Sigh,
The drm-nouveau-acpi-edid-fallback.patch recently had some code added to
nouveau_connector.c to do some fallback to ACPI. It looks like this:
@@ -718,6 +718,14 @@ nouveau_connector_create_lvds(struct drm
}
}
+ /* Let's try ACPI */
+ if (!nv_connector->edid && !nv_connector->native_mode &&
+ !dev_priv->vbios.fp_no_ddc &&
+ !nouveau_acpi_get_edid(dev,connector)) {
+ nv_connector->edid =
+ (struct edid *)&nv_connector->acpi_edid;
+ }
+
if (!nv_connector->edid)
goto out;
However, there is no ACPI on PPC/PPC64, so the build fails with this:
drivers/gpu/drm/nouveau/nouveau_connector.c: In function
'nouveau_connector_create_lvds':
drivers/gpu/drm/nouveau/nouveau_connector.c:726: error: 'struct nouveau_connector'
has no member named 'acpi_edid'

I'm pretty sure the above code should be wrapped with #ifdef CONFIG_ACPI or
something similar. The structure add in nouveau_connector.h is at least.
