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 would be better to discuss with the Eddie's patch. - I implemented The basic portion of domU pv_ops. They may need the interface refinement. Probably Eddie has his own opinion. - This time I dropped the patches which hasn't been pv_ops'fied yet because they aren't changed from the last post. You can also get the full source from http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/ branch: xen-ia64-2008mar06 The patchset are organized as follows - xen arch portability. Generalizes x86 xen patches for ia64 support. - some preliminary patches. Make kernel paravirtualization friendly. - introduce pv_ops and the definitions for native. - basic helper functions for xen ia64 support. - introduce the pv_ops instance for xen/ia64. TODO: - discuss and define intrinsic paravirtualization abi. - discuss pv_ops. - more pv_ops for domU - mca/sal call - timer - gate page - fsys - support save/restore/live migration - more clean ups - remove unnecessary if (is_running_on_xen()). - Free xen_ivt areas somehow. No waste kernel space From Keith Owens idea. Probably after defining ABI because this is just optimization. - dom0 consider after finishing domU/ia64 merge. 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: arch/ia64/Kconfig | 72 +++ arch/ia64/kernel/Makefile | 30 +- arch/ia64/kernel/acpi.c | 4 + arch/ia64/kernel/asm-offsets.c | 25 + arch/ia64/kernel/entry.S | 568 +------------------ arch/ia64/kernel/head.S | 6 + arch/ia64/kernel/inst_native.h | 183 ++++++ arch/ia64/kernel/inst_paravirt.h | 28 + arch/ia64/kernel/iosapic.c | 43 +- arch/ia64/kernel/irq_ia64.c | 21 +- arch/ia64/kernel/ivt.S | 153 +++--- arch/ia64/kernel/minstate.h | 10 +- arch/ia64/kernel/module.c | 32 + arch/ia64/kernel/pal.S | 5 +- arch/ia64/kernel/paravirt.c | 94 +++ arch/ia64/kernel/paravirt_alt.c | 118 ++++ arch/ia64/kernel/paravirt_core.c | 201 +++++++ arch/ia64/kernel/paravirt_entry.c | 99 ++++ arch/ia64/kernel/paravirt_nop.c | 49 ++ arch/ia64/kernel/paravirtentry.S | 37 ++ arch/ia64/kernel/setup.c | 14 + arch/ia64/kernel/smpboot.c | 2 + arch/ia64/kernel/switch_leave.S | 603 +++++++++++++++++++ arch/ia64/kernel/vmlinux.lds.S | 35 ++ arch/ia64/xen/Makefile | 9 + arch/ia64/xen/hypercall.S | 141 +++++ arch/ia64/xen/hypervisor.c | 235 ++++++++ arch/ia64/xen/inst_xen.h | 503 ++++++++++++++++ arch/ia64/xen/irq_xen.c | 435 ++++++++++++++ arch/ia64/xen/irq_xen.h | 8 + arch/ia64/xen/machvec.c | 4 + arch/ia64/xen/paravirt_xen.c | 242 ++++++++ arch/ia64/xen/privops_asm.S | 221 +++++++ arch/ia64/xen/privops_c.c | 279 +++++++++ arch/ia64/xen/util.c | 101 ++++ arch/ia64/xen/xcom_asm.S | 27 + arch/ia64/xen/xcom_hcall.c | 458 +++++++++++++++ arch/ia64/xen/xen_pv_ops.c | 319 ++++++++++ arch/ia64/xen/xencomm.c | 108 ++++ arch/ia64/xen/xenivt.S | 59 ++ arch/ia64/{kernel/minstate.h => xen/xenminstate.h} | 96 +--- arch/ia64/xen/xenpal.S | 76 +++ arch/ia64/xen/xensetup.S | 60 ++ arch/x86/xen/Makefile | 4 +- arch/x86/xen/grant-table.c | 91 +++ arch/x86/xen/xen-ops.h | 2 +- drivers/xen/Makefile | 3 +- {arch/x86 => drivers}/xen/events.c | 33 +- {arch/x86 => drivers}/xen/features.c | 0 drivers/xen/grant-table.c | 37 +-- drivers/xen/xenbus/xenbus_client.c | 6 +- drivers/xen/xencomm.c | 232 ++++++++ include/asm-ia64/gcc_intrin.h | 58 +- include/asm-ia64/hw_irq.h | 24 +- include/asm-ia64/intel_intrin.h | 64 +- include/asm-ia64/intrinsics.h | 12 + include/asm-ia64/iosapic.h | 18 +- include/asm-ia64/irq.h | 33 ++ include/asm-ia64/machvec.h | 2 + include/asm-ia64/machvec_xen.h | 22 + include/asm-ia64/meminit.h | 3 +- include/asm-ia64/mmu_context.h | 6 +- include/asm-ia64/module.h | 6 + include/asm-ia64/page.h | 8 + include/asm-ia64/paravirt.h | 284 +++++++++ include/asm-ia64/paravirt_alt.h | 82 +++ include/asm-ia64/paravirt_core.h | 54 ++ include/asm-ia64/paravirt_entry.h | 62 ++ include/asm-ia64/paravirt_nop.h | 46 ++ include/asm-ia64/privop.h | 67 +++ include/asm-ia64/privop_paravirt.h | 587 +++++++++++++++++++ include/asm-ia64/sync_bitops.h | 59 ++ include/asm-ia64/system.h | 4 +- include/asm-ia64/xen/hypercall.h | 426 ++++++++++++++ include/asm-ia64/xen/hypervisor.h | 249 ++++++++ include/asm-ia64/xen/interface.h | 585 +++++++++++++++++++ include/asm-ia64/xen/page.h | 41 ++ include/asm-ia64/xen/privop.h | 609 ++++++++++++++++++++ include/asm-ia64/xen/xcom_hcall.h | 55 ++ include/asm-ia64/xen/xencomm.h | 33 ++ include/asm-x86/xen/hypervisor.h | 10 + include/asm-x86/xen/interface.h | 24 + include/{ => asm-x86}/xen/page.h | 0 include/xen/events.h | 1 + include/xen/grant_table.h | 6 + include/xen/interface/callback.h | 119 ++++ include/xen/interface/grant_table.h | 11 +- include/xen/interface/vcpu.h | 5 + include/xen/interface/xen.h | 22 +- include/xen/interface/xencomm.h | 41 ++ include/xen/page.h | 181 +------ include/xen/xen-ops.h | 6 + include/xen/xencomm.h | 77 +++ 93 files changed, 9174 insertions(+), 1049 deletions(-) _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel
