727 6698 d 11 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6700 d 12 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6702 d 12 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 6702 d 15 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6702 d 16 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6702 d 17 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6702 d 17 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6704 d 17 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6704 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().		  
701 6707 d 11 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 6707 d 20 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6709 d 17 h bondari /kernel/trunk/ Frame alloc test #1  
687 6709 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.		  
686 6709 d 18 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6709 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.		  
683 6709 d 19 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6709 d 21 h jermar /kernel/trunk/ Minor changes.  
678 6713 d 12 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6713 d 15 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6713 d 15 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6713 d 20 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6713 d 22 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6714 d 11 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6715 d 12 h vana /kernel/trunk/ i8042 bug fix...  
669 6718 d 11 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6718 d 18 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 6723 d 8 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6725 d 11 h decky /kernel/trunk/ initial syscall table support  
659 6726 d 22 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6728 d 16 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 6729 d 9 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)		  
650 6729 d 11 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.		  
646 6730 d 10 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 6731 d 10 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6732 d 9 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.		  
631 6733 d 12 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6733 d 14 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6733 d 15 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6733 d 17 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.		  
624 6733 d 18 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.
