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.

wic: allow bitbake variables in kickstarter files

2019-01-14T11:35:56+00:00

image_types_wic.bbclass has a mechanism for doing variable substitution on .wks files by simply letting the input file be called .wks.in. However, that doesn't allow using variables in files included via the include directive. This is unfortunate, because lacking either the ability to include other files or variable substitution leads to fragile and error-prone duplication between kickstarter files and recipes/configuration files used for various boards. This adds (somewhat naive) support for variable substitution in all files parsed by wic. The user should add all required variables to WICVARS to get them exported appropriately.

wic: squashfs does support partition uuid.

2018-09-11T08:05:35+00:00

wic allows the user to create disk image and reference each created partitions via its partition UUID. squashfs does not support filesystem UUID but it does offer support for partition UUID. $ lsblk -o NAME,FSTYPE,UUID,PARTUUID NAME FSTYPE UUID PARTUUID sda |-sda1 vfat 6078-ACD0 95aa4ffb-741d-4d99-adf6-0358bc890046 |-sda2 squashfs 7d46da2d-29cc-4d5a-9e39-d0381c4abb0c |-sda3 squashfs d4a3e24e-410a-4f2c-8ad5-8f8321de177b |-sda4 ext4 d72ec529-78e4-4cd3-b39b-781b6b1cb47c f3edc990-f4f6-4536-9587-44dae4ceb99f `-sda5 ext4 a0b265aa-e935-40b8-9c6b-e9e58ad3890f 6e72ebaa-29ed-41cd-844c-3f76976cf41d Modifying this constrain allows a user to create squashfs-based rootfs and boot from them with such kernel argument 'root=PARTUUID=7d46da2d-29cc-4d5a-9e39-d0381c4abb0c' Fixes: 2fbdcf4e59c8 ("wic: kparser.py: Check for SquashFS and use-uuid") (From OE-Core rev: a8787bbfdf088b0ef9feb8e6b4230b743bb4086f) Signed-off-by: Emmanuel Roullit Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

wic: Introduce --fsuuid and have --use-uuid make use of UUID too

2017-12-18T18:03:58+00:00

First, allow for wic to be given a filesystem UUID to be used when creating a filesystem. When not provided, wic will generate the UUID to be used. Next, when --use-uuid is passed, we update the fstab to mount things via UUID (and if not found, then use PARTUUID) as UUID is more portable.

wic: add 'part-name' argument for naming GPT partitions

2017-11-07T13:25:31+00:00

The WIC's 'part' can now give a name for GPT partition in WKS file. It's similar to '--label', but is naming partintions instead file systems. It's required by some bootloaders to partitions have specified names.
