Hi,
I'm in the process to reduce the Fedora s390x kernel's size and build time by disabling drivers for devices that can't appear on the mainframe. But I'm getting 2 kinds of errors
first is ... + echo '# s390' + cat .config + CheckConfigs configs/kernel-4.11.0-s390x.config temp-kernel-4.11.0-s390x.config + ./check_configs.awk configs/kernel-4.11.0-s390x.config temp-kernel-4.11.0-s390x.config + '[' -s .mismatches ']' + echo 'Error: Mismatches found in configuration files' Error: Mismatches found in configuration files + cat .mismatches Found # CONFIG_HID is not set, after generation, had CONFIG_HID m in Fedora tree Found # CONFIG_HWMON is not set, after generation, had CONFIG_HWMON m in Fedora tree Found # CONFIG_I2C is not set, after generation, had CONFIG_I2C m in Fedora tree Found # CONFIG_NEW_LEDS is not set, after generation, had CONFIG_NEW_LEDS y in Fedora tree + exit 1
This is after setting the options ^^^ to "N" in their files under baseconfig/s390x/.
the second one is ... + rm temp-kernel-4.11.0-ppc64p7.config + for i in '*.config' + cat kernel-4.11.0-s390x.config + mv kernel-4.11.0-s390x.config .config ++ head -1 .config ++ cut -b 3- + Arch=s390 + make ARCH=s390 listnewconfig + grep -E '^CONFIG_' + '[' -s .newoptions ']' + cat .newoptions CONFIG_RESET_CONTROLLER + exit 1
This is after disabling all Ethernet drivers (drivers/net/ethernet) except Mellanox
What am I doing wrong or what else I must change?

This is a check designed to make sure that what we specify in the Fedora configurations match what is generated via Kconfig. The output is stating that the Fedora tree has (e.g.) CONFIG_HID=m set but when run against the kernel configuration generation it comes out as # CONFIG_HID is not set. The easiest way to fix this is to make all those options match whatever is being generated (so mark all those options not set)
the second one is ...
- rm temp-kernel-4.11.0-ppc64p7.config
- for i in '*.config'

This is saying that CONFIG_RESET_CONTROLLER isn't specified as a Kconfig value for s390x. You need to explicitly set it.
Thanks, Laura

thanks to both you and Justin (seems it was private reply only), the updates will follow
