Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED. |

Move list and fifo data types to adt/. |
|

Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB. |

frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed |

Still better locking - does not hold global spinlock when
destroying cache. |
|

6770 d 7 h |

/kernel/trunk/ |
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|

6770 d 11 h |

/kernel/trunk/generic/ |
Added more granular locking to slab allocator and thus fix
hopefully last race condition. |
|
| 771 |
6771 d 3 h |

/kernel/trunk/generic/ |
Implemented malloc/free as SLABs. |
|

Partially working SLAB CPU cache. |
|

Basic SLAB (without CPU-cache) passes test. |
|
| 764 |
6772 d 10 h |

Tested basic non-cached slab allocation. |
|

Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|

Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference |

Skeleton of SLAB allocator. |

Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |
|

/kernel/trunk/ |
Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created. |
|
| 754 |
6775 d 2 h |
jermar |
/kernel/trunk/generic/ |
Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas. |

Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs. |
|

New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |

interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in |
|

/kernel/trunk/ |
Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping(). |

Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table. |

/kernel/trunk/ |
Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface. |

Console command 'zone' now takes zone address as parameter.

Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists. |
|
| 623 |
6821 d 16 h |
jermar |
/kernel/trunk/ |
Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed. |

Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed. |
