1  Linux Stuff / Kernel / Re: D2Plug 2.6.32.55 new kernel available on: February 04, 2012, 09:01:54 AM
The nice feature would be adding support for HDMI/CEC with TDA19988 to control AV systems.

Indeed that might be confusing. Based on my testing SPDIF (Tonsil) and HDMI is the same sink.

I can confirm that recent version of MAD lib is not working correctly and eventually I compiled MPD without MAD support and use mpg123 instead. That was the first problem I came across with my D2Plug wanted to run MPD.

In terms of MPD configuration here is the relevant snipplet from mpd.conf
Code:
audio_output {
        type            "pulse"
        name            "Headphone"
        sink            "alsa_output.platform-soc-audio.0.analog-stereo"   
}

audio_output {
        type            "pulse"
        name            "Amplituner"
        sink            "alsa_output.platform-soc-audio.1.analog-stereo"
}

Headphone is obviously analog jack output and Applituner is SPDIF connected to my home audio set.

Any other audio_outputs are commented in my conf file.
The PA configuration is just default and I haven't changed anything as far as I remember.

It works fine now for me however I altered the pm.c to ignore deep-idle mode and recompiled the kernel.
If you come to that point I'll share more details if needed.

If you have any chance to connect any display to the plug you can check the audio under gnome. There is applet allowing selection of the default sound output. Anyway the configuration of MPD is independent of the configuration of gnome. That is a drawback that changing the volume under gnome I have no control on the volume of music played by MPD. This is not affecting my setup as my plug is also headless.

good luck and do not hesitate to ask if you have more question. I'm fine with sharing me experience.

Does it mean that we got stuck with D2Plug and should have gone for CuBox rather. I expect that D2 will be maintained as well.

Hi Team,

do you have any plans to release new kernel for d2plug?

Is there any git repository available for d2plug?

I can't find it on git.kernel.org so I guess is not merged yet.
It is also not available on git.marvell.com nor kernel.ubuntu.com/git

Cheers,
klaus

Sorry, but it's not useful at all.

The problem is related to Deep-Idle mode implementation in Kernel and needs to be fixed with kernel patch.

Waiting for guys from Marvell for commenting....

I really appreciate you want help but in my first post I wrote that it happens when gdm is stopped.
My D2Plug is headless. I don't run GNOME nor KDE. No screensaver. The Caffeine application is just an applet which helps you when you watch flashvideo or play the games to prevent the screensaver activation. I've got similar application on my Mac.

The problem is related to power management functionality implemented in kernel for mach-dove/plat-orion architectures.

When the screen is blanking then the PMU goes into Deep-Idle mode and the sound starts chopping.
The arch/arm/mach-dove/pm.c modification forcing the PMU to stay in eBook mode (whatever it means) when screen is blanking prevents of getting into sound problems.

It was probably assumed that blanking screen should disable the sound output on HDMI and which is actually happening.
But there are also S/PDIF and Analog outputs that should not be affected.

Anyone from Marvel can comment on this?

Anyone from Marvel can explain how the power management is implemented on D2plug?
How to prevent the system of going to idle state?
10  Linux Stuff / General Linux questions / D2Plug - voice is chopping/slowdown when backlight power down on: November 24, 2011, 06:40:25 AM
Hi,

I have installed mpd and configured for pulseaudio. My audio receiver is connected to SPDIF but the problem is observed also on the earphone analog output.

The audio starts chopping and slowing down after certain amount of time.
I correlated it with following log message:
D2Plug kernel: [  630.602506] backlight power down

This error message is generated by dove_bl.c in kernel as I could grep out.

It happens even when gdm is stopped.

How to prevent it?
Cheers,
klaus

llamich: Try this:
http://www.plugcomputer.org/plugforum/index.php?topic=5942.0
and please avoid of using this thread to solve another problem. This is related to the log flooding issue.

So of there are others facing the same issue with log flooding it seems that this is not hw related issue.
Anyone from Global Scale/Marvell can have a look on this?
Cheers,
klaus

Hi Moderators,
can we have a separate forum category for all the stuff related to D2Plug. It's quite new platform with new software and we may expect more threads related to this hw platform thus.
13  Hardware and U-Boot firmware / Hardware / Re: D2Plug - Log files flooded with error mesages related to /dev/sda on: November 21, 2011, 06:40:42 PM
I've found that udisks-daemon was polling all the devs: /dev/sda /dev/sdb and /dev/sdc probably for automounting.

I just eliminated it by adding the following line:
Code:
KERNEL=="sda*", ENV{UDISKS_DISABLE_POLLING}="1"

to /lib/udev/rules.d/80-udisks.rules

however there's still open question remaining.
Is it a bug in kernel sata module or udisks itself causing error message when accessing not connected disk or just my controller port is broken.
Unfortunately I can't check it out because I haven't got the eSATA device.

Anyone can check the logs if the same error messages appear?
14  Hardware and U-Boot firmware / Hardware / Re: D2Plug - Log files flooded with error mesages related to /dev/sda on: November 18, 2011, 12:43:52 PM
What for? I don't have drive connected to eSATA interface on D2PLUG.

On D2Plug:
/dev/sda seems to be eSATA - I have no eSATA to check it
/dev/sdb is SD Card (external)
/deb/sdc is USB drive

It look like kernel is trying to do something with device /dev/sda which generates this massive error log.

I don't see any reason for installing smartmontools to solve this issue.
15  Hardware and U-Boot firmware / Hardware / Re: D2Plug - Log files flooded with error mesages related to /dev/sda on: November 17, 2011, 11:27:45 PM
Nothing is connected to eSATA. I don't even have any eSATA device to check what happens when I connect it.

I don't think this is normal situation having a massive error message flooding to the log files.
It stopes when I ordinary remove the sda devce with 'rm /dev/sda'.
I don't think this is a solution. BTW I put this command into the /etc/rc.local.

It seems to be a bug in kernel.

Is anyone else facing the same issue?
