3875 5592 d 3 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3734 5642 d 9 h decky /trunk/kernel/generic/src/proc/ coding style  
3617 5674 d 6 h svoboda /trunk/kernel/generic/ Fix race that allowed Udebug to report THREAD_B events for threads already reported with THREAD_READ.  
3581 5685 d 1 h jermar /trunk/kernel/ Some cstyle.  
3578 5685 d 15 h vana /trunk/ Alfa of SMP support on IA64  
3566 5688 d 13 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5689 d 0 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 5740 d 11 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5811 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3104 5843 d 16 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3063 5846 d 8 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created		  
2907 5868 d 7 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2790 5911 d 13 h jermar /trunk/kernel/generic/src/proc/ Fix typo ALV tree vs. AVL tree.  
2712 5969 d 9 h decky /trunk/kernel/ prettyprint output  
2504 6156 d 4 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 6156 d 9 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 6183 d 5 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6202 d 2 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 6211 d 3 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6214 d 7 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.
