6727 d 10 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 |
6728 d 8 h |
jermar |
/kernel/trunk/ |
Function for destroying address space for which there is no other reference in the kernel. |

/kernel/trunk/generic/ |
Slightly changed semantics of AS_AREA_SEND/RECV. |
|

6731 d 4 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Fix used_space_insert() to correctly service an empty used_space B+tree. |
|

/kernel/trunk/generic/src/mm/ |
Fight TLB inconsistency by proper placing of tlb_shootdown_start() and tlb_shootdown_finalize() in as.c. |

/kernel/trunk/ |
Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform. |
|

6732 d 2 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. |
|

6732 d 7 h |

/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. |
|

6732 d 11 h |

/kernel/trunk/ |
Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
| 1417 |
6734 d 3 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. |

/kernel/trunk/generic/ |
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount |
|

6735 d 3 h |
jermar |
/kernel/trunk/generic/ |
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|
| 1411 |
6735 d 8 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. |
|

6736 d 1 h |
jermar |
/kernel/trunk/generic/ |
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends. |
|
| 1403 |
6737 d 15 h |
jermar |
/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. |
|
| 1387 |
6738 d 9 h |
jermar |
/kernel/trunk/generic/ |
Add used_space_insert() and used_space_remove().
These are the alpha versions of functions that
will help to map used and unused portions of address
space areas. Currently unused, but many as_area operations
will be more efficient when the used space B+tree map
is used. |

Turn address space lock, address space area lock and
page_ht_lock into mutexes. |

Cleanup after removal of as_area_accept and as_area_send. |

Added support to IPC for simple page sharing. |
