Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA. |

Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided. |

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

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

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

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 |
6666 d 23 h |
palkovsky |
/kernel/trunk/generic/ |
Still better locking - does not hold global spinlock when
destroying cache. |
|
| 780 |

/kernel/trunk/ |
Small fix in slab allocator for large-sized slabs. |
|
| 778 |
6667 d 6 h |

/kernel/trunk/ |
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|
| 776 |
6667 d 10 h |

/kernel/trunk/generic/ |
Added more granular locking to slab allocator and thus fix
hopefully last race condition. |
|
| 775 |
6667 d 11 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. |
|

/kernel/trunk/ |
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. |

Implemented malloc/free as SLABs. |
|
| 769 |
6668 d 22 h |

/kernel/trunk/ |
SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception. |
|

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

Partially working SLAB CPU cache. |
|
| 766 |

Basic SLAB (without CPU-cache) passes test. |
|

Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |
|
| 764 |

Tested basic non-cached slab allocation. |
|
| 763 |
6669 d 10 h |

Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|
| 762 |
6669 d 11 h |

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

Skeleton of SLAB allocator. |
