decklink extreme pci-express

trying to run a decklink extreme pci-express board on a dell r200 server ... with no luck

that's my lspci output:
02:00.0 Multimedia video controller: Blackmagic Design Device a118 (rev 0e)

my dmesg|grep -i black
[ 9.026070] blackmagic: module license 'Proprietary' taints kernel.

[ 9.027447] blackmagic: Loading driver (version: 10.1.1a26)

lsmod | grep blackmagic
blackmagic 571667 0

i modded the vmalloc in grub so my cat /proc/memifo returns
...
VmallocTotal: 34359738367 kB

VmallocChunk: 34359435264 kB
...


but BlackmagicFirmwareUpdater status
returns nothing ....
and no blackmagic device in /dev ...

What could do also?

How can i update the firmware?

It's possible that you should be loading the blackmagic-io.ko driver instead of the blackmagic.ko driver.

It turns out that blackmagic-io.ko is used by the newer 4K boards, whereas blackmagic.ko is used by everything else.

This vital piece of information is seemingly not documented anywhere.

Thank you. I had this same problem and your advice solved it. The documentation really needs to be updated to show that the blackmagic-io driver is the one to load on the newer cards.

I'm not against better documentation and its good that loading a specific module manually has solved the problem.

However another question is why the module hasn't been loaded automatically? The desktopvideo package provides a udev rule so that the correct module can be loaded automatically at boot time if the relevant hardware is detected. I wonder why that hasn't happened in your case ..

In my case, it didn't autoload because I hadn't rebooted yet. I was following the documentation and it said to use blackmagic.ko so that's what I did. I eventually figured out that this was wrong and the udev rule did activate after a reboot.
