Gleb, Paolo, here is a set of patches containing the floating interrupt controller and the async page fault patches on top of them. (It took a bit longer than expected) Several changes since v4 of the async patches mostly to make life migration possible: - Please have a look at patch 5. This one is new: We need to a way to let all workers finish to inject the completion interrupt. Otherwise guest processes will stall forever. (there is no wake all in the exisiting guest interface) - pfault is moved into flic. Reason is simple: The completion interrupts are floating, therefore we must serialize the flushing of pfault and creation of the completion interrupts (which are floating) with migrating all floating interrupts. - prepare pfault context for migration - bugfixes Everything else should look similar to what you already know. Changes since v3 of flic - new device number - no anonymous union - fixed sparse warning - get rid of KVM_S390_INT_MAX, which was a leftover from an earlier version This is what Alex approved (with known todos/cleanups for future patches) Let me know if you still have some concerns, otherwise, feel free to pull git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git tags/flic_pfault Christian Dominik Dingel (5): KVM: s390: Add FAULT_FLAG_RETRY_NOWAIT for guest fault KVM: async_pf: Provide additional direct page notification KVM: async_pf: Allow to wait for outstanding work KVM: async_pf: Async page fault support on s390 KVM: async_pf: Exploit one reg interface for pfault Jens Freimann (2): KVM: s390: add and extend interrupt information data structs KVM: s390: add floating irq controller Documentation/virtual/kvm/devices/s390_flic.txt | 36 +++ arch/s390/include/asm/kvm_host.h | 57 ++-- arch/s390/include/asm/pgtable.h | 2 + arch/s390/include/asm/processor.h | 1 + arch/s390/include/uapi/asm/kvm.h | 11 + arch/s390/kvm/Kconfig | 2 + arch/s390/kvm/Makefile | 2 +- arch/s390/kvm/diag.c | 84 ++++++ arch/s390/kvm/interrupt.c | 364 ++++++++++++++++++++---- arch/s390/kvm/kvm-s390.c | 134 ++++++++- arch/s390/kvm/kvm-s390.h | 4 + arch/s390/kvm/sigp.c | 7 + arch/s390/kvm/trace.h | 46 +++ arch/s390/mm/fault.c | 26 +- arch/x86/kvm/mmu.c | 2 +- arch/x86/kvm/x86.c | 8 +- include/linux/kvm_host.h | 5 +- include/uapi/linux/kvm.h | 66 +++++ virt/kvm/Kconfig | 4 + virt/kvm/async_pf.c | 28 +- virt/kvm/kvm_main.c | 5 + 21 files changed, 782 insertions(+), 112 deletions(-) create mode 100644 Documentation/virtual/kvm/devices/s390_flic.txt -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
