matroxfb and 2.6.0-test2

matroxfb and 2.6.0-test2

[Frédéric L. W. Meunier]

The card is a Matrox Millenium G400 M4A32DG (single head).

2.6.0-test2 is the first 2.5.x I try, so I may be missing
something.

During make modules_install I noticed the following warning
(yes, I installed the latest module-init-tools):

if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.6.0-test2; fi
WARNING: /lib/modules/2.6.0-test2/kernel/drivers/video/matrox/matroxfb_crtc2.ko
needs unknown symbol matroxfb_enable_irq

I don't know if it's serious but then I rebooted from 2.4.21.

My init script contains

if lspci | grep -q 'MGA G400'; then
modprobe matroxfb_base
fi

and /etc/modprobe.conf options matroxfb_base vesa=440

After it the screen became corrupted with a dump of my last
shutdown. All commands still worked. I don't use fbset at all.
The logs don't have anything about matroxfb.

With 2.4.21 I get

Yes, I'll fix that. Arpi pointed that out to me when I backported
IRQ support to the 2.4.x. Just adding

EXPORT_SYMBOL(matroxfb_enable_irq);

at the end of drivers/video/matrox/matroxfb_base.c does the trick.

Try building matroxfb into the kernel. I believe that current VT system
does not take over console anymore if fbdev is loaded after fbcon, but
I never tested it myself.

Thanks. It worked (and I don't see any screen corruption).

Maybe I'm missing something, but is there anything wrong with
video=matroxfb:vesa:0x1B5 ? I got

Kernel command line: BOOT_IMAGE=3 root=307 acpi=off noapic video=matroxfb:vesa:0x1B5

and the monitor was black on part (a few cm) of the left side,
although everything was on the screen.

It worked fine with what I'm used to, 1024x768x32bpp;

Kernel command line: BOOT_IMAGE=3 root=307 acpi=off noapic video=matroxfb:vesa:0x1B8

and with the default:

BTW, I'm pretty syre I only got the following warning compiling
as a module (GCC 2.95.4):

I have an old matrox millenium 1 card.  does the matrox fb support this
card?  All I got was a blank screen.  fbcon and matroxfb with support for
I/II cards compiled in.  When I had vga16 compiled in as well, I would get the
console if I switched to vt2 and back to vt1.

I don't know if there's an IRQ being assigned to the card.

Correct. You need run con2fb if you load a fbdev driver after fbcon.c. 
This maps the framebuffer to the console.

What is on screen? Correct 640x480 picture?

Do you use matroxfb-2.5.72 patch or not? You are not supposed to use
fbset on stock 2.6.x kernel (without patch above), you should use
stty cols & rows to set videomode under 2.6.x kernels (you can try
using fbset -pixclock to set refresh, but never change picture size
through fbset).

First: 2.6.0-test2 does not come up with a blank screen.
Second: using fbset to set another mode (1024x768-60) causes a blank screen
but changing vts gives me the screen back.  It must be using a different
frequency since the screen is not inthe same place.  setting 680x480-60
makes it look right again.  The actual resolution doesn't appear to change. 
If I have enough written to the screen after issueing the 1024x768, the text
becomes garbled (old text seems to interlace into current.

Here Athlon XP 1700+, XFree86 4.3.0.1, IceWM 1.2.9. Clocks with
seconds on both window manager and screen, but it happens
without them and if I just startx and close it. As I reported
it doesn't happen with your patch, but I may be seeing the
other "problem" you mentioned at
http://marc.theaimsgroup.com/?l=3Dlinux-kernel&m=3D105908939813118&w=3D2

"BTW, with my patch accented characters works correctly only on
VT1.  I'm not sure how it behaves on Linus tree..."

Same behavior without your patch. Here I use setfont
lat1-16.psfu in my init scripts. All accents work on the first
console but on the others most miss them for capitals.

I don't have two with your patch.

2 other problems went away with your patch. When I reported no
screen corruption I was wrong since it messed everything
returning from XFree86, including getting a dump of a Windows
reboot. The other is the boot logo, which now appears.

Yes.  This caused a permenant black screen.  fbset did not give me anything
usable.  Monitor did not go into powersave.

I did, but that caused it to give a blank screen until I changed VTs.
I removed both vesafb and vga16 and recompiled to achive the result I stated
above.

I'll try 2.6.0-test2 later on today.  I did not do a make clean between
compiles.  When I compile test2, it will be clean, I never patch dirty
trees.

I assume that machine is otherwise OK. Can you capture 'dmesg' from
such boot and post them?

Yes, it supports Millennium1 too. Are you sure that you built fbcon
support into the kernel? And that you have only one fbdev, matroxfb?
