[kernel 2.6] Patch for mxser.c driver

[kernel 2.6] Patch for mxser.c driver

[Bernard Pidoux]

Hi,

mxser driver in kernel 2.6.16 can compile but it does not drive the 
serial multiport adapter from Moxa.

According to Moxa documentation for version 1.8, msmknod script, 
downloaded from their support site, creates ttyM0-7 and cum0-7 tty 
devices with major numbers 30 and 35 by defaults.

However, in mxser.c major device numbers are still 174 and 175.

Here is a patch to change major tty device numbers to proper default values.

Anyway, it should be /proc/devices dependent.

NAK

mxser.c is not the Moxa intellio card support, it is SmartIO/IndustIO
support. The IntellIO is different and no longer supported in 2.6

Re: [kernel 2.6] Patch for mxser.c driver

[Bernard Pidoux]

Hi,

The multiport serial adapter I wanted to use is a four ports C104H/PCI 
SmartIO.

I just received from Moxa support a beta version of the driver 
(mxser_1.9.1.tgz).

Acording to readme.txt file

    The Smartio/Industio/UPCI family Linux driver supports following 
multiport
    boards.

     - 2 ports multiport board
         CP-102U, CP-102UL
         CP-132U-I, CP-132UL,
         CP-132, CP-132I, CP132S, CP-132IS,
         CI-132, CI-132I, CI-132IS,
         (C102H, C102HI, C102HIS, C102P, CP-102, CP-102S)

     - 4 ports multiport board
         CP-104EL,
         CP-104UL, CP-104JU,
         CP-134U, CP-134U-I
         C104H/PCI, C104HS/PCI,
         CP-114, CP-114I, CP-114S, CP-114IS,
         C104H, C104HS,
         CI-104J, CI-104JS
         CI-134, CI-134I, CI-134IS,
         (C114HI, CT-114I, C104P)

     - 8 ports multiport board
         CP-118EL, CP-168EL,
         CP-118U, CP-168U,
         C168H/PCI,
         C168H, C168HS,
         (C168P)

I did not have any problem to compile this beta version of driver 1.9 
and utilities under kernel 2.6.16 with gcc 4.0.3

Could you send me a copy, or publish on the Net?

Thanks for sources. The problem is, they still use deprecated api, they still
pci_find_device, despite I applied them to correct it and they promise to at
least try their best, unfortunately with no effect :(. I guess, if they don't
convert it to pci probing, the driver won't be altered (delete 'if LINUXVERSION'
and so on) to be re-merged as a new version.
The driver needs to be rewritten as a whole (macros, whitespace, probing, maybe
it missed some new tty api changes and so on). Maybe I get into that on summer
holidays or somebody may do so earlier, but merging driver in present state is
maybe unwanted.

Far better would be to diff their old driver and their new driver then
import the changes into the Linux driver proper. 

I've got their December 2004 driver (the one we originally worked from)
as an archive here if someone wants to do the work. Some of their later
changes did get imported but not all.
