Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was already merged to linux ia64 test branch. This patch is for linux ia64 test branch. 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 utilize xen arch generic portion. - Next implements the xen instance of pv_ops introducing pv_info, pv_init_ops, pv_cpu_ops and its assembler counter part, pv_iosapic_ops, pv_irq_ops and, pv_time_ops step by step. - Introduce xen machine vector to describe xen platform. By using machine vector, xen domU implementation can be simplified. - Lastly update Kconfig to allow paravirtualization support and xen domU support to compile. 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-2008june10-xen-ia64 For the status of this patch series http://wiki.xensource.com/xenwiki/XenIA64/UpstreamMerge At this phase, we don't address the following issues. Those will be addressed after the first merge. - optimization by binary patch In fact, we had the patch to do that, but we intentionally dropped for patch size/readability/cleanness. - freeing the unused pages, i.e. pages for unused ivt.S. - complete save/restore support Changes from take 6: - rebased to linux ia64 test branch - xen bsw_1 simplification. - add documentation. Documentation/ia64/xen.txt - preliminary support for save/restore. - network fix. NET_SKB_PAD. Changes from take 5: - rebased to Linux 2.6.26-rc3 - fix ivt.S paravirtualization. One instruction was wrongly paravirtualized. It wasn't revealed with Xen HVM domain so far, but with real hw - multi entry point support. - revised changelog to add CCs. Changes from take 4: - fix synch bit ops definitions to prevent accidental namespace clashes. - rebased and fixed breakages due to the upstream change. Changes from take 3: - split the patch set into pv_op part and xen domU part. - many clean ups. - introduced pv_ops: pv_cpu_ops and pv_time_ops. Changes from take 2: - many clean ups following to comments. - clean up:assembly instruction macro. - introduced pv_ops: pv_info, pv_init_ops, pv_iosapic_ops, pv_irq_ops. Changes from take 1: Single IVT source code. compile multitimes using assembler macros. thanks, Diffstat: Documentation/ia64/xen.txt | 183 ++++++++++++++ arch/ia64/Kconfig | 32 +++ arch/ia64/Makefile | 2 + arch/ia64/kernel/acpi.c | 5 + arch/ia64/kernel/asm-offsets.c | 38 +++ arch/ia64/kernel/nr-irqs.c | 1 + arch/ia64/kernel/process.c | 1 - arch/ia64/xen/Kconfig | 26 ++ arch/ia64/xen/Makefile | 22 ++ arch/ia64/xen/grant-table.c | 155 ++++++++++++ arch/ia64/xen/hypercall.S | 91 +++++++ arch/ia64/xen/hypervisor.c | 96 ++++++++ arch/ia64/xen/irq_xen.c | 422 +++++++++++++++++++++++++++++++++ arch/ia64/xen/irq_xen.h | 34 +++ arch/ia64/xen/machvec.c | 4 + arch/ia64/xen/suspend.c | 59 +++++ arch/ia64/xen/time.c | 198 +++++++++++++++ arch/ia64/xen/time.h | 24 ++ arch/ia64/xen/xcom_hcall.c | 441 ++++++++++++++++++++++++++++++++++ arch/ia64/xen/xen_pv_ops.c | 364 ++++++++++++++++++++++++++++ arch/ia64/xen/xencomm.c | 106 ++++++++ arch/ia64/xen/xenivt.S | 52 ++++ arch/ia64/xen/xensetup.S | 83 +++++++ include/asm-ia64/machvec.h | 2 + include/asm-ia64/machvec_xen.h | 22 ++ include/asm-ia64/meminit.h | 3 +- include/asm-ia64/sync_bitops.h | 57 +++++ include/asm-ia64/timex.h | 2 + include/asm-ia64/xen/events.h | 50 ++++ include/asm-ia64/xen/grant_table.h | 29 +++ include/asm-ia64/xen/hypercall.h | 265 +++++++++++++++++++++ include/asm-ia64/xen/hypervisor.h | 72 ++++++ include/asm-ia64/xen/inst.h | 461 ++++++++++++++++++++++++++++++++++++ include/asm-ia64/xen/interface.h | 320 +++++++++++++++++++++++++ include/asm-ia64/xen/irq.h | 44 ++++ include/asm-ia64/xen/minstate.h | 134 +++++++++++ include/asm-ia64/xen/page.h | 65 +++++ include/asm-ia64/xen/privop.h | 129 ++++++++++ include/asm-ia64/xen/xcom_hcall.h | 51 ++++ include/asm-ia64/xen/xencomm.h | 34 +++ 40 files changed, 4177 insertions(+), 2 deletions(-) -- 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
