ruby CVS updates

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

Hi all!
     ruby-2.6 moving. Now /dev/tty0 must work correct. /dev/tty0 now
works similar Linus tree kernel. /dev/tty0 is current for each VT. We have
multiple current ttys. Process get current tty depend from VT , where
process
was spawned. Now VCs of VT are shifted. VGA has vc:1-16. DUMMY has only one
VC per VT.
     Keyboard leds switch incorrect when user switch from one VC to another
- this one fixed now.
     Uploaded initial version of framebuffer console. Thanks James Linus
tree kernel already has ruby friendly fbcon code. Porting to ruby is
relative
easy. fbcon right now can serve only one framebuffer device driver
correctly.
Real multiuser, where each fb device has a keyboard, will be added in
future.
If You will test this code, then please select one fb device driver only.
In
my case, fbcon works with Voodoo3. Of course fbcon contain some bugs. You
have
simple arithmetic - if I not clean vgacon during one year, then fbcon is
hopeless :-( Oops You can do via ioctl on /dev/fbX , because they are
untested
and dangerous. fbcon take over VGA console. In real-multiuser case each new
fb device should not take over VGA - we must have kernel command line
options
for each framebuffer device driver. All fb drivers use one fbcon.

TODO: sync to recent kernel.

the notes were ment as addition to the deskription

you wont find it cause it's named differently :)
you shouldn't edit your .config with an editor
you should use "make menuconfig" or "make xconfig"

i thought there were snapshots at Aivils site 
but it seems they are missing
you can check them here
http://varna.demon.co.uk/~svetlio/aivils2/quick-eng.html 

Aivils,
i think you have the snapshots on your site,
but the links seems to be missing.
me missed smth? or the links got lost somehow? :)

look for links "mc" & "xc" arround the descriptions

i'm using the prefered format by tldp.org (docbook xml)
which allows from a single xml file to get pdf, html (single, multi-page). txt
and some other formats too.

any help is wellcome :-)
if you have some time
check my web site http://varna.demon.co.uk/~svetlio/ -> linux
in the how-to section are listed some really "nice to have" things 
i have a mixed TODO :-)
and you can find on several places in the HOWTO
things that needs feedback, or are marked as experimental
(reason tested only by me, or the like)

from the things i wish to add( not yet listed)
- bruby + ltsp/ k12ltsp
- using indepenedent USB/ firewire devices
- is it possible to use a multi-chanel sound card instead of 2 dual-chanel cards
for 2 independent users ( i had in mind to write to alsa project, but ...)
- really test Matrox MMS series ( toooooo expensive)
- had some more thoughts but can not remmember right now :(
- write to the author of gdm, and ask him whether gdm2 will support
  different themes for different displays

so, if you have time, there are lot of things to do :-)

best,

Howto Section 3.2

[hugo v. <hug...@ca...>]

Hi Svetjlo!

I don't get Section 3.2, the beginning, but may
be my "getting capability" is low, 

1. what does it mean when it says:

You have to follow this order

2. In the subsequent list I cannot find in my
.config "virtual terminal support"

3. In the next point: You have to use built in
input support: I cannot find either "input core
support"

BTW if you want help with the maintenance of the
Howto I will be glad to help. I now use
Hyperlatex: that gives you html support through a
tex file and so you get the pdf and the html both
at the same time by just maintaining the .tex file.

Hi Aivils and Svetljo!

Thanks for answering so quickly!

Indeed the problem with ***INITIALIZATION
FAILED*** is solved doing the -probeonly
as specified in section 8.1 of the HowTo. Sorry,
I should have followed up.

However, after adding BusID       "PCI:1:0:0" and
BusID       "PCI:0:11:0" to the device
sections of XF86Config-4.ruby and XF86Config.new
(per my post of yesterday)
I still have 2 problems:

1. I can start the :1 server from :0 with:
     startx -- /usr/X11R6/bin/X1 :1 -xf86config
XF86Config.new vt9
   but after that :0 has no keyboard and sits
there until I Ctrl+Alt+Backsp :1

   I can start the :0 server from :0 with:
     startx -- /usr/X11R6/bin/X0 :0 -xf86config
XF86Config-4.ruby vt7
   and I still have the :0 keyboard, of course
nothing on :1.
   
2. If I add to my @Xserver for xdm:

:0 local usr/bin/nice -n -10 /usr/X11R6/bin/X0 :0
-xf86config /etc/X11/XF86Config-4.ruby
-deferglyphs 16 vt7
:1 local usr/bin/nice -n -10 /usr/X11R6/bin/X1 :1
-xf86config /etc/X11/XF86Config.new -deferglyphs
16 vt9

   and start xdm, :0 screen goes blank and the
system freezes and I have to hit the red button.
   
Any ideas?

Thanks a lot!

Hugo.

You be sure to add -prefbusid command line option. Without this option
xf86 runs identical unpatched xf86. Stock xf86 search and freezy any video
adapter on system.

:0 local usr/bin/nice -n -10 /usr/X11R6/bin/X0 :0

-xf86config /etc/X11/XF86Config.new -deferglyphs

Don't forget add Nvidia stuff "X -probeonly" in system init scripts, before
xdm starting.

standard Xfree behaviour :)
have you added "SingleCard" "true"
or "PrefBusID" "x:xx:x" to your XF config file ?
you might also want to check which is the version of the patch
used. I think Andreas have not updated yet to patch version 3 & his XFree
binaries still use version 1, which means that to get rid of this problem
(the standard XFree behaviour) you should use cmd argument -prefbusid x:xx:x
when starting X

Howto section 4.3

[hugo v. <hug...@ca...>]

Hi!

In section 4.3 of the Howto it says to create the
links to "XFree[modified]", however, on
installing the modified X Debian package, I have
in /usr/X11R6/bin executables "X" and "XFree86".
I made the X0 and X1 links to X, because doing it
to XFree86 produces weird results when you startx.

X and XFree86 both have man pages but the X man
does not seem to refer to /usr/X11R6/bin/X.

The XFree86 man does seem to refer to XFree86.

Both X and XFree86 have mtimes of april 22 2003.

I check out it. This is big, deep trouble.

linus-tree kernel uses two TTY drivers. 1st for /dev/tty0
and 2nd /dev/tty1-63. So VC console count for VT begins from 1.

Linux-ruby uses one TTY diver for /dev/tty0-63. This is practical solution,
because it is pretty stable. Stability as well not guaranted correct work
of
code. Under linux-ruby /dev/tty0 is just another TTY from VT0 pool. Since
James remove tty0 handling from tty_open(), I understand James has no plans
for tty0. I has no plans to, because don't understand how works TTY driver.

In curreent ruby state tty0 works almost correct for VT0.
If process spawned from VT1 tty pool, then process can get wrong data
about VT1, if that use /dev/tty0 (VT_GETSTATE,VT_OPENQRY).

Why trouble is so deep?
IMHO we cannot serve multiple opens of /dev/tty0 correct, if processes,
which uses /dev/tty0, are spawned from different VT.

Seems making /dev/tty0 as current for all VTs is not so easy.

Alt-Fx is shifted because under linux-ruby console count begins from 0.
This one is easy fixable for VT0.

This is standard trouble for Nvidia drivers.
You must initialize Nvidia kernel module:
/usr/X11R6/bin/X1 -probeonly -xf86config XF86Config.new
after this You can type commands as You wrote.
I cannot explain this feature. If You have 3
Nvidia adapters, then You must find right
adapter which initialize Nvidia kernel module
properly. Right adapter to start depend from Nvidia driver
version.
Under Mandrake i have:
http://startx.times.lv/mdk/dm

-prefbusid option hide unwanted adapters from xf86.
xf86 see only one adapter. This don't like Nvidia
kernel module, which needs for all adapters. We load
nvidia kernel module with all adapters info, when
xf86 -probeonly is called.

1st started xf86 load nvidia kernel module. For test
You can do "rmmod nvidia".

Right. Keyboard device set vtXX commandline option.
Of course video device may diff.
I recommend set up BusID for each video adapter.

Failed to init NVidia module

[hugo v. <hug...@ca...>]

Hi Ruby Cognoscendi!

After a long planning period, got:

2 IBM Model M PS/2 keyboards with ps/2 mini dins
(where the mini-dins for kbd + mouse go)
2 A4tech optical mice with USB (in the 2 usb ports)
1 video card AGP NVidia RIVA TNT2 Model 64/Model
64 Pro (in the AGP slot)
1 video card PCI NVidia GeForce4 MX 440 (in a PCI
slot)
2 Samsung 17" 750s monitors, one in AGP video
card other in PCI video card

On Debian got the latest XFree .deb package from
http://www.schuldei.org/debian/bruby
Installed 2.4.21 vanilla kernel and applied the
patch bruby-2.4.21-20030615.diff

Also installed the NVidia kernel module with
their .run ( no parameters used)

PROBLEM:

I can start xdm or startx on the AGP monitor
(which comes up first because I changed the
BIOS init_display_first to AGP, default=pci) by:

 "startx -- /usr/X11R6/bin/X0 :0 -xf86config
XF86Config-4.ruby -prefbusid 1:0:0 vt7"
 
and X starts and I have mouse and kbd.

But I cannot:

 "startx -- /usr/X11R6/bin/X1 :1 -xf86config
XF86Config.new -prefbusid 0:11:0 vt9" 
 
under X or anywhere without getting: "Failed to
init NVidia module"

Which I don't understand: if he can find it in
XF86Config-4.ruby why not in XF86Config.new
since the only diff between the 2 is the mouse
device?

THE DOCUMENTATION:
1. dmesg here: http://home.planet.nl/~woerk095/dmesg
2. lsmod here: http://home.planet.nl/~woerk095/lsmod
3. cat /proc/bus/console/*/* here:
http://home.planet.nl/~woerk095/console 
4. cat /proc/input/devices   here:
http://home.planet.nl/~woerk095/input   
5. cat /proc/usb/devices   here:
http://home.planet.nl/~woerk095/usb   
6. config for :0 here:
http://home.planet.nl/~woerk095/XF86Config-4.ruby
7. config for :1 here:
http://home.planet.nl/~woerk095/XF86Config.new
8. log for :0 here:
http://home.planet.nl/~woerk095/XFree86.0.log
9. log for :1 here:
http://home.planet.nl/~woerk095/XFree86.1.log

I surely missed something in the documentation
(latest HowTo). But...
I would be very willing to tackle updating a Ruby
FAQ, so that these kind of questions can be
avoided. As it is, I found it not necessary to
hide the NVidia lib because both cards can
use the closed source driver. (I have used the
driver on both cards singly, but never
together...)

Thanks!

Hugo.

Hi!

I was unable to print using the xprt server from

enough only mozilla 1.0 told me there was a

apt-get install xprt-xprintorg under sid fixes
the problem because it installs a newer xprt server.

my question was about 2.6 :-)
it was on your to do list, but you also wrote "i use it"
so if you use it, why is it on the todo list ?

hm i never got ruby-2.4 runing, but bruby worked always :)
 

i had questions from 6-7 users, and at least 6 :) got it up and running
2 users with 3 displays(on 2-3 PC's),
the rest 2 displays but this is still TOOOO FEW :(

if we talk for graphic cards in serial production( ie from the shop)
it's not nessecary to be fbdev 
(and with fbdev it will be probably harder i think)

there quite a lot mainboards with 6 PCI + 1AGP slots
if you get several Matrox MMS cards, 
each with 4 heads(and chips with different BusID)
then you even can use the mga driver (acceleration, XV, ...)
but currently DRI actually doesn't work with more then one card :(

and i never could test even with single card cause they are pretty exspensive

are there any other cards with similar configuration ?

dummy is stable solution, because gonna smart :)
Users (me to) like xf86. Users (me to) like GLX accelerated xf86.
xf86 mostly initialize secondary video adapters pefect.
Posible PPC users (none known) may start ruby right now with dummy console
only.

fb_con is abstract layer now. Have You spare time to rewrite it
for single console under ruby ?
May VGA and any fb runs simultaneous?
Init fb VIDEOBIOS-less secondary adapters corectly?
libint10 is very higly polished under xf86, but i dont know
how about fbdev.

dummy console nobody take over. I split dummy init in two parts.
1st boot time with MAX_NR_USER_CONSOLES and additional dummy for
xf86 servers.

Ok. Very skilled users can test linux-ruby without recompiling xf86
of their distro. At least 2 pci video adapters runs flawless with

variable VCs per VT is needed for additional dummy console. Some furious
users of fbdev uses 24 VCs.

How about fbcon which uses only one VT as VGA ?

Under 2.4 speaker take aditional VT.

Seems VCs should be in 2 between 16. 16 allow only 4 VT which is to few
for USB two interface keyboars, which takes two VT per each. I mean 16 for
real console with hardware output and 2 for dummy. VCs per VT count must
set up  in console init routine and this count remain fixed all console
lifetime. I do not mean runtime variable count of VCs per VT. This is done.

vt_map_display() return NULL for redundant consoles - so reject it. This
one limit count of REALTERMINAL.

we need special ioctl. VT_GETSTATE don't care how many VCs has a
REALTERMINAL.

IMHO we should change terminology. All linus tree kernel ioctl-s return
information about single REALTERMINAL, which has noname, because it is
a one. Under ruby You create vt_struct which contain information about
current REALTERMINAL. I use REALTERMINAL , because this is a union of
real-output-device and real-input-device, so we lost virtuality. Of
course this is not real teletypewriter just emulator. You by yourself
design all ioctl-s against current REALTERMINAL. VT_GETSTATE return info
about bunch of VCs of current REALTERMINAL.
I write this because very hard understand about what is a talkshow.
I suggest rename vt_struct to rt_struct and use anyplace abbreviation
rt. This one allow more easy explaining how to linux-ruby works.
And eliminate misunderstanding VT,VC and unnamed REALTERMINAL.

>I assume you are
>doing this so you can more than one dummycon registered correct?

Yes. I will use multiple dummy consoles with small VCs count.
