1179 6610 d 18 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 6610 d 19 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.
 
1150 6619 d 2 h 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.
 
1148 6619 d 13 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6619 d 13 h jermar /kernel/trunk/generic/ 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.
 
1108 6631 d 13 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1076 6636 d 22 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1070 6637 d 1 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1048 6637 d 21 h 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.
 
1044 6637 d 23 h jermar /kernel/trunk/ Page table locking.  
1026 6638 d 12 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
983 6639 d 20 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6639 d 21 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.
 
977 6639 d 21 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6639 d 23 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
840 6666 d 22 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
823 6673 d 12 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6673 d 13 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 6673 d 23 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
792 6675 d 21 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
789 6676 d 14 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 6676 d 17 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
786 6676 d 19 h bondari /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 6677 d 16 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
771 6678 d 12 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
762 6679 d 21 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
757 6680 d 15 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 6681 d 11 h jermar /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 6682 d 11 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 6682 d 12 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 6693 d 13 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
718 6697 d 14 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
 
711 6697 d 19 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6699 d 19 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.
 
703 6699 d 22 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
