Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|

6664 d 5 h |

/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. |

/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. |
|

6667 d 7 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. |

ppc32: hardware memory mapping, kernel PHT refill fix |
|

6668 d 2 h |

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

6672 d 5 h |
jermar |
/kernel/trunk/generic/ |
Cleanup after removal of as_area_accept and as_area_send. |
|

/kernel/trunk/generic/ |
Added support to IPC for simple page sharing. |
|

6677 d 4 h |
jermar |
/kernel/trunk/generic/src/mm/ |
On as_area_destroy(), mark the area as partial before unlocking and free its
structure after unlocking. |
|

6677 d 6 h |

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

6683 d 10 h |
jermar |
/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. |
|
1248 |
6691 d 5 h |

/kernel/trunk/ |
Add some @file doxygen comments and improve already existing comments. |
|
1239 |
6692 d 4 h |
jermar |
/kernel/trunk/generic/ |
Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute. |
|
1238 |
6692 d 5 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 |
6692 d 10 h |
jermar |
/kernel/trunk/generic/ |
Add frame_reference_add(). |
|
1235 |
6692 d 10 h |
jermar |
/kernel/trunk/generic/ |
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. |
|
1233 |
6694 d 2 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Do not allow zero size address space areas. |
|
1227 |
6695 d 6 h |
jermar |
/kernel/trunk/ |
Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls. |
|

6706 d 5 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Add some sanity checks to make sure the address space created by SYS_MAM_PHYSMEM will not be remapped
and that as_page_fault() will not try to service page fault for that area. |
|
1178 |
6706 d 5 h |
jermar |
/kernel/trunk/ |
Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM. |

/kernel/trunk/generic/ |
Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings. |

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. |
