2497 6167 d 23 h jermar /branches/rcu/kernel/generic/src/adt/ Cleanup of the RCU branch.
Get rid of some of the code duplication in avl.c by introducing the REBALANCE()
macro and the repair() function.		  
2496 6169 d 22 h jermar /branches/rcu/kernel/generic/ Cleanup of the RCU branch.
Cleanup avl.h and avl.c a little bit.
Do we really need to have so much of code replication even within one AVL
tree implementation?		  
2466 6217 d 5 h mencl /branches/rcu/kernel/ Added forgoten favl.h and favl.c and changed balance atribute of avl
tree to int8_t.		  
2461 6219 d 23 h mencl /branches/rcu/kernel/ Added Fast avl tree structure which should be used as timeout data structure instead of simple avl tree. This
structure has much faster search min and delete min operations (constant time).		  
2456 6220 d 21 h hudecek /branches/rcu/kernel/ Model use of RCU  
2450 6223 d 1 h mencl /branches/rcu/kernel/ Repaired avl and extavl tree timeout unregister and delete_min. These
faults caused problems with initializing cpus and they appeared only in
multi processor systems.		  
2431 6229 d 21 h mencl /branches/rcu/kernel/ Repaired extavl and extavlrel data structures, added benchmark tests for avl based data structures and
simulating timeout mechanismus		  
2421 6231 d 21 h mencl /branches/rcu/kernel/ Repaired and debuged data structures and added timeout test  
2416 6232 d 21 h mencl /branches/rcu/ All timeout structures and tests added
Use timeout structures in timeout mechanism - not tested yet		  
2307 6250 d 21 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2131 6294 d 2 h decky /branches/ add development branches  
2112 6341 d 6 h decky /trunk/kernel/generic/src/adt/ explicit typecast, fix signed/unsigned comparison  
2111 6341 d 6 h decky /trunk/kernel/generic/src/adt/ fix signed/unsigned comparison  
2089 6349 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6359 d 22 h jermar /trunk/ (c) versus (C)  
1787 6550 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6557 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6571 d 6 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6575 d 8 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6577 d 7 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1704 6577 d 11 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6578 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1549 6588 d 4 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1483 6590 d 5 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 6607 d 3 h jermar /kernel/trunk/generic/src/adt/ Remove a misleading comment.  
1262 6622 d 0 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 6625 d 2 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6629 d 20 h decky /kernel/trunk/ printf-related and other code cleanup  
1200 6635 d 3 h jermar /kernel/trunk/ Add bitmap ADT.  
1196 6636 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1177 6640 d 6 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6643 d 2 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1154 6647 d 1 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 6648 d 10 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.		  
1148 6648 d 21 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6648 d 21 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 6651 d 0 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 6651 d 8 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 6653 d 0 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 6657 d 0 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).
