444 6765 d 15 h vana /SPARTAN/trunk/arch/ia64/ Context restore in HEAVYWEIGHT handlers  
443 6765 d 16 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 6765 d 17 h vana /SPARTAN/trunk/arch/ia64/src/ sp should not be decremented after last save  
441 6765 d 17 h jermar /SPARTAN/trunk/arch/ia64/src/ r12 (stack pointer) must be descremented prior to storing data into new memory stack frame.  
439 6766 d 13 h jermar /SPARTAN/trunk/arch/ia64/src/ Two small ia64 improvements.  
438 6766 d 14 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 6767 d 9 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.		  
434 6769 d 8 h jermar /SPARTAN/trunk/arch/ia64/src/ Fix switch variable.  
433 6769 d 8 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 6769 d 9 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.		  
431 6769 d 18 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.		  
416 6784 d 16 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.
Flush RSE before setting ar.bspstore so that ar.bsp is set to the same address.		  
414 6785 d 20 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 6 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.		  
412 6786 d 20 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S.		  
388 6800 d 17 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.		  
368 6812 d 16 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
322 6825 d 7 h jermar /SPARTAN/trunk/arch/ia64/ Reduce IA-64 context_t according to IA-64 ABI.

Make IA-64 port compile again.		  
309 6827 d 20 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
272 6830 d 12 h vana /SPARTAN/trunk/arch/ia64/ Symtab support for ia64
