From 047a9d9eaa254616a44ae9edebf611ab16453922 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 21 Jun 2021 23:01:07 +0200 Subject: [PATCH] package/bmap-tools: enable host package bmaptool allows to drastically reduce the amount of data to transfer when writing to an SD card. Example with a 544 MiB sdcard.img: $ bmaptool create sdcard.img > sdcard.bmap $ gzip sdcard.img $ bmaptool copy sdcard.img.gz /dev/sdc bmaptool: info: discovered bmap file 'sdcard.bmap' bmaptool: info: block map format version 2.0 bmaptool: info: 139265 blocks of size 4096 (544.0 MiB), mapped 23918 blocks (93.4 MiB or 17.2%) bmaptool: info: copying image 'sdcard.img.gz' to block device '/dev/sdc' using bmap file 'sdcard.bmap' bmaptool: info: 100% copied bmaptool: info: synchronizing '/dev/sdc' bmaptool: info: copying time: 7.7s, copying speed 12.1 MiB/sec So it means that instead of writing 544 MiB, only 93.4 MiB had to be written. In terms of implementation details, compared to the target bmap-tools package, there are fewer "selects" that are needed because: - The dependency on setuptools is not needed, because the package uses the setuptools SETUP_TYPE, so host-python-setuptools is already a build dependency. - host-python and host-python3 are always built with Expat XML support.
