 # PTP clock support
 #
-# The implementation of ptp_kvm on arm is one experimental feature,
-# you need to apply private patches to enable it on your host machine.
-# See https://github.com/kata-containers/packaging/pull/998 for detailed info.
-#
-# as ptp_kvm is under review in upstream and linux kernel in virtio-fs branch
-# will change with time, we need update the patch again and again. For now, we
-# disable ptp_kvm to wait for the stable kernel version of virtio-fs or ptp_kvm
-# accept by upstream.
