[Q] is framebuffer console code in 2.5.4x functional ?

Hi all,

I'm trying to resurrect SGI Visws support in 2.5 kernels and have two
problems: frambuffer console doesn't show anything and legacy device 
interrupts not working. It's difficult to debug second problem without
console :(

Framebuffer driver sets needed video mode (checked with monitor's ods)
and starts display dma engine successfuly (i can even draw lines on the
screen using memset()'s). But the beautifull linux logo doesn't apear and
console doesn't show a single pixel.

Simple(silly) questions:
	- is 2.5.4x framebuffer console code really functional ?
	- if yes, where to start debugging this issue ?

Best regards.

So the driver is functional. I assume also a cat /dev/urandom > /dev/fb 
works as well.

Fixed in the fbdev BK tree.

:-( Can you post your .config file.

If the driver has been ported to the new api then yes it works. I did port 
the SGIVW driver some time ago bit didn't have the hardware to test it. 
I will be posting a new fbdev patch today against 2.5.48 today. Giev it a 
try.

Yes, it fills screen with fancy patterns.

I did some changes to sgivwfb.c to make it compilable, patch attached.
Can you take a look at it ?

Didn't see proposed fbdev patch yet :(

    Sorry about that. You are not the only one that has asked me. Also I 
keep getting lots of error reports about drivers being broken. The problem 
is having enough time. For example I haven't found the time to create this 
patch. This brings up a serious point which I have been wrestling with. The 
framebuffer layer has been broken for a long time durning the 2.5.X cycle. 
The problem is both maintainers of this subsystem, Geert and I, both have 
very little time to work on it. For both of us we don't work on the 
framebuffer code for a living. I work with wireless networking cards. I 
work 8 hours a day on networking code and travel 3 hours total every day 
to work. Including eating a sleeping and I have at most 1 to 2 hours a day 
to work on the framebuffer stuff. Weekends I have to do other survial 
things like buy food. So the framebuffer developement has gone at a 
snail pace and will continue to do so unless things change. I estimate 
about 20+ more versions before the framebuffer layer properly works. 
    It pains me that this is happening. I really enjoy working on the 
framebuffer and console layer. So I have been thinking about what to 
do ? One which is the most likely is to step down from maintaintership 
and hope someone else who can devote there full time and energy to it 
can take over. Will someone else take over? I seriously doubt it. We all 
have to make a living and that means working on things the linux industry 
cares about which is only server stuff. So I except the framebuffer layer 
will go into serious code decay. So the best situtation which I except to 
happen is that I finish as much as I can for the fbdev layer and then 
step down. 
    I have tried to look for work locallly (can't really affored to move 
cross country very few years) relating to the framebuffer layer. In my 
search I only found one company that seemed interested in this developement, 
strangeberry (http://www.strangeberry.com). I sent them my resume but 
never heard from them. As for funding I serious doubt that would happen 
since it isn't server related. The reality is for proper maintiance of any 
subsystem you need people hired to solely work to keep it going. 
Unfortunely the framebuffer layer is one of those few ones that doesn't 
have that.

Forgot to mention, I've seen message:
	fbcon_setup: No support for fontwidth 8
in /var/log/dmesg. 

I found this printk() in fbcon_setup(), but i can't even imagine 
why it happens.

Sorry for not providing full info, but when i wrote first letter 
my head was full of gory thoughts about visws legacy irq handling :(
I can post complete log tomorrow.

I understand this situation perfectly, looks like it's almost common for
developers working in "not so importatnt for servers" subsystems :(

Perfect. I found the problem and I'm about to commit to BK. I posted the 
latest patch against 2.5.49 at

http://phoenix.infradead.org/~jsimmons/fbdev.diff.gz

:-( Some day that attitude will change.

P.S

    Several drivers have been ported but not all. NVIDIA is still broken 
but I will fix it tonight.

Add these file into /home/jsimmons/dontdiff:
	vmlinux.lds.s
	gen_init_cpio
	initramfs_data.cpio.gz

I'll test the patch this eveninig.

I tried this patch, but it crashed during boot.

I have a 
01:00.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro AGP
1X/2X (rev 5c)

and use this in lilo.conf:
image=/boot/2.5.49fb
        label=2.5.49fb
        append="video=atyfb:1280x1024-16@85"

This got me a 160x64 framebuffer with yellow text on
blue background.  Nice, but only got about 10 lines before
the kernel hung. The disk light got stuck on and there were
no response to things like sysrq.  
The few lines displayed was about the fb, drm, and finally
the 3com network adapter.  Then nothing more.

2.5.49 without this patch works.  I use devfs & preempt,
the machine is UP and I use gcc-2.95.4 for compiling.

Hm. Are you using a PPC or ix86 box? I will test this tonight.

No.  The machine froze solid. No oops, no sysrq.
The reset button worked.

i386.  Specifically, a pentium II, compiled for pentium II.

Perhaps. It didn't look like it ended at the bottom of the
screen, but then it might have been panning at the wrong moment.

VESA fbdev did this to me. I have no trouble with neofb. Strange???
I will track it down tonight.

Hm. I have that same card and a similar machine.

I have a MDA monitor and card. So I can setup mdacon and turn on 
debugging in fbcon and trace threw it.

    aty128fb works for me here with:

01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS

    Thank you!

    There are a few glitches, but I've been unable to pin down
anything serious as the fbdev patch's fault.  I'm still playing with
things (like Antonio Daplas' patches).  I'll give a more full report
later.

    FWIW, the fbdev patch applies with a few minor offsets to 2.5.50
except for the attached patch, which I extracted from bk.  So if you
apply this patch in *reverse* to a clean 2.5.50 tree, the fbdev patch
should then apply okay (patch complained about a reversed hunk in
fbcon.c, but it should be harmless, I think.)

Great. I made more inprovements with my latest patch. Give it a try.

I just intergrated a bunch of his work. The subsystem is starting to 
really take shape.

I noticed. My new patch fixes that.
