Arch Linux User Repository

Yes, it is backward compatible with older kernels (the patch only apply for kernels 5.10+). I don't have time to test it extensively right now but it worked fine for the 5-10 min I used it yesterday.

@goldensuneur Is it backward compatible with kernel 5.9, 5.4, etc? Does it work fine on kernel 5.10? I have not upgraded the kernel to 5.10 and really do not want to waste time to test it.

Latest available version of the module does not build with kernel 5.10+ due to removal of get_fs and set_fs functions.

I contacted Magewell support and they gave me a link to a fixed version (4227): http://www.magewell.com/files/drivers/ProCaptureForLinux_4227.tar.gz

It builds fine on kernel 5.10+ however I'm not able to reboot to test it right now.

I also modified your PKGBUILD to directly use the archive from Magewell instead of a github repository.

Here is the patch:
