When "foo" device detected, then kernel call /etc/hotplug/input.agent
Troubles are non-existing file systems in bootime, /proc and so on.
So all Your devices detected in boot time and input.agent has read-only
root filesytem and nothing more. This is main reason to use input device
drivers modular. Instead modules exists input.rc scripts, which do same.

hm, timing issues ?
fbcon trying to setup consoles before
matroxfb initialization is finished ?

may be we should experimenent to find the needed timeout,
but this is probably dependant on the system

or may be /* if it isn't already so */
fbcon should wait for a signal from the framebuffers
that they have finished initialization

good question

normally hotplug can be used only with modules after it#S available,
but the various *.rc scripts simulate a hotpluging event for drivers
which are built in or already loaded before hotplug was available

theoreticaly it should work, unless some needed functions are 
ifdef'ed MODULE

well you can have a VGA console built in and load the fb stuff
manually or with script later
just built fb drivers & fbcon modular and don't load them too early

/* no fancy graphics at boot, but a workable VGA console */

use VGA console and load the framebuffers & fbcon before starting X

it would be really nice, but ....
i think it's not possible with G550, not sure about G400/450
but it should work with Matrox MMS series or with different cards

well may be,
it would be nice to have a CONFIG_MATROXFB_SEPARATE_DISPLAYS,
but i'm not sure it's doable, and i'm sure Petr is not working on it :(
i think that the graphic BIOS initialize them in that way and the fbdriver 
will have to work around these BIOS settings

how do you setup the fb mode?

Hard to say what it was, because the screen was partially garbage.
The last line was a complaint about the kernel trying

Yes.  I usually compile my kernels with everything built-in
because I see no virtue in modules.  (They may be fine for
distribution kernels, but mu kernel is compiled for my machine
specifically.  I simply want to avoid all module setup & management,)

I made an exception here, by configuring fbcon as a module.  The
framebuffer driver and everything else still was compiled-in.

The part about temporarily moving fbcon.ko where modprobe couldn't
find it was just a hack to make the machine boot.  The module
crashes the kernel if it is loaded "too early", but the module
cannot be automatically loaded by the kernel if the
kernel cannot find it because I moved the file away from
its usual directory.

So it seems the framebuffer driver alone works under ruby,
even when compiled in.  fbcon works too, _if_ it
isn't loaded too early.  Bringing it up after
logging in via xdm were ok.

I don't have one, but it isn't all that hard to imagine.
At its best it looks like a ordinary console screen with
an xterm overlayed somehow.  One keyboard types into the
xterm, the other into the console.  Of course the two tend
to stomp on each other quite a bit, the console scrolling
the x desktop away and X repainting a bit here and there
now and then.

I'll try your patches.  
I like the built-in approach, it is nice to be able to
boot with init=/bin/sh and still get a console.

The dream is to just boot and get login prompts on
both screens with no further setup than running the 
gettys from /etc/inittab, and perhaps some kernel boot parameters.

The big problems with setup scripts is that they run late in the
boot process, early oopses or other trouble may prevent them
from running, I still want to read the text and be able to use sysrq.

I may go for modules and scripts for now, but hope the monolithic
approach will work someday. :-)

I believe this is an issue with the mga accelerated driver.
I get similiar problems whenever games change resolution on
the accelerated head.  I have my window manager set up with a key
combination that runs matroxset.  It'd be nice not
having to do this, but it'll probably be a long time.
X simply do more than it should.

I don't see why this should be unsolvable.  All matroxset do is
to run some ioctl's.  Surely the same code could be called from
within the framebuffer driver at boot time?  

I believe this was done because single-monitor setups are
common, and the kernel probably can't easily know where that
monitor is attached.  (Well, it could use DDC...)

But people don't buy a G550 to run single-monitor, so
having the kernel separate the displays and force the user
to think about which connector to use is fine with me.

I believe the garbage is stuff that vgacon left in graphichs memory before
handing the console over to the framebuffer.  At least this was the 
explanation when I complained about similiar garbage on a radeon
with framebuffer.  compiling _without_ vgacon indeed made all
the garbage go away, but the option to turn off vgacon recently
disappeared from menuconfig. :-(

Probably the logo code reserving some of the screen.  Odd that
it'd reserve the bottom part though.

just configure hotplug, install input.agent & input.rc

if it is the same issue /* and i think it is */
it was font.width == 0 + a function using  xxxx / fonth.width

PS.
i haven't tried yet built in matroxfb/ fbcon

i use this script to start multiple fbcon's

#!/bin/bash
modprobe matroxfb_base
modprobe matroxfb_crtc2
modprobe fbcon
# split the heads , we don't want head1 shown on head2
matroxfb_swapped

# adjust input devices,  we don't have /proc/bus/console/01

Aivils,
should ruby-260t9-20031115 really work OK without this patches ?

PS.5
the remaining issues 
/* most likely hardware limitations involved 
 * and XFree "bugs" too
 */

1.)  X->VT->X on head1 (vt7)
X head1 is displayed on both heads, VT switch on head2 fixes it

2.) the mentioned XFree hack should be integrated smarter,
currently you need additional binary for each additional fbcon

3.) probably unsolvable/ hardware
the need to run swapped from matroxset tarball to
separate the displays

4.) related to 3
after swapped, both heads are blank until a VT switch, 

and on head1 there is a lot of garbage until login + logout
actually the garbage is on all vc's except the first one (head 1)
but on all vc's usable is only 4/6 of the hight of the screen
the top 1/6 is ocupied by the logo, the bottom 1/6 by nothing
on vc1 and by garbage on vc2-vc6. 
Everything becomes normal after a login + logout , but until logout
only graphics(e.g. ncurses menuconfig)  paint to the entire screen,
a ls, ps, whatever will use only the middle 4/6 of the screen hight 

there is no such problem with head2 
/* which misses a blinking cursor, cursor is always on :-)  */

I updated from CVS 30.nov, and copied the source into 2.6.0-test11
This compiled fine, in several configurations.

Booting with framebuffer console compiled-in still oopses,
this time the oops was unreadable except for the last line
about killing init.

So I tried a modular fbcon, with a kernel configured to load
modules automatically when needed.  This booted in the same way,
loaded the fbcon module automatically and crashed just as the compiled-in
variant.  The readable part of the crash message said something
about mdrun exiting with a wrong preempt count.

So I moved fbcon.ko where modprobe couldn't find it, and
booted again.  The machine came up fine, obviously without a
console.  I moved the module back to its proper place,
and loaded it.  I immediately got two penguins (it's a dual processor
machine) on the screen running accelerated X.  This screen
has the keyboard connected to the ordinary ps2 keyboard plug
(recognized by the bios too).  Ruby places this at vt17. 
Pressing ctrl+alt+F1 here did nothing, no console switch.

The other keyboard is connected to the ps2 mouse plug,
and seen by X on vt7. Pressing ctrl+alt+F1 switched to a
console.  X blanked itself. Unfortunately the console appeared at the other
screen - so I had matrox console and X running there simultaneously.
Psycho circus again. :-(  The second screen just sat there.

I believe this might work better if I ran the vt7 xfree on 
the first display, but I have a good reason for not doing so:
It is sometimes necessary to access the bios setup, or boot non-ruby
versions of linux. In those cases the keyboard connected to the
ordinary keyboard plug is the only keyboard, and X happens
on the first screen. (/dev/fb0).  Moving keyboards or screens around the
room isn't very interesting, so this is the layout I want.

Life would be so much easier if ruby considered the ordinary
pc keyboard as the first one, and one connected to the "mouse" port
as the second one.  Or if the vt/keyboarddevice/console connections
could be specified using kernel parameters. any hope of swapping the
keyboards so the console/screen/keyboard/vt combination that works
for plain linux simply becomes the "first" set of connected devices 
using ruby?


Is there anything I could do to help find out why fbcon oopses
when it is available "too early"?  Perhaps it uses resources
not yet initialized?  Or races somehow?  
It seems to work when loaded after the normal boot, except that
it don't match my screen/keyboard mapping.

To this day probeonly trick works for all. You might try Nvidia suggested

Of course You can wait for official 2.6.0 support.

My advice is to take a look at /etc/securetty which
limits where root can log in.  I lost root logins upon
switching to and from devfs due to changing names of
the tty devices.  Make sure the "extra" consoles
are listed.

which developer count? 
ruby developers or xfree developers? 
there are already more users then ruby developers :-)

OK

and one more question 
can you login as root on secondary head ?
i can't :(
i can login as two different users on the second head,
but trying to login as root always returns "login failed"
any ideas?

USB mouse replug

[Aivils S. <Aiv...@un...>]

Hi All!

     What happen on USB device replug or restore after failure.
1) on unplug kernel remove device file (/dev/input/mouse0)
2) all open file descriptors become invalid, xf86 mouse device
  file descriptor included here.
3) on plug kernel creates device file again, but no more
  file descriptors point to this file.

Also, we should reopen device file in userspace program.
xf86 do not read bytes from device file periodic, but wait for
signals, which notify about changes. When kernel close device
file, then file descriptor is invalid and do not recive signals
from kernel, even kernel creates new device file, xf86 mouse is
dead.
I know how to reopen mouse device file. To recive signals i
use switch to text mode console and back to xf86. After xf86
patching i can unplug USB mouse , plug again, perform
Ctrl-Alt-F1,Ctrl-F7 and my xf86 works as nothing happens.
Of course as xf86 mouse device i use /dev/symlink_to_real_mouse,
created by input.agent. input.agent is necessary, because kernel
may instead /dev/input/mouse0 create /dev/input/mouse1.

Unfortunately 2nd xf86 user cannot switch to text mode console
and function pFoo->read_input() must be called forced , see file
xf86Events.c functions xf86Wakeup() xf86SigioReadInput().
Forced mode not implemented in my patch :( May be any other may help me
complete this stuff?

/proc is for lazy endusers. For userspace programms
more helpful is ioctl. James Simmons already suggest add
necessary ioctl-s for TTY. Now is time to play the game.

then You might buging everyone :o)

That is my bug. I cannot decide where i should add cursor
timer in fb_info or vt_struct. Current fbcon has single cursor
timer used by first head.

that does the trick :-)
now we(most likely you as the brain)  probably should find a smarter
solution
smth like :

sugestions
(order IMO easy to implemet->hard to implement & nice)

1.)
startx --- ./usr/X11R6/bin/X... -vt_shift 0 ( or omit) vt7
startx --- ./usr/X11R6/bin/X... -vt_shift 16 vt17
startx --- ./usr/X11R6/bin/X... -vt_shift 32 vt33

2.)
Option "SingleCard" "true"
Option "VtShift"       "0"  /* or omit */
.....
Option "SingleCard" "true"
Option "VtShift"       "16"
.....
Option "SingleCard" "true"
Option "VtShift"       "32"
.....

3.)
may be add /proc/bus/console/xx/vc_first
and teach XFree to use it

while on adding stuff :-)
don't you think it would be usefull to expose vc_first,vc_last or vc_range 
in proc ?

4.)
start buging the XFree developers ?
may be too early, when the F... will Linus leave 2.6 to Andrew
and open 2.7 , and when ruby will be merged ?

both heads with driver "fbdev" is the same ->
X(head 1)  switch to VC & back -> Problem
-->> X(head 1) displayed on both heads
++>> VT switch on head 2 fixes it 

X(head 2)  switch to VC & back -> everything OK
++>> X(head 1) displayed on head 1  
++>> X(head 2) displayed on head 2
 
order of starting X is not important
---------------------------------------------

there is one more ?issue? with the second head
the cursor never blinks, it stays all the time turned on
a bit strange but everything else is OK

Second head uses /dev/vc/17 to /dev/vc/32 , but xf86 will
switch Ctrl-Alt-F1 == /dev/vc/1 to neighbour console.

so i'll have to start over with the compilation :-)
could you send me/upload the new code ( i still don't trust sf's cvs)

<me sucks EAGAIN>
the old kernel , the one i used the last time for testing
does work with multiple framebuffer consoles :-)
i probably missed smth the previous time
:-) yes it works with 2users on the 2 heads :-)

but when i start x

1.) 
on the second head i can not switch to console
in the X log
"Failed to switch consoles (No such device or address)"

2.)
if i switch to console on the first head and then back to X,
i get the X(head 1) running on both heads
X(head2) continues to work, but as console swicthing doesn't work 
on X (head 2) i can not activate it,or switch to VC 
(needs more testing, tmp workaround kill X(head2) and restart it,
or do not switch to VC on 1st head)

3.)
 gdm locks the PC 
(may be needs some tweaking, testing
 starting X from fb console works in the already described way)

</me sucks>

best,

I mean linuxconsole.sf.net.
Latest CVS do not need vt3.diff and rc1.patch.
Overlapped code removed and fbcon should pop up properly.

ooooooops

sory

compilng the kernel now
i use the tarball you sent me + vt3.diff + rc1.patch

i haven't seen any changes on the cvs commit ml or do you mean latest bk
tree ?

svetljo

PS 
last time  -- without rc1 diff
everything seemd OK with one small problem that after running matroxset
(the only way to get independant heads) the second head just stays blank

may be
<me sucks>
how should i change the settings to valid ones with matroxset/fbset ?
</me sucks>

>Do you  have correctly setup CRTC <-> output mappings by 'matroxset'?

yes,
it works with X using fbdriver(2 independant heads), after loading the
modules
swapped from the matroxset tarball is runned, in the case with multiple
fb consoles  it blanks both heads - the first can be activated/ unblanked 
by console switch (ctrl-alt-Fx), the second remains blank :( 
(
multiple fb consoles were tested without starting X,
multiple X was used with single fbconsole & 1 dumb console
)

<me sucks<
why haven't i tried to use X to configure properly crtc2
</me sucks>

Only hardware owner may test it properly.
You should find "foobar" hardware owner and request
patched kernel tests. Also You should find some (5-10) arch
depended lines and patch they by yourself.

Server count is not limited.
Primary is free PCI slots.
Current lots of USB devices may will not run properly,
X lose mouse.

Can Backstreet Ruby run on 64-bit hardware?

[dave g. <giv...@ya...>]

Thanks for your help with getting a backstreet ruby
kernel to work for me.

I'm looking at getting a new more powerful computer
system and I'm wondering if anyone has tried
backstreet ruby on these systems or could forsee any
difficulties and/or impossibilities:

Dual Athlon64 based system
Dual Opteron based system
Dual Macintosh G5 system (running Linux)

Also, with a more powerful computer, I could host more
users, but I think backstreet ruby allows for a
maximum of 3 x servers simultaneously. Would it be
difficult to modify the kernel to get around this
limitation (say increasing the limit to 5 or 6?)

:)
