1702 6529 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1023 6619 d 3 h vana /kernel/trunk/ Itanium FPU active context switch  
919 6625 d 9 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.		  
912 6629 d 1 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.		  
911 6629 d 5 h jermar /kernel/trunk/arch/ia64/ ia64 work.

Change heavyweight interrupt handler to use bank 0 registers instead of AR.KR0 and AR.KR1.
This prevents userspace from the possibility to see what addresses are being used by kernel.

Store kernel stack address in bank 0 r23 instead of AR.KR7. Again, userspace will not be
able to read the address of its kernel stack.

Increase FRAME_SIZE to 64K as this is the first supported page size in which will fit
thread's combined register and memory stack. (RSE can write out as many as 16K.)		  
869 6639 d 22 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
746 6667 d 7 h jermar /kernel/trunk/ Page hash table modifications.  
534 6720 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6720 d 2 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6732 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
476 6743 d 9 h jermar /SPARTAN/trunk/arch/ia64/ ia64 CPU identification.  
472 6745 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 6745 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.		  
433 6750 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 6751 d 1 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.
