/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. |

Documentation and dot.bochsrc upgrade. |

Fix number of steps in softint division.
Make ia64 port compile with softint. |

/kernel/trunk/genarch/ |
Added softint for emulation 32 and 64 bit division.
Not tested yet. |

Simics GS patch even in SMP. |

/kernel/trunk/arch/amd64/src/boot/ |
I'm unsure if simics is broken or the only one according to spec,
but SYSCALL now works even with simics. |
|

/kernel/trunk/arch/amd64/ |
Added (finally!) userspace to AMD64.
It does not work on Simics *$U&%&$&*#. Broken simics!!!
There should be probably LEA instead of MOV/ADD, but LEA does not
work in neither qemu nor bochs. Any other simulator to test? :-/ |

Basic amd syscall support. |
|
| 802 |

Userspace now starts executing correctly. |
|

Split AMD interrupt.h from ia32 version. |
|

Preliminary work on AMD userspace. |

fix init_addr virtual address |

/kernel/trunk/arch/mips32/ |
Fixed uspace address constants. |
|
| 796 |
6680 d 14 h |

/kernel/trunk/ |
Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel. |
|
| 794 |
6680 d 15 h |
palkovsky |
/kernel/trunk/ |
Added MIPS userspace. Currently can't make it work in gxemul. |
|

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. |
|
| 792 |
6680 d 16 h |

Page hash table architectures now use generic hash table to manage
mappings. |
|
| 791 |

/kernel/trunk/generic/ |
better utilization of memory in slab alloc
removed malloc-8 slab |
|

Generic chaining hash table. |
|
| 789 |
6681 d 9 h |

/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. |
|
| 788 |
6681 d 12 h |

/kernel/trunk/ |
Move list and fifo data types to adt/. |
|
| 787 |
6681 d 14 h |
palkovsky |
/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. |

Cleanup of scheduler code |
|
| 783 |
6681 d 17 h |
palkovsky |
/kernel/trunk/generic/ |
Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/ |
|

/kernel/trunk/generic/src/mm/ |
Small locking performance tweak. |
|
| 781 |
6682 d 5 h |
palkovsky |
/kernel/trunk/generic/ |
Still better locking - does not hold global spinlock when
destroying cache. |
|
| 780 |
6682 d 9 h |

/kernel/trunk/ |
Small fix in slab allocator for large-sized slabs. |
|
| 779 |
6682 d 9 h |

/kernel/trunk/generic/ |
Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems. |
|
| 778 |
6682 d 11 h |
palkovsky |
/kernel/trunk/ |
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|
| 777 |
6682 d 12 h |
palkovsky |
/kernel/trunk/generic/ |
added thread list to kconsole. |
|
| 776 |
6682 d 16 h |
palkovsky |
/kernel/trunk/generic/ |
Added more granular locking to slab allocator and thus fix
hopefully last race condition. |
|
| 775 |
6682 d 17 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. |
|
| 773 |
6683 d 5 h |

/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. |
|
| 772 |
6683 d 6 h |

/kernel/trunk/ |
Fixed non-initialized cpu-cache. |
|
| 771 |
6683 d 7 h |
palkovsky |
/kernel/trunk/generic/ |
Implemented malloc/free as SLABs. |
|
| 770 |
6683 d 14 h |
palkovsky |
/kernel/trunk/generic/include/ |
Fix context_save, so that it works even with inlines disabled (-O0). |
