300 6898 d 3 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6898 d 3 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
285 6899 d 6 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
280 6899 d 16 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6899 d 17 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
271 6899 d 22 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
267 6900 d 0 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 6900 d 3 h cejka /SPARTAN/trunk/ E option in printf added.  
243 6901 d 1 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 6901 d 23 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
232 6902 d 0 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
222 6902 d 7 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 6902 d 16 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
177 6905 d 4 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 6905 d 19 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6908 d 19 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
149 6938 d 20 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 6944 d 23 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 6949 d 18 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 6988 d 15 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.
