2071 7009 d 6 h jermar /trunk/ (c) versus (C)  
1787 7199 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1138 7305 d 10 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().
 
1056 7316 d 9 h jermar /kernel/trunk/arch/ia64/src/ Slightly optimized version of ivt.S.  
1053 7316 d 10 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1023 7317 d 8 h vana /kernel/trunk/ Itanium FPU active context switch  
993 7318 d 7 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.
 
979 7318 d 13 h vana /kernel/trunk/arch/ia64/ Itanium FPU context save/restore  
962 7319 d 5 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Support for __SYSCALL4.
Fix user stack initial address.
 
921 7323 d 9 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
 
919 7323 d 14 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.
 
916 7325 d 16 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.
 
915 7325 d 17 h jermar /kernel/trunk/arch/ia64/ ia64 work.
- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.
 
912 7327 d 6 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 7327 d 10 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.)
 
899 7332 d 10 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.
 
534 7418 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 7418 d 7 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 7430 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
478 7441 d 10 h jermar /SPARTAN/trunk/ Re-aply mistakenly reverted changes.  
477 7441 d 13 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.  
473 7443 d 4 h jermar /SPARTAN/trunk/arch/ia64/src/ ia64 work.
Comment some offending steps of heavyweight interrupt handler regarding RSE switching.
With this change, ia64 will do well on tests rwlock #4 and thread #1.
Cleanup.
 
472 7443 d 12 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 7444 d 1 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.
 
456 7444 d 15 h jermar /SPARTAN/trunk/arch/ia64/src/ ia64 work.
Add missing srlz_d().
Remove extra stops.
Coding style cleanups.
 
445 7445 d 11 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix SP_DELTA alignment.
Cosmetics.

443 7445 d 13 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.
 
442 7445 d 14 h vana /SPARTAN/trunk/arch/ia64/src/ sp should not be decremented after last save  
441 7445 d 14 h jermar /SPARTAN/trunk/arch/ia64/src/ r12 (stack pointer) must be descremented prior to storing data into new memory stack frame.  
439 7446 d 10 h jermar /SPARTAN/trunk/arch/ia64/src/ Two small ia64 improvements.  
438 7446 d 11 h jermar /SPARTAN/trunk/arch/ia64/src/ ia64 work.
Heavyweight handler should be complete up to the point where it switches back to interrupted RSE context.
 
435 7447 d 6 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.

Exclude external interrupt from universal_handler() scope.
 
238 7512 d 9 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions
