1246 6729 d 5 h vana /kernel/trunk/arch/ia32/src/smp/ This patch enables 32 base of GDT on APs at boot. It should now be able to use GDTs allocated up of 16MB so I hope this patches AP crash bug ocurred in some memory configurations.  
1242 6730 d 0 h jermar /kernel/trunk/arch/ This time really fix wrong definition of K_DATA_START.  
1241 6730 d 0 h jermar /kernel/trunk/arch/ Fix K_DATA_START section definition.  
693 6838 d 3 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
534 6873 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6873 d 2 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6885 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6899 d 9 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
406 6926 d 0 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.		  
300 6963 d 8 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 6963 d 9 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
291 6964 d 1 h jermar /SPARTAN/trunk/arch/ia32/src/smp/ AP cpus are not supposed to touch A20 for this bit is enabled by the BSP cpu.  
279 6964 d 23 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
267 6965 d 5 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		  
232 6967 d 5 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
177 6970 d 9 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.		  
117 7046 d 5 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.		  
113 7053 d 20 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 7054 d 0 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 7055 d 6 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.
