501 6923 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
334 6995 d 5 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.		  
300 7001 d 5 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
279 7002 d 20 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
271 7003 d 1 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
269 7003 d 1 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
267 7003 d 2 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		  
244 7004 d 2 h decky /SPARTAN/trunk/arch/ia32/src/ temporarily fix IA-32 boot bug  
232 7005 d 2 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
195 7006 d 22 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option		  
167 7018 d 5 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.		  
144 7047 d 4 h vana /SPARTAN/trunk/ Coding style fix  
143 7047 d 5 h vana /SPARTAN/trunk/ Disable alignment check  
141 7047 d 5 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
125 7052 d 20 h jermar /SPARTAN/trunk/ Huge indentation fix.  
113 7091 d 17 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 21 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 3 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 18 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.		  
84 7110 d 6 h vana /SPARTAN/trunk/ IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.

Build script for IA-32 changed to build floppy images (image.bin) 1440K long.
