# This recipe tracks the linux-yocto-dev repository as its upstream source.
# Since this tree is frequently updated, and periodically rebuilt, AUTOREV is
# used to track its contents.
#
# This recipe is just like other linux-yocto variants, with the only difference
# being that to avoid network access during initial parsing, static SRCREVs are
# provided and overridden if the preferred kernel provider is linux-yocto-dev.
#
# To enable this recipe, set PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-dev"
