#
# Makefile snippet to ${TOOL_MDSETIMAGE} file system images into kernels
#
#
# Required variables:
# NETBSDSRCDIR Top level of src tree (set by <bsd.own.mk>)
# MDSETTARGETS List of images to ${TOOL_MDSETIMAGE} into kernels,
# containing one or more tuples of the form:
# KERNEL IMAGE FILENAME
#
# The kernel is ${TOOL_MDSETIMAGE} with ${IMAGE},
# ${STRIP}ped (after the symbols are stored in
# ${FILENAME}.symbols.gz), and gzipped into
# ${FILENAME}.gz.
#
# If KERNEL does not contain a `/', use
# ${KERNOBJDIR}/KERNEL/netbsd as the kernel.
#
# If FILENAME is "-", use "netbsd-${KERNEL}" as
# the target name. This may not be a sensible
# name if KERNEL contains a `/'.
#
# Optional variables:
# MDSET_RELEASEDIR Where to install release kernels.
#
# MDSET_NOGZIP If defined, don't gzip any kernels.
#
# MDSET_NOGZIP.${FILENAME} If defined, don't gzip ${FILENAME}
#
# MDSET_NOIMAGE.${FILENAME} If defined, don't add ${IMAGE} to
# ${FILENAME}
#
# MDSET_NOSTRIP If defined, don't strip any kernels.
#
# MDSET_NOSTRIP.${FILENAME} If defined, don't strip ${FILENAME}
#
# MDSET_NOSYMBOLS If defined, don't generate *.symbols.gz
#
# MDSET_NOSYMBOLS.${FILENAME} If defined, don't generate
# ${FILENAME}.symbols.gz
#
# MDSET_POST For each kernel,
# execute this after ${NM} / ${STRIP}.
# Kernel is available as "${.TARGET}"
#
# MDSET_POST.${FILENAME} For each kernel named ${FILENAME},
# execute this after ${NM} / ${STRIP}.
# Kernel is available as "${.TARGET}"
#
# MDSET_SUFFIXES.${FILENAME} List of extra install kernel suffixes
# and build commands to create from
# ${FILENAME} after its created by
# ${TOOL_MDSETIMAGE} ; ${NM} ; ${STRIP}:
# SUFFIX COMMANDVAR
# "${.TARGET}" is "${FILENAME}.${SUFFIX}"
# COMMANDVAR is the name of the variable
# containing the command to build
# ${.TARGET}.
#
# Variables modified by this:
# KERNELS List of kernel .gz files to build
# KERNELSYMS List of kernel .symbol.gz files to build
