Bug ID: 11641
Summary: linux kernel .config timestamp always out of date
fixed with KCONFIG_NOSILENTUPDATE
Product: buildroot
Version: 2018.11.1
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: dcraw101 at yahoo.com
CC: buildroot at uclibc.org
Target Milestone: ---
Just noticed this when migrating from kernel 4.9 to 4.19. I noticed that now
in the linux kernel build dir the .config timestamp is always later than the
.stamp_kconfig_fixup_done. So every incremental buildroot make causes the
kernel build to always run starting at the kconfig fixup phase.
I traced the problem to somewhere in the kernel syncconfig step in the kernel
"build" phase. I think it is related to this new kernel 4.19 commit.
16952b77d8 kconfig: make syncconfig update .config regardless of
sym_change_count
If I define KCONFIG_NOSILENTUPDATE in my environment the problem goes away and
the timestamps are correct. Should buildroot set this env variable? I am not
sure what the other side affects would be.
