This series introduces the capability to synchronously exit the guest and prevent it from being re-entered. This modality will be used by IRQ forwarding series when changing the state of the IRQ. Former pause flag used when starting the vcpu in KVM_ARM_VCPU_POWER_OFF state, in PSCI calls and in KVM_SET_MP_STATE ioctl is renamed into power_off. A new pause flag is introduced. Both now are checked in kvm_arch_vcpu_runnable and in the VCPU_RUN critical section, before entering the vcpu. Best Regards Eric History: v1 -> v2: - check pause, power_off and in kvm_arch_vcpu_runnable - check power_off in vcpu_run critcal section before guest entry - correct compil issue in first patch reported by Andrew - rename vcpu_pause into vcpu_sleep RFC -> PATCH v1: - originally part of [RFC 00/17] ARM IRQ forward control based on IRQ bypass manager (https://lkml.org/lkml/2015/7/2/268) and isolated in this series. - added __maybe_unused following Marc's advice Eric Auger (4): KVM: arm/arm64: rename pause into power_off KVM: arm/arm64: check power_off in kvm_arch_vcpu_runnable KVM: arm/arm64: check power_off in critical section before VCPU run KVM: arm/arm64: implement kvm_arm_[halt,resume]_guest arch/arm/include/asm/kvm_host.h | 5 +++- arch/arm/kvm/arm.c | 53 ++++++++++++++++++++++++++++++--------- arch/arm/kvm/psci.c | 10 ++++---- arch/arm64/include/asm/kvm_host.h | 3 +++ 4 files changed, 53 insertions(+), 18 deletions(-) -- 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
