• kconfig_diff

  Compare the session's current values with another config file. A full .config lists every symbol that has a value, so a bool/tristate missing from it is n - that's the default. For a defconfig or a config fragment (only the interesting lines), pass fragment=True to compare just the symbols the file mentions.

• kconfig_load

  Parse a Kconfig tree (and optionally a .config) into a session named `name`. kconfig_path is the top-level Kconfig file; its directory becomes srctree. env supplies the variables the tree expands - Linux needs SRCARCH and ARCH (e.g. {"SRCARCH": "x86", "ARCH": "x86_64"}); Zephyr needs ZEPHYR_BASE and friends. Missing ones are named in the error. shell: "run" executes the tree's $(shell,...) compiler probes with a POSIX sh, as `make menuconfig` would. "dry" runs nothing (no compiler needed, works on Windows); compiler-feature symbols then read as absent. A Linux tree takes 10-40 s to parse; the…

• kconfig_save

  Write the current configuration. minimal=True writes a defconfig-style file with only the values that differ from defaults.

• kconfig_search

  Find symbols whose name, prompt or help text matches `query` (case-insensitive; a regex is accepted). Name matches rank first.

• kconfig_sessions

  List loaded sessions.

• kconfig_set

  Assign a value (y/m/n for bool/tristate; a number or string otherwise) as if in menuconfig, then report everything else that changed as a result. If the value doesn't stick (hidden prompt, unmet dependency, choice rules) it says so - use kconfig_why_not to see why.

• kconfig_symbol

  Everything about one symbol: type, prompt, current value and why, help text, where it's defined, its dependencies, and what selects/implies it.

• kconfig_unload

  Forget a loaded session.

• kconfig_what_selects

  Who forces this symbol on (select), who suggests it (imply), and what it selects/implies itself - with current values and locations.

• kconfig_why_not

  Explain why a symbol isn't (or can't be) at `value`, and how to fix it. Walks every unmet `depends on`, `visible if`, `if` block, choice and select/default condition with file:line, recursing into the symbols they name. Then searches for a minimal set of assignments and VERIFIES it by applying it to the tree - a fix is only shown if Kconfig agrees it works, along with its side effects. value: "y", "m", or "n" (why can't I turn it off?).
