564 6917 d 19 h jermar /kernel/trunk/ Send in some improvements.  
540 6919 d 19 h jermar /kernel/trunk/arch/ Map all available frames of memory on ia32 and amd64 (ticket #10).  
537 6920 d 1 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 6920 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6920 d 23 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 6920 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6933 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
371 6994 d 20 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 6995 d 5 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
267 7013 d 3 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 7014 d 1 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 7014 d 1 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
235 7015 d 2 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
187 7017 d 5 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.		  
182 7017 d 9 h cejka /SPARTAN/trunk/ Test for printf added.  
177 7018 d 6 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 7057 d 4 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
139 7058 d 1 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 7062 d 20 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 7101 d 18 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.
