/kernel/trunk/
Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.

Itanium FPU active context switch
993
6732 d 22 h
jermar
/kernel/trunk/arch/ia64/
Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.

Allowed userspace to include page.h.

ia64 work.
Support for __SYSCALL4.
Fix user stack initial address.

jermar
/kernel/trunk/
Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.

Added kernel IPC functionality.

Itanium tlb_invalidate_pages
940
6734 d 23 h
jermar
/kernel/trunk/
Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
938
6735 d 0 h
jermar
/kernel/trunk/
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.

Two frame stack (standard stack + RSE) on Itanium

Itanium tlb_invalidate_all

ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
919
6738 d 5 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.

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.

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
6742 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.)
