From: Kim Phillips <kim.phillips@xxxxxxxxxx> The KVM-VFIO device is used by the QEMU VFIO device. It is used to record the list of in-use VFIO groups so that KVM can manipulate them. Signed-off-by: Kim Phillips <kim.phillips@xxxxxxxxxx> Signed-off-by: Eric Auger <eric.auger@xxxxxxxxxx> --- - previously included in KVM-VFIO IRQ forward control v6 series. Rationale to put it aside is the unavailability of the kvm-vfio device causes produces a warning when launching the QEMU VFIO platform device that can puzzle some users (although not blocking): "Failed to create KVM VFIO device: No such device" --- arch/arm/kvm/Kconfig | 1 + arch/arm/kvm/Makefile | 2 +- arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/Makefile | 2 +- 4 files changed, 4 insertions(+), 2 deletions(-) diff --git a/arch/arm/kvm/Kconfig b/arch/arm/kvm/Kconfig index f1f79d1..bfb915d 100644 --- a/arch/arm/kvm/Kconfig +++ b/arch/arm/kvm/Kconfig @@ -28,6 +28,7 @@ config KVM select KVM_GENERIC_DIRTYLOG_READ_PROTECT select SRCU select MMU_NOTIFIER + select KVM_VFIO select HAVE_KVM_EVENTFD select HAVE_KVM_IRQFD depends on ARM_VIRT_EXT && ARM_LPAE && ARM_ARCH_TIMER diff --git a/arch/arm/kvm/Makefile b/arch/arm/kvm/Makefile index 139e46c..c5eef02c 100644 --- a/arch/arm/kvm/Makefile +++ b/arch/arm/kvm/Makefile @@ -15,7 +15,7 @@ AFLAGS_init.o := -Wa,-march=armv7-a$(plus_virt) AFLAGS_interrupts.o := -Wa,-march=armv7-a$(plus_virt) KVM := ../../../virt/kvm -kvm-arm-y = $(KVM)/kvm_main.o $(KVM)/coalesced_mmio.o $(KVM)/eventfd.o +kvm-arm-y = $(KVM)/kvm_main.o $(KVM)/coalesced_mmio.o $(KVM)/eventfd.o $(KVM)/vfio.o obj-y += kvm-arm.o init.o interrupts.o obj-y += arm.o handle_exit.o guest.o mmu.o emulate.o reset.o diff --git a/arch/arm64/kvm/Kconfig b/arch/arm64/kvm/Kconfig index 5105e29..bfffe8f 100644 --- a/arch/arm64/kvm/Kconfig +++ b/arch/arm64/kvm/Kconfig @@ -28,6 +28,7 @@ config KVM select KVM_ARM_HOST select KVM_GENERIC_DIRTYLOG_READ_PROTECT select SRCU + select KVM_VFIO select HAVE_KVM_EVENTFD select HAVE_KVM_IRQFD ---help--- diff --git a/arch/arm64/kvm/Makefile b/arch/arm64/kvm/Makefile index d5904f8..f90f4aa 100644 --- a/arch/arm64/kvm/Makefile +++ b/arch/arm64/kvm/Makefile @@ -11,7 +11,7 @@ ARM=../../../arch/arm/kvm obj-$(CONFIG_KVM_ARM_HOST) += kvm.o -kvm-$(CONFIG_KVM_ARM_HOST) += $(KVM)/kvm_main.o $(KVM)/coalesced_mmio.o $(KVM)/eventfd.o +kvm-$(CONFIG_KVM_ARM_HOST) += $(KVM)/kvm_main.o $(KVM)/coalesced_mmio.o $(KVM)/eventfd.o $(KVM)/vfio.o kvm-$(CONFIG_KVM_ARM_HOST) += $(ARM)/arm.o $(ARM)/mmu.o $(ARM)/mmio.o kvm-$(CONFIG_KVM_ARM_HOST) += $(ARM)/psci.o $(ARM)/perf.o -- 1.9.1 -- 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
