755 6748 d 3 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
754 6748 d 4 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.		  
740 6754 d 13 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
735 6756 d 11 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
727 6759 d 6 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6761 d 7 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6763 d 7 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 6763 d 9 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6763 d 10 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6763 d 11 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6763 d 12 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6765 d 11 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6765 d 15 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 6768 d 5 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 6768 d 14 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6770 d 11 h bondari /kernel/trunk/ Frame alloc test #1  
687 6770 d 12 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6770 d 13 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6770 d 13 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 6770 d 13 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
678 6774 d 7 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6774 d 9 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6774 d 9 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6774 d 15 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6774 d 16 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6775 d 6 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6776 d 7 h vana /kernel/trunk/ i8042 bug fix...  
668 6779 d 12 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 6784 d 3 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6786 d 5 h decky /kernel/trunk/ initial syscall table support  
659 6787 d 17 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6789 d 10 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 6790 d 3 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 6790 d 5 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 6791 d 5 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 6792 d 4 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6793 d 4 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
