Hi,
we've got a regression report about Intel HDMI. It seems that the recent change to skip the component binding (commit c9db8a30d9f0) throws away the devices incorrectly on IvyBridge. I guess the similar issue could happen on older chips. The bug report is found at https://bugzilla.opensuse.org/show_bug.cgi?id=1200611
Judging from the logs there, on IvyBridge, the GPU is
00:02.0 0380: 8086:0162 (rev 09) DeviceName: Onboard IGD Subsystem: 1043:84ca Flags: bus master, fast devsel, latency 0, IRQ 27 Memory at f7800000 (64-bit, non-prefetchable) [size=4M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at f000 [size=64] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915
while HD-audio is
00:1b.0 0403: 8086:1e20 (rev 04) Subsystem: 1043:84a8 Flags: bus master, fast devsel, latency 0, IRQ 31 Memory at f7d10000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel
Unlike Haswell, IVB has no dedicated HDMI audio controller, and it's connected on HD-audio bus of 00:1b.0.
Kai, could you check this issue?
thanks,
Takashi
