747 6751 d 22 h jermar /kernel/trunk/ ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).

Add missing header to sparc64.
Remove excessive header from debug.h.		  
740 6754 d 6 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
735 6756 d 4 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6757 d 3 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6757 d 3 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
727 6758 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6761 d 0 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6763 d 0 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 2 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6763 d 3 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6763 d 4 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6763 d 5 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6765 d 5 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6765 d 8 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 6767 d 22 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 8 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6770 d 4 h bondari /kernel/trunk/ Frame alloc test #1  
687 6770 d 5 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 6 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6770 d 6 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 6 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6770 d 9 h jermar /kernel/trunk/ Minor changes.  
678 6774 d 0 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6774 d 2 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6774 d 2 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6774 d 8 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6774 d 9 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6774 d 23 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6776 d 0 h vana /kernel/trunk/ i8042 bug fix...  
669 6778 d 22 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6779 d 5 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 6783 d 20 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6785 d 22 h decky /kernel/trunk/ initial syscall table support  
659 6787 d 10 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6789 d 3 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 6789 d 20 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 6790 d 22 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 6791 d 22 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6792 d 21 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.
