+======================
+Generic vcpu interface
+======================
+
+The virtual cpu "device" also accepts the ioctls KVM_SET_DEVICE_ATTR,
+KVM_GET_DEVICE_ATTR, and KVM_HAS_DEVICE_ATTR. The interface uses the same struct
+kvm_device_attr as other devices, but targets VCPU-wide settings and controls.
+
+The groups and attributes per virtual cpu, if any, are architecture specific.
+
+1. GROUP: KVM_ARM_VCPU_PMU_V3_CTRL
+==================================
+
+:Architectures: ARM64
+
+1.1. ATTRIBUTE: KVM_ARM_VCPU_PMU_V3_IRQ
+---------------------------------------
+
+:Parameters: in kvm_device_attr.addr the address for PMU overflow interrupt is a
+ pointer to an int
+
+Returns:
+
+ ======= ========================================================
+ -EBUSY The PMU overflow interrupt is already set
+ -ENXIO The overflow interrupt not set when attempting to get it
+ -ENODEV PMUv3 not supported
+ -EINVAL Invalid PMU overflow interrupt number supplied or
+ trying to set the IRQ number without using an in-kernel
+ irqchip.
+ ======= ========================================================
+
+A value describing the PMUv3 (Performance Monitor Unit v3) overflow interrupt
+number for this vcpu. This interrupt could be a PPI or SPI, but the interrupt
+type must be same for each vcpu. As a PPI, the interrupt number is the same for
+all vcpus, while as an SPI it must be a separate number per vcpu.
+
+1.2 ATTRIBUTE: KVM_ARM_VCPU_PMU_V3_INIT
+---------------------------------------
+
+:Parameters: no additional parameter in kvm_device_attr.addr
+
+Returns:
+
+ ======= ======================================================
+ -ENODEV PMUv3 not supported or GIC not initialized
+ -ENXIO PMUv3 not properly configured or in-kernel irqchip not
+ configured as required prior to calling this attribute
+ -EBUSY PMUv3 already initialized
+ ======= ======================================================
+
+Request the initialization of the PMUv3. If using the PMUv3 with an in-kernel
+virtual GIC implementation, this must be done after initializing the in-kernel
+irqchip.
+
+
+2. GROUP: KVM_ARM_VCPU_TIMER_CTRL
+=================================
+
+:Architectures: ARM,ARM64
+
+2.1. ATTRIBUTES: KVM_ARM_VCPU_TIMER_IRQ_VTIMER, KVM_ARM_VCPU_TIMER_IRQ_PTIMER
+-----------------------------------------------------------------------------
+
+:Parameters: in kvm_device_attr.addr the address for the timer interrupt is a
+ pointer to an int
+
+Returns:
+
+ ======= =================================
+ -EINVAL Invalid timer interrupt number
+ -EBUSY One or more VCPUs has already run
+ ======= =================================
+
+A value describing the architected timer interrupt number when connected to an
+in-kernel virtual GIC. These must be a PPI (16 <= intid < 32). Setting the
+attribute overrides the default values (see below).
+
+============================= ==========================================
+KVM_ARM_VCPU_TIMER_IRQ_VTIMER The EL1 virtual timer intid (default: 27)
+KVM_ARM_VCPU_TIMER_IRQ_PTIMER The EL1 physical timer intid (default: 30)
+============================= ==========================================
+
+Setting the same PPI for different timers will prevent the VCPUs from running.
+Setting the interrupt number on a VCPU configures all VCPUs created at that
+time to use the number provided for a given timer, overwriting any previously
+configured values on other VCPUs. Userspace should configure the interrupt
+numbers on at least one VCPU after creating all VCPUs and before running any
+VCPUs.
+
+3. GROUP: KVM_ARM_VCPU_PVTIME_CTRL
+==================================
+
+:Architectures: ARM64
+
+3.1 ATTRIBUTE: KVM_ARM_VCPU_PVTIME_IPA
+--------------------------------------
+
+:Parameters: 64-bit base address
+
+Returns:
+
+ ======= ======================================
+ -ENXIO Stolen time not implemented
+ -EEXIST Base address already set for this VCPU
+ -EINVAL Base address not 64 byte aligned
+ ======= ======================================
+
+Specifies the base address of the stolen time structure for this VCPU. The
+base address must be 64 byte aligned and exist within a valid guest memory
+region. See Documentation/virt/kvm/arm/pvtime.txt for more information
+including the layout of the stolen time structure.
