PCI-E Passthrough not matching

[mr44er]

The x1-Slot is open on the back, so I would put in the X710-DA2 if there is no other thing in the way (battery socket maybe?). The performance penalty is not really bad to PCIE 5.0 x1, it should be enough to saturate 1 SFP+port.
But you can then have the tuner in the cpu group!

The X710-DA2 only got PVE 3.0 8x. It won't profit of the PCIe 5.0 and will only run as PCIe 3.0 1x, which means max 1 GB/s bandwidth. So you won't get more than 4Gbit per port. Probably even less.

Are you saying that Linux passthrough is more successful? Technically this is a "network" tuner so if I setup a VM on ProxMox and added it there and made it available on a private network to the virtual server wonder if that would work.

It is my experience that open source drivers handle partially initialized devices and differences in PCI(e) layout better than Windows drivers. On the other hand, many TV tuners don't work with Linux or there is no required firmware available. Passthrough is a niche and not something the manufacturers test for. You always need to search for success stories before buying hardware that you want to passthrough.

OK folks, got an interesting potential. I was able to compile some old (isn't everything for this card old) Linux drivers for the Ceton InfiniTV 4 within the ProxMox OS. It's now showing up in the ProxMox GUI and in the terminal session as an available network device. So in theory now InfiniTV give or take the cablecard install yet is broadcasting on it's own subnet (192.168.200.200/24) the network tuners.

That said, if I setup a Windows virtual on a different subnet device tied to the physical network card (192.168.1.x/24), would the computer see both? I know the ProxMox terminal session I can ping them obviously but outside of ProxMox on my desk PC no but that may or may not be a firewall thing.
