Linaro Audio development ideas for 12.02 and beyond
Hi all, Here is a brain dump for some things I see on the horizon for audio work. Is this complete? Absolutely not. This is meant to be a place to capture and refine ideas before creating cards and/or blueprints for them. In other words, this should compliment the existing work and backlog already in LP. https://wiki.linaro.org/KurtTaylor/AudioBacklog Please edit or send any comments to me.

The e2eaudiotest tool was designed to be in a fully automated environment as a build sniff test that does not require a human to see if the entire audio stack on a particular board/build works "good enough" using a default path.

Setup of official #linaro-multimedia
I just read Fathi's email about the new bots. I didn't want to hijack the existing thread, but I have been considering setting up a new official Linaro irc channel #linaro-multimedia with the meeting bot, etc. As per discussions with Ilias, I would also like to set up a new service, an IRC proxy (bip or ?) for all the multimedia team members. A stored scrollback log might fix timezone problems we have. Would this proxy be something that we could host on a Linaro server? I am fully aware that we are trying to prevent "walled-gardens", but I believe we have a very valid case why we need an irc channel specific to multimedia. We have tried maillists and they have not worked. We would use this channel for technical discussions across timezones, a quick access to a multithreaded store and forward conversation with a log. We would also be able to use this channel for meetings when the main linaro-meeting channel was already being used, hence the need for the meeting bot. We would still use the #linaro channel whenever possible. These are all exploratory ideas at this point. I copied the -dev list so I could get some feedback - Comments? Suggestions? -- Kurt Taylor (irc krtaylor) Linaro Multimedia Team Lead ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

NEON Optimization Forum - LC Orlando
Since we have had over 300 views of NEON optimization on ask.linaro.org, it looks like there is enough interest in continuing the NEON Forum face2face meetings at LC Orlando. I am collecting topics for discussion and wanted to extend an invite to the broader team, to see if anyone wanted to present a short topic. It doesn't have to be an elaborate presentation, maybe just a discussion starter or presenting some findings in your work. I have one presentation already on NEON Optimization Tips and Practices, but could really use at least one more. I was thinking maybe someone from Toolchain, Landing Teams, or someone with previous experience? Would this be something you or someone on your team would be interested in?

End to end audio test - initial drop
Hi everyone, Last week I did an initial drop of the end to end audio test we have been discussing. The idea is fairly simple, play a sine wave and test the audio stack by sampling/testing the sine back in via loopback cable. The app is called testfreq and is driven by a script called e2eaudiotest. It opens and configures the audio device, takes a sample and then does a discrete fourier transformation to find the frequency using the fftw3 library. The test script driver uses speaker-test to play a sine wave at A 440, which for now is the test frequency. It's still basic at this point, but it does work on my system. There is a lot of additional things I'd like to do, initial stack configuration, passing in the device, passing the test frequency, doing more auto detection, clean up the code, etc, but I wanted to start getting feedback. Any and all would be appreciated. Have a look, and if you have a loopback cable, give it a spin: http://git.linaro.org/gitweb?p=people/kurt-r-taylor/e2eaudiotest.git You can also read more about it and check my progress here: https://blueprints.launchpad.net/linaro-multimedia-project/+spec/linaro-mmwg-e2eaudiotesting-basic Enjoy! -- Kurt Taylor (irc krtaylor) Linaro Multimedia Linaro.org <http://www.linaro.org/>* **│ *Open source software for ARM SoCs Follow *Linaro: *Facebook <http://www.facebook.com/pages/Linaro> | Twitter<http://twitter.com/#%21/linaroorg>| Blog <http://www.linaro.org/linaro-blog/> ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
Linaro Audio Roadmap - requirements and comments?
Here is a list of the upcoming audio work for Linaro. I am planning on putting this together into a much more polished roadmap and schedule, but its a start. This is absolutely not set and I am actually looking for any additional requirements and comments. I am sure I have forgotten some, if you don't see your hot topic here, please respond. For the release++ (12.01) === Audio defects - several (~5) open at the moment, panda, android, etc UCM for PulseAudio - follow on work? Initial UCM for Android - ICS is here, time to actually get this started - port to panda first, decide on format/functionality Backlog: == PulseAudio optimization - continue the work I started in 1Q this year e2eAudioTest integration - further integration and feature enhancement of the code I just dropped and will be finishing this release (11.12) Audio Just Works - there is a lot of good usability tweaks that could be done so that the audio stack on the LEBs just work on all the dev boards AudioFlinger optimization - similar to the pulseaudio profiling and power optimization ST-E Alsa support - Landing Team? - this proposed for the landing team, just checking on the status as a possibility Others?

Introduction
Hello, I have been lurking here and on irc for a while and felt like it was time to introduce myself. I have a BB-C4 with all the trimmings and have been booting SD flash with the daily builds and trying different configurations. I have also signed up for weekly testing on the BB. >From the wiki, it looks like I would be most interested in either the Platform Engineering or Working Groups Engineering Units. Specifically, I'd really like to start playing with sound/multimedia, but really anywhere that I can help. Is there any interest in a Middleware:Audio working group? Or does this fit better with the Platform Engineering User Platforms group? I helped form the Linux Foundation (OSDL at the time) Desktop Architects Sound and Multimedia workgroup and could help with that.

Linaro sound support - Beagleboard
Since I personally have not been able to locate this information anywhere, I have created a wiki page to log the testing and experimentation I have been doing with sound. Please ignore if this is duplicate information. Currently info only for Headless and ALIP linaro images, but I plan on adding netbook. Any additional pointers would be greatly appreciated. https://wiki.linaro.org/KurtTaylor/BeagleBoardSound Regards, Kurt Taylor (krtaylor irc) ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

I have seen similar problems when running Ubuntu netbook 10.10. Initially it boots fine but Ethernet is very random on whether it will work or not. Repeated attempts to connect eventually work, and when it does, it is reliable. However, after installing all the packages for setting up a dev environment, the board will hang exactly the same. A reboot is required after the packages are installed, then it hangs. I was able to get the message "X-Loader hangs" at the last attempt.

Build assembler errors on Beagleboard ALIP
I am seeing the following when trying to build pulseaudio on a Beagleboard
running a current ALIP daily:
...
CC libpulsecore_1.0_la-svolume_
arm.lo
{standard input}: Assembler messages:
{standard input}:82: Error: thumb conditional instruction should be in IT
block -- `addcs r0,r8'
{standard input}:83: Error: thumb conditional instruction should be in IT
block -- `movcs r6,r0'
{standard input}:98: Error: thumb conditional instruction should be in IT
block -- `addcs r0,r8'
{standard input}:99: Error: thumb conditional instruction should be in IT

block -- `addcs r0,r8'
{standard input}:120: Error: thumb conditional instruction should be in IT
block -- `movcs r6,r0'
...
I am using the normal pulseaudio build (bootstrap.sh, configure, make). The
build worked fine on a Pandaboard with Ubuntu 10.10. It looks like something
is not being detected correctly via bootstrap/configure on ALIP.
I have searched and seen commits in archive for adding "-Wa,
-mimplicit-it=thumb". I have added this to CFLAGS without success.
Anyone else seen any thing like this? Any thoughts on what else I could try?

Re: Build assembler errors on Beagleboard ALIP
Thanks Sachin, actually, no, it is from pulsecore/svolume_arm.c,
unfortunately arm assembler isn't my specialty (yet).
Ubuntu gets around this by building with -mimplicit-it=thumb. Since I have
temporarily given up on the panda (re: 708883), I now have the code working
now on beagle using this method, although I agree with Loic that it should
be fixed.
Once I get some of the arm buffer cpu wakes experimentation done and
published, I'll return to this.

PulseAudio buffer size comparison
Attached is a pdf with all the results of the buffer size testing on the Beagle C4 and Panda. I think this pretty much conclusively shows that increasing the buffer size when using timer based scheduling results in no improvement in cpu wakes per second. I also went back and tested alsa 1.0.24 in the audio stack to enable the recently added check for period disable. I appears that the beagle and panda do not have support, or it is not yet enabled in the driver. Does anyone know if these boards have the ability to turn off period wakes for the sound companion chips?
