892 6827 d 1 h vana /kernel/trunk/ Itanium active keyboard  
879 6827 d 23 h vana /kernel/trunk/arch/ia64/ Itanium kernel page extended to maximum (256M) repaired RR manipulation functions, paging setuping function and added some comments.  
872 6830 d 17 h vana /kernel/trunk/ Init stack base fix
Removing commented code		  
870 6830 d 18 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6830 d 18 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
840 6838 d 4 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
830 6843 d 4 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().

This time, hopefully, with correct synchronization.		  
819 6844 d 21 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6845 d 1 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
816 6845 d 4 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
815 6845 d 5 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
813 6845 d 18 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.		  
793 6847 d 3 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
792 6847 d 3 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
786 6848 d 2 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		  
762 6851 d 4 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
758 6851 d 19 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.		  
757 6851 d 21 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 6852 d 18 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.		  
753 6854 d 1 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
751 6854 d 3 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6856 d 1 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6857 d 1 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6857 d 19 h jermar /kernel/trunk/ ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).

Add missing header to sparc64.
Remove excessive header from debug.h.		  
746 6858 d 4 h jermar /kernel/trunk/ Page hash table modifications.  
742 6859 d 21 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
740 6860 d 3 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6862 d 0 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
728 6864 d 19 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
726 6864 d 20 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
716 6868 d 23 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6869 d 0 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
684 6876 d 3 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
674 6880 d 6 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.
