Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Now all the comments so far have been addressed, but only a few exceptions. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops strategy is appropriate too. Later I'll post the patchset which implements xen domU based on ia64/pv_ops.

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository.

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

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it

This patchset is ia64/xen domU patch take 12. Tony, please commit those patches. They are ready to commit because all the issues which were pointed out had been addressed and got enough reviews. This patchset does the followings. - Some preparation work. Mainly importing header files to define related structures. - Then, define functions related to hypercall which is the way to communicate

Hi. This patchset is ia64/xen domU patch take 8 which was updated following Tony's review. (Thank you very much, Tony.) This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset is for linux ia64 test branch and depends on some patches for xen common part I'll send separately. To compile, the changesets in x86/xen
