PVR card integration

[eflothmeier]

I have a PVR card:

02:0a.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416)

... and the best approximation in the 3.17.7 kernel is:

<M> Conexant cx25821 support
<M> Conexant 25821 DMA audio support

I also have:

[*] Analog TV support


I still have no luck integrating this. It would be encouraging
to see a device node that looks like this:

/dev/video0

At least that was what I saw when this box was in an earlier
universe. That is, I've shelved the drives that once worked
in this old box, got new drives and upgraded with new s/w.

Can old h/w be integrated into new s/w?

you probably try to use the wrong driver and you might need some firmware; check here (chip seems similar to yours: http://openbenchmarking.org/linux/PCI/0400/4444:0016 )
from this it also seems the devnode might be called ivtv.

i could only check with kernel 3.18.5 (on ~amd64) and there is a driver that exactly fits your chipset:

[eflothmeier]

Interesting,
I'll bet I have the e-build for that kernel. It's in beta
status (~x86) right?

yes, 3.18 is still considered ~unstable.
but the driver also exists in 3.17.8-gentoo-r1 stable, i just checked it.
before you can select the different pci-adapters you have to select Analog, Digital TV and Remote Controller support:

[eflothmeier]

I did some digging and discovered these are already in 3.17.7

I have:
Media drivers
#
CONFIG_MEDIA_USB_SUPPORT=y

#
# Analog TV USB devices
#
CONFIG_VIDEO_PVRUSB2=y
CONFIG_VIDEO_PVRUSB2_SYSFS=y
.
.
# Analog/digital TV USB devices
#

#
# Webcam, TV (analog/digital) USB devices
#
# CONFIG_VIDEO_EM28XX is not set
CONFIG_MEDIA_PCI_SUPPORT=y
.
.
# Supported MMC/SDIO adapters
#
CONFIG_VIDEO_CX2341X=y
CONFIG_VIDEO_TVEEPROM=y
# CONFIG_CYPRESS_FIRMWARE is not set
.
.
and...

# Audio decoders, processors and mixers
#
CONFIG_VIDEO_MSP3400=y
CONFIG_VIDEO_CS53L32A=y
CONFIG_VIDEO_WM8775=y

#
# RDS decoders
#

#
# Video decoders
#
CONFIG_VIDEO_SAA711X=y

However we're still not out of the woods yet. There's IVTV
under the old regime there was:

However, that has now disappeared. But we still have:

Under the old regime the kernel features were installed as modules.
New kernels seem to discourage the use of modules, however.

Thanks for getting back to me. Sorry I'm slow at responding.
I'm a very careful person.

That driver has been around forever, since at least kernel 2.6 days. Search for CONFIG_VIDEO_IVTV. IIRC, you have to enable remote control to see it in the menu, even if you are not using the remote control. Post the results of 'dmesg | grep ivtv'.

See info here: http://ivtvdriver.org/index.php/Supported_hardware

Is your card a Hauppauge PVR-150/250/350 or something else?

[eflothmeier]

It's a PVR-150
No, That isn't set yet:
so there's nothing right now in the dmesg:

Symbol: VIDEO_IVTV [=n]
Type : tristate
Prompt: Conexant cx23416/cx23415 MPEG encoder/decoder support
Location:
-> Device Drivers
-> Multimedia support (MEDIA_SUPPORT [=y])
(2) -> Media PCI Adapters (MEDIA_PCI_SUPPORT [=y])
Defined at drivers/media/pci/ivtv/Kconfig:1
Depends on: MEDIA_SUPPORT [=y] && MEDIA_PCI_SUPPORT [=y] && MEDIA_ANALOG_TV_SUPPORT [
Selects: I2C_ALGOBIT [=y] && VIDEO_TUNER [=y] && VIDEO_TVEEPROM [=y] && VIDEO_CX2341X

I might also need

Symbol: VIDEO_IVTV_ALSA [=n]
Type : tristate
Prompt: Conexant cx23415/cx23416 ALSA interface for PCM audio capture

If it isn't specifically for cx23416, I don't want to set it. Like for example:

Symbol: VIDEO_FB_IVTV [=n]
Type : tristate
Prompt: Conexant cx23415 framebuffer support

Success.

My software configuration can now access the PVR-150:
Thanks for the advice for configuring the kernel.

First, I have:

mmom ~ # lsmod

nvidia_agp 3832 0

The modules loaded without my intervention. Just the same
my /etc/conf.d/modules file has:

crw-rw----+ 1 root video 81, 1 Feb 20 17:59 video32

in /dev

I also have:

* dev-perl/Video-ivtv

* media-tv/ivtv-utils

* sys-firmware/ivtv-firmware

installed

There's another problem, but it's not related to PVR-150
More on that later.
