+# @ECLASS-VARIABLE: K_ARGKERNEL_NAME
+# @DESCRIPTION:
+# The kernel name used by the ebuild, it should be the ending ${PN} part
+# for example, of linux-argent it is "${PN/${PN/-*}-}" (argent)
+K_ARGKERNEL_NAME="${K_ARGKERNEL_NAME:-${PN/${PN/-*}-}}"
+
+# @ECLASS-VARIABLE: K_ARGKERNEL_SELF_TARBALL_NAME
+# @DESCRIPTION:
+# If the main kernel sources tarball is generated in-house and available
+# on the "argent" 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_ARGKERNEL_NAME,
+# K_KERNEL_PATCH_VER will be ignored.
+# Example:
+#   K_ARGKERNEL_SELF_TARBALL_NAME="argent"
+#   This would generate:
+#   SRC_URI="mirror://argent/sys-kernel/linux-${PV}+argent.tar.${K_TARBALL_EXT}"
+K_ARGKERNEL_SELF_TARBALL_NAME="${K_ARGKERNEL_SELF_TARBALL_NAME:-}"
+
+# @ECLASS-VARIABLE: K_ARGKERNEL_PATCH_UPSTREAM_TARBALL
+# @DESCRIPTION:
+# If set to 1, the ebuild will fetch the upstream kernel tarball and
+# apply the RogentOS patch against it. This strategy avoids the need of
+# creating complete kernel source tarballs. The default value is 0.
