Why?  I don't want to live another release with the old, crappy console,
and you've been working on this during almost all of 2.4 now..

[BK console] console updates.

[James Simmons]

Hi folks!!!

   Along with the new fbdev api I also have rewritten the console layer.
The goals are:

1) The idea here was to move alot of the basic functionaly present in
   alot of low level drivers into the the higher layers thus making the
   low level drivers smaller and cleaner. A good example is using the
   /dev/fb interface to resize a VC. That is just plain dumb.

2) The second goal was to seperate out the terminal emulation to allow
   for a light weight printk. Also the idea was to make the VT console
   system modular. On embedded devices then we can insmod the VT
   console system. This is partially done.

3) Multi-desktop systems. Already done this. The current code in BK
   doesn't support this just yet as I have a few bug to beat out for
   single headed systems. It will take about one more week to get this
   ready.


I doubt this code will go into 2.5.X but it is avaiable for anyone to play
with it.

BTW I will make patches avaiable as soon as 2.5.45 comes out.

this is something i know several people are interested in. and it
does not touch core code to add, does it?

Yeah, of course ... his psychic power must be weakening, he

That's not a patch, it's a CVS tree. Just mail out a normal
patch, like everyone else.

Don't even bother posting to the list without a patch.  Saying you want

Okay. Here is the new console system. The patch is against 2.5.45.
Please note only vgacon has been fixed to work with this new api.

Just the VT console code. It does effect the console display drivers tho.

As far as I understand it, he just provided you a status report so that you
could see what's going on etc (especially relevant around the Oct-31 deadline),
and he fullfiled his promise and sent the patches as soon as 2.5.45 came out,
didn't he? So what's wrong?

Give my console diff a try.

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

Its against 2.5.45. It has 3 bugs I know of.

1) Switch back to X messes up the screen.

2) I had to disable the beeper. I have to think of a proper solution to
   that problem with Vojtech.

3) Software suspend is broken because the console has moved from the
   global int currcons to private struct vc_data to represent a VC.
   BTW what was the author of that code trying to do any ways?

It will. I'm waiting for the latest patches whcih do fix all those 
problems. As soon as I get them I will post a updated patch for the fbdev 
changes. 

2.5.54: radeonfb almost works

[Helge Hafting]

Radeonfb almost works now, but there are some problems
with setting (and resetting) the resolution.

I use a flat screen so anything except 1280x1024 is
hopeless to look at.  So I want that from the start.

Just booting with video=radeon gives me a 640x400
mode.  There's some initial garbage (looks like early boot
messages converted to graphichs at the wrong resolution)
on the screen, but that isn't a problem.  The low resolution
is, though.


I first tried "fbset 1280x1024-60", which changed
the resolution, but the console was still a
small 640x400 thing in the upper left corner of
the 1280x1024 display.  Not very useful.

So I tried booting with video=radeon:1280x1024-32@60
That gave me a blank screen, the monitor complained
about "no signal".

But I logged in blind, and ran fbset 1280x1024-60
again.  This gave me the console I want.
1280x1024 resolution, with 160x64 characters.

I could put fbset in a init script, but that is
fragile if I get some error before that init
script runs. I should really see the
console all the time.

Another problem comes up when running X.  Switching
from X to some virtual console always gives me the
"no signal" thing, and I have to type the fbset
command blind before the console becomes
visible.  Switching back to X is never a problem.

This is a UP machine, P4 processor, using preempt.
I use a radeon 7500 in an AGP slot.

640x480 is normal.

Because fbset is only useful for setting /dev/fb. You want to use stty
to set the resolution now. The advantage of this is we don't end up
with a console mode of 80 3/4 columns by 30 1/4 rows. 
Try

stty cols 160 rows 64 

assuming you are using 8x16 fonts.

Sounds like a monitor timings issue. fbset cheats by taking
times from the /etc/fb.mods file. I'm working on patch 
that was sent to me to deal with this.

Same problem again. It is a monitor timings issue. 
We are working on this.
