Hi Daniel,

We are trying to figure out the kernel defconfig used for this build error.

Great!

From the logs you have provided, I am not able to locate "CONFIG_SERIAL_SH_SCI=m" in any of cip kernel config file for x86 (branch:-v4.4.126-cip22).

We planned to enable some more kernel-config option in shmobile defconfig (for eg:- CAN,SGTL5000 etc..) in future.

We would like to avoid the build error like the below one in future. So can you please help us in locating the defconfig file?

I got this by triggering the CI build on [1]. Though from the report I'd
say it was triggered by running allmodconfig on x86_64.


Let's try it on x85_64:

$ make O=/tmp/build-test allmodconfig
$ grep CONFIG_SERIAL_SH_SCI /tmp/build-test/.config
CONFIG_SERIAL_SH_SCI=m
CONFIG_SERIAL_SH_SCI_NR_UARTS=2
CONFIG_SERIAL_SH_SCI_DMA=y


On ARM I get the same:

$ CROSS_COMPILE=arm-linux-gnu- make ARCH=arm O=/tmp/build-test allmodconfig
$ grep CONFIG_SERIAL_SH_SCI /tmp/build-test/.config
CONFIG_SERIAL_SH_SCI=m
CONFIG_SERIAL_SH_SCI_NR_UARTS=2
CONFIG_SERIAL_SH_SCI_DMA=y


And now for shmobile_defconfig:

$ CROSS_COMPILE=arm-linux-gnu- make ARCH=arm O=/tmp/build-test shmobile_defconfig
$ grep CONFIG_SERIAL_SH_SCI /tmp/build-test/.config
CONFIG_SERIAL_SH_SCI=y
CONFIG_SERIAL_SH_SCI_NR_UARTS=20
CONFIG_SERIAL_SH_SCI_CONSOLE=y
# CONFIG_SERIAL_SH_SCI_DMA is not set


I'd say you need also to build with allmodconfig the kernel to
trigger this problem.


Thanks,
Daniel

I also tagged an intermediate version 4.4.120-cip21 before merging
from 4.4-stable.

Sorry, that intermediate version was actually 4.4.126-cip21. It
includes the stable changes but not the improvements to Renesas
hardware support that are in -cip22.

While working on the cip-rt spin I got following error from our ci build
server:

Errors:
-------
all annotations:
~~~~~~~~~~~~~~~~
ERROR: "mctrl_gpio_disable_ms" [drivers/tty/serial/sh-sci.ko] undefined!

ERROR: "mctrl_gpio_init" [drivers/tty/serial/sh-sci.ko] undefined!


I think this was introduced by 8bac17a7f510 ("serial: sh-sci: Add support for
GPIO-controlled modem lines"). serial_mcrtl_gpio.h provides for GPIOLIB
and !GPIOLIB an implementation.

I am slightly confused, though I haven't spend a lot of time yet to figure out
what's going on.

Thanks,
Daniel
