# @ECLASS-VARIABLE: K_NASPATCHES_VER
# @DESCRIPTION:
# The version of the sablink patches tarball(s) to apply.
# A value of "5" would apply 2.6.12-5 to my-sources-2.6.12.ebuild
# @ECLASS-VARIABLE: K_NASKERNEL_NAME
# @DESCRIPTION:
# The kernel name used by the ebuild, it should be the ending ${PN} part
# for example, of linux-sablink it is "${PN/${PN/-*}-}" (sablink)
K_NASKERNEL_NAME="${K_NASKERNEL_NAME:-${PN/${PN/-*}-}}"
# @ECLASS-VARIABLE: K_NASKERNEL_URI_CONFIG
# @DESCRIPTION:
# Set this either to "no" or "yes" depending on the location of the
# kernel config files. If they are inside FILESDIR (old location)
# leave this option set to "no", otherwise set this to "yes"
K_NASKERNEL_URI_CONFIG="${K_NASKERNEL_URI_CONFIG:-no}"
# @ECLASS-VARIABLE: K_NASKERNEL_SELF_TARBALL_NAME
# @DESCRIPTION:
# If the main kernel sources tarball is generated in-house and available
# on the "sablink" mirror, set this variable to the extension name (see example
# below). This will disable ALL the extra/local patches (since they have to
# be applied inside the tarball). Moreover, K_NASKERNEL_URI_CONFIG,
# K_NASPATCHES_VER, K_NASKERNEL_NAME, K_KERNEL_PATCH_VER will be ignored.
# Example:
# K_NASKERNEL_SELF_TARBALL_NAME="sablink"
# This would generate:
# SRC_URI="mirror://sablink/sys-kernel/linux-${PV}+sablink.tar.bz2"

# @TODO: deprecate and remove once 2.6.x kernels are retired
K_KERNEL_PATCH_VER="${K_KERNEL_PATCH_VER:-}"
# @ECLASS-VARIABLE: K_KERNEL_PATCH_HOTFIXES
# @DESCRIPTION:
# If there is the need to quickly apply patches to the kernel
# without bumping the kernel patch tarball (for eg. in case
# of just released security fixes), set this variable in your ebuild
# pointing to space separated list of patch paths.
K_KERNEL_PATCH_HOTFIXES="${K_KERNEL_PATCH_HOTFIXES:-}"
# @ECLASS-VARIABLE: K_KERNEL_DISABLE_PR_EXTRAVERSION
# @DESCRIPTION:
# Set this to "1" if you want to tell kernel-2 eclass to
# not use ${PR} in kernel EXTRAVERSION (K_NOUSEPR). Otherwise, set
# this to "0" to not set K_NOUSEPR at all.

# firmware pkgs.
K_KERNEL_SLOT_USEPVR="${K_KERNEL_SLOT_USEPVR:-0}"

# by linux-openvz and linux-vserver
K_WORKAROUND_SOURCES_COLLISION="${K_WORKAROUND_SOURCES_COLLISION:-}"
