As part of the meson build, we can record the dependencies for each component as we process it, logging them to a file. This file can be used as input to a number of other scripts and tools, for example, to graph the dependencies, or to allow higher-level build-config tools to automatically enable component requirements, etc.
The first patch of this set separates dependencies inside meson into optional or mandatory. The second patch of this set generates the basic dependency tree. The third patch does some processing of that dependency tree to identify cases where dependencies are being unnecessarily specified. Reducing these makes it easier to have readable dependency graphs in future, without affecting the build. The following 4 patches are based on the output of the second patch, and greatly cut down the number of direct dependency links between components. Even with the cut-down dependencies, the full dependency graph is nigh-unreadable, so the final patch adds a new script to generate dependency tree subgraphs, creating dot files for e.g. the dependencies of a particular component, or a component class such as mempool drivers. v6: - Fix build for common/qat - Rebase - Rename some patch headings to avoid check git log warnings v4 -> v5: - Improve optional dependency handling by making it (mostly) automatic - Fix CI issue from accidentally changing testpmd binary filename - Explicitly encode display name vs binary name information in the graph - Reduce some more dependencies - Update all scripts to handle new graph output format v3 -> v4: - Update to latest main v2 -> v3: - Split dependencies into optional and mandatory - Fixup graph scripts to read and generate graphs that encode optional dependencies into the graph - Python version fixes to avoid using features not available in minimum supported Python version -
