Use less frames for zone configuration data after merge. |

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization. |
|

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. |

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

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

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/. |
|

/kernel/trunk/generic/ |
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 |
6820 d 1 h |
palkovsky |
/kernel/trunk/generic/ |
Still better locking - does not hold global spinlock when
destroying cache. |
|
780 |
6820 d 5 h |
palkovsky |
/kernel/trunk/ |
Small fix in slab allocator for large-sized slabs. |
|
778 |
6820 d 7 h |
palkovsky |
/kernel/trunk/ |
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|
776 |
6820 d 11 h |
palkovsky |
/kernel/trunk/generic/ |
Added more granular locking to slab allocator and thus fix
hopefully last race condition. |
|
775 |
6820 d 12 h |
palkovsky |
/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 |
6822 d 0 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 |
6822 d 11 h |

Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|
762 |
6822 d 12 h |

Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference |
|
759 |

Skeleton of SLAB allocator. |
|

Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64. |
|

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. |
|
755 |
6825 d 2 h |

/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 |
6825 d 3 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. |
|
