Hi,
I am changing code in fs/binfmt_elf.c and I want to be able to add
this to the kernel and debug it without having to recompile the whole
kernel every time. There must be a way to do this.
How do I change the makefile so I can just compile the code and link it
in?
TIA,
Dan.

Can the user process let another process sleep & wakeup
like the kernel process wait queue?

Linux doesn't have drivers for individual printers. It has drivers for
the devices you use to connect printers to the computer, such as the
parallel, serial and/or USB ports. With those, anything on the computer
can talk to the printer just fine. What you are probably looking for is
the Ghostscript driver for that printer that will convert standard
Postscript level 1/2 into Canon's particular printer control language.
The 5100 isn't listed specifically, but Ghostscript does support the
BJC-600, BJC-4xxx, BJC-70, Stylewriter 2x00, and BJC-800 printers so
if the 5100 is listed in it's manual as being compatible with any of
those it should work. If not, visit http://www.cs.wisc.edu/~ghost/ and
check the latest version and see if support has been added via either
a standard driver or an additional driver you can obtain seperately
from Ghostscript.

The kernel makefile should already do a minimal recompile of only binfmt_elf.c.
Just issue a make command at the top level. Of course, it still has to recurse
into other directories and check the dependencies, which still takes a little
time. However it is not recompiling the whole kernel.

If you are only interested in x86 architecture, you can mmap /dev/mem,
the way svgalib or XFree86 do. In other architectures, the mapping of
bus address to cpu address might not be trivial, so you might need other
methods, but again, look at XFree86 (which runs on alpha and PPC) code.

I would like to know whether currently their is application software that
can make use of the PC camera (either uing USB or serial port) in Linux
system.
It is like conduct a video conference using the PC camera and both PC is
running he Linux OS.
Any idea or info on this is highly appreciated

Only on par port and with the Creative webcam II, that is what I wrote.
And not so much conferencing, but just internet connection.
http://www.panteltje.demon.nl/mcam/
OK, there is a webcam 4 linux mailing list.
webcam4linux - http://www.on-line.de/~m.wientapper
Maybe you could ask there.
As for the big world:
I have MS netmeeting, which has the advantage that non Linux users can
participate.
Its free I think (got mine with an ISP package).
Now if I knew the protocol, that would open the possibility to write
something compatible.
Maybe MS will release it?
But why bother, I just reboot in win 98.
mmm, maybe we do need to write one after all :-)
maybe someone already did this?

I am currently trying to translate the V4L Linux API to the Java Media
Framework 2.0 API although I am progressing slowly (due to the lack of
complete understanding of the JMF) I hope I will complete it in the next
month. After that it should not be difficult to use the demo program of the
JMF to send/recv video through the net. After that I will start writing a
videoconference program.
This is also a call to anyone who wish to help. If so send me a mail to

It took them eighty years since World War I, but
the French finally figured out how to kill Germans.
===================================================================
New Concorde schedules from Air France:-
Depart Paris CDG 1700
Arrive Hotel Gonesse 1703
===================================================================
Q.) What would the captain of the plane be doing today if he hadn't
been killed?
A.) Scratching weakly at the inside of his body bag.
===================================================================
Wealthy German tourists love the Hotel Gonesse. They drop in all the
time.
===================================================================
Q.) How many wealthy German tourists can fit into a VW Bug?
A.) 100. Four in the seats, 96 in the ashtray.

I personally use "vic" ("The MBONE VIdeo Conferencing tool"); it
supports several video standards, and multiple connections...
Look for "video conferencing Linux" in altavista, you'll probably run
into it. Try to find a binary (I didn't manage to compile the source
code - a lot of C errors (after I solved a bunch of 'em I gave up...)
and even some missing files - maybe I had an incorrect package, dunno).
The binary is easier anyway.
