756 6691 d 11 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
755 6692 d 10 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 6692 d 11 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.		  
752 6692 d 19 h jermar /kernel/trunk/generic/include/ Replace % operator by explicit overflow test to make this ADT compile on ia64.  
747 6696 d 12 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 6698 d 20 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
735 6700 d 18 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6701 d 17 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6701 d 17 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
727 6703 d 13 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6705 d 14 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6707 d 14 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 6707 d 16 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
714 6707 d 17 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6707 d 18 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6707 d 19 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6709 d 19 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6709 d 22 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 6712 d 12 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 6712 d 22 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6714 d 18 h bondari /kernel/trunk/ Frame alloc test #1  
687 6714 d 19 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6714 d 20 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6714 d 20 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 6714 d 20 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6714 d 23 h jermar /kernel/trunk/ Minor changes.  
678 6718 d 14 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6718 d 16 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6718 d 16 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6718 d 22 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6718 d 23 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6719 d 13 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6720 d 14 h vana /kernel/trunk/ i8042 bug fix...  
669 6723 d 12 h jermar /kernel/trunk/ sparc64 work.
kconsole support.

659 6732 d 0 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6733 d 17 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 6734 d 10 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
