/kernel/trunk/generic/ |
Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.

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

/kernel/trunk/ |
Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word. |

More lightweighed TLB shootdown implementation. |

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??) |
|

/kernel/trunk/ |
Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64. |

Add page_mapping_remove(). |

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

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization. |
|
822 |
6814 d 5 h |

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

/kernel/trunk/ |
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. |
|

Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile. |
|

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

/kernel/trunk/ |
Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.
Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped. |

Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations. |

Page hash table architectures now use generic hash table to manage
mappings. |

better utilization of memory in slab alloc
removed malloc-8 slab |

/kernel/trunk/generic/ |
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 |

Comments clarification. |

Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/ |

Small locking performance tweak. |
|
781 |
6818 d 2 h |

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

Small fix in slab allocator for large-sized slabs. |
|

6818 d 9 h |

/kernel/trunk/ |
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|
776 |
6818 d 13 h |
palkovsky |
/kernel/trunk/generic/ |
Added more granular locking to slab allocator and thus fix
hopefully last race condition. |
|
775 |
6818 d 14 h |

/kernel/trunk/generic/ |
Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic. |

Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu. |

Fixed non-initialized cpu-cache. |
