linux编译驱动之 make modules SUBDIRS

补充：make modules SUBDIRS=指定编译那个目录下的Makefile

今天在编译linux kernel的时候发现make menuconfig中配置成模式的驱动模块没有加入编译之,下面命令编译内核的：

make uImage

通过查看kernel的makefile发些了一些蛛丝马迹，现在将工作笔记记录如下：在linux kernel下运行终端，输入如下命令查看kernel编译相关的一些信息

make help 

Cleaning targets:
  clean           - Remove most generated files but keep the config and
                    enough build support to build external modules
  mrproper        - Remove all generated files + config + various backup files

                    (default: $(INSTALL_MOD_PATH)/lib/firmware)
  dir/            - Build all files in dir and below
  dir/file.[oisS] - Build specified target only
  dir/file.lst    - Build specified mixed source/assembly target only
                    (requires a recent binutils and recent build (System.map))
  dir/file.ko     - Build module including final link
  modules_prepare - Set up for building external modules
  tags/TAGS       - Generate tags file for editors
  cscope          - Generate cscope index
  gtags           - Generate GNU GLOBAL index
  kernelrelease   - Output the release version string
  kernelversion   - Output the version stored in Makefile
  headers_install - Install sanitised kernel headers to INSTALL_HDR_PATH
                    (default: /home/book/workspace/kernel/linux-3.4.2_jz2440/usr)


Static analysers
  checkstack      - Generate a list of stack hogs
  namespacecheck  - Name space analysis on compiled kernel
  versioncheck    - Sanity check on version.h usage
  includecheck    - Check for duplicate included header files
  export_report   - List the usages of all exported symbols
  headers_check   - Sanity check on exported headers
  headerdep       - Detect inclusion cycles in headers
  coccicheck      - Check with Coccinelle.


Kernel packaging:
  rpm-pkg             - Build both source and binary RPM kernel packages
  binrpm-pkg          - Build only the binary kernel package
  deb-pkg             - Build the kernel as a deb package
  tar-pkg             - Build the kernel as an uncompressed tarball
  targz-pkg           - Build the kernel as a gzip compressed tarball
  tarbz2-pkg          - Build the kernel as a bzip2 compressed tarball
  tarxz-pkg           - Build the kernel as a xz compressed tarball
  perf-tar-src-pkg    - Build perf-3.4.2.tar source tarball
  perf-targz-src-pkg  - Build perf-3.4.2.tar.gz source tarball
  perf-tarbz2-src-pkg - Build perf-3.4.2.tar.bz2 source tarball
  perf-tarxz-src-pkg  - Build perf-3.4.2.tar.xz source tarball


Documentation targets:
 Linux kernel internal documentation in different formats:
  htmldocs        - HTML
  pdfdocs         - PDF
  psdocs          - Postscript
  xmldocs         - XML DocBook

Architecture specific targets (arm):
* zImage        - Compressed kernel image (arch/arm/boot/zImage)
  Image         - Uncompressed kernel image (arch/arm/boot/Image)
* xipImage      - XIP kernel image, if configured (arch/arm/boot/xipImage)
  uImage        - U-Boot wrapped zImage
  bootpImage    - Combined zImage and initial RAM disk

发现并没有把make menuconfig中配置成模式的驱动模块没有加入编译，分析才发现还得执行如下命令就OK了。

make modules

相关的*.ko驱动模块就在kernel目录下!
