wic: Add --include-path argument

2020-01-10T21:18:22+00:00

This option adds the contents of the given path to a partition built with the rootfs source plugin. The path is relative to the directory in which wic is running not the rootfs itself so use of an absolute path is recommended. This option is most useful when multiple copies of the rootfs are added to an image and it is required to add extra content to only one of these copies. This option only has an effect with the rootfs source plugin. (From OE-Core rev: d4cd27a9837426e809190548a83c6c7c76505114) Signed-off-by: Paul Barker Signed-off-by: Richard Purdie

wic: Using the right rootfs size during prepare_rootfs

2019-09-27T12:02:16+00:00

The commit 8e48b4d6c4 makes wic ignores IMAGE_ROOTFS_SIZE for rootfs size and makes it uses the computed one only. Re-add support for IMAGE_ROOTFS_SIZE variable and compute roots size only if the former is not defined. Moreover the size of a provided directory with --rootfs-dir="" in the .wks file should always be computed on the fly, else every partition will be constrained to be the same size as what ever value was in ROOTFS_SIZE.

wic: Make disk partition size consistently computed

2019-08-12T15:23:57+00:00

When using different root directories with a wks file wic is using the value from the original ROOTFS_SIZE which is not correct. Example: Number Start End Size File system Name Flags 1 20.5kB 318MB 318MB fat16 otaefi legacy_boot, msftdata 2 318MB 636MB 318MB ext4 otaboot 3 636MB 1709MB 1074MB ext4 otaroot 4 1709MB 2027MB 318MB ext4 otaboot_b 5 2027MB 3101MB 1074MB ext4 otaroot_b 6 3101MB 5249MB 2147MB ext4 fluxdata The partitions 1, 2, and 3 incorrectly inherit the size, instead of using a computed size. With the patch applied it is working properly: Number Start End Size File system Name Flags 1 20.5kB 14.5MB 14.5MB fat16 otaefi legacy_boot, msftdata 2 14.5MB 65.3MB 50.8MB ext4 otaboot 3 65.3MB 1139MB 1074MB ext4 otaroot 4 1139MB 1190MB 50.8MB ext4 otaboot_b 5 1190MB 2264MB 1074MB ext4 otaroot_b 6 2264MB 4411MB 2147MB ext4 fluxdata As for the removal of the bb.warn, if the size is not specified, it is not something to warn the end user about. Some of my default images make use of the head room + a computed directory size or while generating images.

wic: Add partition type for msdos partition tables

2019-08-12T15:23:57+00:00

In order to create a msdos partition table disk image that can auto expand after the image is copied to an SD card, wic needs the ability to have a primary partition as the last entry. The desired use case is to be able to create an A/B update partition image scheme with a /var volume that can be auto expanded to the remainder of the SD card at run time. The typical .wks file will look similar to the following: bootloader --ptable msdos part / --source rawcopy --sourceparams="file=u-boot.imx" \ --ondisk mmcblk --no-table --align 1 --size 1 part /boot --source bootimg-partition \ --ondisk mmcblk --fstype=vfat --label boot --active --align 4 --size 16 part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaboot --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaroot --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaboot_b --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaroot_b --align 4 --type logical part /var --source rawcopy --sourceparams="file=imx6_var.otaimg" \ --ondisk mmcblk --fstype=ext4 --label fluxdata --align 4 Without the patch applied, wic will generate an SD card image that looks like: Disk boot.img: 890940s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 2056s 48001s 45946s primary fat16 lba 2 48008s 132467s 84460s primary ext4 3 132472s 454467s 321996s primary ext4 4 454471s 890939s 436469s extended lba 5 454472s 538931s 84460s logical ext4 6 538936s 860931s 321996s logical ext4 7 860936s 890939s 30004s logical ext4 boot With the patch applied a primary partition can be created at the end of the image which can be expanded to fill the free space on the media where the image has been copied, which looks like: Disk boot.img: 890940s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 2056s 48001s 45946s primary fat16 lba 2 48007s 860931s 812925s extended lba 5 48008s 132467s 84460s logical ext4 6 132472s 454467s 321996s logical ext4 7 454472s 538931s 84460s logical ext4 8 538936s 860931s 321996s logical ext4 3 860936s 890939s 30004s primary ext4 boot (From OE-Core rev: 56add7cc547e0113cdf980579d1421b14cc233e5) Signed-off-by: Jason Wessel Signed-off-by: Richard Purdie

meta/lib+scripts: Convert to SPDX license headers

2019-05-09T15:31:55+00:00

This adds SPDX license headers in place of the wide assortment of things currently in our script headers. We default to GPL-2.0-only except for the oeqa code where it was clearly submitted and marked as MIT on the most part or some scripts which had the "or later" GPL versioning. The patch also drops other obsolete bits of file headers where they were encoountered such as editor modelines, obsolete maintainer information or the phrase "All rights reserved" which is now obsolete and not required in copyright headers (in this case its actually confusing for licensing as all rights were not reserved). More work is needed for OE-Core but this takes care of the bulk of the scripts and meta/lib directories. The top level LICENSE files are tweaked to match the new structure and the SPDX naming.

Revert "wic: Set a miniumum FAT16 volume size."

2019-04-26T09:09:08+00:00

This reverts commit f7dfb4d43247d3c13a4e0a3853007d63b9512b83. FAT16 volumes do not have a minimum size of 8250 blocks (== slightly over 4MB). Exhibit A: floppy disks. The original commit message suggests this was a workaround for a bug in parted - in which case we should fix it there, or use the wic `--fixed-size` option to pass down an enforced minimum from a more context-aware point in the callstack.

wic: Fix partition files UIDs on multi rootfs images

2018-05-22T12:13:32+00:00
