As a first step it implements functionality to retrieve and inject interrupts for the purpose of migration and for hardening the reset code by allowing user space to explicitly remove all pending floating interrupts. PFAULT patches will also use this device for enabling/disabling pfault, therefore the pfault patch series will be reworked to use this device. * Patch 1 adds a new data structure to hold interrupt information. The current one (struct kvm_s390_interrupt) does not allow to inject all kinds of interrupts, e.g. some data for program interrupts and machine check interruptions were missing. * Patch 2 adds a kvm_device which supports getting/setting currently pending floating interrupts as well as deleting all currently pending interrupts Jens Freimann (2): KVM: s390: add and extend interrupt information data structs KVM: s390: add floating irq controller arch/s390/include/asm/kvm_host.h | 45 +---- arch/s390/include/uapi/asm/kvm.h | 5 + arch/s390/kvm/interrupt.c | 383 ++++++++++++++++++++++++++------------- arch/s390/kvm/kvm-s390.c | 1 + arch/s390/kvm/priv.c | 22 +-- arch/s390/kvm/sigp.c | 14 +- include/linux/kvm_host.h | 1 + include/uapi/linux/kvm.h | 63 +++++++ virt/kvm/kvm_main.c | 3 + 9 files changed, 348 insertions(+), 189 deletions(-) -- 1.8.2.3
