701 6794 d 23 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 6795 d 8 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6797 d 5 h bondari /kernel/trunk/ Frame alloc test #1  
687 6797 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 6797 d 6 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6797 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 6797 d 7 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
677 6801 d 3 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6801 d 3 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
654 6816 d 4 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 6821 d 2 h decky /kernel/trunk/ init task loading (yet buggy)  
625 6821 d 5 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 6821 d 6 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6821 d 11 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 6823 d 10 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
596 6825 d 21 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6826 d 2 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6826 d 3 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6826 d 3 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 6827 d 23 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
564 6828 d 22 h jermar /kernel/trunk/ Send in some improvements.  
552 6829 d 23 h palkovsky /kernel/trunk/ Named spinlocks  
548 6830 d 2 h jermar /kernel/trunk/ Cleanup and fixes.  
541 6830 d 22 h jermar /kernel/trunk/generic/src/mm/ Get rid of junk.  
539 6831 d 2 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
538 6831 d 3 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 6831 d 4 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 6832 d 0 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6832 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6832 d 2 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 6832 d 2 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6844 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6844 d 23 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.		  
490 6851 d 5 h jermar /SPARTAN/trunk/generic/src/mm/ Fix typo and clean up comments.  
489 6851 d 5 h jermar /SPARTAN/trunk/generic/ Make the buddy system more general.
Store implementation defined pointer in buddy_system_t.
Pass buddy system pointer to implementation defined buddy system operations.		  
488 6851 d 11 h bondari /SPARTAN/trunk/generic/src/mm/ Small fix :)  
487 6851 d 11 h bondari /SPARTAN/trunk/generic/src/mm/ Frame isect/coalesce functions optimization  
480 6854 d 1 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.  
479 6855 d 2 h bondari /SPARTAN/trunk/generic/ Buddy system implementation. Not functional yet - only framework prepeared.
Also added 2 macros FRAME2ADDR and ADDR2FRAME.		  
458 6858 d 9 h decky /SPARTAN/trunk/ make configuration variables usage consistent
