Small fix in slab allocator for large-sized slabs. |
|
| 779 |

/kernel/trunk/generic/ |
Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems. |
|
| 778 |
6817 d 23 h |

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

added thread list to kconsole. |

/kernel/trunk/generic/ |
Added more granular locking to slab allocator and thus fix
hopefully last race condition. |
|
| 775 |
6818 d 4 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. |
|

6818 d 17 h |

/kernel/trunk/ |
Fixed non-initialized cpu-cache. |
|
| 771 |
6818 d 19 h |

/kernel/trunk/generic/ |
Implemented malloc/free as SLABs. |
|
| 769 |
6819 d 16 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. |
|

/kernel/trunk/ |
Debugged slab allocator. It currently supports per-CPU cache on 1 cpu. |
|
| 767 |

Partially working SLAB CPU cache. |
|
| 766 |
6819 d 21 h |

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

Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |
|
| 764 |
6820 d 2 h |

/kernel/trunk/ |
Tested basic non-cached slab allocation. |
|
| 763 |
6820 d 3 h |
jermar |
/kernel/trunk/ |
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|
| 762 |
6820 d 4 h |

/kernel/trunk/ |
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. |
|

/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 |
6822 d 19 h |

/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. |

interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)

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. |

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.
Added buddy system statistics into the 'zone' command. |
