HDMI CEC Promoted Out Of Staging For Linux 4.10

[Serafean]

Is this hookable into current graphic drivers? Like r600, nouveau?

No. The hardware support isn't there. You'll need to buy https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter , but this is only supported by a userspace driver (because it exposes only /dev/ttyACM0 )

I mean in the kernel - I know most consumer devices have it - i.e. can I control a TV or sound system plugged into my PC yet, or is this just the infrastructure with no users yet

Umm, how do you think consumer devices can use it, again? These devices have Linux Inside.

The support for that depends from the GPU driver, or (for embedded) the display controller that is physically operating the HDMI port. On Linux Desktop most drivers don't support it. Raspi drivers should support it.

I don't now if is the same thing, but the last time I tested XBMC a couple years ago in a Raspberry Pi (the first one), the remote of a Sony TV was fully recognized and I could navigate and use almost all buttons of the remote on the XBMC UI.

General rule of thumb, report bugs the more upstream as possible.

In your case, you should try with another distro too to make sure it isn't a Debian-only issue, and if there is the same problem you can go in bugtracker or mailing list of Linux TV https://www.linuxtv.org/ as they are the ones writing the drivers for TV cards on Linux.

List	Description
linuxtv-commits	Notifies about commits on master LinuxTV repositories (v4l-dvb and dvb-apps)
linuxtv-cvs	commit mails from linuxtv.org CVS
media-workshop	Mailing list for media workshop related discussions
V4L2-library	Temporary Mailing list for discussing V4L2 Userspace library
vdr	VDR Mailing List

Which one of them? Actually, it's quite confusing

Yeah it is.

Does Raspberry already use this new CEC framework? What end user applications support it?

I'm half sure that Sony also managed to make it work only for other Sony products.

By some un-explainable miracle : No. SONY TVs won't refuse to work with any other HDMI-CEC.

Personal experience : my parent use a Sony Bravia flat LCD panel, and use a Panasonic HD / DVD recorder, and both devices talk to each other.
(e.g.: You can control which ever device happens to be in focus with whatever remote control you happen to have at hand)

I'm sure some engineer at SONY is going to get sacked for having forgotten to put the usual limitations in place.

Other than that, it hasn't seen much adoption.

I think Raspberry Pi actually support CEC on their HDMI port. (without needing a separate USB-CEC dongle like normal desktop GPU).
And I seem to remember that Kodi supports it (but my memory might be failing me).

I wanted to automatically turn on my TV from a Intel Compute Stick, and was quite surprised and annoyed when I found that Intel has not implemented HDMI-CEC in _any_ of their graphics solutions: https://communities.intel.com/message/386488#386488
