wic: rawcopy: Add support for packed images

2022-02-16T09:46:29+00:00

Add support for packed images to wic rawcopy handler do minimize disk usage in deploy directory and reuse of packed images between wic and swupdate. Add `unpack` to sourceparams to unpack an bz2, gz and xz archives. Example: part / --source rawcopy --sourceparams="file=core-image-minimal-qemu.ext4.gz,unpack" (From OE-Core rev: 4c97d25791389ece041565981ba3207ce9949a1a) Signed-off-by: Stefan Herbrechtsmeier 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: fix images build in parallel

2020-01-19T13:24:39+00:00

OE wic plugins create temporary file with the index of the line tmp file name. This causes race in case several builds run in time. If source_params['file'] is an absolute path, the cr_workdir prefix is not applied by os.path.join(). So instead it writes to a ".1" file next to the original image - this is outside the WORKDIR and at risk of collision.

wic/rawcopy: Support files in sub-directories

2019-10-19T22:18:33+00:00

If the source file is located in a subdirectory of DEPLOY_DIR rawcopy will currently fail in sparse_copy function on open(dst_fname, 'wb'), as the parent directory for destination file does not exist. This patch helps to avoid that by recursively creating parent directories. (From OE-Core rev: 073c435644091c2801e45c6d02afa917de575082) Signed-off-by: Eugene Smirnov 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: support filesystem label for rawcopy

2017-12-10T22:45:19+00:00

The '--label' argument should work for '--source rawcopy' as it does for '--source rootfs', so add a method in RawCopyPlugin to update the label on the temporary filesystem images.

wic: remove empty plugin methods

2017-03-23T13:19:49+00:00

Removed do_install_disk and do_configure_partition methods from bootimage-partition, fsimage and rawcopy plugins as they're empy and not used. [YOCTO #10618] (From OE-Core rev: d58c8ef2836418056f776a9586e0bb0d33afb788) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: use kernel_dir instead of bootimg_dir

2017-03-23T13:19:49+00:00

bootimg_dir is usually set to the value of STAGING_DATADIR and kernel_dir - to the value of DEPLOY_DIR_IMAGE, so usage of kernel_dir is more logical in bootimg-efi, bootimg-partition and rawcopy plugins. Replaced usage of bootimg_dir to kernel_dir in 3 above mentioned plugins that use DEPLOY_DIR_IMAGE as a default artifact location.
