748 6753 d 7 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6754 d 0 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 6754 d 9 h jermar /kernel/trunk/ Page hash table modifications.  
744 6755 d 2 h jermar /kernel/trunk/arch/ia64/ Remove ia64 boot as it is not needed by the simulator.  
743 6756 d 2 h jermar /kernel/trunk/arch/ sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.		  
742 6756 d 2 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
741 6756 d 3 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 6756 d 8 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6758 d 5 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
730 6759 d 5 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
728 6761 d 0 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
727 6761 d 1 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
726 6761 d 1 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
724 6763 d 2 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
717 6765 d 4 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
716 6765 d 5 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6765 d 5 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
714 6765 d 5 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6765 d 6 h decky /kernel/trunk/ "Hello world" from user space :)  
710 6765 d 8 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry  
704 6767 d 7 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6767 d 10 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().		  
702 6767 d 11 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
700 6770 d 9 h jermar /kernel/trunk/arch/sparc64/include/ Remove fmath.h  
699 6770 d 10 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
696 6772 d 4 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6772 d 4 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6772 d 5 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
693 6772 d 5 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff

685 6772 d 8 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6772 d 8 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.		  
682 6772 d 9 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build

672 6778 d 1 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.
