When i try hitting / and then typing one of the names of a module and hitting enter in menuconfig, it doesn't find anything. How can i find which options contain these specific modules? I've got lots of space so i'm just gonna compile all of these directly into my kernel.

jacobr8893 ... capitalise your search terms, so I915 rather than i915.

egrep -i (i915|snd_hda_intel) /usr/src/linux/.config:
CONFIG_DRM_I915=y
CONFIG_DRM_I915_KMS=y
CONFIG_DRM_I915_FBDEV=y
# CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT is not set
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_I915=y

HTH & best ... khay

jacobr8893,

Welcome to Gentoo.

Many search terms will be hidden. They become hidden when something they depend on is hidden.
Try pressing z in menuconfig so all the hidden items are shown.

e.g.
Code:
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_I915=y
and all the other CONFIG_SND options will be hidden if the ALSA option is off.


khayyam,

I'm pretty sure that the kernel search is not case sensitive. That's not because I've checked, I'm just lazy when I type.

Neddy ... I just did ... and you're correct. I'd assumed it was because Kconfig has them uppercase, and that seemed the only reasonable explanation for 'i915', 'snd_hda_intel', 'rtsx_pci', or 'r8169', "not find[ing] anything", as the OP stated (given that these items would not be hidden as their parents are enabled by default).

best ... khay
