740 6738 d 15 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
735 6740 d 13 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
727 6743 d 8 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6745 d 9 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6747 d 9 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		  
711 6747 d 14 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6749 d 13 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6749 d 17 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 6752 d 7 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 6752 d 17 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6754 d 13 h bondari /kernel/trunk/ Frame alloc test #1  
687 6754 d 14 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6754 d 15 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6754 d 15 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 6754 d 15 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
677 6758 d 11 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6758 d 11 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
654 6773 d 12 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.		  
629 6778 d 10 h decky /kernel/trunk/ init task loading (yet buggy)  
625 6778 d 14 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 6778 d 15 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6778 d 20 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
615 6780 d 19 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
596 6783 d 6 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6783 d 11 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6783 d 12 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6783 d 12 h palkovsky /kernel/trunk/ Move all MIPS exceptions to generic dispatcher.
Align size in malloc() to __native size, some architectures
don't like it unaligned.		  
569 6785 d 7 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
564 6786 d 7 h jermar /kernel/trunk/ Send in some improvements.  
552 6787 d 8 h palkovsky /kernel/trunk/ Named spinlocks  
548 6787 d 10 h jermar /kernel/trunk/ Cleanup and fixes.  
541 6788 d 7 h jermar /kernel/trunk/generic/src/mm/ Get rid of junk.  
539 6788 d 11 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
538 6788 d 12 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes II.
- Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64).
- Get rid of IS_BUDDY_RIGHT_BLOCK.
- Make sparc64 use zone_create_in_region.		  
537 6788 d 13 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
- truncating black list addresses to frame boundaries
- removal of left-over obsolete structures
- fixing some comments		  
536 6789 d 9 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6789 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6789 d 10 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6789 d 10 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6801 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.
