   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
