2131 6440 d 14 h decky /branches/ add development branches  
2087 6496 d 14 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6506 d 11 h jermar /trunk/ (c) versus (C)  
1888 6631 d 14 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1793 6693 d 20 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1787 6696 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6703 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6724 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1303 6759 d 13 h palkovsky /kernel/trunk/arch/ zone_merge_all must be called after frame_init is completed - otherwise
new zone information can be allocated over the not-yet-blacklisted areas.
 
1224 6775 d 17 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.
 
1221 6776 d 8 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6782 d 18 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
925 6817 d 21 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
822 6849 d 8 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 6849 d 9 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 6849 d 19 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
778 6853 d 12 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
703 6875 d 18 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 6880 d 13 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
625 6904 d 15 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 6912 d 8 h jermar /kernel/trunk/ Send in some improvements.  
540 6914 d 8 h jermar /kernel/trunk/arch/ Map all available frames of memory on ia32 and amd64 (ticket #10).  
537 6914 d 14 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 6915 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6915 d 12 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 6915 d 12 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6927 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
371 6989 d 9 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 6989 d 18 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
267 7007 d 15 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 7008 d 14 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 7008 d 14 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
235 7009 d 15 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
187 7011 d 18 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.
 
182 7011 d 22 h cejka /SPARTAN/trunk/ Test for printf added.  
177 7012 d 19 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.
 
146 7051 d 17 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
139 7052 d 14 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 7057 d 9 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 7096 d 6 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.
