broken devfs-support in SGI Zilog8530 serial driver

broken devfs-support in SGI Zilog8530 serial driver

Hi,

I'm not sure if this is a devfs or mips problem so I'm sending it
to both lists.

I just compiled my own mips-kernel from oss.sgi.com:/cvs to get
devfs-support. Unfortunately there seems to be a problem with the
serial-driver at least in the linux_2_4 branch:

SGI Zilog8530 serial driver version 1.00
devfs_register(ttyS): could not append to parent, err: -17
devfs_register(cua): could not append to parent, err: -17
tty00 at 0xbfbd9830 (irq = 29) is a Zilog8530
tty01 at 0xbfbd9838 (irq = 29) is a Zilog8530

The result is that the directories /dev/tts and /dev/cua are missing.

There are only the files /dev/ttS and /dev/cua which can be used to get
access to the first serial port.

I have attached the full dmesg output at the end.

Regards

Raoul

This means that somebody else registered ttyS (and cua) before Zilog8530
driver attempted to do it. The possible reason could be that driver
calls tty_register_devfs itself in this case it must set
TTY_DRIVER_NO_DEVFS flag to prevent the same nodes registered by
tty_register_driver.

Yeah, but I think the serial ports should be placed under /dev/tts/* and
/dev/cua/*, shouldn't they?

Which driver could have registered /dev/ttyS? if I search the
kernel-sources under arch/mips I get

but I have not compiled support for arc console (when do you need that
btw?) and all other drivers do not apply to IP22 AFAIK.

My .config is attached below.

Re: broken devfs-support in SGI Zilog8530 serial driver

[Russell Coker]

You need some code similar to the following in the serial driver:

#ifdef CONFIG_DEVFS_FS
        serial_driver.name = "tts/%d";
#else
        serial_driver.name = "ttyS";
#endif

Of course if the original device nodes were named /dev/ttyZ0 etc then you 
want "tts/Z%d".

Look at the Cyclades and Stallion drivers for examples of it being done 
correctly.  Or tell me exactly the details of what you want and I'll send you 
a patch.

At this time we don't even claim to have proper devfs support in the
Indy serial drivers ...

But it would be nice to have ;-)

Especially because you only need the small change pointed out by

It works for my Indy and I just love devfs. All other drivers used
on my box also work fine with devfs (sound, watchdog, rtc etc.).

Thanks for including the changes fr the ttyS's. But it seems you forgot the
callout-devices:

That's what you get for submitting patches that don't apply ;)  Did you do
cut'n'paste or similiar cruelties to that poor little patch?

I thought the callout devices are officially "dead" and should disappear
"Real Soon Now(tm)" as beeing a locking hell and unneeded.

Really Soon Now doesn't mean what you want it to mean in a world that is
driven by backward compatibility ...
