Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners around the place. paravirt: add an "mm" argument to alloc_pt paravirt: add a hook for once the allocator is ready paravirt: increase IRQ limit paravirt: unstatic leave_mm paravirt: unstatic smp_store_cpu_info paravirt: make siblingmap functions visible paravirt: export __supported_pte_mask xen: Allocate and free vmalloc areas arch/i386/kernel/setup.c | 2 arch/i386/kernel/smp.c | 5 - arch/i386/kernel/smpboot.c | 8 - arch/i386/kernel/vsyscall-note.S | 28 +++++ arch/i386/mm/init.c | 1 include/asm-i386/mach-default/irq_vectors_limits.h | 2 include/asm-i386/mmu_context.h | 2 include/asm-i386/paravirt.h | 8 + include/asm-i386/setup.h | 4 include/asm-i386/smp.h | 5 + include/linux/vmalloc.h | 4 mm/vmalloc.c | 53 +++++++++++ 12 files changed, 114 insertions(+), 8 deletions(-) The rest of the series is the Xen implementation itself. This includes the core of Xen itself, plus the Xenbus virtual bus, and virtual console, disk and net drivers. The vast majority of it is new code, with a few changes to non-Xen files to: 1. Makefile/Kconfig build stuff 2. add a new ELF note to the VDSO to select a Xen-optimised libc 3. a chunk of new code in entry.S, to handle upcalls from Xen, which in turn need to jump into other entry.S labels 4. Define a proper label for PG_owner_priv_1 5. Define a major for the Xen virtual block device 6. Increate NR_IRQ to 224 when CONFIG_PARAVIRT is enabled, even if there's no IO APIC. xen: Add nosegneg capability to the vsyscall page notes xen: Add Xen interface header files xen: Core Xen implementation xen: Xen virtual mmu xen: xen event channels xen: xen time implementation xen: xen configuration xen: add pinned page flag xen: Complete pagetable pinning for Xen xen: ignore RW mapping of RO pages in pagetable_init xen: Account for time stolen by Xen xen: Implement xen_sched_clock xen: Xen SMP guest support xen: Add support for preemption xen: lazy-mmu operations xen: hack to prevent bad segment register reload xen: Use the hvc console infrastructure for Xen console xen: Add Xen grant table support xen: Add the Xenbus sysfs and virtual device hotplug driver. xen: Add Xen virtual block device driver. xen: Add the Xen virtual network device driver. xen: Xen machine operations xen: handle external requests for shutdown, reboot and sysrq xen: Place vcpu_info structure into per-cpu memory, if possible xen: Attempt to patch inline versions of common operations arch/i386/Kconfig | 2 arch/i386/Makefile | 3 arch/i386/kernel/asm-offsets.c | 7 arch/i386/kernel/entry.S | 71 arch/i386/kernel/head.S | 5 arch/i386/kernel/vmlinux.lds.S | 1 arch/i386/xen/Kconfig | 11 arch/i386/xen/Makefile | 4 arch/i386/xen/enlighten.c | 1134 +++++++++++++ arch/i386/xen/events.c | 588 +++++++ arch/i386/xen/features.c | 29 arch/i386/xen/manage.c | 143 + arch/i386/xen/mmu.c | 599 +++++++ arch/i386/xen/mmu.h | 60 arch/i386/xen/multicalls.c | 115 + arch/i386/xen/multicalls.h | 45 arch/i386/xen/setup.c | 93 + arch/i386/xen/smp.c | 405 ++++ arch/i386/xen/time.c | 585 +++++++ arch/i386/xen/xen-asm.S | 114 + arch/i386/xen/xen-head.S | 36 arch/i386/xen/xen-ops.h | 70 arch/x86_64/kernel/early_printk.c | 5 drivers/Makefile | 2 drivers/block/Kconfig | 8 drivers/block/Makefile | 1 drivers/block/xen-blkfront.c | 988 +++++++++++ drivers/char/Kconfig | 8 drivers/char/Makefile | 1 drivers/char/hvc_xen.c | 159 + drivers/net/Kconfig | 12 drivers/net/Makefile | 1 drivers/net/xen-netfront.c | 1995 ++++++++++++++++++++++++ drivers/xen/Makefile | 2 drivers/xen/grant-table.c | 582 +++++++ drivers/xen/xenbus/Makefile | 7 drivers/xen/xenbus/xenbus_client.c | 569 ++++++ drivers/xen/xenbus/xenbus_comms.c | 233 ++ drivers/xen/xenbus/xenbus_comms.h | 46 drivers/xen/xenbus/xenbus_probe.c | 935 +++++++++++ drivers/xen/xenbus/xenbus_probe.h | 74 drivers/xen/xenbus/xenbus_xs.c | 861 ++++++++++ include/asm-i386/irq.h | 1 include/asm-i386/xen/hypercall.h | 431 +++++ include/asm-i386/xen/hypervisor.h | 73 include/asm-i386/xen/interface.h | 187 ++ include/linux/major.h | 2 include/linux/page-flags.h | 5 include/xen/events.h | 48 include/xen/features.h | 23 include/xen/grant_table.h | 107 + include/xen/hvc-console.h | 6 include/xen/interface/elfnote.h | 133 + include/xen/interface/event_channel.h | 195 ++ include/xen/interface/features.h | 43 include/xen/interface/grant_table.h | 375 ++++ include/xen/interface/io/blkif.h | 94 + include/xen/interface/io/console.h | 23 include/xen/interface/io/netif.h | 156 + include/xen/interface/io/ring.h | 260 +++ include/xen/interface/io/xenbus.h | 42 include/xen/interface/io/xs_wire.h | 87 + include/xen/interface/memory.h | 145 + include/xen/interface/physdev.h | 145 + include/xen/interface/sched.h | 77 include/xen/interface/vcpu.h | 177 ++ include/xen/interface/version.h | 60 include/xen/interface/xen.h | 446 +++++ include/xen/page.h | 178 ++ include/xen/xenbus.h | 234 ++ 70 files changed, 14361 insertions(+), 1 deletion(-) -- _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
