939 6621 d 0 h palkovsky /kernel/trunk/contrib/conf/ Fix msim configuration.  
938 6621 d 0 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6621 d 1 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
934 6621 d 1 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
932 6621 d 2 h palkovsky /kernel/trunk/generic/src/console/ Allow using direct address as parameter.  
931 6621 d 2 h palkovsky /kernel/trunk/generic/src/console/ Allow direct address specification.  
930 6621 d 4 h decky /kernel/trunk/contrib/conf/ preliminary Simics 3.0 configuration for Simics  
929 6621 d 4 h palkovsky /kernel/trunk/ Restrict itanium test to itanium.  
928 6621 d 5 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
927 6621 d 7 h decky /kernel/trunk/contrib/conf/ Simics 3.0 IA32/AMD64 component configuration  
925 6621 d 8 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
924 6621 d 10 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
923 6621 d 18 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
922 6623 d 20 h jermar /kernel/trunk/genarch/src/mm/ Fix generic page hash table to align down page addresses.
This was the ia64 userspace show stopper.		  
921 6624 d 1 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6624 d 6 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 6626 d 7 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6626 d 8 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 6627 d 22 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 6628 d 2 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.)
