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... |

Kernel doxygen comments updated. |

/kernel/trunk/ |
Make use of thread_join_timeout() and thread_detach() in kernel.
Improved comments in slab.h. |

/kernel/trunk/ |
Function for destroying address space for which there is no other reference in the kernel. |
|
| 1428 |
6583 d 21 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. |
|

Make address space backend data a union. |
|
| 1424 |
6584 d 2 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 |
6584 d 6 h |
jermar |
/kernel/trunk/ |
Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
| 1417 |
6585 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. |

6586 d 11 h |

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

6586 d 22 h |

/kernel/trunk/generic/ |
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|
| 1411 |
6587 d 3 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. |
|
| 1409 |
6587 d 21 h |
jermar |
/kernel/trunk/generic/ |
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends. |
|
| 1387 |
6590 d 5 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. |

page_ht_lock into mutexes. |

/kernel/trunk/generic/ |
Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly. |

6606 d 8 h |

/kernel/trunk/ |
Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided. |
|

Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute. |
|
| 1238 |
6615 d 3 h |
jermar |
/kernel/trunk/generic/ |
Rename SYS_AS_AREA_SHARE_APPROVE and SYS_AS_AREA_SHARE_PERFORM, resp., to
SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND, resp. in syscall_t.
Fix prototype of as_area_send() to take only base address of the address
space area as a parameter and read size and flags from the address space
area found at this base address. |
|
| 1236 |
6615 d 8 h |

/kernel/trunk/generic/ |
Add frame_reference_add(). |
|

Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM. |
|

SYS_AS_AREA_SHARE_PERFORM syscalls. |
|

Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows. |

CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp(). |
|

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well. |
