/kernel/trunk/ |
Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.

Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64. |

/kernel/trunk/generic/src/mm/ |
Add some sanity checks to make sure the address space created by SYS_MAM_PHYSMEM will not be remapped
and that as_page_fault() will not try to service page fault for that area. |

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. |

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. |
|

Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list. |

Update B+-tree code.
The code is there, btree_remove() has not been tested yet.
(Fixes, if any, are to come later today.) |

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. |

CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().

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). |

/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 |
