Hi. Thank you for comments on asm code paravirtualization. Its direction is getting clear. Although it hasn't been finished yet, I'd like to start discussion on ia64 intrinsics paravirtualization. This patch set is just for discussion so that it is a subset of xen Linux/ia64 domU paravirtualization, not self complete. You can get the full patched tree by typing git clone
