2496 6167 d 12 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 6214 d 19 h mencl /branches/rcu/kernel/ Added forgoten favl.h and favl.c and changed balance atribute of avl
tree to int8_t.		  
2461 6217 d 13 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 6218 d 11 h hudecek /branches/rcu/kernel/ Model use of RCU  
2450 6220 d 15 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 6227 d 11 h mencl /branches/rcu/kernel/ Repaired extavl and extavlrel data structures, added benchmark tests for avl based data structures and
simulating timeout mechanismus		  
2421 6229 d 11 h mencl /branches/rcu/kernel/ Repaired and debuged data structures and added timeout test  
2416 6230 d 11 h mencl /branches/rcu/ All timeout structures and tests added
Use timeout structures in timeout mechanism - not tested yet		  
2307 6248 d 11 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2131 6291 d 16 h decky /branches/ add development branches  
2112 6338 d 20 h decky /trunk/kernel/generic/src/adt/ explicit typecast, fix signed/unsigned comparison  
2111 6338 d 21 h decky /trunk/kernel/generic/src/adt/ fix signed/unsigned comparison  
2089 6346 d 20 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6357 d 12 h jermar /trunk/ (c) versus (C)  
1787 6547 d 15 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6554 d 16 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6568 d 21 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6572 d 22 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6574 d 22 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 6575 d 1 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6575 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1549 6585 d 18 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1483 6587 d 19 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 6604 d 17 h jermar /kernel/trunk/generic/src/adt/ Remove a misleading comment.  
1262 6619 d 14 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 6622 d 16 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6627 d 10 h decky /kernel/trunk/ printf-related and other code cleanup  
1200 6632 d 17 h jermar /kernel/trunk/ Add bitmap ADT.  
1196 6633 d 20 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1177 6637 d 20 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6640 d 16 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1154 6644 d 15 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 6646 d 0 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 6646 d 11 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6646 d 11 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 6648 d 14 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 6648 d 22 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 6650 d 14 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 6654 d 14 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 6655 d 17 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
