822 6655 d 4 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
820 6655 d 5 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
 
814 6655 d 15 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
778 6659 d 8 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
703 6681 d 14 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().
 
693 6686 d 9 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
625 6710 d 11 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.
 
564 6718 d 4 h jermar /kernel/trunk/ Send in some improvements.  
540 6720 d 4 h jermar /kernel/trunk/arch/ Map all available frames of memory on ia32 and amd64 (ticket #10).  
537 6720 d 10 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
 
534 6721 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6721 d 8 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 6721 d 8 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6733 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
371 6795 d 5 h jermar /SPARTAN/trunk/arch/ia32/src/ Complete map_kernel() in boot.S to map the entire 4G space.

Change IA-32 frame_arch_init() to add zone with lower base addresses first.
 
368 6795 d 14 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
267 6813 d 11 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken
 
247 6814 d 10 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Fix nasty bug in arch/mm/frame.c.
frame_region_not_free() takes address as its second argument, not size.
 
246 6814 d 10 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
235 6815 d 11 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32
