Hi
I try to compile 2.6.32-rc5-git3 with enabled CONFIG_DRM_I915_KMS, but got
black screen on boot. After short investigation, i notice that i915.modeset=0
is fine for me.
Here is what i got with modeset=1
[ 1.053570] [drm] Initialized drm 1.1.0 20060810
[ 1.063552] [drm] set up 7M of stolen space
[ 1.608955] [drm] TV-14: set mode NTSC 480i 0
[ 1.758390] fb0: inteldrmfb frame buffer device
[ 1.771866] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor
0
I did just short patch to test my idea, and it was right, wrong output was
detected:
static enum drm_connector_status
intel_tv_detect(struct drm_connector *connector)
{
struct drm_crtc *crtc;
struct drm_display_mode mode;
struct intel_output *intel_output = to_intel_output(connector);
struct intel_tv_priv *tv_priv = intel_output->dev_priv;
struct drm_encoder *encoder = &intel_output->enc;
int dpms_mode;
int type = tv_priv->type;
+ return connector_status_disconnected;
+
It works! So case is invalid detection of output device.
With patch it is:
[ 0.620081] [drm] Initialized drm 1.1.0 20060810
[ 0.632764] [drm] set up 7M of stolen space
