support for more init tasks
(might break some archs yet) |

Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero. |

Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??) |

Use less frames for zone configuration data after merge. |
|

Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones. |

Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t. |

Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print. |

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

Debugged slab allocator. It currently supports per-CPU cache on 1 cpu. |

Tested basic non-cached slab allocation. |

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

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(). |

/kernel/trunk/generic/src/mm/ |
Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup. |

Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command. |

init task loading (yet buggy) |

/kernel/trunk/generic/ |
Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists. |
|
623 |
6824 d 19 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. |

Buddy allocator cleanup and fixes II.
- Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64).
- Get rid of IS_BUDDY_RIGHT_BLOCK.
- Make sparc64 use zone_create_in_region. |

Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
