Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread. |

Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep(). |

/kernel/trunk/generic/src/adt/ |
Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized. |
|

Because of another race condition, futex_wakeup() needs to be able to allocate and initialize the kernel futex structure too. |

/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. |

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 |
6788 d 5 h |

/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 |
6788 d 12 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.) |
|

/kernel/trunk/generic/src/ipc/ |
Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep. |
|

/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. |
|

Fix comments. |

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(). |
|

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 |
6795 d 8 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 |
|

/kernel/trunk/generic/src/proc/ |
Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again. |
|

Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction). |
|

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well. |
|

Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths. |

Fix bug with refcounts in frame allocator after zone_merge. (it caused some
frames not to be coalesced). |
|

Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages. |

* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack. |
