/kernel/trunk/generic/src/adt/
Bitmap functions patch
1483
6707 d 6 h
jermar
/kernel/trunk/generic/src/
Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.
1337
6724 d 5 h
jermar
/kernel/trunk/generic/src/adt/
Remove a misleading comment.
1262
6739 d 1 h
jermar
/kernel/trunk/generic/src/adt/
Fix a bug caused by an unsigned subtraction of bigger value from smaller value in bitmap implementation.
Fix wrong calculation of unaligned leading bits in bitmap implementation.
1248
6742 d 3 h
jermar
/kernel/trunk/
Add some @file doxygen comments and improve already existing comments.
1221
6746 d 21 h
decky
/kernel/trunk/
printf-related and other code cleanup

6752 d 5 h
jermar
/kernel/trunk/
Add bitmap ADT.

6753 d 7 h
cejka
/kernel/trunk/
Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
1177
6757 d 8 h
jermar
/kernel/trunk/generic/
Modify B+tree node key width to be 64-bit wide on all platforms.
1164
6760 d 4 h
jermar
/kernel/trunk/generic/
Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.
1154
6764 d 3 h
jermar
/kernel/trunk/generic/src/adt/
Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized.
1150
6765 d 11 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.

s/B+-tree/B+tree/
1147
6765 d 22 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.
1144
6768 d 2 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
6768 d 9 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.)
1140
6770 d 2 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.
1136
6774 d 1 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).
1134
6775 d 5 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
