955 6682 d 4 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6682 d 7 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
951 6682 d 8 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
947 6682 d 13 h vana /kernel/trunk/ Better purge page selection.  
945 6683 d 2 h vana /kernel/trunk/arch/ia64/  
944 6683 d 3 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
941 6683 d 4 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6683 d 5 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6683 d 5 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6683 d 6 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
934 6683 d 6 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
928 6683 d 10 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
925 6683 d 13 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
924 6683 d 15 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
923 6683 d 23 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
921 6686 d 6 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6686 d 11 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 6688 d 12 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6688 d 13 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 6690 d 3 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.
