955 6637 d 16 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6637 d 20 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
951 6637 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
947 6638 d 2 h vana /kernel/trunk/ Better purge page selection.  
945 6638 d 15 h vana /kernel/trunk/arch/ia64/  
944 6638 d 15 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
941 6638 d 17 h palkovsky /kernel/trunk/ Fixed mips elf loading.  
940 6638 d 17 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6638 d 18 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6638 d 18 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
934 6638 d 19 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
928 6638 d 23 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
925 6639 d 2 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
924 6639 d 3 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
923 6639 d 11 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
921 6641 d 18 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6641 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.		  
916 6644 d 1 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6644 d 2 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 6645 d 15 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.
