It fails to compile the DKMS module with GCC 8.1.1+20180531 and/or kernel 4.16.13-2, not sure which one is the culprit.
Apparently it can't find the stdarg.h header file, did something get botched with the GCC update?
Edit: It still works with GCC 8.1.0
Edit2: Nevermind, removing and reinstalling decklink fixed the issue somehow.
Updated to 10.10, it did compile for 4.16 (and device gets listed)
I had the same problem, but I just had to rebuild the module to make it work again.
DKMS had built the module for the wrong kernel version.
I am currently on kernel 4.16.9-1-ARCH.
I rebooted my pc yesterday, and sadly my decklink device is once again not found.
It was working great on the normal kernel for quite a long time.
I also see it is flagged out of date and there is indeed a newer version.
Sure hope this update fixes the problem,
for now i will try the LTS kernel, i will post back here if that does not work.

Just grabbed this, works fine for me, I'm using a PCI Intensity Pro card.
did a little
$ modprobe blackmagic
booted up OBS and the card showed up, plugged in my switch, everything worked, no input delay.
Thanks for this package!
ps: I'm on kernel 4.14.15, hopefully it doesn't stop working after I update, You'll hear from me if it stops working.
This is pretty funny to watch, tbh.
Okay, so right now linux-lts (which just switched to 4.14) is the only working version.
TT;DR (too technical, didn't read): Linux 4.15 doesn't work with Blackmagic anymore because it removed some ancient code that Blackmagic still uses.
-
Uninstalled my previous hacky driver install as the Blackmagic was no longer recognized after a reboot. Tried to reinstall with the current version and ran into an error - as of 4.15.1, an old timer interface is removed.
If Blackmagic wants to get their code working on new Linux kernels, they need to replace the end of bm_timer_alloc at bm_util.c line 420 with
timer_setup(timer, (void(*)(bm_timer_t*))callback, 0);
return timer;
instead of the init_timer line and followup. Unfortunately this will break any code using the driver as it breaks expected behavior (data becomes unused, the callback gets sent a pointer to the timer instead), but that's on them. Trying to patch it like this and install leads to a crash as soon as the module blackmagic-io is inserted into the kernel, telling me I missed something probably. I couldn't find any use of this function in the driver code, though. It's likely a problem in Blackmagic's other software expecting certain behavior from the driver which necessarily changes due to this fix.
I tried to patch dkms.conf to fix the path, but it's still not being called. It looks to be doing depmod && modprobe anyway, which we are also doing.
We need a dkms guru to sed/patch it so that dkms install and dkms remove do work. Currently i'm unsure whether the dkms stuff even has any effect at all (and the install script is doing everything by hand).
If anyone is interested, the files are in /usr/src/blackmagic-10.9.10a2/
I reworked the install script to cleanup better (e.g. remove /usr/src/blackmagic-*); please feedback it the thing also works for you. Seems to work for me. But this package is looking more and more like frankenstein.

I finally had time to investigate the issue. It looks like that as of 11.5, the
DesktopVideoHelper.servicehas to be running for the capture card to work properly.
