Hi Isoken,
This may be related to the directory permission or memory available. Check this

try with https instead of git:

git clone https://kernel.googlesource.com/pub/scm/linux/kernel/git/gregkh/staging.git

Thanks for helping me resolve the former issue, but I have an issue
when running make in the "building kernel step" of the tutorial. Here
is the error message:
make[3]: *** No rule to make target 'debian/canonical-certs.pem',
needed by 'certs/x509_certificate_list'.  Stop.
make[2]: *** [scripts/Makefile.build:480: certs] Error 2
make[1]: *** [/home/vagrant/git/staging/Makefile:1913: .] Error 2

This is discussed here:

https://stackoverflow.com/questions/67670169/compiling-kernel-gives-error-no-rule-to-make-target-debian-certs-debian-uefi-ce

You can just follow the instructions about removing the whole key thing:

This thread might help you :
lists.debian.org/debian-kernel/2016/04/msg00579.html. In the .config file
copied from /boot find and comment out the lines CONFIG_SYSTEM_TRUSTED_KEY
and CONFIG_MODULE_SIG_KEY. –

Then you can run make olddefconfig before trying again to compile.

Re: [Error]

[Isoken Ibizugbe]

Yes I copied the .config file of the currently running kernel and I'm
using Ubuntu 20.04LTS on a virtual box, I renamed the
CONFIG_LOCALVERSION in the .config and commented out these lines
CONFIG_SYSTEM_TRUSTED_KEY
and CONFIG_MODULE_SIG_KEY, then ran make -j4, but the kernel has been
compiling for 10 hours now. please is this normal?

Thank you for the clarification.

I think your configuration is too big.  You can try make localmodconfig
and see if you get a smaller configuration.

Does your VM actually have 4 cores?

I'm not sure to understand.  You mean that after 10 hours it finally
completed?  Or that you started over and it became faster?

OK, make defconfig will indeed result in a much smaller configuration.  I
don't know if it will boot on your machine.  But if it does, then that's
fine.

Thanks for the help. I made changes to the probe function by adding
the printk line to it 'printk(KERN_DEBUG "I can modify the Linux
kernel!\n");' , compiled and installed the changes , rebooted my VM
and ran 'dmesg | less' test the changes, but can not  find the
changes. please what should I do?

Re: [Error]

[Isoken Ibizugbe]

I am sorry for the confusion. After building and installing the kernel
successfully I didn't edit the grub file, so I didn't see my new
kernel after boot, so I went to do that and reboot, but my VM couldn't
load any kernel at all, I don't know if its because I was using
Vagrant, so I downloaded and installed Ubuntu on the VM to start
afresh, but I have been able to finish the first instruction on
compiling and installing, but my compiled kernel doesn't work, can I
work on it from just the directory?

I think you should check with the mentor(s) for the project(s) that you
are interested in.  In some sense it is time to move on, since the
contribution period is not very long.  But if you need to be able to
obtain a running kernel for your project, then you need to be able to do
that.

Maybe you can use kexec: https://wiki.archlinux.org/title/kexec
The following arguments: /boot/vmlinuz-linux --initrd=/boot/initramfs-linux.img
both correspond to the kernel you want to boot.

If you changed a staging driver, it seems thta you will not want to boot
that code, because you don't have the relevant device.

So you can do make allyesconfig and then it will have as much selected as
possible.  The you should be able to make the driver you changed.  See the
tutorial for how to compile and single file and how to a compile a
complete driver.
