Dear Debian folks,


The Kconfig help text for `AGP` is a little confusing (and maybe 
outdated?) [1].

> You should say Y here if you want to use GLX or DRI.

Although selected in Linux’ default x86 configs

     arch/x86/configs/i386_defconfig
     arch/x86/configs/x86_64_defconfig

I do not think, it’s necessary to build this into the Linux kernel.

     $ grep AGP /boot/config-5.6.0-1-amd64
     CONFIG_AGP=y
     CONFIG_AGP_AMD64=y
     CONFIG_AGP_INTEL=y
     CONFIG_AGP_SIS=y
     CONFIG_AGP_VIA=y

The init functions are unnecessarily called as shown by `initcall_debug`.

So, it’d be great if this driver was built as a module (as DRM is also 
built as a module). This will reduce the size of `bzImage` a little.


Kind regards,

Paul
