749 6736 d 2 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6737 d 3 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6737 d 20 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 6738 d 5 h jermar /kernel/trunk/ Page hash table modifications.  
741 6739 d 22 h jermar /kernel/trunk/ Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.		  
740 6740 d 4 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
730 6743 d 1 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6744 d 21 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
715 6749 d 1 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
710 6749 d 3 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry  
703 6751 d 6 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().		  
699 6754 d 6 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
691 6756 d 2 h jermar /kernel/trunk/arch/ Cleanup.  
684 6756 d 4 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 6760 d 7 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6775 d 1 h jermar /kernel/trunk/arch/ Compilation fixes.  
627 6780 d 2 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.		  
625 6780 d 3 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
583 6785 d 4 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.		  
581 6785 d 7 h palkovsky /kernel/trunk/ Small debug changes.  
577 6785 d 17 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
569 6786 d 20 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
564 6787 d 20 h jermar /kernel/trunk/ Send in some improvements.  
537 6790 d 2 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
- truncating black list addresses to frame boundaries
- removal of left-over obsolete structures
- fixing some comments

532 6790 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
521 6797 d 6 h vana /kernel/trunk/arch/ia64/ Coding style patch.  
520 6797 d 21 h vana /kernel/trunk/arch/ia64/ Lost files from last commit.  
519 6797 d 21 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)

478 6814 d 2 h jermar /SPARTAN/trunk/ Re-aply mistakenly reverted changes.  
477 6814 d 5 h vana /SPARTAN/trunk/ Atomic inc & dec functions synchronized on all ia32,ia64 and mips platforms. Now there are 3 versions which returns no value, new value and old value och changed variable.  
476 6814 d 6 h jermar /SPARTAN/trunk/arch/ia64/ ia64 CPU identification.  
475 6815 d 5 h jermar /SPARTAN/trunk/ Define atomic_t type.

At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.		  
470 6816 d 18 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.

443 6818 d 5 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack.		  
435 6819 d 22 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
