Shall we move or cc this discussion on audio driver side to ALSA ML? Oops I thought I had cc'ed these patches to alsa-devel as well when I sent them. I think we also need to decide how to manage PCM devices for DP MST. Now the HD-A driver create a PCM device for each pin, and the

Re: [Intel-gfx] [alsa-devel] [RFC] set up an sync channel between audio and display driver (i.e. ALSA and DRM)

2014-05-21 Thread Raymond Yau
This RFC is based on previous discussion to set up a generic communication channel between display and audio driver and an internal design of Intel MCG/VPG HDMI audio driver. It's still an initial draft and your advice would be appreciated to improve the design. The basic idea is to

Re: [Intel-gfx] [alsa-devel] Need your advice: Add a new communication inteface between HD-Audio and Gfx drivers for hotplug notification/ELD update

And I have a question: how to assure the audio/gfx client find its right peer? On a x86 platform, there can be an integrated GPU and an discrete GPU. So there can be two audio controllers and two GPUs. We need to assure audio controller find the proper GPU, and vice versa. Maybe we need the
