1053 6637 d 3 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1044 6637 d 7 h jermar /kernel/trunk/ Page table locking.  
1039 6637 d 7 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1023 6638 d 1 h vana /kernel/trunk/ Itanium FPU active context switch  
993 6639 d 0 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.		  
979 6639 d 6 h vana /kernel/trunk/arch/ia64/ Itanium FPU context save/restore  
962 6639 d 22 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Support for __SYSCALL4.
Fix user stack initial address.		  
958 6640 d 0 h 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.		  
947 6640 d 9 h vana /kernel/trunk/ Better purge page selection.  
945 6640 d 22 h vana /kernel/trunk/arch/ia64/  
944 6640 d 23 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
938 6641 d 1 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6641 d 2 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
928 6641 d 6 h vana /kernel/trunk/ Itanium tlb_invalidate_all

921 6644 d 2 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6644 d 7 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 6646 d 9 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6646 d 10 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.
