Support for __SYSCALL4.
Fix user stack initial address.

/kernel/trunk/
Nicer ia32 interrupt handlers and structures holding interrupted context data.

jermar
/kernel/trunk/
Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
938
6676 d 18 h
jermar
/kernel/trunk/
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.

Userspace is now working.
There is an unrelated show stopper, however.
919
6679 d 23 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.

- 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.

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
6683 d 20 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.)
910
6683 d 22 h
bondari
/kernel/trunk/
ELF framework for all archs. SPARC V9 not tested to compile.
903
6686 d 18 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
6687 d 23 h
jermar
/kernel/trunk/
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
6688 d 1 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.
900
6688 d 18 h
jermar
/kernel/trunk/arch/ia64/

Proper TLB fault handlers' headers and prototypes.
PFN 0 needs no longer be marked unavailable to frame allocator.
899
6688 d 19 h
jermar
/kernel/trunk/arch/
ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.

Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile.
792

/kernel/trunk/
Page hash table architectures now use generic hash table to manage
mappings.
763
6714 d 21 h
jermar
/kernel/trunk/
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
756
6716 d 12 h
jermar
/kernel/trunk/
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
753
6717 d 19 h
jermar

in a clean way.
