Guide to Get the Best Performace from the GMA 500

[jbernardo]

Good luck getting any answer from Intel apart from "we support various distributions other than meego" and pointing you back to our wiki and this thread.
Anyway, I'll help in whatever way I can. If they can give us a version of EMGD with 2D and kernel drivers opened (including their patches to standard libraries like libGL and libva), and keep only the 3D driver binary, we might be able to switch out of psb for good. If they keep this all binary crap, our best bet is still getting psb fixed. Maybe if we started a bounty for a programmer to fix psb support?

Hi, Luca !

It sounds freakin' great !!
In case on my proposed Natty, still has some unsolved dependencies so I couldn't test yet with EMGD...sorry.
then it seems Unity-Qt of 2D-team/PPA would be ported into "Unity-2D" mainstream. in fact, Unity-2D had already been prepared in main repos.
I also concerned the state of "Unity-3D"... I think it might be rebuilt for Wayland, don't you ? it seems to be natural.

And may I introduce our situation in EMGD to embedded forum in Intel ? I want their loadmaps and let us know some features.

• compatibility in features of Xorg 1.10.
• compatibility in DRM/KMS for after Natty.
• posibility in "Opened Sources" of native EGL and/or OpenGLES for Wayland.
• newer libva without libdrm.
• and more.

If yes, I would post in a few days A.S.A.P. Maybe we might need some help from X-edgers team and jbernardo when we ask our requirements to Intel.

Regards.

Yep, Unity 2D is now in main repo for natty, ppa is still valid for maverick.
Unity 3D on Nvidia with latest updates is freaking impressive :O .. hope to have it working one day on gma500.. lol

If you have time write to Intel, maybe you're luckier than us

Thanks jbernardo and luca !

I would do that A.S.A.P. then I'm preparing for sort out my logs and arrange them in order...
I hope we could "Open the Door" !!

Cheers.

I've copied updated poulsbo-config package for maverick in ppa:gma500/fix from my ppa (native VT and plymouth, KMS and suspend fixes)
Test it carefully! Maybe it is better to uninstall current version before using this one because of changes.

Hi, all Natties.

[off-topic]
I've partially tested "Unity-2D" on proposed Natty Alpha-1 with EMGD.

Natty still has unmet dependencies between Unity-2D and 3D especially libraries called "libunity0", "libinidicator1" and more, but newest Natty had already moved to libinidicator2. so I only use Unity-2D-launcher (also unity-2d-panel works, maybe) with composited-metacity and "Wingpanel". Wingpanel only states pre-pre-pre-alpha release, but stable, lightweight and awesome for me !!

If you knew any newer stuffs for 2D Desktop matched for performance of GMA500, let me know.

Would you kick gnome-mplayer from terminal like this:

gnome-mplayer -v /path/to/movie/file

then some messages would remained in terminal, so you copy&paste all of them to http://paste.ubuntu.com/ and attach here. I need your logs!

Thanks.

Hi Tista.
Here's my logs:
1. This is what I have in terminal
http://paste.ubuntu.com/554403/
2. and this is actual verbous output which I redirected to file:
http://paste.ubuntu.com/554401/

What I did here:
1. Ran gnome-mplayer with vaapi output type.
2. Tried a couple of times to change audio stream to needed one;
3. Changed output type to gl.

Hi, godfazr.

Thanks for your post.
so I could picked these messages up:

AO: [pulse] 48000Hz 2ch s16le (2 bytes per sample)
ERROR: [ac3 @ 0x4dec860]frame CRC mismatch
Selected audio codec: [ffac3] afm: ffmpeg (FFmpeg AC-3)
ERROR: [ac3 @ 0x4dec860]frame sync error

then have you tested "ALSA" ?
usually pulseaudio would eat more resoures than alsa.
or tried "-afm faad" ?
and you're right, whenever playing avi we should set cache to zero.
I also know who re-installs pulseaudio a couple of times because of some troubles in audio playback on HDA-Intel.

finally if you knew similar videos exist on the web, I could check on my environment. and give me a bit more time to read whole things up.

Cheers.

sorry for my post twice ..

[godfazr]

then have you tested "ALSA" ?

doesn't make any difference

or tried "-afm faad" ?

is this param of gnome-mplayer? coz it tells me that -afm is unknown parameter...

p.s. this forum engine is freaking slow in submitting posts, so sometimes you just need to wait before refreshing page/clicking 'Submit post' button again to not make doublepost.

Hello everybody!

Happy New Year!

I was wondering about the new EMGD release. Today I went to http://edc.intel.com/Software/Downloads/EMGD/#download to see if EMGD was released. I was surprised to see that the new date was the 15th of January 2011. I downloaded it but it was the 1.5 - 1742 version (the same as the previous release)... Is there a new release today or am I wrong?
