757 6705 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 6706 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.		  
753 6707 d 19 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
751 6707 d 21 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6709 d 19 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6710 d 19 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6711 d 13 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 6711 d 22 h jermar /kernel/trunk/ Page hash table modifications.  
742 6713 d 15 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
740 6713 d 21 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
728 6718 d 13 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
726 6718 d 14 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
716 6722 d 17 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6722 d 18 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
684 6729 d 21 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.		  
534 6764 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6764 d 16 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6764 d 16 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6776 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
368 6838 d 22 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
