wic: add 'none' fstype for custom image

2022-08-12T18:22:04+00:00

It's not possible to set the label (of gpt entry) normally when I want to use non-listed fstype as a rawcopy. Example) part ? --source rawcopy --ondisk mmcblk0 --label mypart --sourceparams file=mypart.raw To resolve this problem, this patch addes a 'none' fstype and ignore do_image_label on rawcopy (that actually set the partition label.)

wic: added fspassno parameter to partition

2022-05-16T22:19:18+00:00

The `fspassno` parameter allows to overwrite the value of the last column (`fs_passno`) in the /etc/fstab of the target root file system. This allows to have periodic file system checks.

wic: Add --no-fstab-update part option

2021-08-20T07:53:03+00:00

When embedding a rootfs image (e.g. 'rootfs-dir') as a partition we might want to keep the stock fstab for that image. In such a case, use this option to not update the fstab and use the stock one instead. This option allows you to specify which partitions get the fstab updated and which get the stock fstab. The option matches the argument you can pass to wic itself where the same action is performed but for all the partitions. Example: part /export --source rootfs --rootfs-dir=hockeycam-image --fstype=ext4 --label export --align 1024 --no-fstab-update part / --source rootfs --fstype=ext4 --label rootfs --align 1024 (From OE-Core rev: ab4c95af8ecd15dc136194ab761afae756db5803) Signed-off-by: Daniel Gomez Signed-off-by: Richard Purdie

Add support for erofs filesystems

2021-05-31T13:31:01+00:00

Since Linux 5.4 a new read-only filesystem is available, erofs. Compared to squashfs it offers much better read performance with and without compression enabled. It suppports two optional compressors, lz4 and lz4hc. >From the mkfs.erofs man page: EROFS is a new enhanced lightweight linux read-only filesystem with modern designs (eg. no buffer head, reduced metadata, inline xattrs/data, etc.) for scenarios which need high-performance read-only requirements, e.g. Android OS for smartphones and LIVECDs. It also provides fixed-sized output compression support, which improves storage density, keeps relatively higher compression ratios, which is more useful to achieve high performance for embedded devices with limited memory since it has unnoticable memory overhead and page cache thrashing. This commit adds support for three new filesystem targets: erofs: erofs without compression erofs-lz4: erofs with lz4 compresssion enabled erofs-lz4hc: erofs with lz4hc compression enabled (From OE-Core rev: 41dead1ff8ccc49e6cd6e6f5d41a59d164693e0d) Signed-off-by: Richard Weinberger Signed-off-by: Richard Purdie

wic/direct/kparser: ensure fsuuid for vfat and msdos align with format

2021-01-01T23:15:13+00:00

vfat/msdos filesystem should have fsuuid in format 0xYYYYYYYY where "0x" in front follow with 8 hexadecimal number in uppercase. In wic, when using custom fsuuid for vfat/msdos partition in wks, it is able to set the value in any length, with or without leading "0x". This can cause fsuuid missaligned when fstab updates, fstab expect exactly 10 character fsuuid for vfat/msdos partition and all in uppercase. if custom fsuuid for vfat/msdos is set, check the length and format, error if it exceed the format size. Amend it so it is align with format 0xYYYYYYYY. This is done before image create and fstab update to ensure the fsuuid are same in all followup process. if custom fsuuid length less than expected, fill in "0".

wic: Add 512 Byte alignment to --offset

2020-08-22T14:46:55+00:00

Allows the --offset argument to use the "s" or "S" suffix to specify that it is reporting the number of 512 byte sectors. This is required for some SoCs where the mask ROM looks for an item at a sector that isn't aligned to a 1KB boundary.

wic: Add --offset argument for partitions

2020-06-04T12:27:32+00:00

Add support for an --offset argument when defining a partition. Many SoCs require that boot partitions be located at specific offsets. Prior to this argument, most WKS files were using the --align attribute to specify the location of these fixed partitions but this is not ideal because in the event that the partition couldn't be placed in the specified location, wic would move it to the next sector with that alignment, often preventing the device from booting. Unlike the --align argument, wic will fail if a partition cannot be placed at the exact offset specified with --offset. Changes in V2: * Fixed a small typo that prevented test_fixed_size_error from passing (From OE-Core rev: 467f84e12b96bc977d57575023517dd6f8ef7f29) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

wic: root: Add an opt. destination on include-path

2020-04-26T13:00:50+00:00

Allow specifying an optional destination to include-path and make the option aware of permissions and owners. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --fstype=ext4 --include-path core-image-minimal-mtdutils export/ --include-path hello on the .wks file.

wic: Add --change-directory argument

2020-04-26T13:00:50+00:00

This option allows to specify which part of a rootfs is going to be included, the same way the -C argument on tar. Thanks to this option we can make sure the permissions and usernames on the target partition are respected, and also simplify the creation of splitted partitons, not neeting to invoke external vars or using .wks.in files.
