wic: bootimg-efi: Support + symbol in filenames

2025-04-28T15:18:53+00:00

Allow the '+' symbol as a valid character in filenames listed in the IMAGE_EFI_BOOT_FILES variable. The '+' symbol might be used to support boot counting for boot entries, as described in the UAPI Boot Loader Specification [1]: The boot counting data is stored in the name of the boot loader entry. A boot loader entry file name may contain a plus (+) followed by a number. This may optionally be followed by a minus (-) followed by a second number. The dot (.) and file name suffix (conf or efi) must immediately follow. Boot counting is enabled for entries which match this pattern. Example: IMAGE_EFI_BOOT_FILES:append = " entry.conf;loader/entries/entry+3.conf" [1] https://uapi-group.org/specifications/specs/boot_loader_specification/#boot-counting (From OE-Core rev: 081fa0ebb33dbbfd0f6e8239690261c0a9dcdb2c) Signed-off-by: Igor Opaniuk Signed-off-by: Richard Purdie (cherry picked from commit 3f25822281eb9423ff86105eaebb0bed48663648) Signed-off-by: Jose Quaresma Signed-off-by: Steve Sakoman

wic: bootimg-efi: fix error handling

2024-08-01T13:08:09+00:00

If we check for empty variables, it does not make sense to print their content in case they are empty. Additionally, the error message in the 'kernel' check attempted to print the wrong variable ('target') which was not even defined, yet. Also, raising WicError doesn't require an extra newline.

wic: bootimg-partition allow to set var to get boot files

2024-03-26T17:10:51+00:00

This is a generic functionality that takes a set of files and create a boot parition based on IMAGE_BOOT_FILES var, allow to sepcify the variable name so a BSP plugin can extend this and re-use the functionality.

wic: implement reproducible Disk GUID

2024-02-08T10:53:13+00:00

GPT based disks have a disk guid apart from the 32-bit disk identifier. This commit implements reproducible disk guid by using SOURCE_DATE_EPOCH (if available) value as a random seed (From OE-Core rev: 150e079589e207fe174d2dceb40cd8f3d3972c5a) Signed-off-by: Adithya Balakumar Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

wic: extend empty plugin with options to write zeros to partiton

2023-12-06T22:55:49+00:00

Adds features to explicitly write zeros to the start of the partition. This is useful to overwrite old content like filesystem signatures which may be re-recognized otherwise. The new features can be enabled with '--soucreparams="[fill|size=[S|s|K|k|M|G]][,][bs=[S|s|K|k|M|G]]"' Conflicting or missing options throw errors. The features are: - fill Fill the entire partition with zeros. Requires '--fixed-size' option to be set. - size=[S|s|K|k|M|G] Set the first N bytes of the partition to zero. Default unit is 'K'. - bs=[S|s|K|k|M|G] Write at most N bytes at a time during source file creation. Defaults to '1M'. Default unit is 'K'.

wic: bootimg-efi: Make kernel image installation configurable

2023-12-04T11:23:37+00:00

The issue with installing the kernel image to both rootfs and boot partition is that some systems rely on the kernel image in rootfs and not in the boot partition. This leads to duplication of the kernel image, which can cause unnecessary storage usage. This patch provides a solution to the problem by adding a new parameter "install-kernel-into-boot-dir" to the wic kickstart file. If this parameter is set to 'true', the plugin will install the kernel image to the boot partition. If the parameter is set to 'false', the plugin will skip installing the kernel image, avoiding duplication.

wic: Add gpt-hybrid partition layout

2023-09-02T10:47:50+00:00

Add support for formatting a disk with a hybrid MBR & GPT partition scheme. In this scheme, the primary partitioning method is GPT, but a valid MBR header is also written than can point to a subset of the GPT partitions on the disk (any partitions marked with the `--mbr` flag will be included in this MBR). The primary purpose of this method is to allow for SoCs that can only find a bootloader in an MBR partition to use GPT once the bootloader is running. As an example, older versions of the Raspberry Pi firmware can only parse MBR partitions to find a kernel (or other bootloader like u-boot), but once those have booted GPT partitions can be used. In addition to the partitions annotated with the `--mbr`, a "protective" GPT partition of type 0xEE is added, as the existence of such a partition is the indication to tooling that this a hybrid MBR and that the GPT partition table should be parsed instead.
