727 6831 d 21 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
726 6831 d 21 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
724 6833 d 22 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
717 6836 d 1 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
716 6836 d 1 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6836 d 1 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
714 6836 d 2 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6836 d 2 h decky /kernel/trunk/ "Hello world" from user space :)  
710 6836 d 4 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry  
704 6838 d 3 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6838 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().		  
702 6838 d 7 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
700 6841 d 5 h jermar /kernel/trunk/arch/sparc64/include/ Remove fmath.h  
699 6841 d 6 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
696 6843 d 0 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6843 d 0 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6843 d 1 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
693 6843 d 1 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
691 6843 d 3 h jermar /kernel/trunk/arch/ Cleanup.  
690 6843 d 3 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
689 6843 d 3 h bondari /kernel/trunk/ Frame alloc test #1  
687 6843 d 3 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
685 6843 d 4 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6843 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.		  
682 6843 d 5 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
680 6846 d 21 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
674 6847 d 8 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6847 d 21 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
672 6848 d 21 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6848 d 22 h vana /kernel/trunk/ i8042 bug fix...  
670 6849 d 2 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 6851 d 21 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
667 6853 d 0 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.		  
666 6854 d 22 h jermar /kernel/trunk/ sparc64 work.
Fix clean_window trap handler so that it clears output registers instead of input registers!
Fix interrupt handlers to save global registers.		  
665 6855 d 7 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6856 d 18 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6857 d 7 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Initial interrupt_vector_trap handler and fixes needed to make it do the right thing (i.e. panic()).		  
659 6860 d 8 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6860 d 8 h jermar /kernel/trunk/arch/sparc64/include/ sparc64 work.
Add functions to read and write TICK and TICK_compare registers.
Add types describing TICK and TICK_compare registers.		  
657 6860 d 20 h jermar /kernel/trunk/ sparc64 work.
Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and
registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7).
