3# Makefile snippet to ${TOOL_MDSETIMAGE} file system images into kernels
4#
5
6#
7# Required variables:
8#	NETBSDSRCDIR	Top level of src tree (set by <bsd.own.mk>)
9#	MDSETTARGETS	List of images to ${TOOL_MDSETIMAGE} into kernels,
10#			containing one or more tuples of the form:
11#				KERNEL	IMAGE	FILENAME
12#
13#			The kernel is ${TOOL_MDSETIMAGE} with ${IMAGE},
14#			${STRIP}ped (after the symbols are stored in
15#			${FILENAME}.symbols.gz), and gzipped into
16#			${FILENAME}.gz.
17#
18#			If KERNEL does not contain a `/', use
19#			${KERNOBJDIR}/KERNEL/netbsd as the kernel.
20#
21#			If FILENAME is "-", use "netbsd-${KERNEL}" as
22#			the target name.  This may not be a sensible
23#			name if KERNEL contains a `/'.
24#
25# Optional variables:
26#	MDSET_RELEASEDIR		Where to install release kernels.
27#
28#	MDSET_NOGZIP			If defined, don't gzip any kernels.
29#
30#	MDSET_NOGZIP.${FILENAME}	If defined, don't gzip ${FILENAME}
31#
32#	MDSET_NOSTRIP			If defined, don't strip any kernels.
33#
34#	MDSET_NOSTRIP.${FILENAME}	If defined, don't strip ${FILENAME}
35#
36#	MDSET_NOSYMBOLS			If defined, don't generate *.symbols.gz
37#
38#	MDSET_NOSYMBOLS.${FILENAME}	If defined, don't generate
39#					${FILENAME}.symbols.gz
40#
41#	MDSET_POST			For each kernel,
42#					execute this after ${NM} / ${STRIP}.
43#					Kernel is available as "${.TARGET}"
44#
45#	MDSET_POST.${FILENAME}		For each kernel named ${FILENAME},
46#					execute this after ${NM} / ${STRIP}.
47#					Kernel is available as "${.TARGET}"
48#
49#	MDSET_SUFFIXES.${FILENAME}	List of extra install kernel suffixes
50#					and build commands to create from
51#					${FILENAME} after its created by
52#					${TOOL_MDSETIMAGE} ; ${NM} ; ${STRIP}:
53#						SUFFIX	COMMANDVAR
54#					"${.TARGET}" is "${FILENAME}.${SUFFIX}"
55#					COMMANDVAR is the name of the variable
56#					containing the command to build
57#					${.TARGET}.
58#
59# Variables modified by this:
60#	KERNELS			List of kernel .gz files to build
61#	KERNELSYMS		List of kernel .symbol.gz files to build
62#
