Thanks for answering, Marko.
And sorry for asking a maybe stupid question - how do I turn on the
debug output?
There is no such option in make menuconfig, and modinfo -p mantis only returns:
verbose:verbose startup messages, default is 1 (yes)
I emailed this to Manu Abraham too, because he is the main author for mantis drivers.
You can do:
rmmod mantis
modprobe mantis verbose=7
I have hardware:
[ 4487.836265] Mantis 0000:05:05.0: PCI INT A -> Link[APC3] -> GSI 18 (level, low) -> IRQ 18
[ 4487.837955] DVB: registering new adapter (Mantis DVB adapter)
[ 4487.869550] IR RC5(x) protocol handler initialized
[ 4487.923905] IR RC6 protocol handler initialized
[ 4487.940785] IR JVC protocol handler initialized
[ 4487.953168] IR Sony protocol handler initialized
[ 4487.974220] lirc_dev: IR Remote Control driver registered, major 249
[ 4487.990015] IR LIRC bridge handler initialized
[ 4488.697914] TDA10021: i2c-addr = 0x0c, id = 0x7c
[ 4488.697931] DVB: registering adapter 0 frontend 0 (Philips TDA10021 DVB-C)...
[ 4831.498140] Mantis 0000:05:05.0: PCI INT A disabled
Here is what comes with verbose=7:
...
[ 4890.486686] -- Stat=<4000800> Mask=<800> --<IRQ-1>
[ 4890.486695] mantis_uart_read (0): Reading ... <26>
[ 4890.486704] mantis_uart_work (0): UART BUF:0 <26>
[ 4890.486708]
[ 4890.486714] mantis_uart_read (0): Reading ... <26>
[ 4890.486719] mantis_uart_work (0): UART BUF:0 <26>
So this means, that my remote control works, pressing key with hex value 0x26 works.
Unfortunately mantis_uart.c doesn't have IR input initialization at all,
so the remote control button press is just ignored in mantis_uart.c:mantis_uart_work() function.
So this is partially implemented in mantis driver, No UART can work with Mantis in vanilla kernel.
You can try to check mantis directory and mantis_uart.c, and see if there are some input_device_XXX functions.
A good reference for implementation might be media/dvb/ttpci/av7110_ir.c: it looks like a working implementation with input device
support.

In general, should the remote control appear as an input device (like
it used to with the old, not-merged mantis driver) or is it possible
that the approach has changed to an LIRC-driver where no input device
is created?
Also: your mail suggests that support may just be broken in the
mainline kernel. In that case the info from the DVB wiki would just be
incorrect and I would be looking for a solution that does not exist -
is that just a hunch or do you acutally know it's not working?

Hi,
despite lots of time spent tinkering around and looking for help on
the web, I've had no success in getting to work the remote control of
my DVB-C card.
It is a Terratec Cinergy C:
http://linuxtv.org/wiki/index.php/TerraTec_Cinergy_C_DVB-C
and am using the Mantis driver. Since it was merged into the kernel
tree in 2.6.33, watching TV works without patches, but the remote
control does not, although it is supposed to be supported, according
to the link above.
Kernel is a vanilla 2.6.37.2 with custom configuration on an old AMD
Athlon XP machine, running debian Squeeze.
When I modprobe the Mantis driver, the following IR-modules are pulled
in automagically:
ir_lirc_codec
lirc_dev
ir_core
However, no input device is created during module loading. dmesg output:
Mantis 0000:01:0a.0: PCI INT A -> Link[APC1] -> GSI 16 (level, high) ->
IRQ 16
DVB: registering new adapter (Mantis DVB adapter)
IR LIRC bridge handler initialized
DVB: registering adapter 0 frontend 0 (Philips TDA10023 DVB-C)...
Am I missing some additional modules? Are there any dependencies on
other kernel config options that are not handled automatically by make
menuconf?
If additional information is needed, I will be happy to provide it.
However, I am not sure what is useful and what is not and did not want
to bloat this message.
Before merging into v4l-dvb, doing modprobe mantis was enough.
I don't know how it should work with recent kernels.
I haven't seen remote control working lately.
Turning mantis module debug options on gives some information
what is happening into /var/log/messages.
Regards,
Marko Ristola
Thanks in advance,
Jonas
