# @GICCapability:
#
# The struct describes capability for a specific GIC (Generic
# Interrupt Controller) version.  These bits are not only decided by
# QEMU/KVM software version, but also decided by the hardware that the
# program is running upon.
#
# @version: version of GIC to be described.  Currently, only 2 and 3
#     are supported.
#
# @emulated: whether current QEMU/hardware supports emulated GIC
#     device in user space.
#
# @kernel: whether current QEMU/hardware supports hardware accelerated
#     GIC device in kernel.
#
# Since: 2.6
