2024-04-22lpdump: Add info about super partitionSandeep Dhavale
Currently we do not print info about super partition in lpdump. Let's add it so we can get to know super's size and used size. Available space can be inferred from these two.

2024-01-17lpmake: unlink before writingSteven Moreland
If Cuttlefish was starting using an image that was built earlier, the build used to write over this image. Now, we unlink the output first, so we don't break any existing programs which are using the outputs: Though, there are other reasons that CF may not work from multiple builds: > Requested resuming a previous session (the default behavior) but the base images have changed under the overlay, making the overlay incompatible. Wiping the overlay files. Anyway, you can see it works: Test: boot CF with a new image build with an existing version already running List of devices attached 0.0.0.0:6520 device 0.0.0.0:6521 device Bug: 179194264 Change-Id: Ie83c568915880e656c011eda474e2d42dfd1fa17

2023-04-17Merge "partition_tools: extend lpunpack for split partitions"David Anderson
2023-04-17partition_tools: extend lpunpack for split partitionsDaniel Köster
This is meant for retrofitted dynamic partitions where several super partitions are used. Until now lpunpack fails with the message "Split super devices are not supported." in this case. Extend lpunpack to support zero or more '-i' arguments with which additional super images may be referenced. Before running this new tool, do lpdump on the main super image file and examine the section 'Super partition layout' to get an idea which additional image files may be needed.

2023-02-08lpmake: Fix some issues in size calculation.David Anderson
When using "auto" for the super partition size, the size was computed totally wrong for small alignments. It doesn't show up in production since the default alignment is quite large (1MiB). Also, when specifing image files, the partition size is now automatically calculated if specified as 0. Bug: N/A Test: lpmake Change-Id: I8f3f3ff2d5f0b60163c17edc4bdba647fa1decc1

2021-04-01Add auto option to device sizeInseob Kim
Typically device size is determined first, and then lpmake checks if given partitions fit to the device or not. But it could be the case that one wants to minimize the super image size, like microdroid. This change adds "--device-size=auto" option to support minimized super image. If set, the device size will be the sum of partition sizes plus some spaces for metadata. Bug: 181107248 Test: boot microdroid Change-Id: I441f996de10df58bcfeb6f6ee637f15360d3b709

2019-04-25Add an lpunpack tool for extracting partitions from super.img.David Anderson
This tool performs the inverse of lpmake. It can extract partition images out of a prebuilt super.img. There are a few caveats: - lpunpack does not support retrofit/split images. - lpunpack does not support sparse super images. They must be unsparsed before using with lpunpack. - Partition names will be suffixed on A/B devices, meaning, vendor_a.img will contain vendor.img and vendor_b.img will be 0-length. Note that lpunpack will store output files with holes for zero blocks, as a space-saving measure.
