+# @ECLASS-VARIABLE: K_ROGKERNEL_NAME

+# The kernel name used by the ebuild, it should be the ending ${PN} part

+K_ROGKERNEL_NAME="${K_ROGKERNEL_NAME:-${PN/${PN/-*}-}}"
+
+# @ECLASS-VARIABLE: K_ROGKERNEL_SELF_TARBALL_NAME
+# @DESCRIPTION:
+# If the main kernel sources tarball is generated in-house and available
+# on the "kogaion" mirror, set this variable to the extension name (see example
+# below). This will disable ALL the extra/local patches (since they have to
+# be applied inside the tarball). Moreover, K_ROGKERNEL_NAME,
+# K_KERNEL_PATCH_VER will be ignored.
+# Example:
+# K_ROGKERNEL_SELF_TARBALL_NAME="kogaion"
+# This would generate:
+# SRC_URI="mirror://kogaion/sys-kernel/linux-${PV}+kogaion.tar.${K_TARBALL_EXT}"

+
+# @ECLASS-VARIABLE: K_ROGKERNEL_PATCH_UPSTREAM_TARBALL

+# creating complete kernel source tarballs. The default value is 0.
