or if you want samething smaller, download a specific kernel source
from:
https://www.kernel.org/

Here is a guide on how to buile the kernel:
https://phoenixnap.com/kb/build-linux-kernel
The debian howto is a little confusing, start at sec.4.6
https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html

If you use "make menuconfig" the config mentioned above is in
"Device drivers -> Graphics support", put a "y" in this entry:

 [ ]   Enable additional push buffer debugging    

There are a lot of choises in the kernel config, so the hard part is
to make the right choises.
