756 6696 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.		  
753 6697 d 18 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
751 6697 d 21 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6699 d 18 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6700 d 19 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6701 d 12 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 6701 d 21 h jermar /kernel/trunk/ Page hash table modifications.  
742 6703 d 14 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
740 6703 d 20 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
728 6708 d 12 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
726 6708 d 13 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
716 6712 d 17 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6712 d 17 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
684 6719 d 20 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 6754 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6754 d 15 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 6754 d 15 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6766 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
368 6828 d 21 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
