I'm writing a line discipline for a serial port multiplexing hardware
which turns one "upstream" serial port into 0-8 slower "downstream"
serial ports, according to the number of modules installed on the
multiplexer.

The attaching program transfers no data on the upstream port, all
data will be to/from the ldisc itself, or to/from the downstream
ports.

To know which modules are installed, and their configuration, the
ldisc needs to perform a handshake using the same packet format as
downstream port data transfers.

It would be nice to do this handshake in ldisc_open() so that the
attach can fail if the hardware is not responding or just not
connected.

Since the packet format is the same it would be easy to reuse the
normal ldisc receive path for the handshake, however the ldisc would
not see the response until after ldisc_open() has succeeded.
Catch-22!

I'm hoping to use ldattach for attaching the ldisc because it's nice
to have a standard utility, because it's nice to not duplicate the
packet formatting/parsing code, and because the ldisc has to know
which modules are installed in the hardware anyway, to create the
correct downstream ports.

Can you suggest a solution to this problem? Ideally one that can be
contained in the ldisc.


Thanks

Indeed.

Similar problem with the GSM mux I've been working on. I've gone for
making the ldisc attach always work and then kicking things off via an
ioctl which sets the desired mode/parameters/encoding.

I'll do the same. Did you add a new ioctl for this, or use an
existing one?


Thanks!

I added a private one - given I needed to pass the adaption layer code,
gsm mux level and whether we were initiator or not it didn't really fit
anything generic in the tty layer.

I was trying to reuse an existing ioctl, partly because I'm not sure
how to add a one and partly because fewer are better, but
TIOCSERCONFIG which seemed fitting does not appear to be passed on to
my ldisc. :\

Should I make a new one (what does private mean here btw?) and how do
I do it exactly? Is patching Documentation/ioctl/ioctl-number.txt and
asm/ioctls.h all? The "addressing" in ioctl-number seems a little
chaotic, do I just pick anything that is available?

I added an ioctl into a header of my own. It works fine, but..

Documentation/ioctl/ioctl-number.txt seems out of date. I picked
a number that was used (by linux/toshiba.h) but not listed. Do I have
to grep it out?

Can you at least list what files/drivers need to be added to
Documentation/ioctl/ioctl-number.txt, please?

Linus' include/linux/toshiba.h has a single ioctl:

#define TOSH_SMM _IOWR('t', 0x90, int)  /* broken: meant 24 bytes */

Maybe I picked the only unlisted number? :)
