problem compiling Kernel 6.1.27-gentoo-r1

Post #1 of 5 (142 views)

I'm trying to install Gentoo in my new machine
& have got to the step of compiling a kernel.
I used the config file from my present machine, did 'make oldconfig'
& have then done 'make menuconfig' to include drivers etc.

The 'make' stage goes on for a long time, then crashes doing
'UPD drivers/base/firmware_loader/builtin/rtl_nic/rtl8168g-2.fw.gen.S'
with message "make [5] *** No rule to make target
'lib/firmware/rtl_nic/rtl8168g-2.fw' needed by 'drivers/base/firmware_loader/
builtin/rtl_nic/rtl8168g-2.fw.gen.o' Stop".

The relevant line in Menuconfig is 'DeviceDrivers > NetworkDeviceSupport >
EthernetDriverSupport' under 'Realtek devices'.
I've tried it with 'Realtek8169/8168/...' 'Y' or 'M' or 'N'
& also with 'Realtek devices' as 'N'. I also tried a 'make clean'.
The same error goes on happening.

Since I don't have anything by Realtek for networking
-- sound uses Realtek -- , I can't understand the behaviour above.

Can anyone offer any advice ?

The compilation complains it is missing the firmware required by a realtek
NIC, probably a setting inherited from the config settings of the old kernel?
You eventually compiled it with "N". I suspect the order in which you
configured/compiled it plays a role in this error.

Since you do not have this hardware, set it to "N", then run:

make clean && make && make install modules_install .... <whatever options you
normally use here>.

Meanwhile, check if you have the firmware file it asks for, which would have
been installed as part of 'sys-kernel/linux-firmware':

$ ls -la /lib/firmware/rtl_nic/rtl8168g-2.fw
-rw-r--r-- 1 root root 4896 May 18 16:15 /lib/firmware/rtl_nic/rtl8168g-2.fw

$ qfile /lib/firmware/rtl_nic/rtl8168g-2.fw
sys-kernel/linux-firmware: /lib/firmware/rtl_nic/rtl8168g-2.fw

When you update world after you have compiled your new kernel, linux-firmware
will be installed and the missing file will be available anyway - although no
longer needed or used by the kernel.

Could this be the manually defined list of firmware blobs to include in
the kernel image, and not something automatically pulled in by a driver?

I'm not sure what's the quickest way to check, perhaps this works?:

grep CONFIG_EXTRA_FIRMWARE /usr/src/linux/.config

This will not resolve the problem of a missing firmware file. It is missing
in the filesystem.

The problem was 'make oldconfig', which used a 5 year-old .config .
For some reason, the resulting .config insisted on installing
the Realtek driver, which wasn't available.

I cut the Gordian knot by moving the other .config's out of the way
& doing a raw 'make menuconfig'. Then the kernel compiled.
If it needs further tweaking, esp for missing drivers, I can do it later.

It's too late to do further steps today,
so we'll see what happens when I try booting from the new kernel.

Thanks for the various pieces of help.
