684 6834 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 6834 d 14 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
677 6838 d 10 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6838 d 10 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
654 6853 d 11 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 6858 d 9 h decky /kernel/trunk/ init task loading (yet buggy)  
625 6858 d 12 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 6858 d 13 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6858 d 18 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 6860 d 17 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
596 6863 d 4 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6863 d 9 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6863 d 10 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6863 d 10 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 6865 d 6 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
564 6866 d 5 h jermar /kernel/trunk/ Send in some improvements.  
552 6867 d 6 h palkovsky /kernel/trunk/ Named spinlocks  
548 6867 d 9 h jermar /kernel/trunk/ Cleanup and fixes.  
541 6868 d 5 h jermar /kernel/trunk/generic/src/mm/ Get rid of junk.  
539 6868 d 9 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
538 6868 d 10 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 6868 d 11 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 6869 d 7 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6869 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6869 d 9 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 6869 d 9 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6881 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6882 d 6 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 6888 d 12 h jermar /SPARTAN/trunk/generic/src/mm/ Fix typo and clean up comments.  
489 6888 d 12 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 6888 d 18 h bondari /SPARTAN/trunk/generic/src/mm/ Small fix :)  
487 6888 d 18 h bondari /SPARTAN/trunk/generic/src/mm/ Frame isect/coalesce functions optimization  
480 6891 d 8 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.  
479 6892 d 10 h bondari /SPARTAN/trunk/generic/ Buddy system implementation. Not functional yet - only framework prepeared.
Also added 2 macros FRAME2ADDR and ADDR2FRAME.		  
458 6895 d 16 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6902 d 6 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
413 6917 d 5 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
391 6930 d 6 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
389 6930 d 17 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
381 6935 d 6 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.
