300 6872 d 6 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6872 d 7 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
285 6873 d 9 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
280 6873 d 19 h decky /SPARTAN/trunk/arch/ia32/ basic GRUB memory map  
279 6873 d 21 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
271 6874 d 2 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
267 6874 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		  
264 6874 d 6 h cejka /SPARTAN/trunk/ E option in printf added.  
243 6875 d 4 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 6876 d 2 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
232 6876 d 3 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
222 6876 d 10 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 6876 d 19 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
177 6879 d 7 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 6879 d 22 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6882 d 22 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
149 6912 d 23 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 6919 d 2 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
125 6923 d 21 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 6962 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.
