735 6728 d 20 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6729 d 19 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6729 d 20 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
727 6731 d 15 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6733 d 16 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6735 d 16 h decky /kernel/trunk/ interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in		  
717 6735 d 19 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6735 d 20 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6735 d 20 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6735 d 21 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6737 d 21 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6738 d 0 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().		  
701 6740 d 14 h jermar /kernel/trunk/generic/src/mm/ Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup.		  
699 6741 d 0 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6742 d 21 h bondari /kernel/trunk/ Frame alloc test #1  
687 6742 d 21 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6742 d 22 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6742 d 22 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.		  
683 6742 d 22 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6743 d 1 h jermar /kernel/trunk/ Minor changes.  
678 6746 d 16 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6746 d 18 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6746 d 19 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6747 d 0 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6747 d 1 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6747 d 15 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6748 d 16 h vana /kernel/trunk/ i8042 bug fix...  
669 6751 d 15 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6751 d 22 h bondari /kernel/trunk/generic/src/console/ Zones related commands infrastructure for console. Also fixed small bug that caused infinite loop during command parsing  
664 6756 d 12 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6758 d 14 h decky /kernel/trunk/ initial syscall table support  
659 6760 d 2 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6761 d 19 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.		  
651 6762 d 13 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)

Fix context save/restore to save/restore register %i7.		  
646 6763 d 14 h jermar /kernel/trunk/ Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.

sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.		  
640 6764 d 14 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6765 d 13 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed.
