Subject: KCONFIG_ALLCONFIG + allmodconfig = brokenness
Date: Sun, 29 Dec 2013 17:32:47 -0800 [thread overview]
Message-ID: <52C0CD3F.7080808@zytor.com> (raw)
When KCONFIG_ALLCONFIG is used with "make allmodconfig", the result ends
up being largely the same as "make allyesconfig", because the resulting
kernel ends up with CONFIG_MODULES=n:
How to reproduce:
: tazenda 125 ; make O=../o.test allmodconfig
GEN /home/hpa/kernel/o.test/Makefile
scripts/kconfig/conf --allmodconfig Kconfig
#
# configuration written to .config
#
: tazenda 126 ; grep CONFIG_MODULES ../o.test/.config
CONFIG_MODULES_USE_ELF_RELA=y
CONFIG_MODULES=y
: tazenda 127 ; env KCONFIG_ALLCONFIG=/dev/null make O=../o.test
allmodconfig
GEN /home/hpa/kernel/o.test/Makefile
scripts/kconfig/conf --allmodconfig Kconfig
#
# configuration written to .config
#
: tazenda 128 ; grep CONFIG_MODULES ../o.test/.config
CONFIG_MODULES_USE_ELF_RELA=y
# CONFIG_MODULES is not set
