Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.

paging_start counting fix on ia64

ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
919
6737 d 4 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
6739 d 6 h
jermar
/kernel/trunk/arch/ia64/src/
ia64 work.
Support switch from userspace register stack in heavyweight handler.
915

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

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
6741 d 1 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.)

/kernel/trunk/
ELF framework for all archs. SPARC V9 not tested to compile.
906
6743 d 17 h
palkovsky
/kernel/trunk/
Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared
904

jermar
/kernel/trunk/arch/ia64/src/mm/
ia64 fix in page.c
== (comparison) was used istead of = (assignment).
903
6743 d 23 h
jermar
/kernel/trunk/arch/ia64/
ia64 work.
Add code needed for running multiple address spaces and location of kernel stack
after switch from userspace.
902

ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.
Fix generic hash table to properly initialize lists.
Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.
901
6745 d 6 h
jermar
/kernel/trunk/arch/
ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.
