1150 6616 d 9 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 6616 d 19 h jermar /kernel/trunk/generic/include/mm/ s/B+-tree/B+tree/  
1148 6616 d 19 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6616 d 19 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.
 
1146 6618 d 3 h decky /boot/trunk/arch/ppc32/loader/ add instruction cache flush
align framebuffer on 128K boundary
change OFW calling method
make OFW code more compatible
 
1145 6618 d 3 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1144 6618 d 23 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.
 
1143 6619 d 2 h palkovsky /uspace/trunk/libc/ Added support for multithreading (using futexes) into malloc.  
1142 6619 d 7 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 6620 d 4 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.
 
1140 6620 d 23 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 6620 d 23 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6624 d 1 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 6624 d 4 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1136 6624 d 23 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 6625 d 19 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
1134 6626 d 2 h jermar /kernel/trunk/generic/src/adt/ Change B+-tree to:
- store lesser keys in a key's left subtree
- propagate the bigger of medians (if there are two medians) when splitting a node
 
1133 6626 d 21 h decky /boot/trunk/arch/ppc32/loader/ ofw uses \r\n as newline  
1132 6626 d 22 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1131 6626 d 22 h decky /boot/trunk/arch/ppc32/loader/ kernel boot API change
