2825 5935 d 7 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2817 5935 d 22 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2808 5936 d 21 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5938 d 3 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2803 5938 d 4 h svoboda /branches/tracing/kernel/generic/src/proc/ fix: initialize debug fields in task structure  
2801 5938 d 8 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 5938 d 8 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 5938 d 9 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5947 d 1 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2765 5964 d 21 h jermar /trunk/kernel/generic/src/proc/ tasklet.c needs to include config.h  
2746 5976 d 0 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5976 d 5 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2712 6002 d 3 h decky /trunk/kernel/ prettyprint output  
2632 6063 d 16 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6188 d 22 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 6189 d 3 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 6215 d 23 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6234 d 20 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 6243 d 21 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6247 d 1 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.
