It will be able to boot from both. + This is useful when managing PC fleet with some older machines + without EFI support. + + Note it is possible to create an image that can boot from both + legacy BIOS and EFI by defining two partitions : one with arg + --source bootimg-efi and another one with --source bootimg-pcbios. + However, this method has the obvious downside that it requires TWO + partitions to be created on the storage device. + Both partitions will also be marked as "bootable" which does not work on + most BIOS, has BIOS often uses the "bootable" flag to determine + what to boot. If you have such a BIOS, you need to manually remove the + "bootable" flag from the EFI partition for the drive to be bootable. + Having two partitions also seems to confuse wic : the content of + the first partition will be duplicated into the second, even though it + will not be used at all. + + Also, unlike "isoimage-isohybrid" that also does BIOS and EFI, this plugin + allows you to have more than only a single rootfs partitions and does + not turn the rootfs into an initramfs RAM image. + + This plugin is made to put everything into a single /boot partition so it + does not have the limitations listed above. + + The plugin is made so it does tries not to reimplement what's already + been done in other plugins; as such it imports "bootimg-pcbios" + and "bootimg-efi". + Plugin "bootimg-pcbios" is used to generate legacy BIOS boot. + Plugin "bootimg-efi" is used to generate the UEFI boot. Note that it + requires a --sourceparams argument to know which loader to use; refer + to "bootimg-efi" code/documentation for the list of loader. + + Imports are handled with "SourceFileLoader" from importlib as it is + otherwise very difficult to import module that has hyphen "-" in their + filename. + The SourcePlugin() methods used in the plugins (do_install_disk, + do_configure_partition, do_prepare_partition) are then called on both, + beginning by "bootimg-efi". + + Plugin options, such as "--sourceparams" can still be passed to a + plugin, as long they does not cause issue in the other plugin. + + Example wic configuration: + part /boot --source bootimg-biosplusefi --sourceparams="loader=grub-efi"\\ + --ondisk sda --label os_boot --active --align 1024 --use-uuid + """ + + name = 'bootimg-biosplusefi' + + __PCBIOS_MODULE_NAME = "bootimg-pcbios" + __EFI_MODULE_NAME = "bootimg-efi" + + __imgEFIObj = None + __imgBiosObj = None + + @classmethod + def __init__(cls): + """ + Constructor (init) + """ + + # XXX + # For some reasons, __init__ constructor is never called. + # Something to do with how pluginbase works? + cls.__instanciateSubClasses() + + @classmethod + def __instanciateSubClasses(cls): + """ + + """ + + # Import bootimg-pcbios (class name "BootimgPcbiosPlugin") + modulePath = os.path.join(os.path.dirname(os.path.realpath(__file__)), + cls.__PCBIOS_MODULE_NAME + ".py") + loader = SourceFileLoader(cls.__PCBIOS_MODULE_NAME, modulePath) + mod = types.ModuleType(loader.name) + loader.exec_module(mod) + cls.__imgBiosObj = mod.BootimgPcbiosPlugin() + + # Import bootimg-efi (class name "BootimgEFIPlugin") + modulePath = os.path.join(os.path.dirname(os.path.realpath(__file__)), + cls.__EFI_MODULE_NAME + ".py") + loader = SourceFileLoader(cls.__EFI_MODULE_NAME, modulePath) + mod = types.ModuleType(loader.name) + loader.exec_module(mod) + cls.__imgEFIObj = mod.BootimgEFIPlugin() + + @classmethod + def do_install_disk(cls, disk, disk_name, creator, workdir, oe_builddir, + bootimg_dir, kernel_dir, native_sysroot): + """ + Called after all partitions have been prepared and assembled into a + disk image. + """ + + if ( (not cls.__imgEFIObj) or (not cls.__imgBiosObj) ): + cls.__instanciateSubClasses() + + cls.__imgEFIObj.do_install_disk( + disk, + disk_name, + creator, + workdir, + oe_builddir, + bootimg_dir, + kernel_dir, + native_sysroot) + + cls.__imgBiosObj.do_install_disk( + disk, + disk_name, + creator, + workdir, + oe_builddir, + bootimg_dir, + kernel_dir, + native_sysroot) + + @classmethod + def do_configure_partition(cls, part, source_params, creator, cr_workdir, + oe_builddir, bootimg_dir, kernel_dir, + native_sysroot): + """ + Called before do_prepare_partition() + """ + + if ( (not cls.__imgEFIObj) or (not cls.__imgBiosObj) ): + cls.__instanciateSubClasses() + + cls.__imgEFIObj.do_configure_partition( + part, + source_params, + creator, + cr_workdir, + oe_builddir, + bootimg_dir, + kernel_dir, + native_sysroot) + + cls.__imgBiosObj.do_configure_partition( + part, + source_params, + creator, + cr_workdir, + oe_builddir, + bootimg_dir, + kernel_dir, + native_sysroot) + + @classmethod + def do_prepare_partition(cls, part, source_params, creator, cr_workdir, + oe_builddir, bootimg_dir, kernel_dir, + rootfs_dir, native_sysroot): + """ + Called to do the actual content population for a partition i.e. it + 'prepares' the partition to be incorporated into the image. + """ + + if ( (not cls.__imgEFIObj) or (not cls.__imgBiosObj) ): + cls.__instanciateSubClasses() + + cls.__imgEFIObj.do_prepare_partition( + part, + source_params, + creator, + cr_workdir, + oe_builddir, + bootimg_dir, + kernel_dir, + rootfs_dir, + native_sysroot) + + cls.__imgBiosObj.do_prepare_partition( + part, + source_params, + creator, + cr_workdir, + oe_builddir, + bootimg_dir, + kernel_dir, + rootfs_dir, + native_sysroot) diff --git a/poky/scripts/lib/wic/plugins/source/bootimg-efi.py b/poky/scripts/lib/wic/plugins/source/bootimg-efi.py index 5cc5c8a6b..2cfdc10ec 100644 --- a/poky/scripts/lib/wic/plugins/source/bootimg-efi.py +++ b/poky/scripts/lib/wic/plugins/source/bootimg-efi.py @@ -74,8 +74,10 @@ class BootimgEFIPlugin(SourcePlugin): grubefi_conf += "menuentry '%s'{\n" % (title if title else "boot") kernel = get_bitbake_var("KERNEL_IMAGETYPE") -
