[alsa-devel] [PATCH 00/19] Rework OMAP4+ HDMI audio support
Since RFC version of the patch set: - Split callbacks removal patch away from "Integrated ASoC DAI component driver implementation" patches for easier reading
This set of patches fixes OMAP4+ HDMI audio. The structure of the implementatin looks a bit different than before. Instead of creating a driver specific API for a separate ASoC component driver to connect to, this implementation integrates an the component driver into the HDMI driver.
The idea is to use an existing ASoC component driver API instead of creating a new custom API for each HDMI IP and to avoid splitting the driver to half for separate video and audio parts connected with the API.
The new implementation also uses simple-audio-card for a machine driver instead of having its own HW specific machine driver.
The patches are based on 3.15-rc2 merged with git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next and git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git work/dss-dt-omap5
Everything is pushed here here: git://git.ti.com/~jyrisarha/ti-linux-kernel/jyrisarhas-audio-video-linux-feature-tree.git omap-hdmi-audio

The hdmi driver provides a digital audio interface (DAI) which can be used to transmit audio over the HDMI cable. The ASoC DAI component driver provides just that functionality. A machine, platform, and (in this case a dummy) codec component driver is also needed for a complete ALSA device functionality.
Anyway, I look into Mark's suggestion of instantiating all the necessary component drivers from the HDMI driver.
Best regards, Jyri
The OMAP5 HDMI audio implementation needs HDMI_AUDIO_LAYOUT_6CH in hdmi_core_audio_layout enum. I found the correct value from ti-linux 3.8 tree.

This fix is independent of the rest of the series, so I'll already pick this one to my 3.16 omapdss branch.

Removes the OMAP5 HDMI audio callbacks for an external audio driver and the old external DAI driver does not work anymore after this patch.

Maybe this is how this has to be done, but I'll still ask:
Considering that the HDMI audio is basically inseparable part of the OMAP HDMI video, and if a board has HDMI video connector connected to the SoC's HDMI, then it has HDMI audio.
So all of the above .dts changes are already implied when we have HDMI video on the board. Is there no way to prevent every board needing to add those exact same nodes to get HDMI audio?

You can always instantiate devices directly from the HDMI controller code, there's no need to put things in DT at all.

Since RFC version of the patch set:
- Split callbacks removal patch away from "Integrated ASoC DAI component driver implementation" patches for easier reading
This set of patches fixes OMAP4+ HDMI audio. The structure of the implementatin looks a bit different than before. Instead of creating a driver specific API for a separate ASoC component driver to connect to, this implementation integrates an the component driver into the HDMI driver.
The idea is to use an existing ASoC component driver API instead of creating a new custom API for each HDMI IP and to avoid splitting the driver to half for separate video and audio parts connected with the API.
The new implementation also uses simple-audio-card for a machine driver instead of having its own HW specific machine driver.
Can you guys please post this split into the following separate parts for the maintainers to merge:
- ASoC changes - DSS changes - DTS changes
And once those are all in, please post the defconfig changes.
Regards,
Tony

Tony, this series will get delayed until 3.17, but I'd like to merge the HDMI DMA channel changes to omap4/omap5.dtsi already to 3.16. They are patches 13 and 15.
Those are very trivial, but I'd rather have acks from you for all the .dts changes I'll be sending.

hey, this worked straight away :)
But there seems to be something wrong with the channel mapping.
For stereo (speaker-test -c 2) the mapping is correct.
But for -c 4 and -c 8 it gets weird: speaker-test -c 4 -s X # where X is 1-4 1: Front Left is Rear Left 2: Front Right is Rear Right 3: Rear Right is Front Right 4: Rear Left is Front Left
speaker-test -c 8 -s X # where X is 1-8 1: Front Left is Rear Left 2: Center is Rear Left 3: Front Right is Rear Right 4: Side Right is Front Right 5: Rear Right is silent 6: Rear Left is Center 7: Side Left is Front Left 8: LFE - Rear Right
I think you need to check what channel order ALSA expects. I believe speaker-test does the right thing on my HTPC normally connected to my receiver.
Note: I am not 100% sure about the -c 8 results. I might have to do the test again.
Tested on VAR-DVK-OM44 (OMAP4460) with Yamaha RX-A1030 Surround receiver.

I checked the implementation and there was indeed something weird there, but the implementation can not explain the FL and FR channels jumping around. FL and FL should always be the first two channels in all configurations and the implementation does not touch them.
The implementation uses 8ch HDMI setup for anything above 2ch with "Audio InfoFrame Data Byte 4" set to 0x13. According to CEA-861 specs this means following channel order: FL, FR, LFE, FC, RL, RR, RLC, RRC
This is a closest match to ALSA 8ch mapping (according to sound/core/pcm_lib.c) which is: FL, FR, FC, LFE, RL, RR, SL, SR
Current implementation has FLE and FC channels correctly swapped, but it shifts them to last two channels and RL, RR, SL, SR are shifted down to fill the place. This is all wrong and I'll try to come up with a fix for that. Unfortunately I can not test anything beyond 2 ch myself so I would need someone to volunteer to test my patch.

hm, okey. I haven't look at the code but it do seem strange. But with speaker-test -c 4 the front and back are surely swapped here.
I'll do some more testing and also check with my HTPC. btw, I only have a 5.1 setup over here so I can't test all the discrete channels.

hm, okey. I haven't look at the code but it do seem strange. But with speaker-test -c 4 the front and back are surely swapped here.
I'll do some more testing and also check with my HTPC. btw, I only have a 5.1 setup over here so I can't test all the discrete channels.
Current implementation has FLE and FC channels correctly swapped, but it shifts them to last two channels and RL, RR, SL, SR are shifted down to fill the place. This is all wrong and I'll try to come up with a fix for that. Unfortunately I can not test anything beyond 2 ch myself so I would need someone to volunteer to test my patch.
I have the dev kit setup up over here so I can test your patches.
I did some more testing over here.
My HTPC (nVidia ION2 based) works good with speaker-test and all channels are where they are suppose to be.
On the OMAP4 board I tried doing: "while true; do speaker-test -c 4 -s 1; done" and this had an interesting effect. Most of the time FL (Front Left) is swapped with BL (Back Left) but about every 10th time the sound comes out in the FL speaker... So there something weird going on here. Same story for the right channel.
I also noticed that HDMI doesn't always work on boot up, it sometimes fail with: [ 193.985565] omapdss_hdmi 58006000.encoder: audio not supported [ 193.985565] omapdss_hdmi 58006000.encoder: ASoC: can't open interface 58006000.encoder: -19
But after replugging the HDMI connector a couple of times it starts to work.
I'll see if I can try with an old TI OMAP4 kernel (3.4) and see how that works.

hey, this worked straight away :)
But there seems to be something wrong with the channel mapping.
For stereo (speaker-test -c 2) the mapping is correct.
But for -c 4 and -c 8 it gets weird: speaker-test -c 4 -s X # where X is 1-4 1: Front Left is Rear Left 2: Front Right is Rear Right 3: Rear Right is Front Right 4: Rear Left is Front Left
speaker-test -c 8 -s X # where X is 1-8 1: Front Left is Rear Left 2: Center is Rear Left 3: Front Right is Rear Right 4: Side Right is Front Right 5: Rear Right is silent 6: Rear Left is Center 7: Side Left is Front Left 8: LFE - Rear Right
I think you need to check what channel order ALSA expects. I believe speaker-test does the right thing on my HTPC normally connected to my receiver.
I checked the implementation and there was indeed something weird there, but the implementation can not explain the FL and FR channels jumping around. FL and FL should always be the first two channels in all configurations and the implementation does not touch them.

On the 3.4 Variscite kernel: Linux version 3.4.0-1489-omap4 (uri@pluto) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #27 SMP PREEMPT Sun Apr 7 13:27:10 IDT 2013 git://dev.omapzoom.org/pub/scm/integration/kernel-ubuntu.git + Variscite vendor patches
Both speaker-test -c 4 and -c 8 works. All channels are where they are suppose to be.
Hot plugging is broken, though. So the HDMI must be connected on boot, but that might be the Variscite board setup.

That is weird I can not reproduce this problem. I rebooted my panda several times and the audio device was always there. Could it be that the connector is in DVI mode or something?

I checked the ubuntu branch implementation and found that it is quite different in many places, but the one place that affects the i2s channel mapping to HDMI looks exactly the same. So there must be a bug some where else and there is no point trying to fix it by changing the mapping (it would be impossible anyway). I'll compare the implementations further when I have time.
Thanks for your testing. Now I at least now where the bug is not.
