693 6926 d 1 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
680 6929 d 20 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
602 6953 d 21 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
534 6960 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6961 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6973 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
461 6987 d 6 h decky /SPARTAN/trunk/ link kernel in ARCH's native format first, then use objcopy to create output format  
457 6987 d 7 h decky /SPARTAN/trunk/ new build system almost finished  
406 7013 d 22 h jermar /SPARTAN/trunk/arch/ Fix directives for K_TEXT_START, K_TEXT_START_2 and K_DATA_START sections to be more descriptive about section's content.
Remove LOAD(0xdeadbeaf) from ia32 linker script.
Remove __fake from amd64 pm.c.		  
381 7026 d 20 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.		  
337 7045 d 5 h jermar /SPARTAN/trunk/arch/ia32/ Uncomment LONG(0xdeadbeaf) in IA-32 linker script so that the kernel is linked correctly.  
334 7045 d 6 h jermar /SPARTAN/trunk/arch/ Cleanup.
Cancel __fake in pm.c and replace it with LONG(0xdeadbeaf) in linker script. Still need some to find out why it must be there.
Remove comment saying, that mips is little-endian.		  
328 7046 d 8 h jermar /SPARTAN/trunk/ IA-32 can be now cross-compiled by ./build.ia32 cross.
Unify IA-32 Makefile.inc and Makefile.inc.cross.

Update doc/requirements.

Small changes elsewere.		  
301 7051 d 6 h palkovsky /SPARTAN/trunk/arch/ Backported amd64 build process back to ia32.  
300 7051 d 6 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
285 7052 d 9 h decky /SPARTAN/trunk/arch/ia32/ finish GRUB booting (including memory map and SMP)  
268 7053 d 2 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 7053 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		  
243 7054 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 7055 d 2 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
217 7055 d 18 h palkovsky /SPARTAN/trunk/arch/ia32/ Bugfix.  
216 7055 d 19 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
110 7143 d 4 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.		  
106 7145 d 6 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.		  
105 7145 d 19 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.		  
65 7168 d 0 h decky /SPARTAN/trunk/arch/ia32/ doxygen-style comments  
16 7199 d 2 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.		  
11 7242 d 19 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
1 7250 d 1 h jermar /SPARTAN/ Initial import
