300 6893 d 12 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6893 d 12 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
285 6894 d 14 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
280 6895 d 0 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6895 d 2 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
271 6895 d 7 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
267 6895 d 8 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 6895 d 11 h cejka /SPARTAN/trunk/ E option in printf added.  
243 6896 d 9 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 6897 d 8 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
232 6897 d 8 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
222 6897 d 15 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 6898 d 0 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
177 6900 d 12 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 6901 d 3 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6904 d 3 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
149 6934 d 4 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 6940 d 7 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 6945 d 2 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 6984 d 0 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.
