762 6726 d 23 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
759 6727 d 11 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
735 6737 d 20 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
724 6742 d 16 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6747 d 0 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 6749 d 14 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.
 
689 6751 d 20 h bondari /kernel/trunk/ Frame alloc test #1  
686 6751 d 21 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
683 6751 d 22 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.
 
677 6755 d 18 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6755 d 18 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
629 6775 d 17 h decky /kernel/trunk/ init task loading (yet buggy)  
624 6775 d 21 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6776 d 2 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 6778 d 1 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
564 6783 d 14 h jermar /kernel/trunk/ Send in some improvements.  
552 6784 d 15 h palkovsky /kernel/trunk/ Named spinlocks  
541 6785 d 13 h jermar /kernel/trunk/generic/src/mm/ Get rid of junk.  
539 6785 d 18 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.
 
538 6785 d 19 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 6785 d 20 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 6786 d 16 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6786 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6786 d 17 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 6786 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6798 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
489 6805 d 21 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 6806 d 2 h bondari /SPARTAN/trunk/generic/src/mm/ Small fix :)  
487 6806 d 2 h bondari /SPARTAN/trunk/generic/src/mm/ Frame isect/coalesce functions optimization  
480 6808 d 16 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.  
479 6809 d 18 h bondari /SPARTAN/trunk/generic/ Buddy system implementation. Not functional yet - only framework prepeared.
Also added 2 macros FRAME2ADDR and ADDR2FRAME.
 
430 6819 d 14 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
413 6834 d 13 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.
 
375 6856 d 20 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().  
374 6858 d 14 h jermar /SPARTAN/trunk/ Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)

Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day.
 
373 6858 d 16 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.
 
368 6860 d 23 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
367 6861 d 14 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.
 
219 6881 d 12 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.
 
195 6882 d 17 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
