 13 h	decky	/trunk/	overhaul pareas: use one single physical area for the physical address space not belonging to physical memory
3620	5678 d 21 h	svoboda	/trunk/kernel/generic/	Move stuff related to kbox to a separate struct.
3566	5693 d 22 h	svoboda	/trunk/	Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.
3438	5745 d 19 h	svoboda	/trunk/	Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.
3359	5769 d 21 h	jermar	/trunk/kernel/generic/src/proc/	Improve comments in task.c
3222	5816 d 15 h	svoboda	/trunk/	Merge program-loader related stuff from dynload branch to trunk. (huge)
3186	5831 d 13 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.
3137	5840 d 20 h	jermar	/trunk/kernel/generic/src/proc/	Maintain cache coherence after sys_task_spawn() copies ELF image from user space.
3063	5851 d 17 h	decky	/trunk/kernel/generic/src/proc/	support for SYS_SPAWN syscall proper printf formatting change the way init tasks are created
2802	5910 d 20 h	jermar	/trunk/kernel/generic/	Fix initialization of answerbox->task in ipc_answerbox_init. Contributed by Jiri Svoboda.
2745	5948 d 20 h	decky	/trunk/	code cleanup (mostly signed/unsigned) allow extra compiler warnings
2712	5974 d 17 h	decky	/trunk/kernel/	prettyprint output
2632	6036 d 7 h	decky	/trunk/kernel/generic/src/proc/	try to kill the tasks fewer times by introducing a delay in iterations
2504	6161 d 12 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	6219 d 16 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.
