Subject: [MPlayer-dev-eng] mga_vid.c smp problem
Hi.
./configure --enable-gui --enable-menu --enable-mga --enable-xmga
--with-reallibdir=/usr/lib/win32 --with-xanimlibdir=/usr/lib/win32
I use gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
I use FC3 with kernel 2.6.10-1.770_FC3smp. I dont have smp but got a HT
processor so thats the reason that I use smp.
mga-vid-2.6.10-2005-01-11.tar.gz wont build on my smp box :(

However, mga-vid-2.6.11-2005-03-06.tar.gz will build just fine. But later it
wont work, probably because its not the right kernel :)
I have tried to rewrite the Makefile and link files where it expect them to be.
Like in /lib/modules/2.6.10-1.770_FC3smp/build/include/asm I tried

Actualy mga-vid-2.6.11-2005-03-06 should work with .10 kernels too, as
the only changes were either clean ups or removal of deprecated functions.

lrwxrwxrwx 1 root 26 Mar 31 06:57 mach_apicdef.h ->
mach-bigsmp/mach_apicdef.h
lrwxrwxrwx 1 root 25 Mar 31 06:58 mach_mpspec.h ->
mach-bigsmp/mach_mpspec.h
but it didnt help either :(

I'd guess that your kernel isn't correctly configured.

Help?

Try a vanilla kernel from kernel.org and tell me the results.

Please note, that i don't have the time to support non-vanilla
kernels as i already lack the time to fully support the mainline.

Please also note that there is a mplayer-matrox mailinglist
for anything related to mga_vid, you should subscripe and
send any further mails there.

Should it be a files there? mga_vid for 2.6.11 compiles without problem and
I didnt put any file there when I compiled mga_vid-2.6.11.

Could be that the makefile of the .10 version caused this
(yes, it was broken)

Yes, most likely.

Ok. It doesnt... Im not in front of that computer now so I cant see the
error msg.

Send that message with a complete description of the error behavior

A friend that also got a G400 told me that he had gotten it to work in
2.6.10. He didnt have the orginal archive and didnt remember where he got
it from, but he did a tar.gz for me. That version worked DIRECTLY! I was so
suprised. TV-out worked aswell.

[***@flashdance dev]# ll mga*
crw-rw---- 1 root 83, 0 Apr 8 22:08 mga_vid

It uses 83 as major number.

It isnt your version and it appears that it isnt this version
http://www.linuxops.net/~pw/mga_vid/ either because I download it and
it didnt compile.

He also said that this version didnt work on 2.6.11 which he was running
now so I gave him the link for your version and that worked on 2.6.11.
Probably (but not certain) your version will work on 2.6.11 SMP also.

Since I avoid to switch kernel (new kernel = new possible problems) if I
can I'll stick to this version until I really need to upgrade.

This is the contens of his tar.gz if anyone knows where it cames from:

I did that, they told me to mail you directly instead.

Nope, you used mplayer-dev-eng, that's a different mailinglist

Oh, sorry.

Yes, we recently got 83 as official major number and thus
had to switch. My .11 version does also use this.
All prior versions used 178
These look like the contents of the mplayer main/driver dir,
ie it seems like a patched version of it. Most probably

Oki.

[sam chan]

all,

i'm having flickerling lines on the right portion of
videos using mplayer thru mga_vid. it appears on different
formats. any ideas what is causing this? and how to
fix?

i don't have the problem using a different video output
(eg, vo=x11 or vo=xv).


thanks,
sam

It seems to be a bandwidth issue. Running X in 16 bit colour fixed
it for me.

I assume you are using a G200 with a "high" resolution,
then you have hit the limit of the BES. Either lower
the resolution, the horizontal frequency.

If it's not that, then you have to tell us more.

I get the same problem with G400MAX and 1792x1344x32 @ 75 Hz. I as told
some year ago that it was because the same reason as above.

[sam chan]

i can fix the problem either by setting a lower
resolution(1280x1024) or lowering the color depth
to 16.

this is a G400, by the way.

thanks.

*** UPDATE ***
The Mplayer developer has put out his own 2.6 port for mga_vid, which you can find at
http://attila.kinali.ch/mga/

This means there is no reason anymore to maintain this patch, so I won't. Please convert to using Attila's driver
instead of this one.
**************

So am I surprised that what worked for 2.6.10 doesn't work for 2.6.11?
No, I'm not as I stopped trying to keep up with the kernel changes
because Attila kindly took over the flag from me. If there is demand I
might maintain my version too, but that seems a bit of a duplication of
effort. Besides, it's not that much different from Attila's anyway.

Anyway, I'm going to have a whack at Attila's driver now as I switched
to 2.6.11 myself. See if it builds and works (I trust it will). If I'm
really bored, I'll try on my SMP box too :-)

Ferdinand O. Tempel
