I'm experiencing a spot of trouble with this commit:
commit aad730d0704545ad97654bd929b0aba05adb1436
Author: Takashi Iwai <tiwai@xxxxxxx>
Date: Mon Dec 2 13:33:57 2013 +0100
ALSA: hda - Always do delayed probes for HD-audio devices
That adds some code:
#ifndef CONFIG_SND_HDA_I915
if (chip->driver_caps & AZX_DCAPS_I915_POWERWELL)
dev_err(card->dev, "Haswell must build in CONFIG_SND_HDA_I915\n");
"Oh, bother" -- Winnie the Pooh
So I go looking how to fix this, and 'make menuconfig' tells me:
Symbol: SND_HDA_I915 [=n] x
x Type : boolean x
x Defined at sound/hda/Kconfig:8 x
x Depends on: SOUND [=y] && !M68K && !UML && SND [=y] && DRM_I915 [=n] && SND_HDA_CORE [=y]
And why is DRM_I915=n?
# lspci | grep NV
01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [NVS 5200M] (rev a1)
Because this Dell laptop has NVidia graphics onboard, and no sign of I915
graphics that needs I915 DRM.
I think the infrastructure that you're trying to re-use from DRM_I915 needs
to be moved to another symbol which can be SELECT/DEPEND by both DRM_I915
and SND_HSA_I915.
Comments/suggestions?
