279 7002 d 18 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
271 7002 d 23 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
267 7003 d 1 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		  
264 7003 d 4 h cejka /SPARTAN/trunk/ E option in printf added.  
243 7004 d 2 h palkovsky /SPARTAN/trunk/ Resolved mapping of e820 boot area, so that it can be accessed as
e820table from 32-bit mode and e820table_boot from real mode.		  
235 7005 d 0 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
232 7005 d 1 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
222 7005 d 8 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 7005 d 17 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
177 7008 d 5 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.		  
176 7008 d 20 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 7011 d 20 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
149 7041 d 21 h jermar /SPARTAN/trunk/ Fix IA-32's get_memory_size() to return size of memory in bytes instead of in kilobytes.
Some cosmetics in memory map detection.
The IA-32 kernel is functional again.		  
139 7048 d 0 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 7052 d 19 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 7091 d 16 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.		  
112 7091 d 20 h jermar /SPARTAN/trunk/ Define two placeholder functions for atomic_inc and atomic_dec on IA-64.

Add Ondrej Palkovsky to doc/AUTHORS.

Tweaks in IA-32 low level code to bring SMP back to life. (SMP still broken)		  
110 7093 d 2 h jermar /SPARTAN/trunk/ SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.

MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment.		  
105 7095 d 17 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.		  
101 7102 d 0 h cejka /SPARTAN/trunk/arch/ia32/src/boot/ Small bug in e820 memmap function repaired.
