isoimage-isohybrid: don't include cpio in cpio image

2018-09-20T12:41:31+00:00

Because the find | cpio processes execute in parallel connected via the pipe, and the cpio outputs in the same dir find searches for source files, the cpio will be included in itself partially, depending on how fast the build machine creates the cpio file before cpio gobbles it up. This bloats the ISO image, though compression reduces the .iso file size, once the kernel decompresses the cpio image and boots it live, it uses up to double the RAM memory. Fix this by creating the initrd.cpio file directly inside cr_workdir. (From OE-Core rev: 7a7b29f5f1392f4f87af4f20cda99c66b4789fde) Signed-off-by: Ioan-Adrian Ratiu Signed-off-by: Richard Purdie

wic: Introduce the --use-label partition parameter

2018-09-13T06:42:28+00:00

We can use this parameter to make the wic use the label to name a partition in /etc/fstab. (From OE-Core rev: 51638edaa00befaed58e2def255d46ae44d9234f) Signed-off-by: Kevin Hao Reviewed-by: Tom Rini Signed-off-by: Richard Purdie

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

build.py: add clean option to 'devtool build' command

2018-09-10T11:13:06+00:00

Add -c (--clean) optiont to 'devtool build' command so that users could easily clean things up when using devtool. I encountered a problem about do_prepare_recipe_sysroot failure when using `devtool build' command and I found myself in a situation where I either have to use `bitbake' command to clean things up or use `rm' to remove the directories under ${WORKDIR}. So add a clean option as it would be helpful when users want to clean things up to prepare an environment for a clean build.

isoimage-isohybrid: Fix variable names

2018-08-29T09:42:48+00:00

initrd.cpio is created in initrd_dir, not in cr_workdir. Gzip will let initrd.cpio uncompressed if the path is not found. Also, grub_image variable doesn't exist, grub_src_image should be used instead.

isoimage-isohybrid: Fix creating initrd.cpio

2018-08-29T09:42:48+00:00

Only bsdcpio works with numbers for option -R to specify user:group, while GNU cpio doesn't. Debian use GNU cpio so without this change, you cannot create ISO images without installing bsdcpio.

wic: bootimg-partition: Add support to create the u-boot boot config file

2018-08-15T20:45:58+00:00

By leveraging the distro boot command feature in the u-boot, we can compose the corresponding extlinux.conf when creating the wic image, and let u-boot boot the kernel automatically. For more detail about the u-boot distro boot command feature, please see doc/README.distro in u-boot source files.

wic: bootimg-partition: Add do_configure_partition() method

2018-08-15T20:45:58+00:00

We want to add some u-boot specific config file. Before doing this, we need know what files will be installed into this partition. So move the codes about parsing the IMAGE_BOOT_FILES into do_configure_partition(). No function change.
