Description jakub_lach 2021-01-31 11:21:23 UTC
I use i915kms, yt radeonkms.ko and amdgpu.ko are also always installed under /boot/kernel, it's a change in behavior from 12-STABLE. As I use MODULES_OVERRIDE=, those take more space than the whole kernel altogether.
Comment 1 Niclas Zeising freebsd_committer 2021-02-01 16:09:53 UTC
Which kernel modules are you referring to as not needed?
The modules in /boot/kernel is built together with the kernel, you should not have any graphics related kmods there (the old drm drivers in base are removed in 13).
Do you mean /boot/modules?

Today, there is no way in the port to specify just one of the drivers, it would just lead to a lot of complexity in the port for very little gain.

I use MODULES_OVERRIDE=, nontheless, when I build kernel, radeonkms.ko, amdgpu.ko and i915kms.ko are build together and installed under /boot/kernel/. I only need i915kms. (see below)

The ones under /boot/modules are provided by ports (drm-fbsd13-kmod-5.4.62.g20210122_3), as I understand.

I think some changes in 13 introduced auto-rebuild of kernel modules provided by ports and now they are doubled (?)

Sort of.  Ports that install kmod sources somewhere in /usr/local (I forgot exactly where) will have them built together with buildkernel.
drm-fbsd13-kmod used to do that, but it has been disabled by default.  It's an option, check your options for drm-fbsd13-kmod and disable the sources and reinstall and it will stop.

Comment 6 Emmanuel Vadot freebsd_committer 2021-02-02 12:15:09 UTC
Yes I only did it in drm-current-kmod for now.
This is now done for drm-fbsd13-kmod as well as of 563797/563798.
