Context restore in HEAVYWEIGHT handlers

ia64 work.
Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack.
442

vana
/SPARTAN/trunk/arch/ia64/src/
sp should not be decremented after last save

/SPARTAN/trunk/arch/ia64/src/
r12 (stack pointer) must be descremented prior to storing data into new memory stack frame.
439
6856 d 2 h
jermar
/SPARTAN/trunk/arch/ia64/src/
Two small ia64 improvements.

ia64 work.
Heavyweight handler should be complete up to the point where it switches back to interrupted RSE context.
435
6856 d 21 h

ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.
434
6858 d 20 h
jermar
/SPARTAN/trunk/arch/ia64/src/
Fix switch variable.
433
6858 d 21 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
6858 d 22 h

IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.
431

IA-64 work.
Exclude external interrupt from universal_handler() scope.

Move src/ and include/ to generic.

/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.
415
6874 d 5 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
6875 d 9 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
6875 d 19 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
6876 d 9 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.
403
6882 d 22 h
jermar
/SPARTAN/trunk/arch/
Small improvement in pte_t type definition.
402
6883 d 7 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.

mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.
Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
