Slightly changed semantics of AS_AREA_SEND/RECV. |
|

Reference counting for futexes. |
|

6740 d 20 h |

/kernel/trunk/generic/include/ |
Added error code for timeouts. |

Correct realtime clock communication. |
|

6741 d 1 h |

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

6741 d 8 h |

/kernel/trunk/generic/ |
Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate. |

Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired. |

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. |

Make address space backend data a union. |
|

/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. |

Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
| 1417 |
6743 d 22 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. |

Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change. |

Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount |
|

6744 d 21 h |

/kernel/trunk/generic/ |
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|
| 1411 |
6745 d 2 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. |
|

6745 d 20 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/ |
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. |
