4.38 KVM_GET_MP_STATE
Capability: KVM_CAP_MP_STATE
-Architectures: x86, s390
+Architectures: x86, s390, arm, arm64
Type: vcpu ioctl
Parameters: struct kvm_mp_state (out)
Returns: 0 on success; -1 on error
Possible values are:
- - KVM_MP_STATE_RUNNABLE: the vcpu is currently running [x86]
+ - KVM_MP_STATE_RUNNABLE: the vcpu is currently running [x86,arm/arm64]
- KVM_MP_STATE_UNINITIALIZED: the vcpu is an application processor (AP)
which has not yet received an INIT signal [x86]
- KVM_MP_STATE_INIT_RECEIVED: the vcpu has received an INIT signal, and is
is waiting for an interrupt [x86]
- KVM_MP_STATE_SIPI_RECEIVED: the vcpu has just received a SIPI (vector
accessible via KVM_GET_VCPU_EVENTS) [x86]
- - KVM_MP_STATE_STOPPED: the vcpu is stopped [s390]
+ - KVM_MP_STATE_STOPPED: the vcpu is stopped [s390,arm/arm64]
- KVM_MP_STATE_CHECK_STOP: the vcpu is in a special error state [s390]
- KVM_MP_STATE_OPERATING: the vcpu is operating (running or halted)
[s390]
in-kernel irqchip, the multiprocessing state must be maintained by userspace on
these architectures.
+For arm/arm64:
+
+The only states that are valid are KVM_MP_STATE_STOPPED and
+KVM_MP_STATE_RUNNABLE which reflect if the vcpu is paused or not.

4.75 KVM_IRQFD
Capability: KVM_CAP_IRQFD
-Architectures: x86 s390
+Architectures: x86 s390 arm arm64
Type: vm ioctl
Parameters: struct kvm_irqfd (in)
Returns: 0 on success, -1 on error
irqfd. The KVM_IRQFD_FLAG_RESAMPLE is only necessary on assignment
and need not be specified with KVM_IRQFD_FLAG_DEASSIGN.
+On ARM/ARM64, the gsi field in the kvm_irqfd struct specifies the Shared
+Peripheral Interrupt (SPI) index, such that the GIC interrupt ID is
+given by gsi + 32.
