Title: How to make a new igb drivers
Post by: zbs888 on November 05, 2020, 08:41:43 PM

Hi,i am a newbie.I want to make a new igb drivers in tc.
Here is my env:

Code: [Select]

Linux box 5.4.3-tinycore64 #2020 SMP Tue Dec 17 17:38:30 UTC 2019 x86_64 GNU/LinuxAnd i do this:

Code: [Select]

tar Jxfv linux-5.4.3-patched.txz -C /usr/src
ln -s linux-5.4.3 linux
ln -sf /usr/src/linux /lib/modules/5.4.3-tinycore64/build
ln -sf /usr/src/linux /lib/modules/5.4.3-tinycore64/source
cp config-5.4.3-tinycore64 /usr/src/linux/.config
make oldconfig
make headers_install
cd /mnt/sda1/soft/igb-5.4.6/src/
make install
And i got this:
common.mk:138: Missing System.map file - depmod will not check for missing symbols
make[1]: Entering directory '/usr/src/linux-5.4.3'
/mnt/sda1/soft/igb-5.4.6/src/Makefile:43: *** Cannot find common.mk build rules.  Stop.
make[1]: *** [Makefile:1652: /mnt/sda1/soft/igb-5.4.6/src] Error 2
make[1]: Leaving directory '/usr/src/linux-5.4.3'
make: *** [Makefile:86: default] Error 2

So,how to do next?

Hi zbs888
Welcome to the forum.

I thing the  igb.ko  driver is included in the base system. Take a look in here:

Code: [Select]

/lib/modules/5.4.3-tinycore64/kernel/drivers/net/ethernet/intel/igb/

Hi Rich,
Thanks for your reply.I knew the igb driver in the catalog.But i still want to compile the newer driver........

After “make oldconfig” you need “make modules”.

Hi zbs888
I did some searching through the forum and pieced these instructions together:

sudo ln -s $PWD /lib/modules/5.4.3-tinycore64/build

cd /mnt/sda1/soft/igb-5.4.6/src/
# This should install in the cureent directory under  lib/modules/5.4.3-tinycore64/......
make INSTALL_MOD_PATH=$PWD install
Let us know if this worked.

Thanks, it's a great help.

Code: [Select]

tce-load -i elfutils-dev
make mrproper
cp /mnt/sda1/tce/optional/src/kernel/config-5.4.3-tinycore64 /usr/src/linux/.config   
make oldconfig
make prepare
make modules_prepare
Then:

Code: [Select]

Finaly,i got a igb.ko file in src.

Code: [Select]

----- Snip -----

  WARNING: Symbol version dump ./Module.symvers
           is missing; modules will have no dependencies and modversions.

 ----- Snip -----



That warning is because you skipped these steps:

Code: [Select]

wget http://repo.tinycorelinux.net/11.x/x86_64/release/src/kernel/Module.symvers-5.4.3-tinycore64.gz
cd  linux-5.4.3
cp ../Module.symvers-5.4.3-tinycore64.gz ./Module.symvers.gz
gunzip Module.symvers.gz
make SUBDIRS=scripts/mod
If the module does not want to load, this is probably the reason.

As of linux-5.something this bit:

Code: [Select]

cp ../Module.symvers-5.4.3-tinycore64.gz ./Module.symvers.gz
gunzip Module.symvers.gz
make SUBDIRS=scripts/mod
..no longer works so, unless there is a different work around, you are obliged to use "make modules", which will build all modules
