1159 6784 d 11 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1158 6784 d 11 h jermar /kernel/trunk/generic/ Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread.		  
1156 6784 d 12 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1154 6788 d 9 h jermar /kernel/trunk/generic/src/adt/ Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized.		  
1153 6788 d 14 h jermar /kernel/trunk/generic/src/synch/ Because of another race condition, futex_wakeup() needs to be able to allocate and initialize the kernel futex structure too.  
1151 6788 d 15 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1150 6789 d 17 h jermar /kernel/trunk/generic/ Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings.		  
1149 6790 d 4 h jermar /kernel/trunk/generic/include/mm/ s/B+-tree/B+tree/  
1148 6790 d 4 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6790 d 4 h jermar /kernel/trunk/generic/ Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.		  
1145 6791 d 11 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1144 6792 d 8 h jermar /kernel/trunk/ Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.		  
1142 6792 d 15 h jermar /kernel/trunk/ Update B+-tree code.
The code is there, btree_remove() has not been tested yet.
(Fixes, if any, are to come later today.)		  
1141 6793 d 13 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.		  
1140 6794 d 8 h jermar /kernel/trunk/generic/ Change B+-tree from 2-3-4 tree to 2-3-4-5 tree by adding space for the fourth key.
This should make key removal easier.		  
1139 6794 d 8 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6797 d 10 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1137 6797 d 13 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1136 6798 d 7 h jermar /kernel/trunk/generic/src/adt/ Try to avoid splitting full B+-tree nodes by trying left or right rotation first.
(This improved memory consumption of this algorithm by some 40% - meassured on 101-item set).		  
1135 6799 d 4 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
