519 6746 d 0 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 6751 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
478 6762 d 4 h jermar /SPARTAN/trunk/ Re-aply mistakenly reverted changes.  
477 6762 d 7 h vana /SPARTAN/trunk/ Atomic inc & dec functions synchronized on all ia32,ia64 and mips platforms. Now there are 3 versions which returns no value, new value and old value och changed variable.  
476 6762 d 9 h jermar /SPARTAN/trunk/arch/ia64/ ia64 CPU identification.  
475 6763 d 7 h jermar /SPARTAN/trunk/ Define atomic_t type.  
472 6764 d 7 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.		  
470 6764 d 20 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.		  
445 6766 d 6 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix SP_DELTA alignment.
Cosmetics.		  
444 6766 d 6 h vana /SPARTAN/trunk/arch/ia64/ Context restore in HEAVYWEIGHT handlers  
443 6766 d 8 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack.		  
435 6768 d 0 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.		  
433 6769 d 23 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix definition of __u32.
Add more register manipulation functions.
Add unions describing bit-structured registers.
Distinguish between timer, unhandled and spurious external interrupts.
Initialize interval timer to generate first timer interrupt.		  
432 6770 d 1 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.		  
431 6770 d 9 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.		  
415 6785 d 8 h jermar /SPARTAN/trunk/arch/ia64/include/ Make context_set() reset ar.pfs.pfm (especially ar.pfs.pfm.sol) so that register stack does not underflow.  
414 6786 d 12 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 6786 d 22 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
403 6794 d 1 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6794 d 10 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.
