bitbake linux-name 执行各个task的过程

以下是在fsl-release-bsp/imx6solo2/tmp/work/imx6solosabresd-poky-linux-gnueabi/linux-imx/4.1.15-r0/temp目录下面的log.task_order文件内容。其实就是bitbake linux-imx的过程


do_fetch (8359): log.do_fetch.8359
do_unpack (8441): log.do_unpack.8441
do_patch (5650): log.do_patch.5650
do_copy_defconfig (27693): log.do_copy_defconfig.27693
do_configure (27788): log.do_configure.27788
do_compile (31731): log.do_compile.31731
do_shared_workdir (20614): log.do_shared_workdir.20614
do_compile_kernelmodules (16664): log.do_compile_kernelmodules.16664
do_uboot_mkimage (3088): log.do_uboot_mkimage.3088
do_strip (9837): log.do_strip.9837
do_sizecheck (10052): log.do_sizecheck.10052
do_install (10208): log.do_install.10208
do_package (7880): log.do_package.7880
do_packagedata (10268): log.do_packagedata.10268
do_populate_sysroot (25948): log.do_populate_sysroot.25948
do_bundle_initramfs (26152): log.do_bundle_initramfs.26152
do_deploy (26174): log.do_deploy.26174
do_package_write_rpm (460): log.do_package_write_rpm.460
do_populate_lic (10276): log.do_populate_lic.10276
do_package_qa (21158): log.do_package_qa.21158




从上面可以获得共有20个任务，他们的执行脚本具体在下面四个目录下面的文件中：
poky/meta/classes/base.bbclass
poky/meta/classes/kernel.bbclass


poky/meta/classes/kernel-yocto.bbclass


fsl-release-bsp/sources/meta-fsl-bsp-release/imx/meta-bsp/recipes-kernel/linux/linux-imx_4.1.15.bb




这些任务的顺序主要是由poky/meta/class目录下面的*.bbclass文件创建的，还有部分由bsp目录下面创建的。由bsp目录的.bb文件提供的任务有do_copy_defconfig
说明只有bsp提供的defconfig，并拷贝过去，其他的任务都在poky/meta/class文件目录下面的。




我用或者 或者命令来查找他们的执行顺序和脚本文件
任务一：do_fetch
./base.bbclass:116:addtask fetch




任务二：do_unpack
./base.bbclass:134:addtask unpack after do_fetch




任务三：do_patch
./patch.bbclass:184:addtask patch after do_unpack


任务四：do_copy_defconfig（注意不在class目录下面了）
./imx/meta-bsp/recipes-kernel/linux/linux-imx_4.1.15.bb:21:addtask copy_defconfig after do_unpack before do_configure




任务五：do_configure
./base.bbclass:262:addtask configure after do_patch
./kernel-yocto.bbclass:262:addtask kernel_configme before do_configure after do_patch


任务六：do_compile
./base.bbclass:280:addtask compile after do_configure


任务七：do_shared_workdir
./kernel.bbclass:256:addtask shared_workdir after do_compile before do_compile_kernelmodules




任务八：do_compile_kernelmodules
./kernel.bbclass:224:addtask compile_kernelmodules after do_compile before do_strip




任务九：do_uboot_mkimage
./kernel-uimage.bbclass:36:addtask uboot_mkimage before do_install after do_compile




任务十：do_strip
./kernel.bbclass:438:addtask do_strip before do_sizecheck after do_kernel_link_vmlinux




任务十一：do_sizecheck 
./kernel.bbclass:456:addtask sizecheck before do_install after do_strip




任务十二：do_install 
./base.bbclass:290:addtask install after do_compile




任务十三：do_package 
./package.bbclass:2042:addtask package after do_install


任务十四：do_packagedata

任务十六：do_bundle_initramfs 
./kernel.bbclass:193:addtask bundle_initramfs after do_install before do_deploy




任务十七：do_deploy 
./kernel.bbclass:496:addtask deploy after do_populate_sysroot




任务十八：do_package_write_rpm
