Hi Tony. I'd like to merge those patches and the other xen domU optimization patches at the next merge window. i.e. for 2.6.29. What do you think? I think that they are just enhancements of the already merged patches or ia64 porting from x86 paravirt techniques and that their quality is enough for merge. Although people want some twist, I believe they would be minor. thanks, On Tue, Nov 25, 2008 at 10:03:50PM +0900, Isaku Yamahata wrote: > 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 special > call written in gcc extended inline asm and introduces native methods. > The third patch introduces binary patch for kernel modules. > The forth patch suppress false positive warnings which were caused by > the previous patches. > The last patch implements xen methods. > > > For convenience the working full source is available from > http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/ > branch: ia64-pv-ops-2008nov25-xen-ia64-optimized-domu-binary-patch > > For the status of this patch series > http://wiki.xensource.com/xenwiki/XenIA64/UpstreamMerge > > thanks, > > Diffstat: > arch/ia64/include/asm/intrinsics.h | 6 +- > arch/ia64/include/asm/module.h | 6 + > arch/ia64/include/asm/paravirt.h | 8 + > arch/ia64/include/asm/paravirt_patch.h | 143 +++++++ > arch/ia64/include/asm/paravirt_privop.h | 347 ++++++++++++++++- > arch/ia64/include/asm/xen/privop.h | 4 + > arch/ia64/kernel/Makefile | 3 +- > arch/ia64/kernel/efi.c | 1 + > arch/ia64/kernel/module.c | 32 ++ > arch/ia64/kernel/paravirt.c | 520 ++++++++++++++++++++++++- > arch/ia64/kernel/paravirt_patch.c | 509 +++++++++++++++++++++++ > arch/ia64/kernel/paravirtentry.S | 101 ++++- > arch/ia64/kernel/setup.c | 1 + > arch/ia64/kernel/vmlinux.lds.S | 24 ++ > arch/ia64/kvm/vtlb.c | 2 + > arch/ia64/xen/hypercall.S | 2 + > arch/ia64/xen/xen_pv_ops.c | 667 +++++++++++++++++++++++++++++++ > 17 files changed, 2351 insertions(+), 25 deletions(-) -- yamahata -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
