Arch Linux User Repository

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

Sadly it does not build, Failed to download. It gives an error unable to resolve host: invalid request to download. Also manually downloading the file and putting it in the makepkg folder does not work. It would be a nice add to the PKGBUILD to search for local files so that the curl download is not necessary whenever blackmagic desides to change urls. Thanks And Greets

I know, said it below: you need linux-lts to have the driver working, not the latest linux package.

I confirm that it finally works ! gst-launch-1.0 decklinkvideosrc device-number=1 connection=1 mode=16 ! xvimagesink

After a reboot, the device firmware updater reports the device to be up to date.

So it still fails on the current linux, but does compile on linux-lts (4.9.22-1-lts). So you need the linux-lts and linux-lts-headers packages. Device flashing did reportedly fail however, even if the dmesg doesn't report failure [ 89.800430] blackmagic: loading out-of-tree module taints kernel.

Got news: "I am pleased to advise that the recently released Desktop Video 10.8.6 includes the correction for the compilation issue on kernel 4.9+." Testing now

Damn, they should hopefully fix it when Debian/Ubuntu relase the new versions with kernels >= 4.8.

I'm afraid it's even worse, it doesn't compile against 4.9.11-1; note that the driver was not updated, just the desktop app. make -C /lib/modules/`uname -r`/build M=/usr/src/blackmagic-io-10.8.5a4 make[1]: Entering directory '/usr/lib/modules/4.9.11-1-ARCH/build' CC [M] /usr/src/blackmagic-io-10.8.5a4/bm_mm.o /usr/src/blackmagic-io-10.8.5a4/bm_mm.c: In function 'bm_get_user_pages': /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:108:85: error: passing argument 5 of 'get_user_pages' from incompatible pointer type [-Werror=incompatible-pointer-types] ret = get_user_pages((unsigned long)address & PAGE_MASK, umem->length, write, 0, umem->pages, NULL); ^~~~ In file included from /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:27:0: ./include/linux/mm.h:1280:6: note: expected 'struct vm_area_struct **' but argument is of type 'struct page **' long get_user_pages(unsigned long start, unsigned long nr_pages, ^~~~~~~~~~~~~~ /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:108:10: error: too many arguments to function 'get_user_pages' ret = get_user_pages((unsigned long)address & PAGE_MASK, umem->length, write, 0, umem->pages, NULL); ^~~~~~~~~~~~~~ In file included from /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:27:0: ./include/linux/mm.h:1280:6: note: declared here long get_user_pages(unsigned long start, unsigned long nr_pages, ^~~~~~~~~~~~~~ /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:110:108: error: passing argument 7 of 'get_user_pages_remote' from incompatible pointer type [-Werror=incompatible-pointer-types] ret = get_user_pages_remote(task, task->mm, (unsigned long)address & PAGE_MASK, umem->length, write, 0, umem->pages, NULL); ^~~~ In file included from /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:27:0: ./include/linux/mm.h:1276:6: note: expected 'struct vm_area_struct **' but argument is of type 'struct page **' long get_user_pages_remote(struct task_struct *tsk, struct mm_struct *mm, ^~~~~~~~~~~~~~~~~~~~~ /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:110:10: error: too many arguments to function 'get_user_pages_remote' ret = get_user_pages_remote(task, task->mm, (unsigned long)address & PAGE_MASK, umem->length, write, 0, umem->pages, NULL); ^~~~~~~~~~~~~~~~~~~~~ In file included from /usr/src/blackmagic-io-10.8.5a4/bm_mm.c:27:0: ./include/linux/mm.h:1276:6: note: declared here long get_user_pages_remote(struct task_struct *tsk, struct mm_struct *mm, ^~~~~~~~~~~~~~~~~~~~~ cc1: some warnings being treated as errors make[2]: *** [scripts/Makefile.build:294: /usr/src/blackmagic-io-10.8.5a4/bm_mm.o] Error 1 make[1]: *** [Makefile:1490: _module_/usr/src/blackmagic-io-10.8.5a4] Error 2 make[1]: Leaving directory '/usr/lib/modules/4.9.11-1-ARCH/build' make: *** [Makefile:47: all] Error 2

10.8.5 is out, I want to believe.
