linux DeckLink kernel modules

I noticed that 2 different kernel modules are built when I install the debian package, (1) blackmagic, and (2) blackmagic_io

What is the difference between these 2 and should they both be installed?

dkms status shows this:
blackmagic, 10.4a17, 3.2.0-4-amd64, x86_64: installed
blackmagic, 10.4a17, 3.2.0-4-rt-amd64, x86_64: installed
blackmagic-io, 10.4a17, 3.2.0-4-amd64, x86_64: installed
blackmagic-io, 10.4a17, 3.2.0-4-rt-amd64, x86_64: installed

and lsmod only shows this:
blackmagic_io 389521 0

Is this correct or should both modules be loaded?

I still cannot get this fresh install debian 7.8 box to recognize this new SDI 4K card. When I run the DeviceList Sample program it reports that No Blackmagic Design devices were found.

Thanks,

As far as I know the blackmagic and blackmagic-io modules support different cards. The rt versions are for the real-time kernel. My system (Ubuntu 14.04LTS) only has one module loaded.

dkms status:
blackmagic, 10.3.7a4, 3.13.0-32-generic, x86_64: installed
blackmagic-io, 10.3.7a4, 3.13.0-32-generic, x86_64: installed

lsmod |grep blackmagic:
blackmagic 577354 1

What is the output from "BlackmagicFirmwareUpdater status"?
My system reports 0: /dev/blackmagic/dv0 [DeckLink Optical Fiber] 0x0b OK

Thanks for your response Dave.

On one of my development boxes I have this:

BlackmagicFirmwareUpdater status
0: /dev/blackmagic/dv1 [DeckLink SDI] 0x31 OK
1: /dev/blackmagic/dv0 [DeckLink SDI] 0x31 OK
2: /dev/blackmagic/dv2 [DeckLink Studio 2] 0x10 OK
3: /dev/blackmagic/dv3 [Intensity Pro] 0x25 OK
4: /dev/blackmagic/io0 [DeckLink SDI 4K] 0x7d OK

lsmod | grep magic
blackmagic_io 421760 1
blackmagic 577681 4

This box is running Ubuntu 13.10 and I was able to update this box to the recent 10.4 SDK--all appears to be running well on this box. However, I have just setup a newer development box with a fresh install of debian 7.8 and I am having problems getting things working on this box. On this debian box:

lsmod | grep magic
blackmagic_io 389521 0
blackmagic 561496 0

sudo dkms status
blackmagic, 10.4a17, 3.2.0-4-amd64, x86_64: installed
blackmagic-io, 10.4a17, 3.2.0-4-amd64, x86_64: installed

However, both "BlackmagicFirmwareUpdater status" and "lspci | grep magic" return without any messages, that is, neither success nor error messages.

Your lsmod indicated the modules are loaded but nothing is using them. Does dmesg offer any clues?

dave@OpenGL-Test-System-2:~$ dmesg |grep black
[ 37.974494] blackmagic: Loading driver (version: 10.3.7a4)
[ 41.342795] blackmagic: Successfully loaded device "blackmagic!dv0" [pci@0000:02:00.0]

Are you able to swap cards between systems or the OS drive from a working system?

Regards,

Dave.
