Staging/IIO patches for 5.6-rc1
Here is the big staging/iio driver patches for 5.6-rc1
Included in here are:
- lots of new IIO drivers and updates for that subsystem
- the usual huge quantity of minor cleanups for staging drivers
- removal of the following staging drivers:
- isdn/avm
- isdn/gigaset
- isdn/hysdn
- octeon-usb
- octeon ethernet
Overall we deleted far more lines than we added, removing over 40k of
old and obsolete driver code.
All of these changes have been in linux-next for a while with no
reported issues.

Description:
|
||||||
|
DMA buffers tend to have a alignment requirement for the
|
||||||
|
buffers. If this alignment requirement is not met samples might
|
||||||
|
be dropped from the buffer.
|
||||||
|
|
||||||
|
This property reports the alignment requirements in bytes.
|
||||||
|
This means that the buffer size in bytes needs to be a integer
|
||||||
|
multiple of the number reported by this file.
|
||||||
|
|
||||||
|
The alignment requirements in number of sample sets will depend
|
||||||
|
on the enabled channels and the bytes per channel. This means
|
||||||
|
that the alignment requirement in samples sets might change
|
||||||
|
depending on which and how many channels are enabled. Whereas
|
||||||
|
the alignment requirement reported in bytes by this property
|
||||||
|
will remain static and does not depend on which channels are
|
||||||
|
enabled.

Bit-banging driver using one GPIO:
|
||||||
|
- ping-gpios is raised by the driver to start measurement
|
||||||
|
- direction of ping-gpio is then switched into input with an interrupt
|
||||||
|
for receiving distance value as PWM signal
|
||||||
|
|
||||||

Definition of the GPIO for the triggering and echo (output and input)
|
||||||
|
This GPIO is set for about 5 us by the driver to tell the device it
|
||||||
|
should initiate the measurement cycle. Afterwards the GPIO is switched
|
||||||
|
to input direction with an interrupt. The device sets it and the
|
||||||
|
length of the input signal corresponds to the measured distance.
|
||||||
|
It needs to be an GPIO which is able to deliver an interrupt because
|
||||||
|
the time between two interrupts is measured in the driver.
|
||||||
|
See Documentation/devicetree/bindings/gpio/gpio.txt for information
|
||||||
|
on how to specify a consumer gpio.

Driver for active AVM Controller
|
|
||||||
================================
|
|
||||||
|
|
||||||
The driver provides a kernel capi2.0 Interface (kernelcapi) and
|
|
||||||
on top of this a User-Level-CAPI2.0-interface (capi)
|
|
||||||
and a driver to connect isdn4linux with CAPI2.0 (capidrv).
|
|
||||||
The lowlevel interface can be used to implement a CAPI2.0
|
|
||||||
also for passive cards since July 1999.
|
|
||||||
|
|
||||||
The author can be reached at calle@calle.in-berlin.de.
|
|
||||||
The command avmcapictrl is part of the isdn4k-utils.
|
|
||||||
t4-files can be found at ftp://ftp.avm.de/cardware/b1/linux/firmware
|
|
||||||
|
|
||||||
Currently supported cards:
|
|
||||||
|
|
||||||
- B1 ISA (all versions)
|
|
||||||
- B1 PCI
|
|
||||||
- T1/T1B (HEMA card)
|
|
||||||
- M1
|
|
||||||
- M2
|
|
||||||
- B1 PCMCIA
|
|
||||||
|
|
||||||
Installing
|
|
||||||
----------
|
|
||||||
|
|
||||||
You need at least /dev/capi20 to load the firmware.
|
|
||||||
|
|
||||||
::
|
|
||||||
|
|
||||||
mknod /dev/capi20 c 68 0
|
|
||||||
mknod /dev/capi20.00 c 68 1
|
|
||||||
mknod /dev/capi20.01 c 68 2
|
|
||||||
.
|
|
||||||
.
|
|
||||||
.
|
|
||||||
mknod /dev/capi20.19 c 68 20
|
|
||||||
|
|
||||||
Running
|
|
||||||
-------
|
|
||||||
|
|
||||||
To use the card you need the t4-files to download the firmware.
|
|
||||||
AVM GmbH provides several t4-files for the different D-channel
|
|
||||||
protocols (b1.t4 for Euro-ISDN). Install these file in /lib/isdn.
|
|
||||||
|
|
||||||
if you configure as modules load the modules this way::
|
|
||||||
|
|
||||||
insmod /lib/modules/current/misc/capiutil.o
|
|
||||||
insmod /lib/modules/current/misc/b1.o
|
|
||||||
insmod /lib/modules/current/misc/kernelcapi.o
|
|
||||||
insmod /lib/modules/current/misc/capidrv.o
|
|
||||||
insmod /lib/modules/current/misc/capi.o
|
|
||||||
|
|
||||||
if you have an B1-PCI card load the module b1pci.o::
|
|
||||||
|
|
||||||
insmod /lib/modules/current/misc/b1pci.o
|
|
||||||
|
|
||||||
and load the firmware with::
|
|
||||||
|
|
||||||
avmcapictrl load /lib/isdn/b1.t4 1
|
|
||||||
|
|
||||||
if you have an B1-ISA card load the module b1isa.o
|
|
||||||
and add the card by calling::
|
|
||||||
|
|
||||||
avmcapictrl add 0x150 15
|
|
||||||
|
|
||||||
and load the firmware by calling::
|
|
||||||
|
|
||||||
avmcapictrl load /lib/isdn/b1.t4 1
|
|
||||||
|
|
||||||
if you have an T1-ISA card load the module t1isa.o
|
|
||||||
and add the card by calling::
|
|
||||||
|
|
||||||
avmcapictrl add 0x450 15 T1 0
|
|
||||||
|
|
||||||
and load the firmware by calling::
|
|
||||||
|
|
||||||
avmcapictrl load /lib/isdn/t1.t4 1
|
|
||||||
|
|
||||||
if you have an PCMCIA card (B1/M1/M2) load the module b1pcmcia.o
|
|
||||||
before you insert the card.

Init card and load firmware.
|
|
||||||
|
|
||||||
For an D64S use "FV: 1" as phone number
|
|
||||||
|
|
||||||
For an D64S2 use "FV: 1" and "FV: 2" for multilink
|
|
||||||
or "FV: 1,2" to use CAPI channel bundling.

|
||||||
We had also reports from users of Gigaset M105 who could use the drivers
|
|
||||||
with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.5.)
|
|
||||||
If you have another device that works with our driver, please let us know.
|
|
||||||
|
|
||||||
Chances of getting an USB device to work are good if the output of::
|
|
||||||
|
|
||||||
lsusb
|
|
||||||
|
|
||||||
at the command line contains one of the following::
|
|
||||||
|
|
||||||
ID 0681:0001
|
|
||||||
ID 0681:0002
|
|
||||||
ID 0681:0009
|
|
||||||
ID 0681:0021
|
|
||||||
ID 0681:0022
|
|
||||||
|
|
||||||
1.2. Software
|
|
||||||
-------------
|
|
||||||
|
|
||||||
The driver works with the Kernel CAPI subsystem and can be used with any
|
|
||||||
software which is able to use CAPI 2.0 for ISDN connections (voice or data).
|
|
||||||
|
|
||||||
There are some user space tools available at
|
|
||||||
https://sourceforge.net/projects/gigaset307x/
|
|
||||||
which provide access to additional device specific functions like SMS,
|
|
||||||
phonebook or call journal.
|
|
||||||
|
|
||||||
|
|
||||||
2. How to use the driver
|
|
||||||
==========================
|
|
||||||
|
|
||||||
2.1. Modules
|
|
||||||
------------
|
|
||||||
|
|
||||||
For the devices to work, the proper kernel modules have to be loaded.
|
|
||||||
This normally happens automatically when the system detects the USB
|
|
||||||
device (base, M105) or when the line discipline is attached (M101). It
|
|
||||||
can also be triggered manually using the modprobe(8) command, for example
|
|
||||||
for troubleshooting or to pass module parameters.
|
|
||||||
|
|
||||||
The module ser_gigaset provides a serial line discipline N_GIGASET_M101
|
|
||||||
which uses the regular serial port driver to access the device, and must
|
|
||||||
therefore be attached to the serial device to which the M101 is connected.
|
|
||||||
The ldattach(8) command (included in util-linux-ng release 2.14 or later)
|
|
||||||
can be used for that purpose, for example::
|
|
||||||
|
|
||||||
ldattach GIGASET_M101 /dev/ttyS1
|
|
||||||
|
|
||||||
This will open the device file, attach the line discipline to it, and
|
|
||||||
then sleep in the background, keeping the device open so that the line
|
|
||||||
discipline remains active. To deactivate it, kill the daemon, for example
|
|
||||||
with::
|
|
||||||
|
|
||||||
killall ldattach
|
|
||||||
|
|
||||||
before disconnecting the device. To have this happen automatically at
|
|
||||||
system startup/shutdown on an LSB compatible system, create and activate
|
|
||||||
an appropriate LSB startup script /etc/init.d/gigaset. (The init name
|
|
||||||
'gigaset' is officially assigned to this project by LANANA.)
|
|
||||||
Alternatively, just add the 'ldattach' command line to /etc/rc.local.
|
|
||||||
|
|
||||||
The modules accept the following parameters:
|
|
||||||
|
|
||||||
=============== ========== ==========================================
|
|
||||||
Module Parameter Meaning
|
|
||||||
|
|
||||||
gigaset debug debug level (see section 3.2.)
|
|
||||||
|
|
||||||
startmode initial operation mode (see section 2.5.):
|
|
||||||
bas_gigaset ) 1=CAPI (default), 0=Unimodem
|
|
||||||
ser_gigaset )
|
|
||||||
usb_gigaset ) cidmode initial Call-ID mode setting (see section
|
|
||||||
2.5.): 1=on (default), 0=off
|
|
||||||
|
|
||||||
=============== ========== ==========================================
|
|
||||||
|
|
||||||
Depending on your distribution you may want to create a separate module
|
|
||||||
configuration file like /etc/modprobe.d/gigaset.conf for these.
|
|
||||||
|
|
||||||
2.2. Device nodes for user space programs
|
|
||||||
-----------------------------------------
|
|
||||||
|
|
||||||
The device can be accessed from user space (eg. by the user space tools
|
|
||||||
mentioned in 1.2.) through the device nodes:
|
|
||||||
|
|
||||||
- /dev/ttyGS0 for M101 (RS232 data boxes)
|
|
||||||
- /dev/ttyGU0 for M105 (USB data boxes)
|
|
||||||
- /dev/ttyGB0 for the base driver (direct USB connection)
|
|
||||||
|
|
||||||
If you connect more than one device of a type, they will get consecutive
|
|
||||||
device nodes, eg. /dev/ttyGU1 for a second M105.
|
|
||||||
|
|
||||||
You can also set a "default device" for the user space tools to use when
|
|
||||||
no device node is given as parameter, by creating a symlink /dev/ttyG to
|
|
||||||
one of them, eg.::
|
|
||||||
|
|
||||||
ln -s /dev/ttyGB0 /dev/ttyG
|
|
||||||
|
|
||||||
The devices accept the following device specific ioctl calls
|
|
||||||
(defined in gigaset_dev.h):
|
|
||||||
|
|
||||||
``ioctl(int fd, GIGASET_REDIR, int *cmd);``
|
|
||||||
|
|
||||||
If cmd==1, the device is set to be controlled exclusively through the
|
|
||||||
character device node; access from the ISDN subsystem is blocked.
|
|
||||||
|
|
||||||
If cmd==0, the device is set to be used from the ISDN subsystem and does
|
|
||||||
not communicate through the character device node.
|
|
||||||
|
|
||||||
``ioctl(int fd, GIGASET_CONFIG, int *cmd);``
|
|
||||||
|
|
||||||
(ser_gigaset and usb_gigaset only)
|
|
||||||
|
|
||||||
If cmd==1, the device is set to adapter configuration mode where commands
|
|
||||||
are interpreted by the M10x DECT adapter itself instead of being
|
|
||||||
forwarded to the base station. In this mode, the device accepts the
|
|
||||||
commands described in Siemens document "AT-Kommando Alignment M10x Data"
|
|
||||||
for setting the operation mode, associating with a base station and
|
|
||||||
querying parameters like field strengh and signal quality.
|
|
||||||
|
|
||||||
Note that there is no ioctl command for leaving adapter configuration
|
|
||||||
mode and returning to regular operation. In order to leave adapter
|
|
||||||
configuration mode, write the command ATO to the device.
|
|
||||||
|
|
||||||
``ioctl(int fd, GIGASET_BRKCHARS, unsigned char brkchars[6]);``
|
|
||||||
|
|
||||||
(usb_gigaset only)
|
|
||||||
|
|
||||||
Set the break characters on an M105's internal serial adapter to the six
|
|
||||||
bytes stored in brkchars[]. Unused bytes should be set to zero.
|
|
||||||
|
|
||||||
ioctl(int fd, GIGASET_VERSION, unsigned version[4]);
|
|
||||||
Retrieve version information from the driver. version[0] must be set to
|
|
||||||
one of:
|
|
||||||
|
|
||||||
- GIGVER_DRIVER: retrieve driver version
|
|
||||||
- GIGVER_COMPAT: retrieve interface compatibility version
|
|
||||||
- GIGVER_FWBASE: retrieve the firmware version of the base
|
|
||||||
|
|
||||||
Upon return, version[] is filled with the requested version information.
|
|
||||||
|
|
||||||
2.3. CAPI
|
|
||||||
---------
|
|
||||||
|
|
||||||
The devices will show up as CAPI controllers as soon as the
|
|
||||||
corresponding driver module is loaded, and can then be used with
|
|
||||||
CAPI 2.0 kernel and user space applications. For user space access,
|
|
||||||
the module capi.ko must be loaded.
|
|
||||||
|
|
||||||
Most distributions handle loading and unloading of the various CAPI
|
|
||||||
modules automatically via the command capiinit(1) from the capi4k-utils
|
|
||||||
package or a similar mechanism. Note that capiinit(1) cannot unload the
|
|
||||||
Gigaset drivers because it doesn't support more than one module per
|
|
||||||
driver.
|
|
||||||
|
|
||||||
2.5. Unimodem mode
|
|
||||||
------------------
|
|
||||||
|
|
||||||
In this mode the device works like a modem connected to a serial port
|
|
||||||
(the /dev/ttyGU0, ... mentioned above) which understands the commands::
|
|
||||||
|
|
||||||
ATZ init, reset
|
|
||||||
=> OK or ERROR
|
|
||||||
ATD
|
|
||||||
ATDT dial
|
|
||||||
=> OK, CONNECT,
|
|
||||||
BUSY,
|
|
||||||
NO DIAL TONE,
|
|
||||||
NO CARRIER,
|
|
||||||
NO ANSWER
|
|
||||||
<pause>+++<pause> change to command mode when connected
|
|
||||||
ATH hangup
|
|
||||||
|
|
||||||
You can use some configuration tool of your distribution to configure this
|
|
||||||
"modem" or configure pppd/wvdial manually. There are some example ppp
|
|
||||||
configuration files and chat scripts in the gigaset-VERSION/ppp directory
|
|
||||||
in the driver packages from https://sourceforge.net/projects/gigaset307x/.
|
|
||||||
Please note that the USB drivers are not able to change the state of the
|
|
||||||
control lines. This means you must use "Stupid Mode" if you are using
|
|
||||||
wvdial or you should use the nocrtscts option of pppd.
|
|
||||||
You must also assure that the ppp_async module is loaded with the parameter
|
|
||||||
flag_time=0. You can do this e.g. by adding a line like::
|
|
||||||
|
|
||||||
options ppp_async flag_time=0
|
|
||||||
|
|
||||||
to an appropriate module configuration file, like::
|
|
||||||
|
|
||||||
/etc/modprobe.d/gigaset.conf.
|
|
||||||
|
|
||||||
Unimodem mode is needed for making some devices [e.g. SX100] work which
|
|
||||||
do not support the regular Gigaset command set. If debug output (see
|
|
||||||
section 3.2.) shows something like this when dialing::
|
|
||||||
|
|
||||||
CMD Received: ERROR
|
|
||||||
Available Params: 0
|
|
||||||
Connection State: 0, Response: -1
|
|
||||||
gigaset_process_response: resp_code -1 in ConState 0 !
|
|
||||||
Timeout occurred
|
|
||||||
|
|
||||||
then switching to unimodem mode may help.
|
|
||||||
|
|
||||||
If you have installed the command line tool gigacontr, you can enter
|
|
||||||
unimodem mode using::
|
|
||||||
|
|
||||||
gigacontr --mode unimodem
|
|
||||||
|
|
||||||
You can switch back using::
|
|
||||||
|
|
||||||
gigacontr --mode isdn
|
|
||||||
|
|
||||||
You can also put the driver directly into Unimodem mode when it's loaded,
|
|
||||||
by passing the module parameter startmode=0 to the hardware specific
|
|
||||||
module, e.g.::
|
|
||||||
|
|
||||||
modprobe usb_gigaset startmode=0
|
|
||||||
|
|
||||||
or by adding a line like::
|
|
||||||
|
|
||||||
options usb_gigaset startmode=0
|
|
||||||
|
|
||||||
to an appropriate module configuration file, like::
|
|
||||||
|
|
||||||
/etc/modprobe.d/gigaset.conf
|
|
||||||
|
|
||||||
2.6. Call-ID (CID) mode
|
|
||||||
-----------------------
|
|
||||||
|
|
||||||
Call-IDs are numbers used to tag commands to, and responses from, the
|
|
||||||
Gigaset base in order to support the simultaneous handling of multiple
|
|
||||||
ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem
|
|
||||||
mode"). Without Call-IDs (in Unimodem mode), only a very limited set of
|
|
||||||
functions is available. It allows outgoing data connections only, but
|
|
||||||
does not signal incoming calls or other base events.
|
|
||||||
|
|
||||||
DECT cordless data devices (M10x) permanently occupy the cordless
|
|
||||||
connection to the base while Call-IDs are activated. As the Gigaset
|
|
||||||
bases only support one DECT data connection at a time, this prevents
|
|
||||||
other DECT cordless data devices from accessing the base.
|
|
||||||
|
|
||||||
During active operation, the driver switches to the necessary mode
|
|
||||||
automatically. However, for the reasons above, the mode chosen when
|
|
||||||
the device is not in use (idle) can be selected by the user.
|
|
||||||
|
|
||||||
- If you want to receive incoming calls, you can use the default
|
|
||||||
settings (CID mode).
|
|
||||||
- If you have several DECT data devices (M10x) which you want to use
|
|
||||||
in turn, select Unimodem mode by passing the parameter "cidmode=0" to
|
|
||||||
the appropriate driver module (ser_gigaset or usb_gigaset).
|
|
||||||
|
|
||||||
If you want both of these at once, you are out of luck.
|
|
||||||
|
|
||||||
You can also use the tty class parameter "cidmode" of the device to
|
|
||||||
change its CID mode while the driver is loaded, eg.::
|
|
||||||
|
|
||||||
echo 0 > /sys/class/tty/ttyGU0/cidmode
|
|
||||||
|
|
||||||
2.7. Dialing Numbers
|
|
||||||
--------------------
|
|
||||||
provided by an application for dialing out must
|
|
||||||
be a public network number according to the local dialing plan, without
|
|
||||||
any dial prefix for getting an outside line.
|
|
||||||
|
|
||||||
Internal calls can be made by providing an internal extension number
|
|
||||||
prefixed with ``**`` (two asterisks) as the called party number. So to dial
|
|
||||||
eg. the first registered DECT handset, give ``**11`` as the called party
|
|
||||||
number. Dialing ``***`` (three asterisks) calls all extensions
|
|
||||||
simultaneously (global call).
|
|
||||||
|
|
||||||
Unimodem mode does not support internal calls.
|
|
||||||
|
|
||||||
2.8. Unregistered Wireless Devices (M101/M105)
|
|
||||||
----------------------------------------------
|
|
||||||
|
|
||||||
The main purpose of the ser_gigaset and usb_gigaset drivers is to allow
|
|
||||||
the M101 and M105 wireless devices to be used as ISDN devices for ISDN
|
|
||||||
connections through a Gigaset base. Therefore they assume that the device
|
|
||||||
is registered to a DECT base.
|
|
||||||
|
|
||||||
If the M101/M105 device is not registered to a base, initialization of
|
|
||||||
the device fails, and a corresponding error message is logged by the
|
|
||||||
driver. In that situation, a restricted set of functions is available
|
|
||||||
which includes, in particular, those necessary for registering the device
|
|
||||||
to a base or for switching it between Fixed Part and Portable Part
|
|
||||||
modes. See the gigacontr(8) manpage for details.
|
|
||||||
|
|
||||||
3. Troubleshooting
|
|
||||||
====================
|
|
||||||
|
|
||||||
3.1. Solutions to frequently reported problems
|
|
||||||
----------------------------------------------
|
|
||||||
|
|
||||||
Problem:
|
|
||||||
You have a slow provider and isdn4linux gives up dialing too early.
|
|
||||||
Solution:
|
|
||||||
Load the isdn module using the dialtimeout option. You can do this e.g.
|
|
||||||
by adding a line like::
|
|
||||||
|
|
||||||
options isdn dialtimeout=15
|
|
||||||
|
|
||||||
to /etc/modprobe.d/gigaset.conf or a similar file.
|
|
||||||
|
|
||||||
Problem:
|
|
||||||
The isdnlog program emits error messages or just doesn't work.
|
|
||||||
Solution:
|
|
||||||
Isdnlog supports only the HiSax driver. Do not attempt to use it with
|
|
||||||
other drivers such as Gigaset.
|
|
||||||
|
|
||||||
Problem:
|
|
||||||
You have two or more DECT data adapters (M101/M105) and only the
|
|
||||||
first one you turn on works.
|
|
||||||
Solution:
|
|
||||||
Select Unimodem mode for all DECT data adapters. (see section 2.5.)
|
|
||||||
|
|
||||||
Problem:
|
|
||||||
Messages like this::
|
|
||||||
|
|
||||||
usb_gigaset 3-2:1.0: Could not initialize the device.
|
|
||||||
|
|
||||||
appear in your syslog.
|
|
||||||
Solution:
|
|
||||||
Check whether your M10x wireless device is correctly registered to the
|
|
||||||
Gigaset base. (see section 2.7.)
|
|
||||||
|
|
||||||
3.2. Telling the driver to provide more information
|
|
||||||
---------------------------------------------------
|
|
||||||
Building the driver with the "Gigaset debugging" kernel configuration
|
|
||||||
option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional
|
|
||||||
information useful for debugging.
|
|
||||||
|
|
||||||
You can control the amount of debugging information the driver produces by
|
|
||||||
writing an appropriate value to /sys/module/gigaset/parameters/debug,
|
|
||||||
e.g.::
|
|
||||||
|
|
||||||
echo 0 > /sys/module/gigaset/parameters/debug
|
|
||||||
|
|
||||||
switches off debugging output completely,
|
|
||||||
|
|
||||||
::
|
|
||||||
|
|
||||||
echo 0x302020 > /sys/module/gigaset/parameters/debug
|
|
||||||
|
|
||||||
enables a reasonable set of debugging output messages. These values are
|
|
||||||
bit patterns where every bit controls a certain type of debugging output.
|
|
||||||
See the constants DEBUG_* in the source file gigaset.h for details.
|
|
||||||
|
|
||||||
The initial value can be set using the debug parameter when loading the
|
|
||||||
module "gigaset", e.g. by adding a line::
|
|
||||||
|
|
||||||
options gigaset debug=0
|
|
||||||
|
|
||||||
to your module configuration file, eg. /etc/modprobe.d/gigaset.conf
|
|
||||||
|
|
||||||
Generated debugging information can be found
|
|
||||||
- as output of the command::
|
|
||||||
|
|
||||||
dmesg
|
|
||||||
|
|
||||||
- in system log files written by your syslog daemon, usually
|
|
||||||
in /var/log/, e.g. /var/log/messages.
|
|
||||||
|
|
||||||
3.3. Reporting problems and bugs
|
|
||||||
--------------------------------
|
|
||||||
If you can't solve problems with the driver on your own, feel free to
|
|
||||||
use one of the forums, bug trackers, or mailing lists on
|
|
||||||
|
|
||||||
https://sourceforge.net/projects/gigaset307x
|
|
||||||
|
|
||||||
or write an electronic mail to the maintainers.
|
|
||||||
|
|
||||||
Try to provide as much information as possible, such as
|
|
||||||
|
|
||||||
- distribution
|
|
||||||
- kernel version (uname -r)
|
|
||||||
- gcc version (gcc --version)
|
|
||||||
- hardware architecture (uname -m, ...)
|
|
||||||
- type and firmware version of your device (base and wireless module,
|
|
||||||
if any)
|
|
||||||
- output of "lsusb -v" (if using an USB device)
|
|
||||||
- error messages
|
|
||||||
- relevant system log messages (it would help if you activate debug
|
|
||||||
output as described in 3.2.)
|
|
||||||
|
|
||||||
For help with general configuration problems not specific to our driver,
|
|
||||||
such as isdn4linux and network configuration issues, please refer to the
|
|
||||||
appropriate forums and newsgroups.
|
|
||||||
|
|
||||||
3.4. Reporting problem solutions
|
|
||||||
--------------------------------
|
|
||||||
If you solved a problem with our drivers, wrote startup scripts for your
|
|
||||||
distribution, ... feel free to contact us (using one of the places
|

1. About the driver
|
|
||||||
===================
|
|
||||||
|
|
||||||
The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active
|
|
||||||
PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
|
|
||||||
enable ISDN support in the kernel config and support for HYSDN cards in
|
|
||||||
the active cards submenu. The driver may only be compiled and used if
|
|
||||||
support for loadable modules and the process filesystem have been enabled.
|
|
||||||
|
|
||||||
These cards provide two different interfaces to the kernel. Without the
|
|
||||||
optional CAPI 2.0 support, they register as ethernet card. IP-routing
|
|
||||||
to a ISDN-destination is performed on the card itself. All necessary
|
|
||||||
handlers for various protocols like ppp and others as well as config info
|
|
||||||
and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
|
|
||||||
|
|
||||||
With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0
|
|
||||||
compliant devices with either CAPI 2.0 applications
|
|
||||||
(check isdn4k-utils) or -using the capidrv module- as a regular
|
|
||||||
isdn4linux device. This is done via the same mechanism as with the
|
|
||||||
active AVM cards and in fact uses the same module.
|
|
||||||
|
|
||||||
|
|
||||||
2. Loading/Unloading the driver
|
|
||||||
===============================
|
|
||||||
|
|
||||||
The module has no command line parameters and auto detects up to 10 cards
|
|
||||||
in the id-range 0-9.
|
|
||||||
If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
|
|
||||||
subdir need to be closed and all ethernet interfaces allocated by this
|
|
||||||
driver must be shut down. Otherwise the module counter will avoid a module
|
|
||||||
unload.
|
|
||||||
|
|
||||||
If you are using the CAPI 2.0-interface, make sure to load/modprobe the
|
|
||||||
kernelcapi-module first.
|
|
||||||
|
|
||||||
If you plan to use the capidrv-link to isdn4linux, make sure to load
|
|
||||||
capidrv.o after all modules using this driver (i.e. after hysdn and
|
|
||||||
any avm-specific modules).
|
|
||||||
|
|
||||||
3. Entries in the /proc filesystem
|
|
||||||
==================================
|
|
||||||
|
|
||||||
When the module has been loaded it adds the directory hysdn in the
|
|
||||||
/proc/net tree. This directory contains exactly 2 file entries for each
|
|
||||||
card. One is called cardconfX and the other cardlogX, where X is the
|
|
||||||
card id number from 0 to 9.
|
|
||||||
The cards are numbered in the order found in the PCI config data.
|
|
||||||
|
|
||||||
4. The /proc/net/hysdn/cardconfX file
|
|
||||||
=====================================
|
|
||||||
|
|
||||||
This file may be read to get by everyone to get info about the cards type,
|
|
||||||
actual state, available features and used resources.
|
|
||||||
The first 3 entries (id, bus and slot) are PCI info fields, the following
|
|
||||||
type field gives the information about the cards type:
|
|
||||||
|
|
||||||
- 4 -> Ergo card (server card with 2 b-chans)
|
|
||||||
- 5 -> Metro card (server card with 4 or 8 b-chans)
|
|
||||||
- 6 -> Champ card (client card with 2 b-chans)
|
|
||||||
|
|
||||||
The following 3 fields show the hardware assignments for irq, iobase and the
|
|
||||||
dual ported memory (dp-mem).
|
|
||||||
|
|
||||||
The fields b-chans and fax-chans announce the available card resources of
|
|
||||||
this types for the user.
|
|
||||||
|
|
||||||
The state variable indicates the actual drivers state for this card with the
|
|
||||||
following assignments.
|
|
||||||
|
|
||||||
- 0 -> card has not been booted since driver load
|
|
||||||
- 1 -> card booting is actually in progess
|
|
||||||
- 2 -> card is in an error state due to a previous boot failure
|
|
||||||
- 3 -> card is booted and active
|
|
||||||
|
|
||||||
And the last field (device) shows the name of the ethernet device assigned
|
|
||||||
to this card. Up to the first successful boot this field only shows a -
|
|
||||||
to tell that no net device has been allocated up to now. Once a net device
|
|
||||||
has been allocated it remains assigned to this card, even if a card is
|
|
||||||
rebooted and an boot error occurs.
|
|
||||||
|
|
||||||
Writing to the cardconfX file boots the card or transfers config lines to
|
|
||||||
the cards firmware. The type of data is automatically detected when the
|
|
||||||
first data is written. Only root has write access to this file.
|
|
||||||
The firmware boot files are normally called hyclient.pof for client cards
|
|
||||||
and hyserver.pof for server cards.
|
|
||||||
After successfully writing the boot file, complete config files or single
|
|
||||||
config lines may be copied to this file.
|
|
||||||
If an error occurs the return value given to the writing process has the
|
|
||||||
following additional codes (decimal):
|
|
||||||
|
|
||||||
==== ============================================
|
|
||||||
1000 Another process is currently bootng the card
|
|
||||||
1001 Invalid firmware header
|
|
||||||
1002 Boards dual-port RAM test failed
|
|
||||||
1003 Internal firmware handler error
|
|
||||||
1004 Boot image size invalid
|
|
||||||
1005 First boot stage (bootstrap loader) failed
|
|
||||||
1006 Second boot stage failure
|
|
||||||
1007 Timeout waiting for card ready during boot
|
|
||||||
1008 Operation only allowed in booted state
|
|
||||||
1009 Config line too long
|
|
||||||
1010 Invalid channel number
|
|
||||||
1011 Timeout sending config data
|
|
||||||
==== ============================================
|
|
||||||
|
|
||||||
Additional info about error reasons may be fetched from the log output.
|
|
||||||
|
|
||||||
5. The /proc/net/hysdn/cardlogX file
|
|
||||||
====================================
|
|
||||||
|
|
||||||
The cardlogX file entry may be opened multiple for reading by everyone to
|
|
||||||
get the cards and drivers log data. Card messages always start with the
|
|
||||||
keyword LOG. All other lines are output from the driver.
|
|
||||||
The driver log data may be redirected to the syslog by selecting the
|
|
||||||
appropriate bitmask. The cards log messages will always be send to this
|
|
||||||
interface but never to the syslog.
|
|
||||||
|
|
||||||
A root user may write a decimal or hex (with 0x) value t this file to select
|
|
||||||
desired output options. As mentioned above the cards log dat is always
|
|
||||||
written to the cardlog file independent of the following options only used
|
|
||||||
to check and debug the driver itself:
|
|
||||||
|
|
||||||
For example::
|
|
||||||
|
|
||||||
echo "0x34560078" > /proc/net/hysdn/cardlog0
|
|
||||||
|
|
||||||
to output the hex log mask 34560078 for card 0.
|
|
||||||
|
|
||||||
The written value is regarded as an unsigned 32-Bit value, bit ored for
|
|
||||||
desired output. The following bits are already assigned:
|
|
||||||
|
|
||||||
========== ============================================================
|
|
||||||
0x80000000 All driver log data is alternatively via syslog
|
|
||||||
0x00000001 Log memory allocation errors
|
|
||||||
0x00000010 Firmware load start and close are logged
|
|
||||||
0x00000020 Log firmware record parser
|
|
||||||
0x00000040 Log every firmware write actions
|
|
||||||
0x00000080 Log all card related boot messages
|
|
||||||
0x00000100 Output all config data sent for debugging purposes
|
|
||||||
0x00000200 Only non comment config lines are shown wth channel
|
|
||||||
0x00000400 Additional conf log output
|
|
||||||
0x00001000 Log the asynchronous scheduler actions (config and log)
|
|
||||||
0x00100000 Log all open and close actions to /proc/net/hysdn/card files
|
|
||||||
0x00200000 Log all actions from /proc file entries
|
|
||||||
0x00010000 Log network interface init and deinit
|
