Hello,
I've developed a device driver for linux. Now I want to provide under
the GPL.
Therefore I search for places / ftp-Servers where I can put it, so that
everyone can download it.
Can anyone tell me where to put the driver and how to make it known?
Thanks,
Sven

According to Linux Device drivers (Alessandro Rubini, O'Reilly) are
memcpy_tofs and memcpy_fromfs removed in 2.1 kernels. It said that they
likely stay away in de 2.2 kernel.
In the book there is a file called sysdep-2.1.h which now use:
copy_from_user <> memcpy_tofs
copy_to_user <> memcpy_fromfs
Look for the example file belonging to the book. It is in there

The weird thing is that the sound card works fine with rvplayer for
example! So the sound modules themselves seem to work. That is why I cross
posted to comp.os.linux.development.system, because I think it is likely to
be a buglet rather than misconfiguration (although it would be easier if it
were the latter).

/usr/include/asm/segment.h in kernel 2.2.5 does not have memcpy_tofs(),
unlike the same file in kernel 2.0.36.

Hi everybody,
I'm looking for information about the minimum size a Linux system
could have to run on an embedded device. Let's talk about a PC
compatible machine, which is more realistic. Can somebody tell me how
much ROM and RAM spaces I need to run Linux with some features like
the network and the memory management of course.
Thanks.

You also need to update many utilities, module tools, networking... at
some point it becomes desirable to simply save the good stuff and
reload, when it's far less work than evolving. I've done a few systems
each way, a clean install from time to time is a good idea anyway.

2.0 was still "the latest" only a couple months back...
But there was a libaio for 2.0 (using threads) at
ftp://ftp.atd.ucar.edu/pub/thor/libaio-0.1.tgz from Richard Neitzel

Whoops!
As usual I figured out the problem shortly after posting it.
The "register_symtab( NULL ):" is the way to go.
It works better if you don't put it right after "#ifndef MODULE" and
then put -DMODULE as a compile option.
As Homer would say, "Dolt!". Sometimes I really wonder about myself.
Peace,

Yes, find out which version of gcc or egcc you are using, then ask in a
more appropriate newsgroup/mailing-list.
I'm sorry not to be more helpful, but c++ really has *so* little to do
with the development of the system parts of Linux that it's frightening.

If you use gcc, use something like:
./configure --target=i386-pc-linux
./configure --target=i386-pc-cygwin32
./configure --target=i386-pc-go32
(you may have to experiment to get the right target names for your
application)
and then compile gcc. The harder part is getting all of the libraries
and include files for the target in the right places for the cross
compiler to find them (use "gcc -v hello.c" to figure it out). Note
that libgcc.a compiled on the target (usually through a gcc native
install) is needed.

This is a followup for my request for help.
I'd like to thank H. J. Lu for supplying what the patches and knfsd and
the direction to get this working.
Hope this helps.
Problem : With a RH5.2 install and running the linux as a fileserver
to Solaris clients, NFS would fail when more than one client
connected. Failure included files becoming corrupted and nfsd
die'ing (sp?).
Note, I also had problems with the DEC OSF1 connecting to the
exported linux filesystem.
Solution :
Get the linux kernel 2.2.5. See www.kernel.org/pub.
A. Install RH 5.2.
B. Added the following rpm/patches :
XFree86-3_3_3-1_i386.rpm
Xconfigurator-3_89-1_i386.rpm
XFree86-SVGA-3.3.3.1-1.i386.rpm* libc-5.3.12-28.i386.rpm*
XFree86-SVGA-3_3_3_1-1_i386.rpm svgalib-1.3.0-3.i386.rpm*
XFree86-XF86Setup-3_3_3_1-1_i386.rpm sysklogd-1.3-26.i386.rpm*
XFree86-xfs-3_3_3_1-1_i386.rpm zgv-3.0-6.i386.rpm*
These patches are not required. Just the steps taken via my
install
method.
C. Obtain from ftp://ftp.varesearch.com/pub/support/hjl/knfsd/
knfsd-1.2.2a.tar.gz # this contains the patches for 2.2.
and the following rpm's from ../linux-2.2/RPMS/i386/
initscripts-3.78.1-3.i386.rpm
nfs-server-2.2beta37-1.1.i386.rpm
nfs-server-clients-2.2beta37-1.1.i386.rpm
knfsd-1.2-2.i386.rpm
D. cd /usr/src; rm linux # remove linux link
E. Add patches to 2.2.5 kernel. Patches are part of the
knfsd-1.2.2a.tar.gz kit.
Build new kernel.
- make clean
- make xconfig
- select Code maturity level options. Select y.
- select Network File Systems. Select NFS server support.
- save and exit
- make dep
- make clean
- make zImage
- make install
- make modules
- make modules_install
- Edit /etc/lilo.conf ; modify to /boot/vmlinuz. lilo.
- reboot
F. Install the rpms :
- rpm -U initscripts-3.78.1-3.i386.rpm
# note, /etc/rc.d/init.d/network modified.
- rpm -U nfs-server-2.2beta37-1.1.i386.rpm
- rpm -U nfs-server-clients-2.2beta37-1.1.i386.rpm
- rpm -i knfsd-1.2-2.i386.rpm
G. Setup the startup scripts.
Copy the rpc.nfsd and rpc.nfsfs from the knfsd-1.2.2a/etc area.
[/etc/rc.d/init.d]# mv nfs nfs.orig
[/etc/rc.d/init.d]# mv nfsfs nfsfs.orig
[/etc/rc.d/init.d]# mv knfsd-1.2.2a/etc/rc.nfsd nfs
[/etc/rc.d/init.d]# mv knfsd-1.2.2a/etc/rc.nfsfs nfsfs
[/etc/rc.d/init.d]# chmod 755 nfs*
Don't forget to export the filesystem, via the /etc/exports file:
