| H A D | Kconfig | 90e5b38a26529391da2d851a9cc5eb9de2ec35ca Fri Dec 19 18:13:18 UTC 2025 Ihor Solodrai <ihor.solodrai@linux.dev> kbuild: Sync kconfig when PAHOLE_VERSION changes
This patch implements kconfig re-sync when the pahole version changes
between builds, similar to how it happens for compiler version change
via CC_VERSION_TEXT.
Define PAHOLE_VERSION in the top-level Makefile and export it for
config builds. Set CONFIG_PAHOLE_VERSION default to the exported
variable.
Kconfig records the PAHOLE_VERSION value in
include/config/auto.conf.cmd [1].
The Makefile includes auto.conf.cmd, so if PAHOLE_VERSION changes
between builds, make detects a dependency change and triggers
syncconfig to update the kconfig [2].
For external module builds, add a warning message in the prepare
target, similar to the existing compiler version mismatch warning.
Note that if pahole is not installed or available, PAHOLE_VERSION is
set to 0 by pahole-version.sh, so the (un)installation of pahole is
treated as a version change.
See previous discussions for context [3].
