To: Greg KH; +Cc: linux-kernel, Arnd Bergmann
This separates the core tty code from tty and other
character device drivers, in order to get a cleaner
structure.

menu "Character devices"

- bool "Virtual terminal" if EMBEDDED
- depends on !S390
- select INPUT
- default y
- ---help---
- If you say Y here, you will get support for terminal devices with
- display and keyboard devices. These are called "virtual" because you
- can run several virtual terminals (also called virtual consoles) on
- one physical terminal. This is rather useful, for example one
- virtual terminal can collect system messages and warnings, another
- one can be used for a text-mode user session, and a third could run
- an X session, all in parallel. Switching between virtual terminals
- is done with certain key combinations, usually Alt-<function key>.
-
- The setterm command ("man setterm") can be used to change the
- properties (such as colors or beeping) of a virtual terminal. The
- man page console_codes(4) ("man console_codes") contains the special
- character sequences that can be used to change those properties
- directly. The fonts used on virtual terminals can be changed with
- the setfont ("man setfont") command and the key bindings are defined
- with the loadkeys ("man loadkeys") command.
-
- You need at least one virtual terminal device in order to make use
- of your keyboard and monitor. Therefore, only people configuring an
- embedded system would want to say N here in order to save some
- memory; the only way to log into such a system is then via a serial
- or network connection.
-
- If unsure, say Y, or else you won't be able to do much with your new
- shiny Linux system :-)

-
-config VT_CONSOLE
- bool "Support for console on virtual terminal" if EMBEDDED
- depends on VT
- default y
- ---help---
- The system console is the device which receives all kernel messages
- and warnings and which allows logins in single user mode. If you
- answer Y here, a virtual terminal (the device used to interact with
- a physical terminal) can be used as system console. This is the most
- common mode of operations, so you should say Y here unless you want
- the kernel messages be output only to a serial port (in which case
- you should say Y to "Console on serial port", below).
-
- If you do say Y here, by default the currently visible virtual
- terminal (/dev/tty0) will be used as system console. You can change
- that with a kernel command line option such as "console=tty3" which
- would use the third virtual terminal as system console. (Try "man
- bootparam" or see the documentation of your boot loader (lilo or
- loadlin) about how to pass options to the kernel at boot time.)
-
- If unsure, say Y.
-

-
-config VT_HW_CONSOLE_BINDING
- bool "Support for binding and unbinding console drivers"
- depends on HW_CONSOLE
- default n
- ---help---
- The virtual terminal is the device that interacts with the physical
- terminal through console drivers. On these systems, at least one
- console driver is loaded. In other configurations, additional console
- drivers may be enabled, such as the framebuffer console. If more than
- 1 console driver is enabled, setting this to 'y' will allow you to
- select the console driver that will serve as the backend for the
- virtual terminals.
-
- See <file:Documentation/console/console.txt> for more
- information. For framebuffer console users, please refer to
- <file:Documentation/fb/fbcon.txt>.

+config VT
+ bool "Virtual terminal" if EMBEDDED
+ depends on !S390
+ select INPUT
+ default y
+ ---help---
+ If you say Y here, you will get support for terminal devices with
+ display and keyboard devices. These are called "virtual" because you
+ can run several virtual terminals (also called virtual consoles) on
+ one physical terminal. This is rather useful, for example one
+ virtual terminal can collect system messages and warnings, another
+ one can be used for a text-mode user session, and a third could run
+ an X session, all in parallel. Switching between virtual terminals
+ is done with certain key combinations, usually Alt-<function key>.
+
+ The setterm command ("man setterm") can be used to change the
+ properties (such as colors or beeping) of a virtual terminal. The
+ man page console_codes(4) ("man console_codes") contains the special
+ character sequences that can be used to change those properties
+ directly. The fonts used on virtual terminals can be changed with
+ the setfont ("man setfont") command and the key bindings are defined
+ with the loadkeys ("man loadkeys") command.
+
+ You need at least one virtual terminal device in order to make use
+ of your keyboard and monitor. Therefore, only people configuring an
+ embedded system would want to say N here in order to save some
+ memory; the only way to log into such a system is then via a serial
+ or network connection.
+
+ If unsure, say Y, or else you won't be able to do much with your new
+ shiny Linux system :-)
+

+ on virtual consoles.
+
+config VT_CONSOLE
+ bool "Support for console on virtual terminal" if EMBEDDED
+ depends on VT
+ default y
+ ---help---
+ The system console is the device which receives all kernel messages
+ and warnings and which allows logins in single user mode. If you
+ answer Y here, a virtual terminal (the device used to interact with
+ a physical terminal) can be used as system console. This is the most
+ common mode of operations, so you should say Y here unless you want
+ the kernel messages be output only to a serial port (in which case
+ you should say Y to "Console on serial port", below).
+
+ If you do say Y here, by default the currently visible virtual
+ terminal (/dev/tty0) will be used as system console. You can change
+ that with a kernel command line option such as "console=tty3" which
+ would use the third virtual terminal as system console. (Try "man
+ bootparam" or see the documentation of your boot loader (lilo or
+ loadlin) about how to pass options to the kernel at boot time.)
+
+ If unsure, say Y.
+

+ bool
+ depends on VT && !S390 && !UML
+ default y
+
+config VT_HW_CONSOLE_BINDING
+ bool "Support for binding and unbinding console drivers"
+ depends on HW_CONSOLE
+ default n
+ ---help---
+ The virtual terminal is the device that interacts with the physical
+ terminal through console drivers. On these systems, at least one
+ console driver is loaded. In other configurations, additional console
+ drivers may be enabled, such as the framebuffer console. If more than
+ 1 console driver is enabled, setting this to 'y' will allow you to
+ select the console driver that will serve as the backend for the
+ virtual terminals.
+
+ See <file:Documentation/console/console.txt> for more
+ information. For framebuffer console users, please refer to
+ <file:Documentation/fb/fbcon.txt>.

All hvc device drivers fall into the same category
of tty drivers, so it makes sense to keep them
in a single directory.

does it need to be in tty/hw/ ? seems like there's so little in tty/

Well, the idea here was to split the stuff that is commonly used
from the obsolete drivers.
BTW, the bfin_jtag_comm.c looks less obsolete than the rest of those
drivers, so I wasn't completely sure whether or not to move it into
the same place as the others.
My impression was that it should actually be converted into an hvc
driver as a cleanup and moved to drivers/tty/hvc. It can probably
get reduced to one third of its size if you do that.

Not sure it makes sense - hvc seems the wrong abstraction.

It seems to be very similar to hvc_tile.c in purpose, which is
the most trivial driver we have. Why would that not work?
Most of bfin_jtag_comm is about interfacing with the tty layer
and providing a kernel thread to do the polling, which is exactly
what hvc_console.c does.

i have no idea what "hvc" is, but my limited knowledge was that it was
for large powerpc servers, so i didnt bother looking at it too much.
i simply wanted a way to create a tty on top of the hardware channel.
if there is a framework that doesnt break this usage and lets me
simplify my driver, then either works for me.

HVC started out as the console for large powerpc, but has turned into
a generic framework for TTY drivers that are based on simple read/write
operations with or without interrupts.
Please take a look at drivers/char/hvc_tile.c, which was added recently
for a scenario quite similar to yours (debug port, not irq).

This makes the layout of Kconfig reflect the
new directory structure for the tty device
drivers.
Most significantly, the tty drivers now have
their own menu below the device drivers menu,
instead of being mixed with the other character
device drivers.
All serial drivers that are still registering
to the tty layer instead of to the serial or
hvc drivers are now in the 'nonstandard serial
port' category.

Linus actually suggested this should get done in some form a while ago

to be.

drivers/serial should also walk into tty I think ?
drivers/pcmcia/serial is a bit trickier but I guess should stay as with
drivers/usb/serial
There are several unbuildable ancient drivers. Perhaps if we are having
the great rename those should simply get deleted first, as there is no
way to test them in their current config ?

Do you consider vt to be core (I guess yes)? What about hvc (I guess no)?

Yes, good point.

I don't see drivers/pcmcia/serial. Are you thinking of the tty drivers
in drivers/char/pcmcia? I moved both of these to drivers/tty/hw
in my patch.

AFAICT, the only ones that are getting nontrivial updates once in

nozomi, serial167, stallion and synclink, while the users of
generic_serial.o seem to be the ones getting the least attention.

These 4 may go probably. I remember Alan suggested epca to be removed

though.)

Are they all candidates for a conversion to serial_core then?
Or are they not sufficiently 8250-like?

Please don't convert stuff to serial_core - it's got some horrible
problems with adapting to the new locking model, its buffering model
pre-dates kfifo and all in all serial_core needs a rewrite not more users.

Ok. I was under the illusion that drivers/serial contained the good
stuff while drivers/char/ had all the bad serial drivers that nobody
cared to convert. Do I understand you correctly that there is actually
not a single serial driver that can serve as a good example for other
drivers then?

I like the idea, and after you've worked out with Alan which ones should
be "deleted" and others moved around, I'll be glad to apply these types
of patches.
Oh, we shouldn't just delete the drivers, we can move them to
drivers/staging/ where they will then be removed after 2 kernel releases
if no one steps up to fix/maintain them. That's the "proper" way to
depreciate a driver.

Nah, it's no problem to this, git can handle renames just fine :)

Ok, I was already wondering if this would be the right way.
With the feedback I have so far, I think we have
drivers/char/tty_* -> tty/*
drivers/char/{vt stuff} -> tty/vt/
drivers/char/hvc_* -> drivers/tty/hvc/hvc_*
drivers/serial/* -> drivers/tty/serial/*
drivers/usb/serial -> drivers/usb/serial
cyclades,moxa,mxser -> drivers/tty/hw/
stallion,istallion,
epca,specialix,ip2,
riscom,isicom -> drivers/staging/tty/*
generic_serial,vme_scc,
ser_a2232,sx,rio -> drivers/staging/generic_serial/*
amiserial,nozomi,
serial167,synclink -> drivers/tty/hw (?)
bfin_jtag_comm -> drivers/tty/hvc/hvc_bfin_jtag (?)
rocket,ipwireless -> drivers/staging/tty/* (?)
I'll wait a few days for other suggestions and then prepare
a new patch series.

I wouldn't go for hw subdir. IMHO 'drivers' is enough.

Yeah, sorry I forgot about nozomi. It is used by some 3G cards or
anything currently. It was added only few years ago and people report
bugs against that too :), so is in use.

isicom has users and gets tested a bit, not sure about ip2/specialix.

Why /hw - its a tty driver so drivers/tty - the non hw stuff is now in
tty/
serial167 is dead/staging stuff, synclink* are used

Nothing to do with hvc

Rocket is used, ipwireless I think is also used

Are you sure about isicom:
https://bugzilla.kernel.org/show_bug.cgi?id=11067
? The last kernel he tried was 2.6.28 and there isicom sleeps forever in
isicom_open.

There certainly were people using it, which suggests maybe it needs
looking at not binning.

Perhaps it's better to remove your name

Geert, can you comment on the 68k serial drivers? Which
ones are to stay, which ones can get phased out?

I'll leave isicom then.
Specialix is marked in MAINTAINERS as supported by Roger, ip2
is maintained by Michael, maybe they have a preference for their
drivers.
Both drivers have a web page that is ~10 years old, which hints
that there is probably not much new hardware around.

Not yet ;-)
You didn't reply to my question why it couldn't be. I'll let Mike
judge this one when he has looked at the hvc infrastructure.
I wouldn't move it to that directory unless the code gets changed
first, but I wanted to write down where I think it should end up.

Hi,
The question is whether I want the drivers I wrote to stay or to
go away?
I was paid years ago to make Linux support the Specialix cards. It
started with one card from their line of "solutions", but the others
followed.
I personally don't use "serial" very much anymore. If I do, I end up
getting an USB-serial converter for $3 in China (includes shipping).
But my personal interest in the serial protocol is that I interface
with microcontrollers. The mess of the +/- 12V levels is a nuisance.
Other people might use "serial" devices because they are stuck with a
historical setup. If you have a factory with a well-designed computer
system, it is very well possible that some installations are still
running with a serial terminal on every desk. Some desks will have a
windows PC and a terminal application, but the serial interface to the
central "mainframe" will still be maintained.
Those central "mainframes" might be Linux PCs. The Linux PCs replaced
older hardware and software. Maybe they were running SCO or another
Unix variant, and through the years the application was ported to
Linux.
In those setups, I can imagine a 8-port or 32-port serial card to be
useful. It would be nice that people supporting that sort of setup
would be able to install Ubuntu 10.10 and have their hardware simply
work. Buying new multiport serial cards seems unneccesary unless they
are ISA. But specialix cards are available in PCI. So if you already
have PCI cards why force them to new hardware if they have hardware
that works?
Oh! One more thing. The sysops at shops that use these multiport
serial cards are not the types to monitor Linux-kernel and make waves
if support for their card is going to be dropped.
Now I've missed the first part of this discussion... Is there a change
imminent that requires rewriting of all the drivers?
(If rewriting serial drivers, PLEASE make it so that the
userspace-kernel interface just passes a baud rate integer, not the
one-of-16-possible baudrate-flags. The old stuff can be emulated in a
library. Secondly serial port drivers should NOT have to worry about
DCD changes and what to do with sleeping processes. The driver should
have an kernel function to call: "hey, one of the control lines
changed level. These are the new ones". And "These characters
arrived". And the driver has an entry point: "please send these
characters". )
Roger.

Mostly locking - it's not a trivial entry point thing. The gs layer for
example was full of races and needed rewriting so just got declared
broken.

Did that several years ago. I think you still need to use the ioctl
because several years is apparently a bit short for glibc to get with it
even though a glibc person thought up how to do the new interface 8)

Mostly done. See tty_port_*

The most important question is whether you think that there are people
somewhere in the world that are using the device drivers on machines
with recent kernels.
If you still get bug reports for the drivers, that would be a clear
indication to make them stay, while if you haven't heard from a user
during the last five years, it's probably obsolete enough that it
can be removed (after a few kernels of grace period in drivers/staging).

And it is always possible to revert a removal at a later time and fix up
a driver if someone does show up in a few years asking where the driver
went.

My story is very similar with the Computone Intelliport II boards. I
was paid (in hardware) by Computone to get their drivers integrated into
the mainline kernel and support them. That was a long long time ago.
The boards have not been manufactured in over a decade and the company
went of of business a long time ago. I'm still in touch with several of
the old developers that use to work there.

Every once in a while I'll hear from someone who picked up some old
boards on E-Bay or something inquiring about the drivers and how do they
set it up. I strongly discourage anyone from setting up a new project
with these boards. They were expensive at the time and replacements are
going to be impossible to find. I send every new inquiry over to look
at the USB serial converters (there are some really nice 8 port and 16
port units out there as well as the singles) that are cheaper and will
be possible to replace if and when they break.
I do hear, once in a very long while, from some of the legacy users of
those boards. They love'm. But they're mostly staying on the 2.4
kernel anyways and not upgrading. More often than not, it's some
problem getting them to work on some new motherboard after repairing or
upgrading a system. I wouldn't be surprised if some of these shops
haven't discovered that they can not get replacement boards and migrated
over to USB. It actually has been quite some time since I last heard
from anyone.
That driver supported 256 serial ports with a couple of different
interfaces resulting in 3 whole majors allocated to it. Even back then,
that seemed like such a waste for such an obscure board.
At this point in time, I would have no heartburn if that driver was
relegated to legacy status and those 3 majors freed up.

That was exactly why I got involved with Computone. I had customers on
SCO Unix plus my own setup and I wanted to get everyone off that OS.

Computone Intelliport II boards were also available in PCI. Now days,
you can pick up an 8 port USB to serial converter for under $30 that
will do just as well as one of those boards use to do.

They're also not likely to be running the latest and greatest on those

Ok, so it sounds both of you successfully managed to maintain the device
drivers way beyond the life time of the hardware, great work!
Let's send the drivers into their well-earned retirement in drivers/staging
where they can die from a natural cause. If someone still has a use for
them after all, we can always bring them back and he or she can become
the new maintainer ;-).

Dipping an interested oar in this water, but speaking purely from the user
viewpoint;
That is all well and good I suppose, but please ask yourselves if there are
suitable _modern_ replacements for this hardware, and are the drivers
available in linux?
If there are not suitable replacements, buy able at the likes of newegg et
all, then this attitude seems a bit premature.
I presume the same can be said of the rocketport drivers, I haven't seen
those boards for sale in yonks, but there are probably at least 1 of them
in every television station in the country (USA), doing wire service
capture.

As far as I understand, these are all fairly simple (by today's standards)
serial boards, so the assumption is that anyone running a machine with
a 2.6.35 kernel would get a $5 (more for mulitport) USB serial adapter.

Ok, good to know, this is the kind of information I was looking for.
I agree that as long as there are users, we shouldn't just kill the drivers.
For rocket.c, Alan already mentioned that there users left, so it's not
going away.
Note that there are also cases where we know that users exist, but for some
reason they are all stuck on 2.4 kernels or older anyway, so there is no
point in keeping the driver for new kernel releases. Also, we can always
add them back if the situation changes or we hear of users we didn't
know about.

right ... as long as it isnt hvc, it should be .../tty/hw/. when/if
it is converted to hvc, i'll also take care of moving it to the hvc/
subdir.
ive opened a tracker item for the issue, but no promise as to when
i'll look into it :p.

I don't know much about which drivers are still in active use. People
don't really
tell me ;-)
FWIW, if I use my Amiga's serial port, it's just for a serial console, in case
all else fails (last time I needed that was several years ago).
We have 3 "classes" of serial drivers:
- generic_serial-based:
o MVME147_SCC
o MVME162_SCC
o BVME6000_SCC
o A2232
All of these were marked BROKEN lately due to generic_serial,
while there's even a
new ATARI_SCC under "active" development...
- plain drivers/char:
o SERIAL167
o AMIGA_BUILTIN_SERIAL
- drivers/serial:
o SERIAL_PMACZILOG (Mac)
Sun 3/3x support might be (re)added to SERIAL_SUNZILOG

Funny... so "fortunately" we never found time to move the m68k serial drivers
to driver/serial/? Long live procrastination ;-)

Ok, so I'll keep the plan of moving generic_serial to staging.

Since these are the builtin ports for the Amiga and MVME16x
platforms, I suppose we should keep them around as long as the
platforms themselves are there and the code builds.

Looks correct to me. The staging ones will be "depreciated" and will
age out over 2 kernel releases unless someone objects.
As this is just a lot of code movement, it probably makes more sense for
me to do this myself, right?
thanks for getting all of this together.

Depends on whether you want a git tree or full patches for this.
I'd prefer not doing it myself, if you already offer to do it.
I guess the hardest part is splitting the Makefile and Kconfig
files appropriately. I've done that mostly for the first version,
so you should probably start from there and move it around some
more, splitting out the staging parts.

Ok, I'll do it this weekend. I have a 12 hour plane ride so I need
something to do on it...

I thought we wanted to keep serial167 alive as long as it builds?

Does it build ? Is it secure ? I was under the impression the answer in
both cases was no.

serial167 builds fine.
Your second question is more difficult to answer, though ;-)

Ok, here's 2 patches that just does these two things.
Does it look correct? For the second patch, shoudl I really be moving
the defkeymap and keyboard and selection files as well?
thoughts?

The tty code should be at the root of the tree, as everyone
needs it, and it's always built, and it's not really a "driver"

IMHO the CONFIG_CONSOLE_TRANSLATIONS stuff belongs in the same directory
as the VT driver, because it is only used in VT. It also puts all teh
unusual Makefile bits into one place.

My original patch also moved pty.o, sysrq.o and the n_*.o line disciplines.
It's probably debatable where the line disciplines should go (I don't care
much, so don't ask me), but pty and sysrq seem like they should really
be part of the tty core directory.

Ok, I've now moved the rest of these files in the tty-next tree, so we
should be completed with this for .39.
If there are any problems, or I missed any files, please let me know.
