Driver Support for VIA VT1632A Video Card

Post#1 by MasterSplinter » 13 May 2011, 19:02

Hello,

I'm trying to get dual monitor support for my WYSE Thin Clinet V90L (800Mhz 512Mb RAM / 512Mb Flash HDD) running on 32-bit V1.0 RC1.

The video card is a VIA VT1632A.
ftp://ftp.vtbridge.org/Docs/Video/DVI_L ... 0_CCPL.pdf

It was suggested that this code could help me create a driver, but, I don't know how to apply it.
http://lxr.free-electrons.com/source/dr ... /via/dvi.c


Command: lsmod

Code: Select all

This is part of dvi.c

Code: Select all

 21 #include <linux/via-core.h>
 22 #include <linux/via_i2c.h>
 23 #include "global.h"
 24 
 25 static void tmds_register_write(int index, u8 data);
 26 static int tmds_register_read(int index);
 27 static int tmds_register_read_bytes(int index, u8 *buff, int buff_len);
 28 static void __devinit dvi_get_panel_size_from_DDCv1(
 29         struct tmds_chip_information *tmds_chip,
 30         struct tmds_setting_information *tmds_setting);
 31 static void __devinit dvi_get_panel_size_from_DDCv2(
 32         struct tmds_chip_information *tmds_chip,
 33         struct tmds_setting_information *tmds_setting);
 34 static int viafb_dvi_query_EDID(void);
Please cut all numbers example:

Code: Select all

#include <linux/via-core.h>
#include <linux/via_i2c.h>
#include "global.h"

static void tmds_register_write(int index, u8 data);
static int tmds_register_read(int index);
and put code to pastebin.com or all files to mediafire.com, and find files"via-core.h, via_i2c.h" is needed.

Perhaps try building this driver. I've not tested it.

I found some VIA drivers at slax.org, and converted one to a porteus module:

http://www.mediafire.com/?gjg7eq1jrto6to9

That appears to be the one that I was trying to compile. Try downloading that, put it in /porteus/modules, and see if it helps out. A couple others you might try are linked at the end of this thread:

Please take a look at our online documentation, here. Suggestions are welcome!

Thank you, everyone, for suggesting ideas for this thread. It is very much appreciated.
There is a lot on my plate here, for things to try...and being a newb... it's probably gonna be a slow process for me.

At this link, I did find some progress. The OpenChrome drivers enabled the second monitor, but they were mirroring. The Configure Display options didn't offer or suggest that it could see both displays:

Thank you, :) I booted into text mode and did as you said. This wasn't successful. It only allowed one display to show, and the Configure Display options didn't show any sign of multiple displays.

MasterSplinter, ok. I have a new suggestion.

1. download these modules:
crippled_sources-porteus-v1.0_rc1-x86.xzm
kernel_headers-porteus-v1_rc1-x86.xzm
apr 1.4.2 i486 2.xzm
apr util 1.3.10 i486 1.xzm
subversion 1.6.16 i486 1.xzm

2. Then copy these modules to /porteus/modules/

3. Boot up Porteus in Text mode and type these commands:

Code: Select all

svn checkout http://svn.openchrome.org/svn/trunk openchrome
cd openchrome*
./autogen.sh --prefix=/usr --enable-debug --enable-xv-debug
make
make install
reboot
Probably need to tweak a /etc/X11/xorg.conf
4. Edit /etc/X11/xorg.conf and change device driver to openchrome. You may want to make a backup first.
The "Device" section should include the "openchrome" driver:

Code: Select all

Section "Device"
        Identifier      "Configured Video Device"
        Driver          "openchrome"
EndSection
Save the file.

I booted into text mode after the 'reboot' command you gave. I went to /porteus/changes/etc/X11 and tried to edit the xorg.conf file... "edit" wasn't working and I didn't remember the command to edit text files from a command prompt... being a lil lazy, I typed reboot, and went into KDE mode instead. I did notice that the auto-config for video is executed every time KDE is launched from the GRUB. I'm not sure if that negatively effects the xorg.conf for my efforts.

The original xorg.conf (/porteus/changes/etc/X11) after booting into KDE looks like this:

As it stands now, there is just one display enabled and the display configuration doesn't suggest there is another display to work with.

Posted after 17 minutes 22 seconds:
UPDATE:

It seems that after each reboot, the auto configuration for video over writes my changes to my xorg.conf to:

Code: Select all

Section "Device"
Identifier  "Card0"
Driver      "openchrome"
BusID       "PCI:1:0:0"
EndSection 
I'll need to figure out how to turn that off.

MasterSplinter, hm... damn :wall:
You can try to convert two deb packages with driver for via from debian repo in xzm format:
xserver-xorg-video-via_0.2.904+svn842-2_i386.deb
xserver-xorg-video-openchrome_0.2.904+svn842-2_i386.deb
and then try to copy these modules to /porteus/modules/

Re: Driver Support for VIA VT1632A Video Card

Post#10 by Ahau » 24 May 2011, 15:38

I prefer to use 'mcedit' to edit text files from the command line. Just use 'mcedit /etc/X11/xorg.conf'

If you have a xorg.conf that you want to continue using (rather than having porteus make a new one on reboot), then you need to store your new xorg.conf with the changes= cheatcode, put it in your rootcopy (/porteus/rootcopy/etc/X11/xorg.conf) or build a module for it:

mkdir p /tmp/newmodule/etc/X11/
cp xorg.conf /tmp/newmodule/etc/X11/
dir2xzm /tmp/newmodule /tmp/customxorg.xzm
cp /tmp/customxorg.xzm /mnt/sdXN/porteus/modules

AND

remove xconf from your APPEND line:

autoexec=xconf; telinit~4 => autoexec=telinit~4

autoexecuting xconf is what tells porteus to configure xorg while it's booting up.
Please take a look at our online documentation, here. Suggestions are welcome!

You can try to convert two deb packages with driver for via from debian repo in xzm format:
xserver-xorg-video-via_0.2.904+svn842-2_i386.deb
xserver-xorg-video-openchrome_0.2.904+svn842-2_i386.deb
and then try to copy these modules to /porteus/modules/
The very first thing I tried was to stop xconf from executing at startup (/boot/porteus.cfg editing KDE only), that way I can observe step-by-step the results of each change. That was successful. The next thing I did was re-do Blaze's steps 1 - 4 (just in-case xorg.conf got modified during that process)...which it apparently didn't. I placed a copy of xorg.conf in the appropriate rootcopy sub-folder. At least now, I am satisfied that I have more control.

With some help, I was able to convert those two .deb files into .xzm files. I had been accustomed to right-clicking on non-porteus packages and left-clicking on "Convert deb to porteus...". The error I got was: "Could not find the program '(/opt/porteus-scripts/deb2sq4'".

I was then instructed to try:

Code: Select all

deb2xzm xserver-xorg-video-openchrome_0.2.904+svn842-2_i386.deb
...which worked like a charm.

I placed both modules in /porteus/modules/ right next to the other ones and rebooted:

/porteus/modules/:
crippled_sources-porteus-v1.0_rc1-x86.xzm
kernel_headers-porteus-v1_rc1-x86.xzm
apr 1.4.2 i486 2.xzm
apr util 1.3.10 i486 1.xzm
subversion 1.6.16 i486 1.xzm
xserver-xorg-video-openchrome_0.2.904+svn842-2_i386.xzm
xserver-xorg-video-via_0.2.904+svn842-2_i386.zxm

Choosing KDE, it booted into a text mode. Startx wouldn't work, so I did a xconf. Startx worked then. I was pleased to see that both monitors were now enabled, but, mirrored, and the display configuration didn't detect multi-displays.

(changed permissions on all .xzm files to -rwxrwxrwx) The earlier 5 modules were already -rwx.

I then tried to remove all modules except (below) and rebooted:
xserver-xorg-video-openchrome_0.2.904+svn842-2_i386.xzm
xserver-xorg-video-via_0.2.904+svn842-2_i386.zxm

Same results. I then renamed my porteus/changes to changes.old2 and rebooted.

Same results. I did discover, however, that I had an issue deleting any of my previous "changes" folders with the error: Could not make folder //.Trash-0/files/changes.old/.wh..wh.plnk.

A Note:

Before I looked into Porteus RC1, I was using Slax 6.1.2... I noticed that Slax detected that there was more than one display in the Display Configuration (an extra tab called Multiple Monitors) ... although it failed to utilize them... among other things, it would only let me have a refresh rate of 60Hz. @ 1600x1050... I think Slax just needed to use some of the drivers you guys have been suggesting.

I am booted into Slax 6.1.2 (at this moment)... I am wondering if the Display Configuration application is different from what Porteus us currently using, how to compare, and use... if possible.

Porteus x32 using the KDE 3.5.12 Trinity , and Slax 6.1.2 using KDE 3.5.10 , it is not the same version and not the same config "synthax".

Blaze gave me these links to look at to aid me in dual monitors:

I would also like to add these links to my thread for xrandr... a possible alternative to getting dual monitors setup.

Thank you :D

I also want to post this link, which may or may not work in Porteus....lxrandr: it is a small gui for controlling xrandr.
