4679 5585 d 15 h rimsky /branches/sparc/kernel/ Enhancing the way how even distribution of threads over processor cores is achieved.  
3745 5803 d 17 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5803 d 19 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5827 d 8 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5842 d 8 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3549 5855 d 8 h rimsky /branches/sparc/ Implemented uspace Serengeti drivers for kbd and fb. Integrated with other parts of HelenOS. Now it is possible to play Tetris on a simulated Serengeti machine (usiii.simics).  
3492 5876 d 12 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3343 5932 d 14 h decky /branches/sparc/ add sparc branch  
3222 5974 d 15 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3104 6007 d 0 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3063 6009 d 16 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created		  
2907 6031 d 16 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2790 6074 d 21 h jermar /trunk/kernel/generic/src/proc/ Fix typo ALV tree vs. AVL tree.  
2712 6132 d 17 h decky /trunk/kernel/ prettyprint output  
2504 6319 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.		  
2502 6319 d 17 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 6346 d 13 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6365 d 10 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 6374 d 11 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6377 d 15 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.
