Fedora Needs Your Help Hitting On GNOME Software Rendering

The Fedora developers have organized a test day where they're looking for users with either no Linux graphics driver support (or just troubled drivers) to try their systems with a new spin of Fedora 17 that's taking advantage of Gallium3D LLVMpipe-powered software rendering for the GNOME Shell.

If anyone want to help testing on our beloved gma500 this could be a good initiative.. unfortunately I'm not at home to test it.

The result of this testing day could be ported also on Ubuntu

Hi Tista,

just to double check, would the package work on 11.10 having installed the 3.3 Kernel?

Hi blugeco.

Yep, you're welcome to do double-check on my works...
And "Yes". I've done building tests on my VAIO P running Oneiric.

I have a Nokia Booklet 3G (GMA500), my plan would be to:

- install Oneiric
using poulsbo.asd=1 psb_gfx.asd=1 options at startup

- install kernel 3.3

- install EMGD 1.8 from the PPA

- apply the package
dpkg -i emgd-dkms_1.8.0.2032-0ubuntu2~kernel.3.3~ppa1_all.deb

- reboot

If having any questions for instruction of install, please visit our ppa page. I would suggest this commands:

sudo add-apt-repository ppa:gma500/emgd-1.8
sudo apt-get update
sudo apt-get install xorg-emgd emgd-dkms
sudo emgd-xorg-conf

dpkg -i emgd-dkms_1.8.0.2032-0ubuntu2~kernel.3.3~ppa1_all.deb

reboot

Would that make sense? Or it's maybe worth to try the EMGD 1.10?

Yeah exactly makes sense!
But umm... I don't know today which would be the better whether we should tackle to 1.10 or not... Because 1.10 has some issues on vaapi playback, so someone would like to rollback to 1.8 especially in the case using poulsbo machine as video player...
In opposite, kernel codes of 1.10 seems quite well than 1.8 obviously since 1.10 already had fbcon routines. If it had KMS codes, that would be perfect...

Thanks guys,

blugeco

I hope this patch could help you guys, too.
And you're welcome to post any issues on my patchworks. since now I'm thinking "2nd round" to polish it...

Cheers,
Tista

PS
Oh forgot to mention...
if you had experienced something like "build failure", please let me see your buildlog... and then you could find stock package in /var/cache/apt/archives, so dpkging might help you after rebooting with an older (stock) kernel in oneiric...

Hey Luca!

Oh what a nice thing comes up to us!!

I hope this could break the "Brickwall" of llvm performance...

Oh I gotta go dinner...
Ho una fame da lupo!
grrrrr....

LOL .. I'm stuck at work w/o my lappy to test llvm

happy dinna!

EMGD 1.10 does have KMS support (it was added along with the Wayland support), it just isn't turned on in the default configuration since it doesn't get used during the typical X-based operation. You'll need to flip on both the "kms" and the "init" bits in egd_drm/emgd/drm/user_config.c (which is basically the DRM driver's equivalent of xorg.conf).

Hey Matt!

Been a while...
So OK... well which did those values must be set as "boolean" or "int"?
Now I'm flipping them to "1" as boolean and building against 3.2 kernel...

Stay tuned..

Yes, setting them to "1" turns them on.

Note that you'll want to fill in your panel timing information (or specify that it should use EDID if you actually have an EDID-capable panel) in the user_config.c just like you would in xorg.conf since those panel timings will get used to generate the KMS mode list and setup the framebuffer console before X or Wayland start up.

Hi Matt,

Thanks in advance...
So now I've patched like this:
http://paste.ubuntu.com/905964/

And it could boot QUITE FASTER!! Wow!!
but unfortunately I had to keep my user-space configuration alive still... yeah if not, xorg didn't come up. My patch might need more fixes...

Finally I actually set VT number #7 as graphical splash (means plymouth), but somehow EMGD 1.10 seems to run on VT #8, haven't a clue.

Anyway really thanks again!! I would keep tracking some logs/issues down.
You are a real hero...

Hey all!
Great news for all of us:
http://www.phoronix.com/scan.php?pag...tem&px=MTA3ODU

Last November I mentioned the state of the open-source GMA500/Poulsbo DRM driver that's still basic and lacks 2D/3D acceleration support, but Intel's Alan Cox mentioned at that point that video acceleration might be possible on open-source.
...the DRM driver might be able to be worked up to handle video acceleration.

Hi blugeco.
Yep, you're welcome to do double-check on my works...

Hey guys,

I am afraid it didn't work ...

Just to summarize, I installed XUbuntu 11.10 on a Nokia Booklet 3G, then installed the Kernel 3.3 (3.3.0-030300-generic).
After restart, the system was working well, nice and snappy.

The I installed the EMGD 1.8 and applied the patch (following Tista's instructions),

sudo add-apt-repository ppa:gma500/emgd-1.8
sudo apt-get update
sudo apt-get install xorg-emgd emgd-dkms
sudo emgd-xorg-conf
sudo dpkg -i emgd-dkms_1.8.0.2032-0ubuntu2~kernel.3.3~ppa1_all.deb

I didn't have any error during the installation ... so I restarted thinking I finally got it right ... but at restart, the screen just went black ... nothing going on at all.

I was thinking to try these workaround

Also ... I can't find the post now but I think I read Plymouth was supposed to be uninstalled as well?

Any more suggestions?

Thanks for all your efforts,
