792 6854 d 22 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
789 6855 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 6855 d 18 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
786 6855 d 20 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 6856 d 17 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
771 6857 d 13 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
762 6858 d 22 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
757 6859 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 6860 d 12 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 6861 d 12 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 6861 d 13 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 6872 d 14 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
718 6876 d 15 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 6876 d 20 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6878 d 20 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6878 d 23 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().
