US15W card Driver install problem

[Daniel]

My configuration:
Board : intel Atom Z510 1.1 Ghz + US15W (menlow)
Screen 800x600x24bits on LVDS port
512Mo DDR2
4Go Nand Flash (on USB).

I've got the Fedora11 and Meego1 drivers : X1.6.4 or 1.7.99.
With xorg.conf configuration (joined).

Using install (original joined) scripts (adapted for TCL), with both drivers (and updated xorg.conf) X doesn't start
(screen not found : Xorg.0.log)

I've got souces (see install.zip for script) ... but with adapted script to TCL, i've got tar errors (make directory) ... and the make cmd fail!

1: is the xorg.conf update ok for TCL ?
2: what is this tar error ? (sure, with error, i can't do make)
3: i've got the intel sources, but 32Mb. if somebody want have a look, i can put it on an ftp server.
4: if any information is missing, please ask me!

Thanks
Daniel.

PS: i can't join files ... i will try again after post : Impossible.

It seems this US15W is an PowerVR chip, licensed by Intel as GMA 500. Following these instructions http://www.nanoant.com/linux/compiling-kernel-iegd-10x-module-for-any-linux-distribution the biggest problem is the kernel module. An install script will not work because you have to build this one yourself ;-) Binaries/sources for the intel IEGD driver are available here http://edc.intel.com/Software/Downloads/IEGD/Default.aspx?id=1013 in version 10.4.  However... no guarantee it will work at all. I'll take a look at the kernel module.

[edit]
Intel "source" only contains precompiled binary drivers for Xorg xserver 1.6.4, which makes it incompatible to Xorg-7.5 with xserver 1.7.7. I read some people are backporting xserver 1.6 to Xorg-7.5 to be able to use the binaries. Kernel module iegd_mod.ko compiles and can be added to graphics-2.6.33.3-tinycore...

Thanks!
I will look to your links!


I've put accessible drivers and configuration  ... follow links :
http://dl.free.fr/rUyX9Gkm6  for install (in driver package)
http://dl.free.fr/r3WstfjHf full driver package (with sources)

If all you need is 800x600x24 then it might be possible that Xfbdev could work directly - without any need of 915resolution and/or uvesafb, under the condition that you can get that mode at boot time.

[gutmensch]

FWIW I uploaded an iegd-emgd-2.6.33.3-tinycore.tcz extension, which contains modules for Intel embedded chips: iegd_mod.ko and emgd.ko. For accelerated graphics and some binary form Xorg driver from Intel you will at least need this extension. If the binaries from Intel are working with either Xorg-7.4 (1.6) or Xorg-7.5 (1.7) from our repository I'm not able to say.

[Daniel]

KO test with iegd-emgd-2.6.33.3-tinycore.tcz + Xorg7.5.tcz and intel drivers compiled for X 1.7.3.

Here are dmesg and Xorg.0.log with intel xorg.conf configuration

And xorg.conf custom

The emgd extension should depend on the graphics- one, it seems.

[Daniel]

What does that means ?

What have i to do to have a correct configured xorg.conf ?
Or does i need correct drivers ?

thanks
Daniel.

This graphic card is on 4000 installed machines (ubuntu 8.04) !

We have planed when it run's to update them with TCL.
And others 300 (actual park) machines ... (actually under ubuntu 10.04).

The production is continuing. (around 1000 per year).

Until the dep file is fixed, load the graphics-2.6.33.3-tinycore.tcz extension also.

[Daniel]

next test:

kernel command line : ... vga=789 text consoleblank=0
in order to start X manualy (because of black screen with no action possible : (with xorg.conf.vesa copied on xorg.conf)).

Here is the dmesg results

[gutmensch]

dep file fixed - like curaga suggested you also need graphics-2.6.33.3-tinycore.tcz extension (not either this one or iegd-emgd, you need both).

then try this one again:

iegd-emgd-2.6.33.3-tinycore.tcz + Xorg7.5.tcz and intel drivers compiled for X 1.7.3 ( + graphics-2.6.33.3-tinycore)

it looks quite good he just can't load the emgd kernel module because of the missing drm modules from graphics-2.6.33.3-tinycore!

[Daniel]

I've done test with this configuration yesterday.

But i have black screen locked, with no possibility to go to console debug
I can't have a look to xorg.0.log

Have i to modify xorg.conf ?

Daniel.

[Daniel]

I've generated a new intel driver : full generation is here http://dl.free.fr/getfile.pl?file=/kpUZo5Sa
In this file, for xorg 1.7.3, there is an install script. But is it ok for TCL ?


With iedg-emgd ... + Xorg7.5 + graphics- ... and the intel EMGD driver, i've got same results:
locked black screen!

How can i get xorg.0.log without terminal ?
Can this file generated on a fixed media ?

or ?

thanks
Daniel.

[gutmensch]

you should start an sshd server on the client and tail Xorg.0.log from another pc when starting X, this way Xorg will still hang up but you will have output. you can also debug X over ssh with the use of gdb ;-)
