Support setting the distributor and cpu interface base addresses in the
VM physical address space through the KVM_{SET,GET}_DEVICE_ATTR API
in addition to the ARM specific API.
This has the added benefit of being able to share more code in user
space and do things in a uniform manner.
Also deprecate the older API at the same time, but backwards
compatibility will be maintained.

ARM Virtual Generic Interrupt Controller (VGIC)
|
|
===============================================
|
|
|
|
Device types supported:
|
|
KVM_DEV_TYPE_ARM_VGIC_V2 ARM Generic Interrupt Controller v2.0
|
|
|
|
Only one VGIC instance may be instantiated through either this API or the
|
|
legacy KVM_CREATE_IRQCHIP api. The created VGIC will act as the VM interrupt
|
|
controller, requiring emulated user-space devices to inject interrupts to the
|
|
VGIC instead of directly to CPUs.
|
|
|
|
Groups:
|
|
KVM_DEV_ARM_VGIC_GRP_ADDR
|
|
Attributes:
|
|
KVM_VGIC_V2_ADDR_TYPE_DIST (rw, 64-bit)
|
|
Base address in the guest physical address space of the GIC distributor
|
|
register mappings.
|
|
|
|
KVM_VGIC_V2_ADDR_TYPE_CPU (rw, 64-bit)
|
|
Base address in the guest physical address space of the GIC virtual cpu
|
|
interface register mappings.
