* gnu/packages/aux-files/linux-libre/4.19-x86_64.conf: Build DRM BOCHS support
as a module. It adds DRM support for BOCHS dispi vga interface used by
qemu (-vga std option). It will also be useful for QEMU 3.0 to enable the new
"bochs-display" display device.

Hi,
This article might help to understand what's new in QEMU 3.0 with VGA
emulation.

Thanks,
Mathieu

Perhaps we should enable it on AArch64 as well? Mostly so that configs
don’t diverge too much.
Otherwise it LGTM. Mark, WDYT?
Thanks,
Ludo’.

Hi Ludo,

It is already built as a module on our arm and arm64 configs. The arm
config was taken from Debian and not derived from GuixSD intel configs,
so it explains the divergence. I guess it is the same for the arm64
config.
Thanks,
Mathieu

Looks good to me, please push.

I just checked, and it's already enabled in our ARM and ARM64 configs.
FYI, our x86_64 and i686 configs were originally copied from
<https://jxself.org/git/kernel-configs.git>, and that's where the
decision to disable CONFIG_DRM_BOCHS originally came from. In that
repo, you can see signs of indecision about whether to include that
module. It was disabled in Jason's configs for 3.14-4.6, enabled in
4.7-4.15, disabled again in 4.16-4.18, and then enabled again in 4.19.
Since around 4.1 or 4.2, I've stopped looking at
<https://jxself.org/git/kernel-configs.git> and been using my own
judgement about new kernel configuration options brought to my attention
by "make oldconfig", but I haven't reviewed most of the older options.
Anyway, thanks for the patch!
Mark

Thank you for the explanation and the review! Pushed as
