bootimg: Use mcopy to construct the hddimg

2011-12-16T16:05:36+00:00

The initial directory support (-d) added to mkdosfs has proven to be incomplete and non-compliant with FAT. Rather than continue to maintain this feature and work around the various issues, we can use mcopy to construct the image. bootimg.bbclass already depends on mtools-native (although it may not have needed to previously). No new dependencies are introduced. The image created passes dosfsck cleanly. Remove the call to dosfsck. mcopy reported an error with the image we were creating: Total number of sectors (107574) not a multiple of sectors per track (32)! Add some logic to ensure the total sector count is an integral number of sectors per track, including forcing the logical sector size to 512 in the mkdosfs command. The du -bks arguments are contradictory, -b is equivalent to "--apparent-size --block-size=1" and -k is --block-size=1K. If reordered, -kbs will report the disk usage in bytes insteadk of 1k blocks. Eliminate the ambiguity by using: du --apparent-size -ks (From OE-Core rev: 92d2ea1a306354c6565a1b05b51b5719e481840f) Signed-off-by: Darren Hart CC: Nitin A. Kamble Signed-off-by: Richard Purdie

bootimg: Allow for EFI-only boot images

2011-11-30T22:18:08+00:00

Condition building PCBIOS legacy images on MACHINE_FEATURES containing "pcbios" or not containing "efi". This ensures existing BSPs will continue to get the old PCBIOS legacy-only images. New BSPs can add "efi", "pcbios", or both. The images created likewise support one or the other or both. EFI-only ISO images are untested.

bootimg: Add grub-efi support

2011-11-30T22:18:08+00:00

Create a new grub-efi.bbclass and integrate it into bootimg alongside the syslinux support. This new class uses the output from the grub-efi-native recipe. Thanks goes to Josef Ahmad for the original build_grub_cfg() routine. The EFI features are only added to the image if MACHINE_FEATURES contains "efi". The resulting images are therefor either legacy boot only (like they were originally) or legacy boot and EFI boot. A new "dummy.bbclass" was added to allow for the conditional include of grub-efi. This makes it so if efi support is not to be built in, we don't spend time building grub-efi-native just because the include adds the dependency. There is a bug in the mkdosfs tool from the dosfstools package which causes it to crash when the directory passed with the -d parameter contains sub-directories. An /EFI/BOOT directory is required for a proper EFI installation. Until it is fixed, we install to the top level directory for the hddimg.

bootimg: Pull syslinux specific bits into syslinux.bbclass

2011-11-30T22:18:08+00:00

Working towards a more generic bootimg.bbclass, pull out all syslinux specific bits and let syslinux.bbclass manage them directly. This introduces no functional changes to the images constructed and the behavior remains unchanged.

bootimg: Refactor build_hddimg and build_iso routines

2011-11-30T22:18:07+00:00

Separate the construction of the ISO image from that of the hddimg. This is part of the groundwork for creating a much more flexible live image builder. (From OE-Core rev: 2da25c7c6649757350782a939bcc7553c5c86570) Signed-off-by: Darren Hart Signed-off-by: Richard Purdie

bootimg: Create a valid boot sector for the iso image

2011-11-18T14:24:52+00:00

It's possible to create an "hybrid" iso image that you can both burn to a CD-Rom and dd to a USB key. isohybrid will create a valid boot sector for the USB key case.

bitbake: machine specific sysroots implementation

2011-01-25T12:25:46+00:00

This commit changes the sysroots path to be machine specific. Changes includes: 1) STAGING_DIR_TARGET and STRAGING_DIR_HOST points to machine specific paths. 2) task stamp files. Adding ${MACHINE} info into stamp files for do_populate_sysroots and do_package tasks. Add a BB_STAMPTASK_BLACKLIST to keep native, nativesdk, crosssdk, and cross-canadian stamp unchanged. 3) siteconfig path. Separate the site config path for different machines to avoid one machine adopting the cache file of another machine. 4) sstate. Add machine name to sstate manifest file. Change relocation code for sstate paths since sysroot is machine. Keep native, nativesdk, crosssdk, and cross-canadian unchanged. 5) toolchain scripts. Change the environment path to point to machine specific sysroots in toolchain scripts bbclass. 6) Relocate la files when populating to a different machine of the same architecture. 7) Exclude STAGING_DIR_TARGET and STAGING_DIR_HOST parameter from sstate siginfo since they contain ${MACHINE} information.
