Hi. The patch I send before was too large so that it was dropped from the maling list. I'm sending again with smaller size. This patch set is the xen paravirtualization of hand written assenbly code. And I expect that much clean up is necessary before merge. We really need the feed back before starting actual clean up as Eddie already said before. Eddie discussed how to clean up and suggested

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

This patch set is intended for the next merge window. They are just enhancements of the already merged patches or ia64 porting from x86 paravirt techniques and that their quality is enough for merge. This patch set is for binary patch optimization for paravirt_ops. The binary patch optimization is important on native case because the paravirt_ops overhead can be reduced by converting indirect

This patch set is for binary patch optimization for paravirt_ops. The binary patch optimization is important on native case because the paravirt_ops overhead can be reduced by converting indirect call into in-place execution or direct call. The first patch imports helper functions which themselves doesn't interesting things. The second patch replaces the indirect function calls with a

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

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. 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. This patchset does the followings. - Some preparation work. Mainly importing header files to

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. 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 with Xen hypervisor. - Add some helper functions which is necessary to
