743 6729 d 12 h jermar /kernel/trunk/arch/ sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.		  
742 6729 d 12 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
741 6729 d 12 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 6729 d 18 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6731 d 15 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
730 6732 d 15 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
728 6734 d 10 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
727 6734 d 11 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
726 6734 d 11 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
724 6736 d 12 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
717 6738 d 14 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
716 6738 d 15 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6738 d 15 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
714 6738 d 15 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6738 d 16 h decky /kernel/trunk/ "Hello world" from user space :)  
710 6738 d 17 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry  
704 6740 d 17 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6740 d 20 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 6740 d 21 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
700 6743 d 19 h jermar /kernel/trunk/arch/sparc64/include/ Remove fmath.h  
699 6743 d 20 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
696 6745 d 13 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6745 d 14 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6745 d 15 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
693 6745 d 15 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
691 6745 d 16 h jermar /kernel/trunk/arch/ Cleanup.  
690 6745 d 16 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
689 6745 d 16 h bondari /kernel/trunk/ Frame alloc test #1  
687 6745 d 17 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
685 6745 d 18 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6745 d 18 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 6745 d 19 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
680 6749 d 10 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
674 6749 d 21 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6750 d 11 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
672 6751 d 11 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6751 d 12 h vana /kernel/trunk/ i8042 bug fix...  
670 6751 d 15 h vana /kernel/trunk/arch/ia32/src/drivers/ i8042 command word init... It should work on ia32 but I have done it for Indy and I'm not sure it will work because on Silicon should not be the same software in universal microprocesor i8042. So if It will not work I'll remove it and will write i8042 AT function emulation.  
669 6754 d 10 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
667 6755 d 14 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Rename saving_handler() to preemptible_handler()
and fix it to make sparc64 kernel preemptive.
Add two handlers for two fatal exceptions (i.e.
instruction_access_exception and mem_address_not_aligned.
Fix panic_printf() to not allocate its own register window.
