Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.). |

Remove unneeded FRAME_PANIC.
Fix some things broken by last commit. |

Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling. |

/kernel/trunk/ |
Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares... |

Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place. |

/kernel/trunk/generic/src/mm/ |
Fixed frame allocator to allocate correct number of frames for configuration.
(It couldn't fail before, but in some circumstances it could allocate more
then needed). |

Fast framebuffer scrolling in kconsole. Eats some memory though. |

Fixed error in page number computing, that could almost never appear. |

Never ever walk a B+tree as you destroy it. Or vice versa. |

/kernel/trunk/ |
task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space. |
|

Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator. |

Remove left over piece of code for increasing reference count in ELF backend. |
|

Add reference to shared frames of ELF image backed address space area. |
|

6652 d 12 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Add reference to shared frames of anonymous address space area. |

Slightly better behaviour with caching on memory sharing. |

Fixed warning about unused variable in non-debug mode. |

Remove three infinite loops introduced yesterday :-)
Make ia64 ready to load 5 ELF images. |
|
1483 |
6654 d 12 h |
jermar |
/kernel/trunk/generic/src/ |
Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management. |
|
1468 |
6655 d 10 h |

/kernel/trunk/ |
Function for destroying address space for which there is no other reference in the kernel. |
|

Slightly changed semantics of AS_AREA_SEND/RECV. |
|

6658 d 6 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Fix used_space_insert() to correctly service an empty used_space B+tree. |
|
1436 |

jermar |
/kernel/trunk/generic/src/mm/ |
Fight TLB inconsistency by proper placing of tlb_shootdown_start() and tlb_shootdown_finalize() in as.c. |
|
1434 |
6658 d 8 h |

/kernel/trunk/ |
Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform. |
|
1428 |
6659 d 4 h |
palkovsky |
/kernel/trunk/generic/ |
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. |
|
1426 |
6659 d 5 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Support for sharing address space areas backed up by ELF image. |
|
1425 |
6659 d 6 h |
jermar |
/kernel/trunk/generic/ |
Make address space backend data a union. |
|
1424 |
6659 d 9 h |
jermar |
/kernel/trunk/ |
Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now. |
|
1423 |

/kernel/trunk/ |
Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
1417 |
6661 d 5 h |
jermar |
/kernel/trunk/generic/ |
Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.
The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes. |
|
1415 |
6661 d 17 h |

/kernel/trunk/generic/ |
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount |
|
1413 |
6662 d 4 h |

/kernel/trunk/generic/ |
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|
1411 |
6662 d 9 h |
jermar |
/kernel/trunk/ |
Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault. |
|

6663 d 3 h |

/kernel/trunk/generic/ |
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends. |
|

/kernel/trunk/generic/src/mm/ |
Fixes of the used_space management code.
Switch as_area_destroy() and as_area_resize() to use the used_space map.
as_area_steal() not switched as it will undergo further changes. |
