Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute. |
|
| 1238 |
6600 d 10 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. |
|

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

6600 d 16 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. |
|

Do not allow zero size address space areas. |
|
| 1227 |
6603 d 11 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. |
|

6614 d 10 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 |
6614 d 11 h |
jermar |
/kernel/trunk/ |
Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM. |

jermar |
/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. |

jermar |
/kernel/trunk/generic/ |
Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages. |

Page table locking. |
|

Support only anonymous address space areas. |
|

Small speed update of ipc.
Fixed some bugs regarding pages in mremap. |

6670 d 14 h |
jermar |
/kernel/trunk/ |
Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64. |
|
| 823 |
6677 d 4 h |
jermar |
/kernel/trunk/ |
Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization. |
|
| 822 |
6677 d 5 h |
palkovsky |
/kernel/trunk/ |
Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones. |
|
| 814 |
6677 d 15 h |
palkovsky |
/kernel/trunk/ |
Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print. |
|
| 792 |
6679 d 13 h |
jermar |
/kernel/trunk/ |
Page hash table architectures now use generic hash table to manage
mappings. |
|
| 789 |
6680 d 6 h |
palkovsky |
/kernel/trunk/generic/ |
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. |
|
| 788 |
6680 d 9 h |
jermar |
/kernel/trunk/ |
Move list and fifo data types to adt/. |
|

6680 d 11 h |

/kernel/trunk/ |
frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed |
|
| 778 |
6681 d 8 h |
palkovsky |
/kernel/trunk/ |
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|
| 771 |
6682 d 4 h |
palkovsky |
/kernel/trunk/generic/ |
Implemented malloc/free as SLABs. |
|
| 762 |
6683 d 14 h |
palkovsky |
/kernel/trunk/ |
Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference |
|
| 757 |
6684 d 7 h |
jermar |
/kernel/trunk/ |
Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64. |
|
| 756 |
6685 d 4 h |

/kernel/trunk/ |
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |
|
| 755 |
6686 d 3 h |
jermar |
/kernel/trunk/ |
Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created. |
|
| 754 |
6686 d 4 h |
jermar |
/kernel/trunk/generic/ |
Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas. |
|
| 727 |
6697 d 5 h |
jermar |
/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|
| 718 |
6701 d 6 h |
decky |
/kernel/trunk/ |
interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in |
|

6701 d 11 h |
decky |
/kernel/trunk/generic/src/mm/ |
fix wrong frame memory access |
