Provide a description of the purpose of codman and some examples of how to use it. Series-to: concept Cover-letter: codman: Add a new source-code analysis tool Add a new tool called 'codman' (code manager) for analysing source code usage in U-Boot builds. This tool determines which files and lines of code are actually compiled based on the build configuration. The tool provides three analysis methods: - unifdef: Static preprocessor analysis (default) - DWARF: Debug information from compiled code (-w) - (experimental) LSP: Language server analysis using clangd (-l) Codman supports: - File-level analysis: which files are compiled vs unused - Line-level analysis: which lines are active vs removed by preprocessor - Kconfig-impact analysis with -a/--adjust option - Various output formats: stats, directories, detail, summary Since there is quite a lot of processing involved, Codman uses parallel processing where possible. This tool is admittedly not quite up to my normal code quality, but it has been an interesting experiment in using Claude to create something from scratch. The unifdef part of the tool benefits from some patches I created for that tool: - O(1) algorithm for symbol lookup, instead of O(n) - faster! - support for IS_ENABLED(), CONFIG_IS_ENABLED() Please get in touch if you would like the patches. This series also includes a minor improvement to buildman and a tidy-up of the tout library to reduce code duplication. END Signed-off-by: Simon Glass <simon.glass@canonical.com> Series-links: 1:65
This patch series adds support for ZFS listing and load to u-boot. To Enable zfs ls and load commands, modify the board specific config file with #define CONFIG_CMD_ZFS Steps to test: 1. After applying the patch, zfs specific commands can be seen in the boot loader prompt using UBOOT #help zfsload- load binary file from a ZFS file system zfsls - list files in a directory (default /) 2. To list the files in zfs pool, device or partition, execute zfsls <interface> <dev[:part]> [POOL/@/dir/file] For example: UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/ 3. To read and load a file from an ZFS formatted partition to RAM, execute zfsload <interface> <dev[:part]> [addr] [filename] [bytes] For example: UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
