<pre>Hello,
I have isolated a bug, I think with the intel driver no longer supporting
tv-out (svideo/component/composite) on newer kernels.
The problem appears to be in drivers/gpu/drm/i915/intel_tv.c, in "void
intel_tv_init(struct drm_device *dev)" (line 1550 approx)
the function tv_is_present_in_vbt return 0 so it aborts at this line.
if (!tv_is_present_in_vbt(dev)) {
DRM_DEBUG_KMS("Integrated TV is not present.\n");
return;
}
Upon inspecting the function static int tv_is_present_in_vbt(struct drm_device
*dev), the device enumeration only cycles through the lvds and the vga out.
As a stop-gap for my htpc, I just changed the return value of that function to
1 and now everything works well for me, but this is a duct tape fix and not
kernel worthy.
I hope this helps, at this point my better half is using the htpc and it would
be very dangerous to my wellbeing if I reboot with the old kernel and
drm.debug=0x6.
Thanks,
Matthew</pre>
