1780 6750 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1246 6818 d 4 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 6818 d 23 h jermar /kernel/trunk/arch/ This time really fix wrong definition of K_DATA_START.  
1241 6818 d 23 h jermar /kernel/trunk/arch/ Fix K_DATA_START section definition.  
693 6927 d 3 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
534 6962 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6962 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6974 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6988 d 8 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
406 7014 d 23 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 7052 d 8 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.  
298 7052 d 8 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
291 7053 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 7053 d 22 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
267 7054 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 7056 d 5 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
177 7059 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 7135 d 4 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 7142 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 7143 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)
