drivers/gpu/drm/nouveau/nouveau_acpi.c:420: undefined reference to `acpi_video_get_edid'

[Borislav Petkov]

Hi,

I'm guessing someone has already triggered this on latest Linus' tree
and has a fix?

drivers/built-in.o: In function `nouveau_acpi_edid':
/w/kernel/linux/drivers/gpu/drm/nouveau/nouveau_acpi.c:420: undefined reference to `acpi_video_get_edid'
make: *** [vmlinux] Error 1

Btw, I got CONFIG_ACPI_VIDEO=m while CONFIG_DRM_NOUVEAU=y and this is
probably the reason for the vmlinux link error.

Thanks.

Does this fix things?

Having nouveau builtin would still allow ACPI_VIDEO to be used as external module if some of the deps for acpi_video
have not been met, which would result in a linking failure. Solve this by only requiring ACPI && X86 to select ACPI_VIDEO.

Not really.

drivers/built-in.o: In function `acpi_video_bus_put_one_device':
/root/kernel/linux/drivers/acpi/video.c:1407: undefined reference to `thermal_cooling_device_unregister'
drivers/built-in.o: In function `acpi_video_device_find_cap':
/root/kernel/linux/drivers/acpi/video.c:842: undefined reference to `thermal_cooling_device_register'

It is CONFIG_THERMAL=m this time.

Argh, next attempt, based on i915's Kconfig.

It seems that not only I have to select ACPI_VIDEO, I also have to select all the dependencies.
Is this a Kconfig bug or working as intended? i915 seems to have a workaround, so I copied it from
there. Except it's currently missing select THERMAL, so I guess it didn't get updated when that got
added.

Yep, this takes care of all deps,

Just to check whether anyone has picked this already - it is triggering
on 3.8 too so it most probably needs a stable tag too.

Thanks.

Ok,

this is not good.

So we have -rc7+, this patch has been out there for 2 months and still
not in Linus' tree.

Linus,

the patch below fixes a build failure here with my custom config. I
think this late in the game, we need some kind of a fix before 3.9 is
released. I'm adding the patch here in case you want to pick it up
yourself.

Thanks.
