anyone still using a G200

[Attila Kinali]

Moin,

Is anyone still using a G200 and could tell me whether
it is still working with current mga_vid for 2.6 and
MPlayer svn?

I hit a bug, but i cannot tell whether it's due
to my strange setup (ie the accessed card is not
fully initialized) or something in MPlayer that's
going wrong.

Thanks in advance

I have following matrox cards :
- g200
- g400 single head
- g450
- g550

Will test soon if current code works with g200.

Driver loads ...

... but does not work.

Tested with kernel 2.6.16 & MPlayer 1.0pre8 and mga_vid_test .

In both cases it only displays a green square with different colored
patterns in it (green, light green, magenta).

Any ideas?

I assume you have a framebuffer or X running on
that card. Otherwise you hit the same problem
as i do (not fully initialized card).

That sounds like that the colour planes are not correctly
converted. G200 does not use planar colour planes like
most other cards, but has Y-U-V interleaved.

How true... :( I installed xorg onto the machine, now everything works
fine. Sorry for the false alarm.

ps: I thought about adding a README.udev to the svn; describing the
setup of udev.rules. what is your opinion about this?

No problem. Thanks for testing.

Go ahead.

BTW: While we are at udev. I'm currently trying to figure
out how i can tell udev that
1) it should create me a mga_vidXX file for every
card i have in the system
and
2) make mga_vid a symlink to mga_vid1

Unfortunately, i'm looking the wrong way and cannot figure
it out. Any hints?

Something like the following should (but it does currently not) work :

KERNEL=="mga_vid[0-9]*", NAME="mga_vid/%n", SYMLINK="mga_vid%n", MODE="0660", GROUP="video"

How do you want to use multiple cards? Current driver has the minor
number hard-coded :

1141: mga_cdev_handle = MKDEV(major,0);
1146: class_device_create(mga_vid_class, NULL, MKDEV (mga_vid_major, 0), NULL, "mga_vid");
1198: class_device_destroy(mga_vid_class, MKDEV(mga_vid_major, 0));

My fault...

Can you try the following patch (I only have agp ones, and so cannot put
multiple cards into my computer) ...

And use something like this in /etc/udev/rules.d/mga_vid.rules :

This will create :

/dev/mga_vid/0
/dev/mga_vid0 -> /dev/mga_vid/0

And set proper permissions on /dev/mga_vid/0 .
